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. Lucki:

This responds to your letter requesting an interpretation of Federal Motor Vehicle Safety Standard No. 102, Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect. You asked whether a planned gear position display for automatic transmission vehicles would meet the standard's requirement that full gear position information be provided in a single location. As discussed below, the answer to that question is yes.

By way of background information, the National Highway Traffic Safety Administration does not provide approvals of motor vehicles or motor vehicle equipment. Under the National Traffic and Motor Vehicle Safety Act, it is the responsibility of the manufacturer to ensure that its vehicles and equipment meet applicable standards. The following represents our opinion based on the facts provided in your letter.

As you are aware, on March 26, l99l, this agency published in the Federal Register a final rule amending Standard No. l02. Among the amendments is a new S3.l.4.4 that requires, for all automatic transmission vehicles, that full gear position information, i.e., identification of shift level positions, including the position of the gears in relation to each other, and the gear position selected, be displayed "in view of the driver in a single location."

According to a drawing enclosed with your letter, your planned gear position display would be located on the instrument panel, between the speedometer and tachometer. The current gear position, either P, R, N, D, 3, 2, or l, would be shown in a square, by means of electronic display. The position of the gears in relation to each other, i.e., P R N D 3 2 1, would be marked adjacent to the electronic display. You state that the gear positions in relation to each other will be illuminated when the headlamps are activated.

It is our opinion that your planned design would meet S3.l.4.4's requirement that full gear position information be displayed in a single location. The gear position selected would be shown in the square electronic display. The position of the gears in relation to each other would be marked adjacent to the electronic display. Because the marking of the position of the gears in relation to each other would be adjacent to the electronic display, it is our opinion that all of the information would be considered to be provided in a single location.

I note that this same issue was addressed in the preamble to the March l99l final rule, in connection with a comment submitted by Chrysler. The agency stated the following:

If Chrysler wishes to provide a display of current gear position information on the instrument panel, it is free to do so. Under the amendment, it can either provide full gear position information at that location, e.g., include a "P R N D L" label adjacent to the display, or it can provide a display of current gear position information only on the instrument panel and include a display of full gear position information elsewhere, e.g., on the floor console. 56 FR l2470, March 26, l99l.

Your proposed design is consistent with the first of the two options discussed in that paragraph.

I hope this responds satisfactorily to your concerns. If you have any further questions, please contact Dorothy Nakama of my staff at (202) 366-2992.

Mr. Ron Dawson
4224 Quince Road
Portsmouth, VA 23703

Dear Mr. Dawson:

This is in reply to your e-mail of March 3, 1999, telling us that you are preparing a business plan to produce a new kit car. You have asked about our policy regarding kit car manufacturing, and, specifically, the Federal motor vehicle safety standards (FMVSS) that apply to a kit car manufacturer.

Under your plan, you would sell "all necessary parts required to formulate an automobile except for engine and gear box." These parts would be new. You would sell the kit of parts "in any stage of assembly from a box of unassembled parts to a completely assembled automobile minus engine and gearbox." The purchaser of the kit would provide "a previously owned or used engine and gearbox." The purchaser would assemble, or complete assembly of, the vehicle. The vehicle would be for personal use, on public roads, and not for resale.

We have no regulations that apply per se to the manufacture of kit cars. However, a seller of motor vehicle equipment is subject to the statutory requirement that the equipment item must conform to all applicable FMVSS, if any are in effect that cover the equipment item. We find that, generally, equipment manufactured in the United States is certified by its manufacturer as conforming to applicable FMVSS. The items of passenger car motor vehicle equipment that are the subject of specific Federal motor vehicle safety standards are brake hoses (FMVSS No. 106), items of lighting equipment (FMVSS No. 108), pneumatic tires (FMVSS No. 109), brake fluids (FMVSS No. 116), non-pneumatic temporary spare tires (FMVSS No. 129), glazing materials (FMVSS No. 205), and seat belt assemblies (FMVSS No. 209).

