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.

59 Westover St.
West Roxbury, MA 02132-1317

Dear Mr. Bernten:

This is in reply to your letter of April 15, 1996, asking how "special purpose vehicles are classified", such as military four-wheel drive ambulances. You have also asked whether such vehicles may "be imported to be used as search and rescue vehicles in remote areas" of the United States."

Vehicles "manufactured for and sold to the Armed Forces of the United States, in conformity with contractual specifications" are exempt from compliance with the Federal motor vehicle safety standards (49 CFR 571.7(b)). However, this exclusion does not extend to military vehicles of countries other than the United States. Such vehicles are imported in the same manner as other vehicles not originally manufactured to comply with all applicable Federal motor vehicle safety standards, that is to say, through the procedures established by 49 CFR Parts 591- 94, which you tell us you have read. In brief, the manufacturer of the vehicle or a registered importer acting on your behalf, must file a petition for an eligibility determination pursuant to 49 CFR Part 593. If the petition is granted, the registered importer may import the vehicle under bond in order to bring it into conformance with the standards and provide this agency with compliance data. If the submission is satisfactory, we release the bond and the car.

If the military ambulance is a vehicle which is "designed to carry 10 persons or less which is constructed either on a truck chassis or with special features for occasional off-road operation," it is a "multipurpose passenger vehicle" as defined by 49 CFR 571.3(b). We deem it probable that a military ambulance is a vehicle that is manufactured on a truck chassis. Four-wheel drive is considered a "special feature" allowing use for off-road operations such as search and rescue. However, in the absence of more information about the vehicle, we cannot conclusively advise you that it is a "multipurpose passenger vehicle."

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

Sincerely,

Samuel J. Dubbin Chief Counsel

Dear Mr. Misumi:

This replies to your letter of April 22, 1996, to Enid Rubenstein of this Office asking for information on the applicability of the Federal motor vehicle safety standards to a limited-production vehicle you intend to manufacture in the near future. You have the following specific questions:

1. "Which FMVSS tests are applicable to us as an automobile manufacturer?"

Every manufacturer must meet all Federal motor vehicle safety standards, regardless of the size of its production, unless otherwise exempted by this agency pursuant to the procedures of 49 CFR Part 555. I enclose a copy of this regulation for your information.

2. "What are the estimated fees and costs of applicable FMVSS tests?"

I am sorry, but we have no information of the fees and costs that the various test laboratories charge private concerns.

3. "What is the time frame pertaining to the administration and completion of applicable FMVSS tests, relative to the vehicle production and sales cycle, (i.e., are tests to be administered and completed before any production vehicles "roll off" the production line, or can certification be completed after vehicles roll off the production line?)?"

Title 49 United States Code Chapter 301 - Motor Vehicle Safety does not require a manufacturer to conduct "tests", but it does require the manufacturer to produce motor vehicles that comply, and are certified as complying, with all applicable Federal motor vehicle safety standards. We advise manufacturers that, although the soundest way to assure compliance and the veracity of its associated certification is to test according to the procedures set forth in the standards, it may certify on the basis of computer simulations, engineering studies, mathematical calculations and

other reasonable substitutes for physical testing. Furthermore, it should retain the data in its files upon which its certification was based, in the event NHTSA ever asks the manufacturer to substantiate its certification.

Under 49 U.S.C. 30115 Certification of compliance, a manufacturer is required to "certify [compliance] to the distributor or dealer at delivery", and it "may not issue the certificate if, in exercising reasonable care, the [manufacturer] has reason to know the certificate is false or misleading in a material respect." Thus, a manufacturer should assure itself before applying the certification label that its vehicle fully conforms. This suggests that all test or other substantiating data be at hand at the time the first vehicle is certified. However, if a test laboratory has informed the manufacturer on an informal basis that it has tested a vehicle and found it to meet the performance requirements of a standard, the manufacturer could reasonably certify compliance before receiving the official test report.

The question you have asked is really best answered by the individual manufacturer based upon its best judgment and the legal considerations discussed above.

4. "What agencies or business entities administer FMVSS tests in the Los Angeles area?"

I enclose a list of test laboratories in the United States that NHTSA used in fiscal year 1995 to conduct its compliance testing. There may be additional testing labs that perform these services, and you may wish to consult other sources.

