NHTSA Interpretation File Search

Overview

NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies. 

Understanding NHTSA’s Online Interpretation Files

NHTSA makes its letters of interpretation available to the public on this webpage. 

An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.

  • Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
  • Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
  • The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
  • Some combination of the above, or other, factors.

TEXT:

This responds to your letter of April 2, 1992 concerning possible interpretations of section S5.1.4(c) of Federal Motor Vehicle Safety Standard No. 222, School bus passenger seating and crash protection, as it applies to the R-BAR Passenger Restraint System (R-BAR). (While your letter refers to section S5.1.2(c), you clarified in a telephone conversation with Mary Versailles of my staff that your concerns relate to section S5.1.4(c).) The R-BAR is a padded restraining device, and the ends of the device attach to the rear of a school bus seatback. The device folds down for the purpose of restraining the passengers seated in the next rearward seat. Your letter states that Micho Industries believes that:

A. The standard is not applicable to the R-BAR passenger restraint.

B. The R-BAR complies with the intent of Standard No. 222.

To support these statements you offer the following reasons:

1. The R-BAR is not a fixed position device, nor is it a rigid component of the seat structure.

2. In the event of a rear impact, the R-BAR incorporates a design that allows it to move upward, and away, from the adjoining seat which would thus allow the minimum clearance as intended.

3. The standard in question (571.222, section S5.1.4(c)) was written without the authors having the benefit of knowledge of this type of device and thus allowances were not included for its possible use.

The issue of whether Standard No. 222 is applicable to a device such as the R-BAR has been addressed previously by this agency. Enclosed are copies of four letters concerning similar devices (Mr. Joseph F. Mikoll, November 3, 1988, and March 10, 1989; The Honorable Robert J. Lagomarsino, January 8, 1990; and Mr. Scott K. Hiler, January 31, 1991). Those letters make it clear that if a device such as the R-BAR is installed in any new school bus, the school bus manufacturer must certify that the vehicle meets all applicable safety standards with the device installed. The letters also make it clear that such devices may not legally be installed in used school buses by commercial establishments such as repair businesses if the effect of such installation is

to take the vehicle out of compliance with any safety standard.

With respect to your assertion that the R-BAR complies with the intent of Standard No. 222, the National Traffic and Motor Vehicle Safety Act requires NHTSA to issue Federal motor vehicle safety standards that prescribe objective requirements. Under the Act, manufacturers must certify that their products comply with the requirements of all applicable standards and not merely with some alleged "intent" of a standard. Further, manufacturers may not certify products based on speculation that the agency would have established different requirements had it known of a particular design.

With regard to your specific concerns about S5.1.4(c), that section states that when a seat back is subjected to a specified force, "(t)he seat shall not deflect by an amount such that any part of the seat moves to within 4 inches of any part of another passenger seat in its originally installed position." In the enclosed letter to Mr. Hiler, the agency stated that "once the restraining bar is attached to the seatback, it is part of the seatback." Therefore, the R-BAR would be considered a part of the seat subject to the requirements of S5.1.4.(c)

Section S5.1.4(c)'s requirements are not limited to rigid components of a seat, and therefore the fact that the R-BAR is not a fixed position device is not relevant to the applicability of those requirements. With respect to your argument that the device will move upward and away in the event of a rear impact, Standard No. 222 sets forth a specific test procedure for the requirement specified in S5.1.4(c). Manufacturers are required to certify that a vehicle complies with the requirements of the standard when tested in accordance with that test procedure.

I hope you find this information helpful. If you have any other questions, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992.

TEXT: Dear Mr. Sharples

I enclose a copy of an order of the Administrator granting the petition by Cantab Motors for temporary exemption from Motor Vehicle Safety Standards Nos. 208 and 214. The exemption from Standard No. 208 will expire on September 1, 1997, and that for Standard No. 214 on September 1, 1998.

In accordance with agency regulations on the subject, within 30 days after your receipt of this letter please provide the Director, Office of Vehicle Safety Compliance, with a copy of the certification label reflecting the exemption that will be used on Cantab's vehicles (49 CFR 555.9(a)).

We have received your letter of August 17, 1995, which admits that Cantab manufactured and sold nine vehicles manufactured after the expiration of its previous exemption that did not conform with Standard No. 208, and which enclosed a petition for a determination of inconsequentiality on this matter. This is currently under review.

If you have any questions, you may discuss them with Taylor Vinson of this Office (202-366-5263).

Enclosure

ACTION: Issuance of Federal Register Notice Granting Cantab's Petition for Temporary Exemption From Standards Nos. 208 and 214 John Womack (K. WEINSTEIN) Acting Chief Counsel

Barry Felrice Associate Administrator for Safety Performance Standards

Attached for your signature is a Federal Register notice granting the petition by Cantab Motors for a temporary exemption from the automatic restraint requirements of Standard No. 208, and the side impact protection requirements of Standard No. 214. The basis of the grant is that compliance would cause substantial economic hardship to a manufacturer that has tried in good faith to meet the standards.

Cantab imports shells of Morgan sports cars from England, and installs propane engines and drive trains in the US; for this reason, we consider Cantab rather than Morgan as the manufacturer. In the year preceding the filing of its exemption petition it produced only 9 such cars. It has cumulative net losses approaching $ 93,000 for the last three fiscal years. It has been working with Morgan to develop vehicles that will be equipped with airbags meeting Standard No. 208, and provide side impact protection meeting Standard No. 214.

Because the components that must be modified for conformance are under the control of Morgan rather than Cantab, the company is dependent upon Morgan's efforts. Cantab asked for only a 2-year exemption from Standard No. 208, indicating that it is optimistic that its cars will conform in less than the 3 years it could have asked for. However, it appears to require the full 3 years for Standard No. 214.

Any threat to safety that would be presented by an exempted vehicle would be minimal because they are few in number, and are represented as conforming to earlier versions of the two standards.

No comments were received on the application.