This equipment is required to be marked with a DOT symbol as a certification of compliance (alternatively, the containers of lighting equipment other than headlamps may bear a certification statement). Therefore, you may rely upon this certification, unless NHTSA or the manufacturer has determined that a noncompliance exists.

We have encountered compliance problems from time to time with equipment manufactured outside the United States, particularly lighting equipment. Were you to import noncomplying equipment for a kit, we would regard you as the manufacturer of the equipment and responsible for notifying purchasers and remedying the noncompliance through repurchase of the equipment, or replacing it with a complying item, at no expense to the owner, even if the equipment were certified. You would also be liable for civil penalties for importing and selling noncomplying equipment if it is not certified. If the noncomplying equipment is certified, you would not be liable for a penalty unless you actually knew the equipment was noncompliant.

You may assemble the vehicle up to the point of installation of its power train without becoming its manufacturer. However, if you decided to furnish an engine and transmission with the kit, we would consider you the manufacturer and responsible for the vehicle's noncompliance with all applicable FMVSS, and certifying compliance, even though the vehicle would be assembled by another person. In the situation you describe, in which you do not furnish the engine and transmission, the person installing the engine and transmission, whether the kit purchaser or a commercial entity such as a repair facility, would be regarded as the manufacturer of the vehicle, and responsible for its compliance with the FMVSS. The fact that the kit car may be equipped with a used transmission and engine is not sufficient to relieve it of the legal necessity to comply with all FMVSS that apply to motor vehicles manufactured from all new parts.

Of course, the kit car must meet all State and local requirements in order to be registered and operated.

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

TITLE: FMVSR INTERPRETATION

TEXT: This is in reply to your letter of March 8, 1982, asking the current status of three-wheeled motor vehicles under the Federal Motor Vehicle Safety Standards.

As you know from my letter of November 24, 1976, to HM Vehicles, a copy of which you enclosed, three-wheeled motor vehicles are classified as "motorcycles" under the standards. Obviously the configuration of a three-wheeled enclosed vehicle differs greatly from that of the two-wheeled machine that comes to mind when the word "motorcycle" is mentioned. As my 1976 letter indicates, the agency was seeking a more realistic regulatory scheme for three-wheeled vehicles, for obviously our motorcycle standards were written with two-wheeled vehicles in mind. But because three-wheeled vehicles did not comprise a significant part of the market, the agency decided that its priorities in motor vehicle safety lay elsewhere, and no change in the definition of "motorcycle" was ever adopted, and it still encompasses three-wheeled vehicles.

You have also asked whether a three-wheeled vehicle can be registered and inspected as a passenger car. Under the preemption provisions of the National Traffic and Motor Vehicle Safety Act 15 U.S.C. 1392(d)), Pennsylvania is bound to treat three-wheeled vehicles as "motorcycles" in those areas that are covered by Federal safety standards that apply to motorcycles. Further, it may apply its own motorcycle standards in areas not covered by Federal standards. This means, for example, that Pennsylvania could not require a three-wheeled vehicle to have two headlamps since one is adequate under our Safety Standard No. 108. On the other hand, Pennsylvania could require a backup lamp device since Standard No. 108 contains no such requirement for motorcycles. Thus, it would seem that Pennsylvania should register and inspect these vehicles as motorcycles to the extent possible.

As a final comment, we favor the use of discretionary enforcement when literal enforcement may create disrespect for the law. We note the comment written on the "Free-Way II" sheet: "must wear a helmet." Our standards do not cover the use of helmets or apparel of operators but we can understand why the driver of an enclosed three-wheeled vehicle might not understand a citation for failure to wear a helmet. On the other hand, such a requirement appears perfectly reasonable for the operator of an open three-wheeler.

Mr. Wolfred Freeman
Freeman & Company
P.O. Box 5062
San Marcos, CA 92069

Dear Mr. Freeman:

This is in reply to your letter to June 22, l989, to the Administrator-Designate, General Curry, in which you "petition...for permission to produce a color coded (Green-Amber-Red) rear light device for all types of motor vehicles." You have designed "a workable auxiliary system that can be adopted to cars and trucks on the road."