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

Mr. R. Karbowski

Dearborn, MI 48124

Dear Mr. Karbowski:

This responds to your May 3, 1996, facsimile asking whether New York=s proposed law requiring blind spot mirrors would be Aprohibited@ by our statute. Our answer is that the proposed State requirement would be preempted.

According to your letter, New York=s proposed law (9376--A, March 5, 1996) states, in relevant part:

[e]very motor vehicle sold after September first . . . shall be equipped with a blind spot mirror which is a convex mirror, circular in shape and 1.25 to 2.5 inches in diameter, that attaches directly on the standard side view mirror for cars, or of circular or rectangular shape, four inches to six inches in diameter or four inches by six inches, and is installed for trucks.

Federal Motor Vehicle Safety Standard No. 111, Rearview mirrors (49 CFR 571.111), prescribes performance requirements for side view mirrors on new cars and trucks. S5.2.1 of the standard specifies field of view requirements for the driver=s outside mirror on passenger cars and also specifies that the mirror shall be of Aunit magnification@ (i.e., flat). S5.3 provides the option of using a convex mirror in certain circumstances on the passenger side of a vehicle, and S5.4 specifies radius of curvature and other requirements for the convex mirror. S6, S7, and S8 specify requirements for truck rear view mirrors, including size. These sections require mirrors to be of unit magnification (with the exception of an option in S6 for mirrors complying with S5).

Section 30103(b) of 49 U.S.C. ''30101 et seq. (formerly '103(d) of the National Traffic and Motor Vehicle Safety Act) states:

when a motor vehicle safety standard is in effect under this chapter, a State . . . may prescribe or continue in effect a standard applicable to the same aspect of performance of a motor vehicle or motor vehicle equipment only if the standard is identical to the standard prescribed under this chapter.

New York=s Ablind spot mirror@ requirement appears to be preempted by Federal law. New York would be regulating the same aspect of performance (rear/side field of view) regulated by Standard No. 111. The state requirement would not be identical to the requirements of Standard 111. You state that complying with New York=s law would take some vehicles out of compliance with Standard No. 111. To the extent that New York=s requirement is inconsistent, it would be preempted.

It should be noted that NHTSA was petitioned to require convex rear view mirrors on the side mirrors, but denied this request. I have enclosed a copy of the denial for your information. (53 FR 45128)

Rockleigh, NJ 07647-0913

Dear Mr. Shapiro:

This responds to your May 6, 1996, letter asking about Federal Motor Vehicle Safety Standard No. 111, Rearview mirrors (49 CFR 571.111). You asked what position should be used to determine the driver's field of view for purposes of the standard's outside rearview mirror requirements, the rearmost seating position or the seating reference point. Your question arose from an inconsistency that you have identified in our standards. As discussed below, we plan to resolve this inconsistency in rulemaking. In the meantime, we will consider vehicles as being in compliance with the standard's outside rearview mirror requirements if they meet those requirements with the field of view determined at either the rearmost seating position or the seating reference point.

S5.2.1 of Standard No. 111 states that the driver=s side rearview mirror shall provide the required view Awith the seat in the rearmost position.@ (Emphasis added.) That section goes on to state that "the location of the driver's eye reference points shall be those established in Motor Vehicle Safety Standard No. 104 ('571.104) or a nominal location appropriate for any 95th percentile male driver." As you noted in your letter, Standard No. 104 specifies use of the seating reference point to establish the driver's eye reference points. The seating reference point establishes the "rearmost normal design driving or riding position," and not necessarily the absolute rearmost position. Since the rearmost seating position and the seating reference points may differ, fields of view based on these positions may differ.

As noted by your letter, this inconsistency was created as a result of recent rulemakings amending the definition of seating reference point and Standard No. 104. As a result of those rulemakings, the eye reference points in Standard No. 104 are no longer necessarily determined with the seat in the rearmost position. These rulemakings inadvertently created an inconsistency in Standard No. 111, since that standard retains the reference to rearmost position.

We plan to resolve this inconsistency in rulemaking. In the meantime, we will consider vehicles as being in compliance with the requirements of S5.2.1 of Standard No. 111 if they meet the performance requirements of that section with the field of view determined at either the rearmost seating position or the seating reference point.

