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.

Mr. Joe Rutman President, Pathway Ltd. P.O. Box 88111 Grand Rapids, MI 49580

This is in reply to your letter of October 16, 1986, with reference to an electronic message display known as "Tellite"

We have reviewed your letter and our letter of February 10, 1986, to Timothy Pawl that you enclosed. The interpretation to provided Mr. Pawl was posited on the fact that Tellite was "in close proximity" to the center highmounted stop lamp which, in the a bsence of further explanation, we assumed meant either to the right or left of it. Your letter, however, indicates that the message function may be superimposed over the center lamp, though operating independently of it. Before we provide a definitive re sponse to your letter of October 16, 1986, we would appreciate your providing us with a photo or drawing of Tellite so that we will have a better understanding of it. We should also like to know what messages it is intended to display.

Sincerely,

Attention: Erika Z. Jones, Chief Counsel

Dear Ms. Jones:

Pathway Ltd. previously corresponded with you through a potential joint venture party regarding DOT approval of a concept which we now hope to move forward and promptly develop. Pathway has developed an electronic message display known as "Tellite". We b elieve, based on prior correspondence, that the circuitry and display conforms with, or is at least not in violation of, any NHTSA regulations or standards. Please note that this display board will incorporate the red, third brake light located in the re ar window of the vehicle. The circuitry for the red brake light is independent of the message circuitry and overriding. In other words, in the event that the brake is depressed, the third stop light (red LEDs) illuminates and the amber message LEDs are o verridden and are not illuminated during braking. (The amber message board is approximately 4 inches wide and 2 inches high).

It is our intention initially to sell this product as an aftermarket installation. However, we are also interested in pursuing the original equipment manufacturers. The purpose of this letter is to specifically request any direction you might provide reg arding whether our concept, as outlined, fails in any way to comply with any Federal (NHTSA) regulations for installation in the rear window of a passenger vehicle.

You should also know that the amber message board would not flash during display.

I look forward to your response. Please direct any further correspondence to my attention, Joe Rutman, President, Pathway Ltd., P.O. Box 88111, Grand Rapids, MI 49508. Thank you.

Very truly yours

Joe Rutman

Re: Whether market and sale of headlamp covers are regulated by Federal law

Dear Mr. Burman:

This is in reply to your letter of January 9, 1987, asking for an interpretation of 49 CFR 571.108 Motor Vehicle Safety Standard No. 108 Lamps, Reflective Devices, and Associated Equipment. Your client wishes to import, market, distribute and sell a "cle ar, plastic headlamp cover...for all makes of cars manufactured in or imported to the United States." The stated safety purpose of the headlamp cover is "to protect the glass headlamps on automobiles from breaking."

Three methods of distribution are contemplated: direct sale by your client, sale through auto parts distribution centers, and sale as optional but uninstalled equipment at the time of the vehicle's original sale (the cover in its wrapping would be in the vehicle trunk). You state that the headlamp cover is not intended to be installed by your client, or its distributors and dealers, but will be accompanied by instructions so that the vehicle owner may install it. Warnings will be provided "about minimum Federal photometric requirements". You wish to know whether the headlamp cover is subject to Standard No. 108 or any other Federal regulation and, if so, the effect and impact of such regulation.

A plastic headlamp cover is "motor vehicle equipment", defined in pertinent part by Section 102(1) of the National Traffic and Motor Vehicle Safety Act (15 USC 1391(4)) as "any...accessory, or addition to the motor vehicle...." Its importer is a "manufac turer", defined in pertinent part by Section 102(5) of the Act as "any person importing...motor vehicle equipment for resale". As a manufacturer of motor vehicle equipment your client has the responsibility imposed by Sections 151 et seq of the Act to no tify and remedy in the event that either it or this agency determines that a safety related defect exists in the product, or that it fails to comply with all applicable Federal motor vehicle safety standards. You have already noted that headlamp covers a re not "a regulated safety device" under Standard No. 108. A "defect" under Section 102(11) includes "any defect in performance, construction, components, or materials". Under the best of circumstances a plastic cover when new will reduce light output of a headlamp beneath its designer's intent, whether or not the output falls below the floor established by Standard No. 108 as a minimum for headlamp performance. In service, a plastic headlamp cover may contain condensation under certain climatic conditi ons, or grow increasingly opaque through exposure to ultraviolet rays or other atmospheric components, either of which would further affect the design performance of the headlamp. A conclusion could be reached that such a cover contained a safety related defect and that its importer should notify all purchasers and remedy according to the Act.