We are treating your letter as a request for an interpretation of whether your device would be permissible for sale and use as an item of aftermarket equipment under the regulations and statutes administered by this agency. By aftermarket, we mean sale of the device for installation on cars and trucks in use, as contrasted with sales by dealers for installation on new cars. The principal regulation of this agency pertaining to motor vehicle lighting equipment is Federal Motor Vehicle Safety Standard No. l08. The only requirements it establishes for the aftermarket is for equipment that is intended to replace the original lighting equipment specified by the standard (for example, headlamps and stop lamps). As your device is not a required item of motor vehicle lighting equipment, there is no Federal standard that applies to it.

However, the National Traffic and Motor Vehicle Safety Act has a direct relationship to the acceptability of aftermarket equipment. The Act prohibits modifications by persons other than the owner of the vehicle if they render inoperative, in whole or in part, equipment that is installed pursuant to a safety standard. Under Standard No. l08, this equipment includes stop lamps, turn signal lamps, hazard warning signals, turn signals, backup lamps, taillamps, and the license plate lamp. On large trucks, it also includes identification lamps and clearance lamps. If the potential effect of an auxiliary lighting device is to create confusion as to the intended message of any lighting device required by Standard No. l08, we regard the auxiliary light as having rendered the required lamp partially inoperative within the prohibition of the Act.

Thus, the question is whether your device has the potential to create confusion so that its installation by a manufacturer, distributor, dealer, or motor vehicle repair business would be a violation of the Act. We do not conclude that the device has this potential. In your device, a steady-burning amber light would signal that the accelerator had been released (and that neither the accelerator nor brake pedal were being applied). Amber is the recognized signal for caution. This signal will extinguish when either the accelerator (green signal) or brake pedal (red signal) is applied. Furthermore, it is steady burning whereas other rear lamps where amber is an optional color (turn signals and hazard warning signals) flash in operation. Therefore, it does not appear that your device would create confusion with required items of lighting equipment.

You must also consider whether the device would be acceptable under the laws of any State where it is sold and used. We are unable to advise you on State laws, and recommend that you contact the American Association of Motor Vehicle Administrators, 4600 Wilson Boulevard, Arlington, Va. 22203. However, we believe that in several Western States, there has been specific legislation that would permit your device.

We appreciate your interest in enhancing vehicle safety through improvement in rear lighting systems. We believe that improvements, such as the center highmounted stop lamp, should be introduced as standardized, mandatory lighting equipment on vehicles, rather than as optional aftermarket devices. Contrary to your understanding, our studies of a system similar to yours showed no discernible improvement in reaction time or accident avoidance over current systems.

Sincerely,

Stephen P. Wood Acting Chief Counsel

Mr. Lou McKenna
Emergency Vehicle Alarm
2800 N. Hamline Avenue, #130
Roseville, MN 55113

Dear Mr. McKenna:

We are replying to your letter of February 20, 2000, with a copy to Sante Esposito, as you requested. You have written us for an interpretation as to whether the proposed placement of your Emergency Vehicle Alarm (EVA) is acceptable under relevant Federal laws and regulations, as your long-range goal is "to have the EVA installed as an original equipment manufacturer device on all passenger vehicles."

The EVA has three principal features, two in the interior of a vehicle and one on the exterior. Inside the vehicle, a flashing red display of the words "Emergency Vehicle" on the instrument panel is triggered by a signal from an emergency vehicle. At the same time, "an animated siren also sounds inside the car." On the exterior, a "flashing white light" indicates to the driver of an emergency vehicle that the warning has been received. This lamp is located "to the left of the Center Highmounted Stop Lamp (CHMSL)" as viewed from the rear, "equidistant from the CHMSL and the "window corner and equal in height to the CHMSL."

None of the laws and regulations that we administer preclude a flashing red message on the instrument panel or an audible siren in or on a motor vehicle. This means that the legality of such devices must be determined under state and local laws. We are not conversant with these laws.