Docket No. 95-53; Notice 2

Cantab Motors, Ltd.

Grant of Application for Temporary Exemption From

Federal Motor Vehicle Safety Standards No. 208 and 214

Cantab Motors, Ltd., of Round Hill, Va., applied for a temporary exemption of two years from paragraph S4.1.4 of Federal Motor Vehicle Safety Standard No. 208 Occupant Crash Protection, and for three years from Federal Motor Vehicle Safety Standard No. 214 Side Impact Protection. The basis of the application was that compliance will cause substantial economic hardship to a manufacturer that has tried to comply with the standard in good faith.

Notice of receipt of the application was published on July 14, 1995, and an opportunity afforded for comment (60 FR 36328).

The make and type of passenger car for which exemption was requested is the Morgan open car or convertible. Morgan Motor Company ("Morgan"), the British manufacturer of the Morgan, has not offered its vehicle for sale in the United States since the early days of the Federal motor vehicle safety standards. In the nine years it has been in business, the applicant has bought 35 incomplete Morgan cars from the British manufacturer, and imported them as motor vehicle equipment, completing manufacture by the addition of engine and fuel system components. They differ from their British counterparts, not only in equipment items and modifications necessary for compliance with the Federal motor vehicle safety standards, but also in their fuel system components and engines, which are propane fueled. As the party completing manufacture of the vehicle, Cantab certifies its conformance to all applicable Federal safety and bumper standards. The vehicle completed by Cantab in the U.S. is deemed sufficiently different from the one produced in Britain that NHTSA considers Cantab the manufacturer, not a converter, even though the brand names are the same.

Morgan itself produced 478 cars in 1994, while in the year preceding the filing of its petition in June 1995, the applicant produced 9 cars for sale in the United States. Since the granting of its original exemption in 1990, Cantab has invested $ 38,244 in research and development related to compliance with Federal safety and emissions standards. The applicant has experienced a net loss in each of its last three fiscal (calendar) years, with a cumulative net loss for this period of $ 92,594.

Application for Exemption from Standard No. 208

Cantab received NHTSA Exemption No. 90-3 from S4.1.2.1 and S4.1.2.2 of Standard No. 208, which expired May 1, 1993 (55 FR 21141). When this exemption was granted in 1990, the applicant had concluded that the most feasible way for it to conform to the automatic restraint requirements of Standard No. 208 was by means of an automatically deploying belt. In the period following the granting of the exemption, Morgan and the applicant created a mock-up of the Morgan passenger compartment with seat belt hardware and motor drive assemblies. In time, it was determined that the belt track was likely to deform, making it inoperable. The program was abandoned, and Morgan and Cantab embarked upon research leading to a dual airbag system.

According to the applicant, Morgan tried without success to obtain a suitable airbag system from Mazda, Jaguar, Rolls-Royce and Lotus. As a result, Morgan is now developing its own system for its cars, and "[as] many as twelve different sensors, of both the impact and deceleration (sic) type, have been tested and the system currently utilizes a steering wheel from a Jaguar and the Land Rover Discovery steering column." Redesign of the passenger compartment is underway, involving knee bolstering, a supplementary seat belt system, antisubmarining devices, and the seats themselves. Morgan informed the applicant on May 2, 1995, that it had thus far completed 10 tests on the mechanical components involved "and are now carrying out a detailed assessment of air bag operating systems and columns before we will be in a position to undertake the full set of appropriate tests to approve the installation in our vehicles."

Application for Exemption from Standard No. 214

Concurrently, Morgan and the applicant have been working towards meeting the dynamic test and performance requirements for side impact protection, for which Standard No. 214 has established a phase-in schedule. Although Morgan fits its car with a dual roll bar system specified by Cantab, and Cantab installs door bars and strengthens the door latch receptacle and striker plate, the system does not yet conform to the new requirements of Standard No. 214, and the applicant has asked for an exemption of three years. It does, however, meet the previous side door strength requirements of the standard. Were the phase-in requirement of S8 applied to it, calculated on the basis of its limited production, only very few cars would be required to meet the standard.

Safety and Public Interest Arguments

Because of the small number of vehicles that the applicant produces and its belief that they are used for pleasure rather than daily for business commuting or on long trips, and because of the three-point restraints and side impact protection currently offered, the applicant argued that an exemption would be in the public interest and consistent with safety. It brought to the agency's attention two recent oblique front impact accidents at estimated speeds of 30 mph and 65 mph respectively in which the restrained occupants "emerged unscathed."

Further, the availability "of this unique vehicle . . . will help maintain the existing diversity of motor vehicles available to the U.S. consumer." Finally, "the distribution of [this] propane-fueled vehicle has contributed to the national interest by promoting the development of motor systems by using alternate fuels."

No comments were received on the application.

In adding only engine and fuel system components to incomplete vehicles, the applicant is not a manufacturer of motor vehicles in the conventional sense. It does not produce the front end structural components, instrument panel, or steering wheel, areas of the motor vehicle whose design is critical for compliance with the airbag requirements of Standard No. 208. These are manufactured by Morgan, and the applicant is necessarily dependent upon Morgan to devise designs that will enable conformance with Standard No. 208. The applicant has been monitoring Morgan's progress, and that company is engaging in testing and design activities necessary for eventual conformance. The fact that the applicant is requesting only a two-year exemption, rather than three, indicates its belief that complying operator and passenger airbags will at last be fitted to its cars by the end of this period.

Similarly, the applicant is dependent upon the structural design of its vehicle for compliance with Standard No. 214. As with Standard No. 208, Morgan and the applicant are working towards conformance, though apparently it will not be achieved within two years. In both instances, however, the applicant is conscious of the need to conform and has been taking steps to accomplish it. Although the company's total expenditure of $ 38,244 in the last five years to meet emission and safety requirements is low, the small number of cars produced for sale in the United States in the last year, nine, would not make available substantial funds to the company, and its cumulative net losses of $ 92,594 indicate an operation whose financial existence is precarious.