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

Mr. Gerald Feldman
606 Victoria Avenue
Apt. 512
Saskatoon, Canada S7N 0Z1

Dear Mr. Feldman:

This responds to your e-mail to John Womack of this Office regarding your wish to import your 1991 Toyota Tercel passenger car into the United States later this year for use in the Washington, D.C. area. You have asked "what must be done or what papers must be obtained in order for me to properly register my vehicle in the U.S." You state that your vehicle has "a decal on the driver's doorpost clearly stating that the car DOES CONFORM to all federal safety and bumper standards in effect on the date of manufacture."

Because at the time in question Canada's certification wording requirements were identical to those of the Department of Transportation, the certification label on your car is ambiguous and can be read as a statement applicable to Canadian standards only, or to those of both Canada and the United States. For this reason, the U.S. Customs Service will allow entry of a privately-owned vehicle by the owner if the entry is accompanied by a letter from a vehicle's manufacturer attesting that the vehicle was manufactured in compliance with the U.S. Federal motor vehicle safety standards, except for minor labeling variances (if that is the case). If the Tercel was manufactured in Canada, you should obtain a letter from Toyota's Canadian office. If the car came from Japan, a letter from either Toyota USA or Toyota Canada would suffice. If Toyota will not provide you with such a letter -- and we understand that this may be its policy -- you may import the vehicle through the registered-importer process described below.

However, even if it is willing to provide a letter regarding vehicles that conform except for minor labeling variances, Toyota cannot provide such a letter to you if the Tercel does not have either automatic restraints at each front outboard passenger seat, or, alternatively, an air bag at the driver's seating position. These are requirements of Federal Motor Vehicle Safety Standard No. 208 that were in effect in the U.S. for the 1991 model year, but not in Canada. You can judge whether the vehicle was manufactured to meet these requirements by examining your car. In the event that it does not conform, you must contract with a "registered importer" (RI) to petition the agency for a determination that the Tercel is capable of being conformed to meet Standard No. 208, and to contract with the RI to conform the vehicle after entry if the petition is granted. The agency's Office of Vehicle Safety Compliance will provide you, upon your request, with the names of RIs in your area.

We are unable to advise you on the requirements of vehicle registration in the District of Columbia, Maryland, and Virginia, and advise you to contact the Department of Motor Vehicles where you wish to register the Toyota.

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

Samuel J. Dubbin Chief Counsel

Dear Mr. Haenchen:

This responds to your letter requesting an interpretation of Standard No. 208's sun visor labeling requirements. As noted by your letter, S4.5.1(b) requires a sun visor label with specific wording regarding certain cautions to avoid serious injury from possible air bag interactions with front seat vehicle occupants. You asked whether it is permissible to add to the sun visor label statements or references concerning side impact air bags for vehicles equipped with these devices. As discussed below, the answer is no.

You state in your letter that, in the interest of safety, Volkswagen believes it would be appropriate and desirable to add reference to side air bags to the sun visor label of vehicles equipped with these devices. You suggest adding a statement in the form of a heading, either above or below the phrase "Caution to Avoid Serious Injury," such as "This vehicle is equipped with front and side impact air bags." You also suggest adding the phrase "Front and Side Impact Air Bags" to the side of the sun visor with the air bag alert label.

Standard No. 208 specifically addresses the question of whether information in addition to the required cautions may be provided on the sun visor. S4.5.1(b)(2) provides that "(e)xcept for the information on an air bag maintenance label placed on the visor pursuant to S4.5.1(a) of this standard, no other information shall appear on the same side of the sun

visor to which the label is affixed." (Emphasis added.) That section also provides that "(e)xcept for the information in an air bag alert label placed on the visor pursuant to S4.5.1(c) of this standard, or in a utility vehicle label that contains the language required by 49 CFR 575.105(c)(1), no other information about air bags or the need to wear seat belts shall appear anywhere on the sun visor." (Emphasis added.)

You suggest in your letter that identifying phrases about side impact air bags are not really "other information" in general or "other information about air bags." However, the regulation's terms are sufficiently broad to include any references or statements about side impact air bags. I can only conclude that the highlighted language above prohibits adding to the sun visor label any references or statements about side impact air bags. I note that you can, of course, include such references or statements in locations other than the sun visor.

We believe it is appropriate, however, to consider whether particular statements on the sun visor should be permitted or required for vehicles with new kinds of air bags, such as air bags for side impact protection. In our newly issued notice of proposed rulemaking to reduce the adverse effects of air bags to children, we have specifically requested comments on that question. We would encourage you to address this issue in your comments.