However, the "flashing white light" is subject to our laws and regulations. Federal Motor Vehicle Safety Standard No. 108, Lamps, Reflective Devices and Associated Equipment (49 CFR 571.108), requires all lamps installed on "passenger vehicles" to be steady-burning in use, except for turn signals, hazard warning signals, and headlamps and side marker lamps flashed for signaling purposes. See S5.5.10. This requirement would preclude the use of the flashing-light feature of the EVA system either as original or optional equipment. We are also of the opinion that this feature could not realistically be offered as aftermarket equipment either. Under 49 U.S.C. 30122, a "manufacturer, distributor, dealer, or motor vehicle repair business" may not "make inoperative" any element or device installed in accordance with a Federal motor vehicle safety standard. Because the installation of the flashing white light would result in a noncompliance with Standard No. 108, we would consider that action to be a "making inoperative" within the meaning of that phrase, and a violation of Section 30122 if performed by one of the four persons named in the prohibition. The system appears too complex for installation by a person other than a manufacturer, distributor, dealer, or motor vehicle repair business (e.g., the vehicle owner).

Were the EVA reconfigured so that the white light is steady burning, the question would then arise whether it is acceptable under S5.1.3 of Standard No. 108 as optional new vehicle equipment. The test of permissibility under S5.1.3 is whether a lamp not required by Standard No. 108 impairs the effectiveness of equipment required by Standard No. 108. We believe that the EVA lamp could create confusion in a following driver other than that of an emergency vehicle. In this sense, the CHMSL and other stop lamps would be impaired if the following driver delayed in responding to a stop signal.

We note also that state laws often prohibit a white light to the rear, other than a license plate lamp, as do the Vienna Conventions on motor traffic.

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

AIR MAIL

Mr. Brad G. Magor 6282 Young Street Halifax, Nova Scotia B3L-1ZB Canada

Dear Mr. Magor:

This is in reply to your letter of May 1, l990, to the Department of Transportation with respect to your intended purchase of a Canadian truck or van which you will eventually import into the United States. You asked for information on the features required to meet the U.S. safety standards, and whether Canadian vehicles generally have these items.

There is a great similarity, but not identicality, between the Canadian Motor Vehicle Safety Standards (CMVSS), and the Federal Motor Vehicle Safety Standards (FMVSS). Manufacturers in both countries are required to affix a label to their vehicles certifying compliance with all applicable safety standards. We understand that some Canadian manufacturers may have certified compliance of their vehicles with both the CMVSS and the FMVSS. If dual certification has occurred, it will be evident from reading the certification label on the vehicle (usually located in the driver door post area). If the vehicle bears a certification of compliance that includes the FMVSS, you should encounter no problems in importing, registering, and selling it in the United States.

However, if the vehicle is certified only to the CMVSS, you will encounter some difficulty in importing it, notwithstanding the substantial similarity of the CMVSS and FMVSS. By direction of Congress, a vehicle not originally manufactured to conform to the FMVSS may not be admitted into the U.S. unless two things have occurred. The vehicle must be on a list of vehicles that the Department has approved for conversion to the FMVSS. If this has occurred, then the vehicle can only be imported by a "registered importer" (i.e. converter), or one who has a contract with a registered importer to perform the conversion work. A bond equal to l50% of the entered value of the vehicle must be given to secure performance of the conversion work, which is cancelled upon satisfactory evidence that the work has been performed.

The new directives of Congress were only effective on January 31, l990, and we are still working to implement them. We have tentatively proposed an approved general list of vehicles that would include all Canadian trucks and vans manufactured since January 1, l968, that were certified as meeting the CMVSS, and which are of the same make, model, and model year of any truck or van originally manufactured for importation into and sale in the United States, or originally manufactured in the United States, and that were certified as meeting the FMVSS. For example, a l990 Chevrolet truck manufactured in Canada to the CMVSS with a U.S. manufactured and certified counterpart would be covered by this general list. We have received no objections to treating Canadian vehicles in this fashion. A final determination should be published in the near future. We have also accorded registered importer status to a number of applicants. If you choose to buy a vehicle certified to the CMVSS for importation into the United States, we will be pleased to provide the latest list of registered importers as the time draws near for your departure.