Applicant's cars are equipped with manual three-point restraint systems and comply with previous side impact intrusion requirements. Because applicant produces only one line of vehicles, it cannot take advantage of the phase-in requirement. Given the existing level of safety of the vehicles and the comparatively small exposure of the small number of them that would be produced under an exemption, there would appear to be an insignificant risk to traffic safety by providing an exemption. The public interest is served by maintaining the existence of small businesses and by creating awareness of alternative power sources.

In consideration of the foregoing, it is hereby found that to require immediate compliance with Standards Nos. 208 and 214 would cause substantial economic hardship to a manufacturer that has in good faith attempted to meet the standards, and that an exemption would be in the public interest and consistent with the objectives of traffic safety.

Accordingly, the applicant is hereby granted NHTSA Exemption No. 95-2, from paragraph S4.1.4 of 49 CFR 571.208 Motor Vehicle Safety Standard No. 208 Occupant Crash Protection, expiring September 1, 1997, and from 49 CFR 571.214 Motor Vehicle Safety Standard No. 214 Side Impact Protection, expiring September 1, 1998.

    Manager, Corporate Affairs
    Hyundai America Technical Center, Inc.,
    5075 Venture Drive
    Ann Arbor, MI 48108

    Dear Mr. Babcock:

    This responds to your request asking whether a driver and passenger safety belt reminder system under development by Hyundai violates any Federal motor vehicle safety standards. The Hyundai system, as described, is not prohibited by any such standards.

    According to your letter, the Hyundai system consists of a driver seat system that activates a visual reminder that remains lit whenever the ignition is turned to the "ON" position if the safety belt is not fastened and an audible alert that is activated one minute after the ignition is turned on. Both alerts cease once the safety belt is fastened. The passenger seat safety belt reminder system consists of a visible alert that activates whenever the ignition is in the "ON" position, the air bag occupant sensor system detects the presence of an occupant in the passenger seat, and the safety belt is unfastened. The visible alert turns off once the safety belt is fastened after the ignition has been turned on for 6 seconds. This 6-second activation is the result of the air bag system self-check protocol and, consequently, is unrelated to safety belt use. In your letter you note that such self-check systems are commonly used by vehicle manufacturers for other telltales or alerts.

    The only safety standard that could conceivably prohibit the Hyundai system is Federal Motor Vehicle Safety Standard No. 208, Occupant crash protection (FMVSS No. 208). S7.3 of that standard requires the driver's seating position be equipped with a safety belt warning system that activates, under specified circumstances, a continuous or intermittent audible signal for a period of "not less than 4 seconds and not more than 8 seconds," and a continuous or flashing warning light for not less than 60 seconds after the ignition switch is turned on if the safety belt is not buckled. The system described in your letter meets these criteria. A manufacturer may, at its option, reduce the period of the visual warning to 4 to 8 seconds if it is activated even when the safety belt is buckled.

    The provision in the standard establishing a maximum of 8 seconds for the audible signal reflects a statutory requirement imposed by Congress in response to public resistance to safety belt interlock systems. See House report 93-1452, pp.44-45. 49 U.S.C. 30124 provides, in relevant part, that a motor vehicle safety standard "may not require or allow a manufacturer to comply with the standard by...using...a buzzer designed to indicate a safety belt is not in use, except a buzzer that operates only during the 8-second period after the ignition is turned to the 'start' or 'on' position."

    While the statute prohibits the National Highway Traffic Safety Administration (NHTSA) from requiring, or specifying as a compliance option, an audible safety belt warning that sounds outside of the specified 8-second period, it does not prohibit vehicle manufacturers from placing such systems in their vehicles. However, given FMVSS No. 208's requirement that the required safety belt warning be no longer than 8 seconds, a vehicle manufacturer wishing to provide a voluntary audible signal must provide some means of differentiating the voluntarily-provided signal from the required signal. This is necessary so NHTSA can verify that the system installed to meet FMVSS No. 208 is compliant. One way to differentiate between the two signals is a clearly distinguishable lapse in time between the two signals. The Hyundai system, as described, only activates once the ignition has been turned to the "ON" position for 60 seconds and the driver safety belt remains unfastened. This time lapse is sufficiently long to make the second audible signal clearly distinguishable from the initial, required 8-second signal. Accordingly, the additional driver seat belt reminder system is permitted under the standard.

    FMVSS No. 208 does not regulate passenger safety belt reminder systems at all. Accordingly, there is no prohibition against the system you have described for that seating position. We generally would be concerned about a system that remained activated long after the safety belt was fastened. However, we believe that a total visual alert time of 6 seconds after the ignition is turned "ON" even when the safety belt is fastened is unlikely to distract or annoy the vehicle occupant.

    I hope this information addresses your concerns. If you have any further questions, please feel free to contact Rebecca MacPherson of my staff at (202) 366-2992.

Director, Automotive Safety Office
Environmental and Safety Engineering Staff

Dearborn, MI 48121

Dear Mr. Munson:

This responds to your letter in which you suggested that there are some apparently inconsistent provisions in Standard Nos. 208, Occupant Crash Protection (49 CFR /571.208) and 209, Seat Belt Assemblies (49 CFR /571.209). With respect to manual belt systems installed at front outboard seating positions in a vehicle which is certified as complying with the dynamic testing requirements in Standard No. 208, you asked whether those belt systems may be equipped with load limiters, such that the belt assembly does not comply with the elongation requirements in Standard No. 209. For the reasons explained below, the answer is no.