If you have any further questions, please feel free to call Edward Glancy of my staff at (202) 366-2992.

Phebus, Winkelmann, Wong & Bramfeld
136 West Main Street
P.O. Box 1008
Urbana, Illinois 61801-9008


Dear Mr. Phebus:

This responds to your letter of May 7, asking about warning requirements for the lap belts provided with "motorized passive seat belts, such as utilized by Ford Motor Company." We assume that you are referring to a seating position equipped with both a motorized automatic shoulder belt certified to the automatic protection requirements of Standard No. 208, and with a separate manual lap belt. You ask whether certain warnings about fastening the lap belt were (a) required, (b) permitted, or (c) prohibited.

The lap belt for such a seating position was not required by the Federal motor vehicle safety standards but was instead voluntarily provided by the vehicle manufacturer to provide additional occupant protection. While automatic belts are required to have a special warning system (see S4.5.3.3 of Standard No. 208), no warning requirement applied to the voluntarily provided lap belt.

While none of the warnings you ask about were required, there is an issue, discussed further below, of whether they were permitted. Manufacturers may provide features in addition to those required by a standard, as long as the standard's requirements are met.

The specific warnings you ask about are as follows:

1. "That the chime that sounds when the lap belt is not buckled should be repeated at least twice at intervals of approximately one minute if the belt is not buckled."

Such a warning would not be permitted. S4.5.3.3 requires a warning system for automatic belts that, among other things, "activates a continuous or intermittent audible signal for a period of not less than 4 seconds and not more than 8 seconds and that activates a continuous or flashing warning light visible to the driver for not less than 60 seconds," to warn that the belt is not in use. Since the purpose of the audible signal is to

remind the driver to buckle up, it would be permissible to use the same signal to warn that the voluntarily provided lap belt is not in use. However, since the audible signal could not be activated for a period of more than 8 seconds, the system you describe would not be permitted.

I also note that NHTSA is limited by its authorizing statute as to what types of audible signals it may require, or permit as a means of compliance, to indicate that a safety belt is not in use. Under 49 U.S.C. 30124, 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." (Emphasis added.)

2. "The seat belt symbol light should remain on for at least one minute after the ignition is turned on and then flash off and on at 0.5 CPS for about 30 seconds and then remain lighted if the lap belt is not buckled. Further, the brightness of the signal should be increased when the dashboard lights are not on."

Assuming that the seat belt symbol light is only activated if the seat belts are not in use, such a system would be permissible. Since the purpose of the warning light for automatic belts is to remind the driver to buckle up, it would be permissible to use the same warning light to indicate that the voluntarily provided lap belt is not in use. Unlike the time period specified for audible signals, S4.5.3.3 specifies a minimum but not a maximum time for activation of the warning light. Therefore, the warning light could remain activated to indicate that a lap belt is not buckled.

3. "There should be an express instruction "fasten lap belt" which is located so as to be easily observed by both the driver and the occupant of the right front seat."

The Federal motor vehicle safety standards would not prohibit such a message.

4. "That sun visor warnings other than those used by Ford may be used which would employ colors and signal words and would communicate the nature of the hazards and potential consequences associated with not wearing the lap belts."

The sun visor warnings provided by Ford were provided voluntarily, and the Federal motor vehicle safety standards would not prohibit different messages. We have assumed that the vehicle does not have air bags. Standard No. 208 requires

specific sun visor warnings for vehicles equipped with air bags and restricts any additional information on the visor. See S4.5.1(b).

Dear Mr. DiGregorio:

This responds to your May 2, 1996, letter asking how Federal regulations would affect your product, a Atransparent tint@ film that sticks by static cling directly to the outside side view mirrors of vehicles. You state that the purpose of the product is to reduce glare from the mirror.

The National Highway Traffic Safety Administration (NHTSA) does not have any specific Federal motor vehicle safety standard directly applying to tint film for mirrors. However, if your product were manufactured for a new vehicle, Safety Standard No. 111, Rearview mirrors (49 CFR 571.111), would apply to the vehicle. Standard 111 prescribes construction requirements for all mirrors, including the driver=s outside mirror on passenger cars. S11 of the standard requires a single reflectance mirror to have an average reflectance of 35 percent. If your product were installed on a new vehicle, the vehicle manufacturer would have to certify that the mirror/film combination reflected at least 35 percent of incident light.