Safety problems associated with headlamp covers led to their prohibition when the headlamp is in use, initially under SAE J580 for sealed beam headlamps and later by its incorporation into Standard No. 108, for both sealed beam and replaceable bulb headl amps. The specific prohibition of J580 is why passenger cars are not manufactured with original equipment headlamp covers. Under Section 108(a)(l)(A) of the Act, if a dealer sells a noncomplying motor vehicle, he is in violation of the Act, and may be su bject to civil penalties for it. These penalties, under Section 109, range up to $1000 for a single violation, with a cumulative total of $800,000 for a related series of violations. If a dealer at time of sale provides the means through which a new car meeting all Federal safety standards may be rendered noncompliant immediately after its delivery, we would regard that as tantamount to his having sold a noncomplying motor vehicle in violation of the Act.

Although there is no Federal prohibition against a vehicle owner installing and using headlamp covers, there may nonetheless be local laws covering the sale and use of this equipment. We offer no views of your client's potential exposure under common law , in such situations as use of a deteriorated cover, or when used with a substandard replacement headlamp, except to note that photometric "warnings" may serve no defensive purpose. Photometric values at the individual test points are judged under labora tory conditions. Service facilities do not contain equipment by which on-vehicle compliance of the headlamp can be judged, and the eye is a subjective and unreliable source to discriminate between complying and noncomplying levels of light output.

I hope that this answers your questions.

Sincerely,

Erika Z. Jones Chief Counsel

January 9, 1987

National Highway Traffic Safety Administration Erika Z. Jones, Chief Counsel 400 7th Street, S.W. Washington. DC 20590

Re: Letter ruling to determine if market and sale of headlamp covers are regulated by federal law

Dear Ms. Jones:

REQUEST FOR RULING

Our client is in the process of forming a Texas corporation (the "Company") to engage in those activities described below, and, on its behalf, we are requesting an interpretation of Motor Vehicle Safety Standard No. 108 Lamps, Reflective Devices, and Ass ociated Equipment ("Standard 108") and other related or applicable rules or regulations of the Department of Transportation. The reason for this request is the lack of specific guidance in determining (i) if the product our client will import, market and sell will be subject to such regulation, or any other federal regulation, and, (ii) if so, the effect and impact of such regulation. The product, which the Company intends to market, sell and distribute and for which the Company seeks approval by the Na tional Highway Traffic Safety Administration ("NHTSA"), is a clear, plastic headlamp cover (the "Headlamp Cover") for all makes of cars manufactured in or imported to the United States.

STATEMENT OF FACTS

The Company proposes to engage in the importation and marketing of the Headlamp Cover, either through direct sales to ultimate consumers or through sales to automobile dealers, distributors and automotive parts distributors. The Headlamp Cover is designe d to protect the glass headlamps on automobiles from breaking. The Company, distributors, automotive dealers and others will not physically install the Headlamp Cover on automobiles. However, the Company does intend to provide warnings and instructions i n the packaging so that the owner of the vehicle may purchase the proper Headlamp Cover and safely install it.

The Company, proposes to distribute the Headlamp Cover in one or more of the following manners:

1. Over-the-counter. The Company wishes to market and distribute its Headlamp Cover to auto parts distributor centers for sale to the consumer. These distribution centers will be instructed not to participate in the installation of the Headlamp Cover.

2. Option offered by Dealer. The Company will sell and distribute the Headlamp Cover to automotive distributors and dealers who will offer them as accessories to purchasers of new automobiles. The automotive distributors or dealers will place the Headlam p Cover, in its original packaging, in the trunk of the automobile and will not install it for the consumer. Automotive distributors of imported automobiles will place the Headlamp Cover in trunks of automobiles at the port of arrival and list the Headla mp Cover on the price sticker as well as the invoice to the dealer.