Your letter suggested that Standard No. 209 contains two different provisions that yield inconsistent answers to this question. On the one hand, section S4.5(b) of Standard No. 209 reads as follows: "A Type 1 or Type 2 seat belt assembly that includes a load limiter and that does not comply with the elongation requirements of this standard may be installed in motor vehicles only in conjunction with an automatic restraint system as part of a total occupant restraint system." Section S3 of Standard No. 209 defines a "load limiter" as "a seat belt assembly component or feature that controls tension on the seat belt to modulate the forces that are imparted to occupants restrained by the belt assembly during a crash." These provisions of Standard No. 209 seemingly preclude the use of a load limiter on manual belts, if the load limiter results in the belt assembly not complying with those elongation requirements, unless the seating position in which such manual belts is also equipped with an automatic restraint system. Accordingly, dynamically tested manual belts installed at seating positions that do not include any automatic restraint system could not be equipped with a load limiter, if the load limiter resulted in the belt no longer complying with the elongation requirements.

On the other hand, section S4.6 of Standard No. 209 exempts dynamically tested manual belts from the elongation requirements of the standard, as well as the webbing width and strength requirements. This exemption applies without respect to whether the dynamically tested manual belt is equipped with a load limiter. Ford suggests that this provision means that a manual belt installed at a front outboard seating position could be equipped with a load limiter, even if the load limiter resulted in the belt assembly not complying with the elongation requirements, provided that the vehicle in which the belt was installed was certified as complying with the dynamic testing requirements in Standard No. 208.

In your letter, you said that it was Ford's interpretation that the requirements of S4.6 of Standard No. 209 were meant to limit the prohibition in S4.5 of Standard No. 209, by permitting the use of load limiters that result in the belt assembly no longer complying with the elongation limits on either automatic belts or dynamically-tested manual belts. You suggested that the reasoning that caused the agency to limit the use of load limiters that result in the belt not complying with the elongation requirements to automatic belts only, in section S4.5, does not apply to dynamically tested manual belts. You quoted the following language from the notice that established S4.5:

[T]here are currently no dynamic performance requirements or injury criteria for manual belt systems used alone. There are no requirements to ensure that a load-limiting belt system would protect vehicle occupants from impacting the steering wheel, instrument panel, and windshield, which would be very likely if the belts elongated beyond the limits specified in Standard No. 209. Therefore, the elongation requirements are necessary to ensure that manual belts used as the sole restraint system will adequately restrain vehicle occupants. 46 FR 2618, at 2619; January 12, 1981.

You noted that this reasoning is now outmoded for some manual belts, because dynamic testing requirements have been established for certain manual belts. In fact, you asserted that the agency has expressly recognized this by exempting dynamically-tested manual belts from the elongation requirements of Standard No. 209. Accordingly, you believe that S4.5 of Standard No. 209 should be interpreted to permit the use of load limiters that cause the belt to no longer comply with the elongation requirements on either automatic belts or dynamically tested manual belts.

As further support for this position, your letter suggested that the agency's notices establishing dynamic testing requirements for manual belt systems show an intent to treat dynamically-tested manual belts in the same way as automatic belts for the purposes of Standard No. 209. You referred to our rule adopting dynamic testing requirements for manual safety belts in front outboard seating positions of passenger cars (51 FR 9800; March 21, 1986), the rule extending dynamic testing requirements to manual belts installed at front outboard seating positions of light trucks and multipurpose passenger vehicles (52 FR 44898; November 23, 1987), and the denial of petitions for reconsideration asking the agency to rescind the exemption of automatic belts and dynamically tested manual belts from the webbing width, strength, and elongation requirements of Standard No. 209 (53 FR 5579; February 25, 1988). Because of the agency's consistent expression in these three notices of its intent to treat dynamically tested manual belts in the same way automatic belts are treated under Standard No. 209, you believe that the reference in S4.5(b) of Standard No. 209 permitting load limiters on belts used "in conjunction with an automatic restraint system" should be interpreted to mean load limiters may be installed on belts used in conjunction with an automatic or dynamically tested manual restraint system.

I do not concur with your suggested interpretation. I believe that sections S4.5 and S4.6 yield inconsistent answers to your question. Section S4.6(a) exempts manual belts from elongation requirements. However, it does not speak to the consequence of installing a load limiter on a belt that does not comply with those requirements. Section S4.5(b) does speak to this issue. It says that such a belt may be used only in conjunction with an automatic restraint. To be more specific, section S4.5 expressly provides that a belt assembly that "includes a load limiter and that does not comply with the elongation requirements of this standard may be installed in a motor vehicle only in conjunction with an automatic restraint system as part of a total occupant restraint system."

I appreciate that the discussion you quoted from the 1981 notice is consistent with your argument that load limiters should be permitted on any dynamically-tested manual belt. Nevertheless, regardless of whether you believe that NHTSA intended to make or should have made such a change when in adopting dynamic testing requirements for manual belts, it is not possible to interpret the term "automatic restraint system," as used in S4.5, to mean "automatic restraint system or dynamically tested manual restraint system." An interpretation cannot add or delete requirements that are not contained in the language of the standard itself. When the agency promulgates a safety standard specifying performance requirements for vehicles or items of equipment to accomplish a particular safety purpose, that safety standard sets forth all the requirements with which the vehicles or equipment must comply. If the requirements in the safety standard do not fully address or ensure the implementation of some aspect of the underlying safety purpose, that aspect is not part of the standard. Since an interpretation cannot amend the language of a safety standard, the agency's only recourse in these situations is to undertake rulemaking to amend the language of the standard.

You asked that we treat your request for an interpretation as a petition for rulemaking if, as we have done, we concluded that your suggested interpretation was incorrect. We will notify you of our response to this petition as soon as we complete our review of it.

Sincerely,

TEXT: Dear Mr. Munson:

This responds to your letter in which you suggested that there are some apparently inconsistent provisions in Standard Nos. 208, Occupant Crash Protection (49 CFR @ 571.208) and 209, Seat Belt Assemblies (49 CFR @ 571.209).

Section S3 of Standard No. 2 09 defines a "load limiter" as "a seat belt assembly component or feature that controls tension on the seat belt to modulate the forces that are imparted to occupants restrained by the belt assembly during a crash." These provisions of Standard No. 209 s eemingly preclude the use of a load limiter on manual belts, if the load limiter results in the belt assembly not complying with those elongation requirements, unless the seating position in which such manual belts is also equipped with an automatic rest raint system. Accordingly, dynamically tested manual belts installed at seating positions that do not include any automatic restraint system could not be equipped with a load limiter, if the load limiter resulted in the belt no longer complying with the elongation requirements.