The minor differences in the standards that may effect you are principally those regarding speedometer/odometers and lighting. The former must indicate miles and miles per hour (and may indicate kilometers and kilometers per hour). Vehicles must be equipped with headlamps that meet the FMVSS and not those of the ECE. Thus, once a CMVSS-certified vehicle is imported, we do not anticipate that the conversion work should be lengthy or costly. Once the work has been satisfactorily performed and the converter's label attached, you should encounter no difficulties in registering the vehicle or in selling it.

I hope that this answers your questions.

ATTACHMT: ATTACHED TO LETTER DATED 9/26/94 FROM FRANK LAUTENBERG TO SUSAN SLYE

TEXT: We are responding to your further correspondence on behalf of your constituent, Dr. Mark L. Bauman of Marlton, which was addressed to the Federal Highway Administration. On July 28, 1994, the Deputy Administrator of the National Highway Traffic Safety A dministration (NHTSA) wrote you about Dr. Bauman's courtesy light. I believe that letter fairly states NHTSA's views on the process the government generally follows for mandating items of safety equipment. This letter will explain what Dr. Bauman may n ow do if he wishes to sell his invention as an item of optional motor vehicle lighting equipment, without the necessity of Federal involvement.

Dr. Bauman's light would be mounted in the front of a vehicle so that its driver, stopped at an intersection, can advise pedestrians or other drivers to proceed with caution. Federal Motor Vehicle Safety Standard No. 108 Lamps, Reflective Devices and As sociated Equipment governs the installation of lighting equipment on new motor vehicles. Since Standard No. 108 does not require a front courtesy light, the light is considered supplementary lighting equipment, one for which no standards have been estab lished. Supplementary lighting equipment is permissible provided that it does not impair the effectiveness of the lighting equipment that the standard does require, in this instance, the other lighting equipment on the vehicle's front, specifically park ing lamps, turn signal lamps, and headlamps (paragraph S5.1.3, Standard No. 108). The vehicle manufacturer is required to certify upon the vehicle's completion that it complies with all applicable Federal motor vehicle safety standards. With respect to certification of a vehicle on which the courtesy light has been installed, a manufacturer would be certifying under S5.1.3 that the light does not impair the effectiveness of the required lighting equipment. NHTSA will not question the certification un less it appears to be clearly erroneous. Thus, any tests that Dr. Bauman may conduct with the courtesy light should address the basic issue of impairment. A dealer in motor vehicles must not negatively affect the vehicle manufacturer's certification. Thus, if a dealership installs the courtesy light, it should ensure that there is no impairment within the meaning of S5.1.3 before offering the vehicle for sale and selling it. Our regulations make a distinction between modifications to new vehicles an d those that have been sold, but similar considerations apply. If a dealership installs the courtesy light on a used car, it must ensure that it does not "make inoperative" any of the required lighting equipment (49 U.S.C. 30122). We have interpreted t his, where possible, to be the equivalent of the "impairment" prohibition applicable to new vehicles. This prohibition applies to manufacturers, distributors and motor vehicle repair businesses as well.

However, the prohibition does not extend to the vehicle owner. If Dr. Bauman intends his courtesy light solely for the aftermarket and the device is such that it would ordinarily be installed by the vehicle owner, the legality of its use is determined b y the laws of the States in which it is operated. We are unable to advise Dr. Bauman on whether the laws of the individual States would permit use of his invention, and recommend that he write for an opinion to the American Association of Motor Vehicle A dministrators, 4600 Wilson Boulevard, Arlington, Va. 22203.

I hope that this responds to Dr. Bauman's concerns.

Gentlemen:-

The early part of this year we arranged to handle a Vehicle named Haflinger, through Overland Vehicle Corp. of North Miami Beach, Florida, the imported. This vehicle is built in Austria. We are attaching a fly covering the specifications.

