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.

Dear Mr. Cucheran:

This is in reply to your letter of November 30, 1984, to Mr. Vinson of this office asking for an interpretation of Motor Vehicle Safety Standard No. 108 Lamps, Reflective Devices, and Associated Equipment.

Figure 10 of Standard No. 108 establishes the minimum design photometrics for center high mounted stoplamps. The test procedure for this particular part of Standard No. 108 which is specified in SAE J186a, stipulates that the "lamp axis shall be taken as the horizontal line through the light source." However, I believe that you have misinterpreted the light cone that is involved. The pertinent light cone in this case has its vertex at the photometer and a cross section at the plane of the lamp which encompasses the lens areas. From Drawing A that you have provided, it appears that your rail would interfere with this light cone.

In order to determine if your rack interferes with the photometric requirements, the vehicle must be tested with the rack in position as installed on the vehicle. As the agency has noted before, the photometric requirements do not specify that the entire lens must be visible from each 5 degree down test point. Instead, they specify the intensity of light that must be visible from those points. Therefore, the requirement can be met with a lamp whose lens is partially obscured by a portion of the vehicle when viewed from some of the test points.

We hope that this interpretation is helpful to you.

Sincerely, Frank Berndt Chief Counsel November 30, 1984 Mr. Taylor Vinson U. S. Department of Transportation National Highway Traffic Safety Administration 400 Seventh Street S.W. Washington, D.C. 20590 Subject: Center Mounted Stop Light

Dear Mr. Vinson:

As you are aware, the cross rail on our deck mounted luggage racks supplied to O.E. automotive manufacturers infringes the 50 down cone requirement of Standard Number 108. This infringement will cause our products to be deleted from 1986 model vehicles equipped with center mounted stop lights with 50 cones that do not clear the rear rails.

Because we were not successful in getting a variance to allow infringement of the 5o cone on vehicles equipped with deck mounted luggage racks, our company will lose approximately 3 million dollars worth of business per year starting next summer, plus the loss of many jobs in an area already hit with some of the highest unemployment figures in the country. We are doing everything possible to adapt our products on new vehicles to save as many of our employees jobs as possible.

One thing that might make a difference on some potential 1986 business, is a clear definition of where the horizontal line, to establish the 5o cone, is taken from in the side view. I have enclosed two illustrations to clarify my request.

Illustration A shows the relationship of the light cone taken from the center of the lens, to a cross rail section. As you will notice, the light cone clears the bar.

Illustration B shows the relationship of the light cone taken from the bottom of the lens, to a cross rail section. As you will notice, the light cone is infringed by the cross rail. Mr. T. Vinson U.S. Department of Transportation November 30, 1984 Page Two

Several of our customers have taken for granted that the intent of the Standard is to establish the light path from the bottom of the lens. As you can see from our illustrations, the location of this point can mean approval or rejection of our products in cases such as this.

Your interpretation of our request, at your earliest date, would be greatly appreciated.

Very truly yours, John S. Cucheran Vice President Design and Engineering cc: Mr. Barry Felrice/Associate Administrator for Rulemaking Mr. Jack Bott/President-JAC Products Inc.

This is in further response to your December 12, 1984 letter to the National Highway Traffic Safety Administration (NHTSA) concerning our definition of a school bus. Your specific question asked, "Are vehicles which are built to carry ten school aged passengers or less, and which are used for school or related functions, considered by NHTSA to be school buses or multipurpose passenger vehicles?" As explained below, a vehicle carrying 11 or more persons (i.e., 10 children and a driver) to and from school or related events would be considered a school bus. A vehicle carrying 10 or less persons would be a multipurpose passenger vehicle.

Under the definitions section of our Federal Motor Vehicle Safety Standards (49 CFR Part 571.3), vehicles carrying 11 or more persons which are sold for purposes that include carrying students to and from school or related events are "school buses." Under our regulations, a vehicle which is designed to carry less than 11 persons would considered a multipurpose passenger vehicle. Such a vehicle would be certified as complying with the safety standards applicable to multipurpose passenger vehicles.