3. Direct to consumer. The Company also desires to sell its Headlamp Cover directly to consumers, again, with no installation services offered.

CHRYSLER RULING

The Company is aware of a fairly recent denial of petition for rulemaking by the NHTSA regarding an attempt by Chrysler Corporation ("Chrysler") for an amendment to Standard 108 to allow Chrysler to offer removable transparent Headlamp Covers as original equipment on motor vehicles manufactured by Chrysler. It is our client's understanding that such petition was denied primarily because Chrysler's Headlamp Covers caused a reduction in light output between 7.2% and 15.5% and it was conceivable that certa in replacement headlamps purchased by consumers would produce an unacceptable light output when used in conjunction with the Chrysler Headlamp Cover.

The Company believes its proposed activities should be differentiated from those of Chrysler and should not be subject to federal regulation. The differences between the Company's proposal and Chrysler's proposal are: (i) the Company intends to market an d sell, but not manufacture and install, the Headlamp Cover, (ii) the Headlamp Cover is not a regulated safety device as defined in Standard No. 108, (iii) the Headlamp Cover will not be original equipment installed on an automobile at the time of purcha se and will not be installed by the Company. the distributor or the dealer, as prohibited by SAE J580 Sealed Beam Headlamp Assembly and (iv) the Headlamp Cover will not be marketed as a dealer installed option.

Additionally, the Chrysler ruling dealt specifically with the sealed beam headlamp assembly while the Company proposes to initially sell Headlamp Covers for the bulb and reflector type headlamp assembly found on many makes of cars sold in the United Stat es today.

However, similar to Chrysler, the Headlamp Cover, when used with original headlamps furnished by the manufacturers of the automobiles, will satisfy minimum federal photometric requirements.

CONCLUSION

The Company believes its activities should not be compared to those of Chrysler. It is aware that there may exist circumstances or possibilities where the Headlamp Cover may be misused, but intends to make information available to all parties who sell th e Headlamp Cover directly to consumers regarding photometric warnings. The product will also be packaged so that warnings are found on the exterior of the package to warn consumers about minimum federal photometric requirements. The interior of the packa ge will contain complete and accurate instructions for consumer installation of the Headlamp Cover.

The Company questions whether the Headlamp Cover or the contemplated activities of the Company, the distributors and dealers who will sell the Headlamp Cover, fall within federal regulated guidelines. Therefore,the Company hereby requests a ruling differ entiating its sale of the Headlamp Cover from Chrysler and permitting the Company. and the distributors and dealers to whom it sells the Headlamp Cover, to market and sell this product in accordance with the procedures discussed above.

We appreciate your attention to this matter and would be grateful for your prompt response.

If we can provide you with additional information, please do not hesitate to contact us.

Very truly yours,

Darryl M. Burman

Douglas C. Fairhurst, Esq. Townley & Update 405 Lexington Avenue New York, NY 10174

Thank you for your letter concerning how the requirements of Standard 208, Occupant Crash Protection, would apply to an arrangement Jaguar has made for having its XJS hard-top model imported into the United States altered to become a convertible. You hav e raised a number of issues in your letter, which are addressed below.

You explained that "Jaguar has entered into a contractual arrangement with a company that specializes in converting hard-top vehicles into convertible models, the essential provisions of which obligate Jaguar to cooperate with and assist the converter in the latter's effort to secure orders from Jaguar's retail dealers for converting Jaguar XJS models imported into the United States into convertibles." You further explained that "The retail dealers to whom Jaguar sells the XJS will be encouraged to have any conversion work they desire to have done on the vehicles performed by this particular converter, although of course, they remain free to have conversion work done by anyone else if they so wish. Essentially Jaguar will facilitate the arrangement wit h its converter by making shipments of vehicles designated for conversion work by dealers directly to the converter's facilities. Under the contract, the converter has the responsibility of certifying that the vehicles on which it performs this work rema in in compliance with all applicable motor vehicle safety and emissions standards . . . ."