On the other hand, section S4.6 of Standard No. 209 exempts dynamically tested manual belts from the elongation requirements of the standard, as well as the webbing width and strength requirements. This exemption applies without respect to whether the d ynamically tested manual belt is equipped with a load limiter. Ford suggests that this provision means that a manual belt installed at a front outboard seating position could be equipped with a load limiter, even if the load limiter resulted in the belt assembly not complying with the elongation requirements, provided that the vehicle in which the belt was installed was certified as complying with the dynamic testing requirements in Standard No. 208.

In your letter, you said that it was Ford's interpretation that the requirements of S4.6 of Standard No. 209 were meant to limit the prohibition in S4.5 of Standard No. 209, by permitting the use of load limiters that result in the belt assembly no longe r complying with the elongation limits on either automatic belts or dynamically-tested manual belts. You suggested that the reasoning that caused the agency to limit the use of load limiters that result in the belt not complying with the elongation requ irements to automatic belts only, in section S4.5, does not apply to dynamically tested manual belts. You quoted the following language from the notice that established S4.5:

[There] are currently no dynamic performance requirements or injury criteria for manual belt systems used alone. There are no requirements to ensure that a load-limiting belt system would protect vehicle occupants from impacting the steering wheel, i nstrument panel, and windshield, which would be very likely if the belts elongated beyond the limits specified in Standard No. 209. Therefore, the elongation requirements are necessary to ensure that manual belts used as the sole restraint system will a dequately restrain vehicle occupants. 46 FR 2618, at 2619; January 12, 1981.

You noted that this reasoning is now outmoded for some manual belts, because dynamic testing requirements have been established for certain manual belts. In fact, you asserted that the agency has expressly recognized this by exempting dynamically-tested manual belts from the elongation requirements of Standard No. 209. Accordingly, you believe that S4.5 of Standard No. 209 should be interpreted to permit the use of load limiters that cause the belt to no longer comply with the elongation requirements on either automatic belts or dynamically tested manual belts.

As further support for this position, your letter suggested that the agency's notices establishing dynamic testing requirements for manual belt systems show an intent to treat dynamically-tested manual belts in the same way as automatic belts for the pur poses of Standard No. 209. You referred to our rule adopting dynamic testing requirements for manual safety belts in front outboard seating positions of passenger cars (51 FR 9800; March 21, 1986), the rule extending dynamic testing requirements to manu al belts installed at front outboard seating positions of light trucks and multipurpose passenger vehicles (52 FR 44889; November 23, 1987), and the denial of petitions for reconsideration asking the agency to rescind the exemption of automatic belts and dynamically tested manual

belts from the webbing width, strength, and elongation requirements of Standard No. 209 (53 FR 5579; February 25, 1988). Because of the agency's consistent expression in these three notices of its intent to treat dynamically tested manual belts in the s ame way automatic belts are treated under Standard No. 209, you believe that the reference in S4.5(b) of Standard No. 209 permitting load limiters on belts used "in conjunction with an automatic restraint system" should be interpreted to mean load limite rs may be installed on belts used in conjunction with an automatic or dynamically tested manual restraint system.

I do not concur with your suggested interpretation. I believe that sections S4.5 and S4.6 yield inconsistent answers to your question. Section S4.6(a) exempts manual belts from elongation requirements. However, it does not speak to the consequence of installing a load limiter on a belt that does not comply with those requirements. Section S4.5(b) does speak to this issue. It says that such a belt may be used only in conjunction with an automatic restraint. To be more specific, section S4.5 expressl y provides that a belt assembly that "includes a load limiter and that does not comply with the elongation requirements of this standard may be installed in a motor vehicle only in conjunction with an automatic restraint system as part of a total occupan t restraint system."

I appreciate that the discussion you quoted from the 1981 notice is consistent with your argument that load limiters should be permitted on any dynamically-tested manual belt. Nevertheless, regardless of whether you believe that NHTSA intended to make o r should have made such a change when in adopting dynamic testing requirements for manual belts, it is not possible to interpret the term "automatic restraint system," as used in S4.5, to mean "automatic restraint system or dynamically tested manual rest raint system." An interpretation cannot add or delete requirements that are not contained in the language of the standard itself. When the agency promulgates a safety standard specifying performance requirements for vehicles or items of equipment to acc omplish a particular safety purpose, that safety standard sets forth all the requirements with which the vehicles or equipment must comply. If the requirements in the safety standard do not fully address or ensure the implementation of some aspect of th e underlying safety purpose, that aspect is not part of the standard. Since an interpretation cannot amend the language of a safety standard, the agency's only recourse in these situations is to undertake rulemaking to amend the language of the standard .

You asked that we treat your request for an interpretation as a petition for rulemaking if, as we have done, we concluded that your suggested interpretation was incorrect. We will notify you of our response to this petition as soon as we complete our re view of it.