Ms. Deirdre Hom of my staff informed your associate, Mr. Joe Clark, of the above in a telephone call on December 14, 1984. This letter confirms the information given to Mr. Clark in that conversation.

If you have any further questions, do not hesitate to contact my office.

Sincerely,

Frank Berndt Chief Counsel December 12, 1984

Mr. Frank Berndt, Chief Counsel National Highway Traffic Safety Adm. 407 Street S.W. , Room 5219 Washington, DC 20590

Dear Sir:

We, as a manufacturer school bus bodies, have for some time now been operating with the understanding that vehicles built to transport ten (10) passengers or less came under the vehicle classification designated as a multi-purpose vehicle. For this reason, we have refrained from building school bus bodies with capacities of ten passengers or less. (Please see the attached bulletin we published on this matter.)

It is recently been brought to our attention that this interpretation, which we are recently following, is not a shared practice by every manufacturer. Although we do not have actual verification of the fact, we understand NHTSA has advised some bus body manufacturers that the multi-purpose vehicle definition does not serve the intent of the public law, specifically as it relates to the transportation of ten school aged passengers or less.

We, therefore, wish to have clarification of this matter and specially to the question: Are vehicles which are built to carry ten school aged passengers or less, and which are used for school or related functions, considered by NHTSA to be school buses or multi-purpose vehicles?

We have a bid pending for several units and would appreciate your telex response by Friday, December 14, 1984. I am afraid we will lose this bid unless we can respond positively in the same manner is our competitors have responded.

Sincerely,

Jerry D. Williams Senior Vice President Marketing

SUBJECT: Minimum Capacity Ratings for School Use Vanguard and Minuteman Model Bus Bodies

In order to certify a Vanguard or a Minuteman model bus body as a school bus, we must observe the federal minimum passenger capacity rating which is now set at ten (10) passengers. This minimum passenger rating does not include the driver. In the case of a lift-equipped bus, the passenger rating would translate to two (2) wheelchair passengers and eight (8) passengers seated in the fixed seating area.

For your information, if a Vanguard or Minuteman order is requested with a rating less than ten (10) passengers we must certify the bus to what is know as a multi-purpose vehicle standard. To meet this standard, other federal standards come into effect which are very stringent and extremely expensive to comply with. For this reason, we request your cooperation in always observing the minimum passenger capacity criteria of ten (10) passengers.

Mr. Verne L. Freeland P.O. Box 693652 Miami, FL 33269

This responds to your letter to Mr. Radovich of the Rulemaking division of this agency, requesting an interpretation of the requirements of Standard No. 213, Child restraint systems (49 CFR S571.213). Specifically, you stated that you had developed a child restraint system which was built into the vehicle seat, and asked how to proceed to have this child restraint certified as complying with Standard No. 213. As currently written, Standard No. 213 does not accommodate your type of restraint.

A manufacturer of a child restraint system is required to certify that each child restraint system manufactured by it complies with all of the requirements of Standard No. 213, and adding a statement to that effect to the label required by section S5.5 of the Standard. This certification need not be based on actual test results; NHTSA only requires that the certification be made with the exercise of due care on the part of the manufacturer. It is up to the individual manufacturer to determine what test results, engineering analysis, or other data would be sufficient to enable it to meet the due care requirement in certifying that its child restraints comply with the standard. Certainly, we would recommend that a manufacturer marketing a new child restraint design test that restraint in accordance with the test procedures specified in the standard.

As you will see from the enclosed copy of Standard No. 213, Section S5.3.1 of the standard requires each child restraint system to be capable of being restrained by a type 1 seat belt system. In addition, the test procedures in section S6 specify that the child restraint is to be tested by attaching it to a standard vehicle seat solely by the vehicle seat's lap belts. Your design, which incorporates the restraint into a vehicle seat, could not be attached to a standard vehicle seat by means of lap belts.

Standard No. 213 would have to be amended in order for you to be able to certify that your child restraint satisfies all the requirements of that standard. 49 CFR Part 552, Petitions for Rulemaking, Defect, and Noncompliance Orders (copy enclosed) gives interested persons the right to petition this agency for amendments a safety standard, and sets forth the required contents of the petition, the address to which it should be sent, and the procedures which will be followed by the agency in evaluating the petition. If you wish, you may file such a petition. Should such a petition be granted, this agency would follow its normal rulemaking procedures to amend Standard No. 213.