The Haflingers we have sold were 1967 Models, ie; built prior to January 1, 1963. All have been sold to operators of Ranches, such as the King Ranch. This vehicle is designed for cross-county, off the highway use. It has a maximum speed of forty-seven miles per hour.

The 1967 models we received were equipped with Seal-Beam Headlights, Parking and Stop-Lights. Directional Signals with Amber Side Lights mounted on each side at the front of the vehicle, tail and licence plate lights and windshield wipers.

About ninety days ago we placed an order with Overland Vehicle Corporation for twenty Haflingers accompanied by a letter of Credit. One of the conditions of the Letter of Credit, was that the vehicle would meet the Federal Safety Standards. We have been unable to contact any one during the last thirty days with the Overland Vehicle Corporation, and it appeared they had closed their office in North Miami Beach.

We have now been in communication with the Manufacturer of the vehicle in Austria and they advise that their contract with Overland expires August 31, 1963 and they have offered to sell us direct. This vehicle has created a lot of interest among farmore and ranchers in the area, as well as hunters.

It will be appreciated if you will give us an official ruling as quickly as possible of the Safety Standards necessary to enable us to import this vehicle for sale in the United States.

Thanking you, we are

Yours very truly,

TITLE: FMVSS INTERPRETATION

TEXT:

Mr. John E. Bennett Director - Research & Engineering Truck-Lite Co., Inc. 310 East Elmwood Avenue Falconer, New York 14733

Dear Mr. Bennett:

This in response to your letter of April 12, 1983, asking for interpretation of paragraph S4.6(b) of Motor Vehicle Safety Standard No. 108.

This paragraph states in pertinent part that "means may be provided to flask...side marker lamps for signalling purposes." You have first asked whether the rear side marker can be made to flash. You have also asked whether this language may be interpreted as allowing both front and rear side marker lamps to be flashed. The answer to both questions is yes. In the absence of restrictive language, paragraph S4.6 may be interpreted as allowing flashing of either front or rear side marker lamps, or both sets of lamps.

You have also asked whether, where the rear side marker and taillamp used the same optical source ("minor filament of a 1157 or similar bulb"), it is acceptable to have an overriding signal lamp is actuated. The answer is yes. The standard's prohibition against optical combinations (paragraph S4.1.1) does not preclude this design.

We hope that this answers you questions.

Sincerely,

Frank Berndt Chief Counsel

Subject: Request for interpretation of an element of FMVSS-108

Dear Sir:

In our endeavor to continue the advancements of vehicle lighting devices, which is a continuing assignment within our company, and offer specialized products to our customers with inherent benefits to the consumers, we have under consideration a new product which requires an interpretation of Section S4.6 Item (b), FMVSS-108, before we finalize our programs.

This section (S4.6) of FMVSS-108 requires.. "when activated:

a. Turn signal lamps, hazard warning signal lamps, and school bus warning lamps shall flash; and b. All other lamps shall be steady burning, except that means may be provided to flash headlamps and side marker lamps for signalling purposes."

Our questions are in reference to the rear side marker lamp and item (b) above. They are stated as follows:

a. Can the rear side marker be made to flash? Is Section S4.6, Item (b) to be interpreted as both front and rear side marker lamps may be flashed for signalling purposes? We know of only one current production (Jeep CJ) vehicle which the rear side marker lamp might be so viewed.

b. In a design where the rear side marker function and the rear tail lamp use the same optical source (minor filament of a 1157 or similar bulb), is it acceptable to have an overriding-flashing signal visible through the rear side marker lens when the signal lamp is actuated?

We are attempting to market a new product within the near future and do not wish to proceed until the above is cleared. Therefore we would appreciate your response to your questions as soon as possible.

Kindly accept our thanks for your prompt attention to this request. Do not hesitate to contact me if I can be of additional assistance.

Sincerely,

TRUCK-LITE CO., INC.