Sincerely,

Maine 04333;

"Dear Mr. Martin: This is in regard to your letter of December 9, 1991 regarding school buses. Your three questions are addressed below. 1. (W)hat is the general rule to which states need to comply with regarding Federal school bus safety standards? What bus safety modifications would not be restricted by 15 U.S.C. 1392(d)? Section 103(d) of the National Traffic and Motor Vehicle Safety Act (the Safety Act, 15 U.S.C. 1392(d)) provides that: Whenever a Federal motor vehicle safety standard ... is in effect, no State or political subdivision of a State shall have any authority either to establish, or to continue in effect, with respect to any motor vehicle or item of motor vehicle equipment any safety standard applicable to the same aspect of performance of such vehicle or item of equipment which is not identical to the Federal standard. Nothing in this section shall be construed to prevent ... any State or political subdivision thereof from establishing a safety requirement applicable to motor vehicles or motor vehicle equipment procured for its own use if such requirement imposes a higher standard than that required to comply with the otherwise applicable Federal standard. Section 103(d) preempts state requirements for school buses covering the same aspect of performance as an applicable Federal motor vehicle safety standard (FMVSS) that are different from the applicable FMVSS except to the extent that the requirements impose a higher level of performance and apply only to vehicles procured for the State's use. A state law imposing higher requirement would be preempted under 103(d) to the extent that the law requires all school buses manufactured for use in the state to comply with the law. The law would not be preempted to the extent that it applies to public school buses. The agency has previously interpreted the phrase 'vehicles procured for (the State's) own use' to include public school buses and school buses operated and owned by a private contractor under contract to transport children to and from public school. See, for example, February 20, 1987 letter to Mr. Martin Chauvin (copy enclosed). 2. Would Federal safety standards restrict a state from requiring safety belts on school buses? A state requirement that all school buses be equipped with safety belts regulates the same aspect of performance as the Federal standard for school bus occupant crash protection (FMVSS No. 222, School Bus Passenger Seating and Crash Protection) and would not be identical to that standard for large school buses (those with a gross vehicle weight rating (GVWR) over 10,000 pounds). FMVSS No. 222 requires school buses to provide passenger crash protection through a concept called 'compartmentalization.' Providing compartmentalization entails improving the interior of the school bus with protective seat backs, additional seat padding, and better seat spacing and performance. These interiors are intended to keep occupants in their seating area and protect them during a crash. FMVSS No. 222 requires the additional protection of safety belts at each passenger position in small school buses (10,000 pounds or less GVWR) because these buses experience greater force levels in a crash. A state requirement for safety belts on school buses would be identical to the level of performance required for small school buses, but would specify a different level of performance for large school buses. However, because the state requirement specifies a higher level of performance for large school buses than that required by FMVSS No. 222, Maine may require the installation of safety belts in school buses procured by the State or its political subdivisions, as long as the Federal requirements for compartmentalization are not compromised. 3. Could a school bus fleet modify the rear lighting configuration of their buses (8 light system) to reduce the potential for other vehicles rear-ending buses during poor visibility conditions, e.g., fog? ... The proposed change is to replace the white 8 inch back-up lights with 8 inch red sealed beam warning lights similar to the two at the upper level of the rear end of the bus. These would flash in an alternating criss-cross fashion when the bus is stopped loading or discharging students. The small white lights at the lowest level of the rear end of the bus would each be replaced with white, universal backup lights angled to also direct their beams at 45 degree angles out from the rear of the bus. The answer to your question is yes if the school district or its fleet contractor performs the modification itself. The National Traffic and Motor Vehicle Safety Act (the Safety Act, 15 U.S.C. 1381 et seq.) authorizes this agency to issue FMVSS applicable to new motor vehicles and new items of motor vehicle equipment. Section 108(a)(1)(A) of the Safety Act (15 U.S.C. 1397(a)(1)(A)) prohibits the sale for purposes other than resale of any new motor vehice or item of motor vehicle equipment unless it is in conformity with all applicable FMVSSs. After the first purchase of a vehicle in good faith for purposes other than resale, the only provision in Federal law that affects a vehicle's continuing compliance with an applicable safety standard is set forth in Section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)). That section provides that: No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle ... in compliance with an applicable Federal motor vehicle safety standard. This provision does not regulate in any manner how a vehicle owner can modify his or her vehicle. I note, however, that this agency encourages vehicle owners not to tamper with their vehicle's safety equipment if the modification would degrade the safety of the vehicle. In addition, it is possible that the modifications you describe could be made by one of the named commercial entities without violating the 'render inoperative' provision. The modification you describe affects two requirements of FMVSS No. 108, Lamps, reflective devices, and associated equipment. FMVSS No. 108 requires buses, including school buses, to have at least one backup light meeting the photometric and height requirements of SAE Standard J593c, February 1968. If the small white lights at the lowest level of the rear end of the bus comply with these requirements, the vehicle would continue to conform with this requirement. Section S5.1.4 of FMVSS No. 108 requires school buses to have a system of either four red or four red and four amber signal lamps which conform to SAE Standard J887, July, 1964. The modification you describe would add an additional two red signal lamps to the existing eight light system. Section S5.1.3 of FMVSS No. 108 states that '(n)o additional lamp, reflective device or other motor vehicle equipment shall be installed that impairs the effectiveness of lighting equipment required by this standard.' It is our opinion that the addition of two red signal lamps would not violate this provision. I hope this information is helpful.

TITLE: FMVSS INTERPRETATION

TEXT: This responds to your letter of July 3, 1979, asking several questions concerning the definition of "designated seating position" (49 CFR 571.3), as that term was recently amended (44 FR 23229, April 19, 1979).

In your first question, you ask for confirmation that any bench or split-bench seat with less than 50 inches of hip room may never be required to have three or more than three designated seating positions, notwithstanding the capability of accomodating a person at least as large as fifth percentile adult female. Your assumption is incorrect. As noted in the (Illegible Word) to the recent amendment, the 50-inch specification does not mean that some vehicle seats with less than 50 inches of hip room should not also have more than two designated seating positions, if the vehicle and seat design is such that three positions would likely be used (44 FR 23232). The specification is nerely the amount of space the agency will consider as conclusive evidence that there should be at least three designated seating positions. The 50-inch caveat was included in the definition to simplify determinations of proper seating capacity by both manufacturers and the agency.

Your second question involves technical aspects of the amended definition of "designated seating position". The definition specifies that "hip room" is to be measured in accordance with SAE J1100(a). That standard defines "hip room" as,

"the minimum dimension measured laterally between the trimmed surfaces on the 'x' plane through the (Illegible Word) front Vithin 1.0 in. (25mm) below and 3.0 in. (76mm) above the SqRP-front and 3.0 in. (76mm) force and aft of the SqRP-front." (Area A in your diagrams.)