If you have some further questions or need further information on this subject, please contact Mr. Steve Kratzke of my staff at this address or by telephone at (202) 426-2992.

Val Radovich, Safety Standards Engineer, National Highway Traffic Safety Administration, 400 7th Street, S.W., Room 5316 NRM 12, Washington, D.C., 20590

Re: Obtaining certification of "Built-In Childs Safety Seat" to U.S. Motor Vehicle Safety Standard Number 213-80 - Child Seating Systems

Dear Mr. Radovich,

I am the inventor of a built-in childs safety seat as described and depicted in the attached copy of my pending application for U.S. Letters Patent as/also the attached illustrative pictures of miniature model of same.

In April, 1984, I submitted a copy of the patent application and pictures, together with a sales pitch, entitled 'comment' (copy attached) to each of the 19 directors of Chrysler corporation in hopes of having Chrysler manufacture and incorporate the depicted child's safety seat in their vehicles.

On May 8th 1984, as a result of the submission of such material to Chrysler, I received, signed and delivered to Chrysler a 'Suggestion Agreement' as a prerequisite which, I believed, would expedite the consideration and implementation of the invention by Chrysler. (copy attached).

On May 29, 1984, I was advised by Chrysler that the built-in childs safety seat must be certified by NHTSA to meet the requirements of U.S. Motor Vehicle Standard No. 213-80 - Child Seating Systems, before the seat could be evaluated by Chrysler. This May 29th letter from Chrysler further advised me to obtain information as to such certification by contacting NHTSA at 400 7th Street, S.W., Washington, D.C., attention: Secretary Dole. (a copy of such letter is attached).

On June 4, 1984, I sent a letter to NHTSA at the address and to the attention of Secretary Dole, as advised by the letter from Chrysler. (copy of June 4th letter attached).

On July 3, 1984, having received no response to my letter of June 4th, I began telephoning to seek the requested information, commencing with first telephone call to Secretary Dole's offices, which referred me to another telephone number, which referred me to another telephone number, etc., etc., etc., which finally resulted in my being advised that you (or a member of your staff) would ultimately respond to my June 4th letter when the same had finally filtered down through the chain of command from Secretary Dole's office. (a procedure which was estimated as a 'month or two').

In view of the foregoing information, and seeking to expedite the matter, I telephoned your office and was advised to send a new letter directly to you. During such telephone conversation I attempted to describe my invention in order to secure some telephonic information as to the procedure, criteria, and time element involved in obtaining the desired certification and was advised that since my proposed seat is bolted to the regular auto seat (as a built-in integral part thereof) it did not have the required 'tether belting' necessary to meet the specifications of Standard 213-80 and hence, would probably require petition for variance or for an exemption from such requirement of the act.

Now then, Mr. Radovich, having given you all of the background information, with supporting documents, I ask for your assistance in obtaining the requested certification as expeditiously as is possible including but not limited to:

(a) Advising me as to the procedure or procedures necessary to effect certification of the depicted built-in childs safety seat.

(b) Advising me as to the necessity and, if so, the procedure for obtaining variance and/or exemption from the 'tether belt' requirement of 213-80.

(c) Advising me as to whether or not I must construct and furnish you with a full scale working model of the depicted built-in childs safety seat and, if so, where and when?

(e) Advising me as to the anticipated costs and expenses involved in obtaining certification, and

(f) Such other and further advice as you may be so kind as to suggest in order to obtain the requested certification as expeditiously as is possible.

In regard to the ultimate certification, I understand that the present certification requires that child seat safety equipment meet safety standards of a thirty (30) mile per hour impact test. It is my belief that the depicted built-in childs safety seat will meet much higher safety standards of 55 miles per hour impact, and higher. This, coupled with the elimination of injuries caused by improperly attached equipment, etc., (as suggested in the patent application and comments) may well give rise to further decreasing injuries to children in vehicles and, consequently, I am anxious to have the built-in childs safety seat tested to its maximum safety certification instead of the normal and minimal 30 miles per hour standards.