There are other Federal requirements that affect the manufacture and sale of your product. Your product is considered to be an item of motor vehicle equipment. As a manufacturer of motor vehicle equipment, you would be subject to the requirements concerning the recall and remedy of products with safety related defects. I have enclosed an information sheet that briefly describes those responsibilities. In the event that you or NHTSA determines that your product contains a safety-related defect, you would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge.

Manufacturers, distributors, dealers, and motor vehicle repair businesses are subject to a statutory provision, that prohibits them from Amaking inoperative@ any device or element of design installed in compliance with an applicable Federal safety standard. ...." A business, such as a car dealer or repair shop, could not install your film on a new or used vehicle if it reduced the mirror reflectance below 35 percent.

We do not regulate vehicle owners adding to or otherwise modifying their vehicles. Thus, if your product were installed by the vehicle owners, they would not need to meet any Federal motor vehicle safety standard. Nevertheless, NHTSA urges them not to degrade the safety of their vehicles.

Individual states have the authority to regulate the use of vehicles. As for information on state requirements, we suggest you contact the Department of Motor Vehicles in the states the tint will be sold or used.

Dear Mr. Clarke:

This responds to your letter asking several questions about the responsibilities associated with Agrooving windshields.@ We assume you refer to the process of grinding grooves into the lower portion of a windshield. The purpose of the grooves is to improve the efficacy of the windshield wipers.

I have enclosed copies of two letters on this subject, both addressed to Mr. Andrew Kallman, dated March 1, 1985 and October 28, 1988. These letters explain how the National Highway Traffic Safety Administration=s (NHTSA=s) regulations would apply if the grooves are ground into a windshield of a new vehicle, into a windshield sold as an item of replacement equipment, or into a windshield of a used vehicle.

Those letters address the issues you raise, and I will refer to them from time to time in answering your specific questions.

Question 1. Are you able to alter a previously certified item of motor vehicle equipment covered by Federal Motor Vehicle Safety Standard 205?

Answer: Our answer is yes, provided that certain requirements are met. As explained in the enclosed March 1985 letter, if the grooves are ground into the windshield of a new vehicle or into a new windshield sold as replacement equipment, the person making the grooves would have to ensure that the glazing continues to comply with all of the requirements of Standard 205. If the grooves are ground into the windshield of a used vehicle, any manufacturer, distributor, dealer or motor vehicle repair business must not make inoperative the compliance of the vehicle=s glazing with Standard 205. Individual owners may alter their vehicles as they please, as long as they adhere to all State requirements.

Question 2. If you did alter a previously certified item, could you now be construed the manufacturer and should now be perceived a Glazing Manufacturer with an I.D.#?

The answer depends on how the glazing is altered. NHTSA issues a manufacturer=s code mark only to "prime glazing manufacturers," which is defined at S6.1 as Aone who fabricates, laminates, or tempers the glazing material." If your company does not alter glazing in those ways (and merely adding grooves does not), you would not need, and NHTSA would not issue, a manufacturer=s code mark.

Question 3. If one now is to become a Glazing Manufacturer, how does one do so and how does one receive a Glazing I.D.#?

Prime glazing material manufacturers may receive a manufacturer=s code mark by writing NHTSA at the following address: Office of Vehicle Safety Compliance, NHTSA, Room 6111, Washington D.C., 20590 (telephone (202) 366-2832).

Question 4. For me now to proceed and groove windshields, what steps must I take to abide by the law and to hold my liabilities to a minimum and not be deemed negligent?

Our statute does not permit NHTSA to assure any person or entity that its product or processes comply with all applicable requirements or to Aapprove@ some product or process. Instead, our statute requires the manufacturer itself to certify that its products comply with all applicable safety standards, and to ensure they are free of safety-related defects.

The enclosed copies of the Kellman letters discuss your responsibilities for meeting NHTSA=s requirements, including Standard 205. You should also be aware of State requirements. In addition, you may want to check with a private attorney for your responsibilities under State tort law.

Please feel free to contact Paul Atelsek of my staff at (202) 366-2992 if you have any further questions.

Sincerely,

Samuel J. Dubbin Chief Counsel