Your question includes diagrams and asks whether various portions of vehicle seats or other components would be considered "trimmed surfaces" within SAE Standard J1100(a).

Specifically, you ask whether slightly soft surfaces such as arm rests, seat back contours or other raised portions of the seat cushion would be considered "trimmed surfaces", for purposes of determining the minimum hip room dimension. The answer to your question is yes. The agency would probably consider all of the surfaces illustrated in your letter "trimmed surfaces" and, strictly speaking, within the meaning of the SAE procedure. This interpretation must be qualified, however. The procedure specifies that "hip room" is the minimum dimension "between trimmed surfaces". If a particular bench seat has distinct sections, the total dimension must be determined by adding the minimum dimensions of each section. For example, your Figure 5 illustrates a bench seat that includes a slightly raised center surface on the tunnel (in the center of the seat over the driveshaft). The lowest portion of Area A as defined in SAE J1100(a) would strike the side of this elevated center section, even though the top portion of Area A would be above the elevation. In such case, there would be three distinct portions of the seat (the driver's seat, the passenger seat, and the center seat position) that should be measured separately and then added together to get the total dimension. Otherwise, only the portion of the seat on the driver's side of the center elevation would be measured under the strict wording of the SAE procedure--an absurd result.

Regarding these questions about the measurement procedure, I must make several candid remarks. The agency will not allow manufacturers to avoid the obvious intent of the definition of "designated seating position" by finding loopholes in the measurement procedure. Further, as noted above, even if the hip room as measured in accordance with SAE J1100(a) is less than 50 inches, a manufacturer may still be required to designate three seating positions. If the measured dimension is less than 50 inches only because of slight elevations or contours on the outside seat cushion, a manufacturer must designate at least three positions if these elevation or contours are not real impediments to three persons occupying the seat.

Determinations of designated seating capacity under the amended definition should not cause manufacturers any real problems. If a manufacturer truly only intends to market a particular bench or split-bench seat for two occupants, he can and should make this obvious by the seat design, regardless of whether the total seat dimension is more than 50 inches or less than 50 inches. One simple way to do this is to install a permanent arm rest or console in the center portion of the seat.

I hope this response has clarified our position and will alleviate any problems you might have in making future determinations of proper designated seating capacity.

Dear Mr. Hunter:

During my May 4th visit to your office, I requested your interpretation concerning the measurement procedure of the "Hip Room" with regard to SAE J 1100a, which was adopted in the 49 CFR Part 571, "Designated Seating Position". The final rule was issued in the April 19, 1979 Federal Register, Vol. 44, No. 77.

At that time, you suggested that I submit my questions, along with a letter, to your office for response.

I would, therefore, like to take this time to submit my questions to you and ask for your interpretation.

Thank you for your fine cooperation with regard to this particular matter. We look forward to hearing your interpretations in the near future.

Q-1 The "X" plane through the SgRP

SAE J 1100a states the following as the definitions of the Three-Dimensional Reference System and the Hip-room:

ZERO "Y" PLANE - (Centerline body zero plane) is a vertical plane which passes through the longitudinal centerline of the vehicle.

ZERO "X" PLANE - Vertical body zero plane is a plane normal to the "Y" plane.

ZERO "Z" PLANE - Horizontal body zero plane is a plane normal to the "X" and "Y" planes.

W5-HIP ROOM-FRONT - The minimum dimension measured laterally between the trimmed surfaces on the "X" plane through the SgRP-front within 1.0 in (25 mm) below and 3.0 in (76 mm) above the SgRP-front and 3.0 in (76 mm) fore and aft of the SgRP-front.

W6-HIP ROOM-SECOND - Measured in the same matter as W5

The above-mentioned definitions are identical to those in SAE J 182a as shown in Fig. 1.

It is my understanding that the "X" plane through the SgRP (I think we should call this "X" plane the "Y-Z" plane through the SgRP, mathematically speaking) in W5 or W6 of SAE J 1100a is the one as shown in Fig. 2. Is my understanding correct?

Q-2 The measurement procedure of "Hip-room

Assuming that your answer to Q-1 is "yes", it would then be my understanding that there can be two (2) different ways of interpreting the measurement of W5 (or W6) as shown below.

(a) The case of emphasizing "the "X" plane through the SgRP"

In this case, W5 will be defined as follows, and the words of "and 3.0 in (76mm) fore and aft of the SgRP-front"will not be significant as shown in Fig. 3.

W5-HIP-ROOM - The minimum dimension measured laterally between the trimmed surfaces on the "X" plane through the SgRP-front within 1.0 in (25mm) below and 3.0 in (76mm) above the SgRP-front.

(b) The case of emphasizing "within 1.0 in . . . . aft of the SgRP-front"

In this case, W5 will be defined as follows, and the words of "through the SgRP-front" will not be significant as shown in Fig. 4.

W5-HIP-ROOM - The minimum dimension measured laterally between the trimmed surfaces on the "X" plane within 1.0 in (25mm) below and 3.0 in (76mm) above the SgRP-front and 3.0 in (76mm) fore and aft of the SgRP-front.

Which is correct, (a) or (b)?

TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of April 18, 1985, concerning the applicability of our safety standards to a passenger van you are designing. Specifically, you asked whether you can install a stationary, side-facing passenger seat with lap safety belts. As discussed below, you can use such a seat with a lap safety belt, but its use would be affected by Federal Motor Vehicle Safety Standard Nos. 207, Seating Systems, 208, Occupant Crash Protection, 209, Seat Belt Assemblies, and 210, Seat Belt Assembly Anchorages. A copy of each of those standards is enclosed.

Standard No. 207 specifies performance requirements for seats, their attachment assemblies, and their installation, to minimize the possibility of seat failure resulting from crash forces. This standard is applicable to seats installed in vehicles including vans, but section 4.2 of Standard No. 207 excludes side-facing seats from the general seat strength requirements of the standard. However, there are other requirements in the standard which may apply to side-facing seats. For example, paragraph S4.3 requires a restraining device if the seat has a hinged or folding seat or seat back.