I apologize for the length of this letter but I sincerely believe that the depicted seat constitutes such a substantial improvement of the existing childs safety seats now on the market as to warrant consideration of getting it certified and on the market as soon as humanly possible.

Yours very truly,

Verne L. Freeland

This responds to your letter of November 8, 1984, asking numerous questions concerning Standards No. 208, 209 and 210. The answer to your questions, numbered as presented in the attachment to your letter, are as follows:

1.) S.7.4.4 of Standard No. 208 sets requirements concerning access to the latchplate on the outboard side of a seat. The purpose of the requirement is to make safety belts more convenient to operate by requiring the latchplate to be accessible. You asked, in effect, whether the requirements of S7.4.4 also applies to an inboard mounted buckle located between the seat and a console. The answer is no. An inboard mounted buckle, however, must comply with the requirements of S7.4.6.

2.) You asked what is the meaning of the terms "comfort clip and window-shade" in section 7.4.2 of Standard No. 208. The terms refer to elements of a safety belt system which are used to relieve tension in the torso portion of a Type 2 lap-shoulder belt. A comfort clip is a device which attaches to the belt and can be positioned by an occupant to introduce and maintain slack in the belt system by physically preventing the belt slack from being taken up by the belt's retractor. The term window-shade refers to a type of device in a safety belt retractor which allows an occupant to introduce and maintain slack in the belt once it has been adjusted around the occupant.

3.) You asked if it is considered, "Action", if the driver hangs the webbing of an automatic belt on a manual convenience hook. An automatic belt must provide protection by means that require no action by the vehicle occupants. Manual vehicle convenience hooks used with an automatic belt system must comply with S 7.4.1 of the Standard, which requires a convenience hook to automatically release under specified conditions.

4.) You asked if it is mandatory to use 7/16-20 UNF 2A or 1/2-13 UNC-2A bolts for automatic belt mounting hardware. The answer is no. Automatic belts meeting the frontal crash protection requirements of Standard No. 208 are not required to meet all of the requirements of Standard No. 209. The enclosed interpretation letter of August 7, 1981, to Volkswagen more fully explains the application of Standard No. 209 to automatic belts.

5.) You asked if the retractor of a rear lap belt is a 2 point mounting type, are both points considered to be anchorage points? You also asked if both points must be within the range specified in S 4.3.1.1 of Standard No. 210.

Standard No. 210 defines an anchorage as "provision for transferring seat belt assembly loads to the vehicle structure." If by a two point mounting you mean a retractor that has two means for transferring the belt loads to the vehicle structures, then both points are anchorages and must conform to Standard No. 210. The range specified in S4.3.1.1. is measured from the seating reference point to the point of contact of the webbing with its attachment hardware. It does not require the anchorage points to be within that range.

6.) Finally, you asked what is the definition of the term "most upright position" used in S 4.3.2.1 of Standard No. 210. In referring to the "most upright position" of the seat back, the agency means the seat back adjustment position which most closely approximates a vertical position.

I hope this information is of assistance to you.

Sincerely,

Frank Berndt Chief Counsel

Thomas Built Buses, L.P.
P.O. Box 2450
1408 Courtesy Road
High Point, NC 27261

Dear Mr. Mitchell:

This is a response to your letter asking whether it is permissible to install only two seat belts on a 39-inch bench-seat in a school bus with a gross vehicle weight rating (GVWR) of 10,000 pounds or less (small school bus). I apologize for the delay in this response. The answer is no.

You stated that Thomas Built Buses (Thomas) would like to accommodate certain customers who wish to have two designated seating positions on each 39-inch bench-seat installed in a small school bus "for passenger comfort reasons." Your letter sets forth a suggested rationale as to why Thomas believes such a configuration would be permissible in small school buses. First, you argued that a May 11, 1978 interpretation of Standard 217, Bus Window Retention and Release, states that Federal motor vehicle safety regulations do not prohibit having only two-passenger seating positions on a 39-inch bench-seat in a bus designed for adult transportation. In these circumstances, we said, a manufacturer has some discretion to decide the number of designated seating positions in its vehicles, but must make a good faith determination of the vehicle's passenger capacity to discourage vehicle overloading.

You reason that because the term "designated seating position" is in the Definitions section of the Federal safety standards (49 CFR 571.3), the definition applies to all safety standards. You apparently conclude that our earlier interpretation of Standard 217 and the definition of "designated seating position" in 571.3 permit a manufacturer to make a good faith determination respecting the number of seating positions on a school bus. Based on this conclusion, you posited two situations in which this reasoning might be applied.

Situation 1 was described as follows in your letter:

Thomas Built Buses interprets (the May, 1978, interpretation) to be applicable for a school bus sold to carry only high school students. We consider the use of two seat belts on a 39 inch seat to be reasonable and justified due to passenger size making three passengers on one 39" seat impossible. We would honor a purchaser's request to equip these 39" seats with two belts each. Is this interpretation correct?

This interpretation is incorrect for several reasons. First, the earlier interpretation did not apply to school buses; by its own terms, it is clearly limited to buses other than school buses. Second, there is not a separate set of standards that specify differing requirements for school buses designed to carry high school students. In determining whether school bus standards apply to a vehicle designed to carry 11 or more persons, the proper inquiry is whether the bus is sold to carry "primary, preprimary, or secondary school students" to or from school or school-related events. Any vehicle that meets this definition of the term "school bus" must comply with all applicable school bus standards, regardless of whether it is designed to carry small children to kindergarten or teenagers to high school.

Third, the definition of "designated seating position" and our interpretations of that term, are not relevant in determining whether a school bus bench-seat in a small school bus complies with the requirements of Standard 222. Paragraph S4.1 of Standard 222 sets out a specific procedure for calculating the number of seating positions in a bench seat. That paragraph explains that the number of seating positions on a bench seat in school buses is calculated by (1) measuring the width of the bench seat in inches, (2) dividing by 15, and (3) rounding to the nearest whole number. The value which results from this calculation (expressed by the term "W") is the basis for determining whether the seat complies with the requirements of Standard 222.

For a 39-inch bench-seat, the procedure in S4.1 shows that this seat has three seating positions. Paragraph S5(b) of Standard 222 therefore requires that this bench-seat have three seat belt assemblies installed. Therefore, if your company were to install only two seat belt assemblies on a 39-inch wide bench-seat in a small school bus, you could not certify that the vehicle complies with Standard 222.

For these same reasons, your interpretation set forth in your "Situation 2" is also incorrect. Even if a customer specifically asks that only two seat belt assemblies be installed on 39-inch bench seats, Standard 222 requires your company to equip these seats with three seat belt assemblies.

I hope you find this information helpful.

Sincerely,

Erika Z. Jones Chief Counsel

Dear Mr. Mounteer:

This responds to your letter on behalf of your client, Heritage Motors, that asked whether Heritage, given the nature of its manufacturing process, must assign its own Vehicle Identification Numbers (VINs). I apologize for the delay in this response. As discussed below, since Heritage considers the vehicles it manufactures to be: (l) "new" vehicles and (2) manufactured in one stage, it must assign its own VINs to the cars. I note that this letter addresses the vehicles Heritage assembles and not the "kits" which Heritage also sells.

According to your letter, Heritage Motors makes replica Mercedes 500K passenger cars, using 1970-1981 Chevrolet Camaros as donor cars. An information brochure accompanying your letter describes the parts that are removed from the Camaros and then reused in the Mercedes replica. Since Heritage uses a new body, engine, transmission, and many other new or remanufactured parts, you have considered the completed vehicle to be a "new" motor vehicle. Moreover, Heritage manufactures the vehicles in one stage.

Under section S4.l of Federal Motor Vehicle Safety Standard No. ll5, Vehicle Identification Number--Basic Requirements, each vehicle manufactured in one stage must have a VIN that is assigned by the manufacturer. Heritage must therefore assign its own VIN numbers to the cars it manufactures.

I hope this information is helpful. If you have any additional questions, please feel free to contact Ms. Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992.