Standard No. 208 sets requirements for the installation of safety belts in motor vehicles. You stated that the vehicle you are designing is a passenger van that carries under 10 passengers. If your vehicle carries a total of 10 persons (9 passengers and a driver) it would be considered either a multipurpose passenger vehicle (MPV), if it is manufactured on a truck chassis or has special features for occasional off-road use, or a passenger car.

If your vehicle is a passenger car, section 4.1.2.3(c) of the standard provides that each designated seating position for rear passengers can have a Type 1 (lap) or Type 2 (lap/shoulder safety belt) that conforms with Standard 209 and the adjustment and latch mechanism requirements of S7.1 and S7.2 of Standard No. 208. If your vehicle is a MPV, then S4.2.2, for MPV's with a GVWR greater than 10,000 pounds or less, or S4.3, for MPV's with a GVWR greater than 10,000 pounds, provides that each designated seating position for rear passengers can have a Type 1 or Type 2 safety belt that conforms to Standard No. 209.

Standard No. 210 sets performance requirements for safety belts anchorages in passenger cars, MPV's, trucks, and buses. The standard exempts side-facing seats from its strength requirements specified in S4.2, but all other requirements of the standard apply to side-facing seats. We strongly recommend that belt anchorages for side-facing seats be of at least equivalent strength to the anchorages for forward and rearward facing seats, since the strength specifications are only minimum performance requirements.

Dear Sir:

This letter is a request for a ruling concerning a safety standard as applicable to passenger van seating. Specifically, I need to know if putting a stationary side facing seat, with lap seat belts is legal and acceptable.

This side facing seat would be equipped with lap seat belts if necessary. It would be located at the rear of the vehicle, behind the drivers seat.

The vehicles in question are for under 10 passengers, and are of 15', 17', and 20' lengths.

We are in the middle of a design project on this and your prompt attention to this matter would be greatly appreciated. Please call 316/ 942-0905 if you have any questions. Thank you.

Mr. William Smith in your engineering dept. requested that I consult you for a permanent ruling. His interpretation of the rules would allow the use of this side facing seat.

Dear Mr. Ruegg: This responds to your letter of March 27, 1993, to Mr Eisner of the General Counsel's Office of the Department of Transportation (DOT). You intend to import 'car parts' into the United States, and would like to know 'the legal definition of a vehicle that comes within the scope of D.O.T. regulations'. You assume that 'a part such as fender or other body parts do not.' You have asked this question because some individual parts may arrive as part of assemblies, such as 'chassis and body assembly or perhaps chassis and body plus front & rear axle transmissions.' The National Highway Traffic Safety Administration (NHTSA) is the component of DOT that regulates the importation of motor vehicles and motor vehicle equipment, principally through the National Traffic and Motor Vehicle Safety Act and regulations issued under its authority such as the Federal motor vehicle safety standards (FMVSS). Each part or component of a motor vehicle is motor vehicle equipment subject to NHTSA's jurisdiction. The Act requires that motor vehicle equipment, whether new or used, meet all applicable FMVSS in order to be imported into the U.S. Some of the FMVSS apply to items of motor vehicle equipment. Thus, whether shipped separately or as part of an assembly, equipment such as brake hoses, tires, brake fluid, rims for vehicles other than passenger cars, glazing, seat belt assemblies, and wheel covers must comply in order to be admitted into this country. As your question implies, there is a point at which an assemblage of motor vehicle equipment becomes a 'motor vehicle'. An assemblage becomes an 'incomplete motor vehicle' subject to regulation as a vehicle manufactured in two or more stages (49 CFR Part 568) when it consists, at a minimum, of 'frame and chassis structure, power train, steering system, suspension system, and braking system, to the extent those systems are to be part of the completed vehicle, that requires further manufacturing operations . . . to become a completed vehicle (Sec. 568.3).' As the intention is to import the vehicle without the electric power train, the assemblage you contemplate is not a 'motor vehicle' and remains an assemblage of motor vehicle equipment whose individual components, as noted in the preceding paragraph, are required to comply with the applicable FMVSS. Your letter informs us that ' t hese parts and partial assembly's (sic) would be sold as kits for conversion to electric vehicle.' When the power train is added, the person completing the manufacture of the vehicle is considered to be its manufacturer, required to certify compliance with all applicable FMVSS. If you have any further questions, we would be pleased to answer them. Sincerely, John Womack Acting Chief Counsel;

Dear Mr. Lawler: This responds to your recent letter asking whether paragraph S4.2.2 o Safety Standard No. 208, *Occupant Crash Protection*, is applicable to school buses with a GVWR of 10,000 pounds or less.; The answer to your question is yes. Safety Standard No. 222 specifie in paragraph S5(b) that all seats, other than the driver's seat, in school buses with a GVWR of 10,000 or less shall meet the requirements of Safety Standard No. 208 as they apply to multipurpose passenger vehicles. The requirements for multipurpose passenger vehicles in Standard No. 208 are found in paragraph S4.2.2 for vehicles manufactured on or after January 1, 1976. There is no exception in S4.2.2 which allows school buses to comply with S4.2.1.2 of Standard No. 208.; School buses are not specifically mentioned in paragraph S4.2.2 o Standard 208, because that standard includes separate requirements for buses (including school buses) in paragraph S4.4. Under the general bus requirements of Standard 208, only the driver's position must be equipped with a seat belt. These requirements are supplemented by the more specific provision in Standard No. 222 which, as noted earlier, requires small school buses to meet the requirements of Standard 208 as they apply to multipurpose passenger vehicles.; I hope this has clarified your understanding of the requirements o these two standards. Please contact Hugh Oates of my staff if you have any additional questions (202-426-2992).; Sincerely, Frank Berndt, Chief Counsel