Dear Mr. Bernard:

This letter responds to your inquiry of August 21, 1987, where you asked for this agency's opinion on whether Federal motor vehicle safety standard 115 (49 CFR 571.115) requires a manufacturer's chrome script name on the trunk of vehicles it manufactures. It does not.

Standard 115, Vehicle Identification Number- Basic Requirements, directs a vehicle manufacturer to place a discrete vehicle identification number (VIN) on each vehicle it manufactures. Under paragraph S4.5, the VIN for any motor vehicle must appear indelibly on a part of the vehicle other than the glazing, that is not designed to be removed except for repair. Paragraph S4.6 states that the VIN for passenger cars must appear inside the passenger compartment. Title 49 CFR Part 565, VIN-Content Requirements, states that among other things, the VIN's first three characters must identify the vehicle manufacturer. However, neither Standard 115 nor Part 565 require a manufacturer's name plate to appear on the vehicle.

I hope you find this information helpful.

Sincerely,

Erika Z. Jones Chief Counsel

Dear Mr. Malinowski:

This responds to your letter on behalf of Mr. Leo McCallum, asking whether any Federal Motor Vehicle Safety Standard applies to his invention, a tie rod "safety bracket." You stated that the product would typically be installed by a vehicle owner to reduce tie rod end wear. As explained below, while no Federal safety standard directly applies to your client's product, he may nevertheless have certain responsibilities under this agency's regulations.

As way of background information, the National Traffic and Motor Vehicle Safety Act of 1966, as amended (the "Safety Act") authorizes the National Highway Traffic Safety Administration (NHTSA) to issue safety standards applicable to motor vehicles and items of motor vehicle equipment. The Safety Act also requires that these safety standards establish minimum levels of performance for vehicles or equipment. Once the necessary performance level has been established, vehicle or equipment manufacturers are free to choose any means they wish to achieve the required level of performance. In other words, the safety standards do not require the use of any particular manufacturer's product or particular materials; the standards permit the use of any manufacturer's product that achieves the necessary performance level. Section 114 of the Safety Act (15 U.S.C. 1403) requires manufacturers to certify that each of its vehicles or items of motor vehicle equipment complies with all applicable safety standards. NHTSA does not approve, endorse, or certify any motor vehicle or item of motor vehicle equipment.

NHTSA has no safety standard directly about tie rods or safety brackets used with tie rods.

As for installation of your client's device on vehicles in the aftermarket, such installations may be limited by section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)). That section prohibits any manufacturer, distributor, dealer, or motor vehicle repair business from knowingly rendering inoperative any device or element of design installed on or in a motor vehicle in compliance with an applicable safety standard. If installation of your client's product resulted in a vehicle no longer complying with a safety standard, a manufacturer, distributor, dealer, or repair business that installed the product would have rendered inoperative a device or element of design installed on the vehicle in compliance with a standard. To avoid a "rendering operative" violation, your client should examine his product to determine if installing his product would result in the vehicle no longer complying with a standard's requirements.

Section 109 of the Safety Act (15 U.S.C. 1398) specifies a civil penalty of up to $1,000 for each violation of the "render inoperative" provision.

Please note that the Safety Act does not establish any limitations on an individual vehicle owner's ability to alter his or her own vehicle. Under Federal law, individual owners can install any device they want on their own vehicles, regardless of whether that device renders inoperative the vehicle's compliance with a safety standard.

Other statutory provisions in the Safety Act could affect your client's product. Manufacturers of motor vehicle equipment such as the "tire rod safety bracket" are subject to the requirements in sections 151-159 of the Safety Act (15 U.S.C. 1411-1419) on the recall and remedy of products with defects related to motor vehicle safety. The Safety Act specifies that if either the manufacturer or this agency determines that a safety-related defect exists in your client's product, your client as the manufacturer must notify purchasers of the safety-related defect and must either:

(1) repair the part so that the defect is removed; or

(2) replace the part with an identical or reasonably equivalent part which does not have a defect.

Whichever of these options is chosen, the manufacturer must bear the full expense and cannot charge the owner for the remedy if the equipment was purchased less than eight years before the notification campaign.

I hope this information is helpful. If you have any further questions, please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992.

General Manager
Phoenix Transit System

Dear Mr. Hocken:

This is in reply to your letter of December l6, l987 to Mr. Vinson of this office requesting an interpretation of Motor Vehicle Safety Standard No. l08. You have received a "Service Information Safety Related letter" from Flxible Corporation stating that deceleration warning lights installed on your buses do not comply with Standard No. l08. You have also asked how you may file for "Special Exception" if your buses are not in compliance.

This will confirm that Flxible Corporation, pursuant to applicable Federal regulations, has determined that certain buses produced by it, including the 67 units furnished Phoenix, do not comply with Standard No. l08, and has initiated a notification and remedy campaign (Campaign 87V-089). The basis of this determination was the manufacturer's conclusion that flashing amber deceleration warning lamps could create confusion when activated simultaneously with the red steady burning stop lamps. The company has advised you of the corrective action to be taken, that is, to remove the deceleration flasher. Although the agency encourages owners of campaigned vehicles to remedy noncompliances, the decision whether to do so rests with the vehicle owner. There is no Federal requirement that an owner correct a noncompliance that exists in his vehicle, and no penalty for his failure to do so. Thus, no "Special Exception" is either needed or available for an owner who wishes to continue operating a vehicle in a noncompliant state.

We are interested in your comment that you experienced a 44 percent reduction in accidents in l985, the first full year that the system was installed on all your buses, compared with l984. This report compares favorably with the accident reduction experienced in our test fleets of passenger cars equipped with center highmounted stop lamps, which was the basis for eventual adoption of that requirement. The agency is engaged in research pertaining to the conspicuity of large vehicles, and would find it helpful to have a copy of the data upon which you based your comment. It should be sent to Michael Finkelstein, Associate Administrator for Research and Development, NHTSA, 400 Seventh Street, S.W., Washington, D.C. 20590. We appreciate your interest in safety.

Sincerely,

Erika Z. Jones Chief Counsel

Dear Ms. Otjen:

This responds to your request for an opinion whether Oregon's specifications for Hazardous Material Emergency Response Vehicles are consistent with the Federal Motor Vehicle Safety Standards. Based on the information provided in your letter and telephone conversations with Steve Kratzke of this office, there is no inconsistency betweens Oregon's specifications and the Federal safety standards.

The Emergency Response Vehicles in question have a Gross Vehicle Weight Rating (GVWR) of more than 10,000 pounds. Oregon's specifications call for the vehicle to include a manual safety belt at each seating position. One of the parties bidding on the contract for these vehicles suggested that these specifications were inadequate to comply with the requirements of the Federal safety standards, because, according to the bidder, the Federal standards require a crash test to measure the occupant protection afforded in these vehicles. The bidder's assertion is inaccurate.

The occupant protection requirements applicable to these Emergency Response Vehicles are set forth in S4.3.2 of Standard No. 208, Occupant Crash Protection (49 CFR 571.208). That section requires that trucks and multipurpose passenger vehicles with a GVWR in excess of 10,000 pounds provide occupant protection at every designated seating position, but gives manufacturers two alternative means of providing the necessary protection.

The first option for manufacturers of these vehicles, as set forth in S4.3.2.1, is to provide automatic crash protection (e.g., air bags or automatic safety belts) for occupants. If this option were chosen, the vehicle would be subject to crash testing by NHTSA during its compliance evaluations. To date, no manufacturer of heavy vehicles has ever chosen this option. Instead, they have chosen the second option.

The second option, as set forth in S4.3.2.2, is to provide manual safety belts at every designated seating position. No vehicle crash testing is conducted under this option. Instead, compliance evaluations are based on a series of static tests of the safety belt assembly and the anchorage for that assembly. Accordingly, there is nothing in the Oregon specifications for these Emergency Response Vehicles that conflicts with the requirements of the Federal motor vehicle safety standards.

I hope this information is helpful. If you have any further questions or need some additional information on this subject, please feel free to contact Mr. Kratzke at this address or by telephone at (202) 366-2992.

Sincerely,

Paul Jackson Rice Chief Counsel