The first issue you raised is the application of S4.1.3.1.1 of the standard to this arrangement. That section requires each vehicle manufacturer to install automatic restraints in at least 10 percent of the passenger cars it produces during the time peri od, September 1, 1986 to August 31, 1987. You stated that Jaguar intends to meet the 10 percent requirement by installing automatic safety belts in its XJS models. You asked whether, assuming all the XJS models imported into the United States have automa tic safety belts and the total number of XJS models far exceeds the number of vehicles jaguar must equip with automatic restraints to meet the 10 percent requirement, it would be a violation of section 108(a)(2)(A) of the National Traffic and Motor Vehic le Safety Act for Jaguar's dealers and Jaguar's authorized converter to remove the automatic safety belt in the "excess" vehicles and install manual Safety belts that comply with the requirements of Standard No. 208 and 209 in those vehicles.

It would not be a violation of section 108(a)(2)(n) for Jaguar's dealers and the converter to alter the "excess" XJS hard-top models into convertibles and reinstall manual rather than automatic safety belts into the altered vehicle. Under our certificati on regulation, a person that alters a certified vehicle must certify that the vehicle, as altered, conforms with all applicable safety standards. The agency has previously said, such as in a January 11, 1979 letter to James Brown, that when a vehicle is altered from one vehicle type to another, the alterer must certify that the vehicle conforms to the safety standards that apply to the new vehicle type, in this case a convertible. Convertibles are temporarily exempt from the automatic restraint requirem ents of Standard No. 208 during the phase-in period, and may instead have either a manual lap or lap/shoulder belt.

Please note that the agency's final decision in the ongoing rulemaking on applying the automatic restraint requirement to convertibles may affect the conversion of hard-top cars into convertibles. If the agency does not exempt convertibles permanently fr om the automatic restraint requirement, then a vehicle alterer would have to ensure that the altered cars still complied with the automatic restraint requirement. Likewise, if the agency applied a dynamic test requirement to the manual safety belts used in convertibles, a vehicle alterer would have to equip an altered vehicle with either manual safety belts meeting the dynamic test requirements or with an automatic restraint system.

Having addressed the issue of the alterer's responsibility, I would like to explain how these conversions affect Jaguar. It is Jaguar's responsibility under section 4.1.3.1.1 to produce 10 percent of its passenger cars equipped with automatic restraints during the first stage of the phase-in period. In the factual situation you have described, jaguar has entered into a contract to facilitate the conversion of some of its automatic restraint-equipped hard-top models into manual belt-equipped convertibles before the cars are first sold to a consumer. Since Jaguar has consented to the conversion, and in fact will be encouraging its dealers to use a particular "authorized" converter, jaguar cannot count a vehicle that has undergone an authorized conversion in determining whether it has produced sufficient vehicles equipped with automatic restraints. These conversions would reduce both the number of cars that would have to be equipped with automatic restraints, and the number that are equipped with such re straints. Thus, Jaguar should carefully monitor the number of conversions to ensure that there will still be a sufficient number of automatic restraint-equipped vehicles to still be a sufficient number of automatic restraint-equipped vehicles to meet S4. 1.3.1.1.

I also want to address one further issue concerning the altered vehicles. S4.1.3.1 of the standard provides a carryforward credit to manufacturers for the automatic restraint equipped vehicles they produce in excess of the required phase-in percentages. Since, as explained above, Jaguar cannot count vehicles that have undergone an authorized conversion in determining whether Jaguar has met the phase-in requirements, Jaguar also cannot use those vehicles for the purpose of the carryforward credit.

If you have any further questions, please let me know.

Sincerely,

Erika Z. Jones Chief Counsel

Erika Jones, Chief Counsel National Highway Traffic Safety Administration 400 Seventh Street, S.W. Washington, D.C. 20590

Dear Ms. Jones:

This follows up our discussion last Thursday regarding the post-September 1, 1986 passive restraint requirements of FMVSS 208 as they would apply to the arrangement jaguar has made in the United States for having XJS hard-top models made into convertible s. At the conclusion of our meeting, I said I would frame the specific question on which Jaguar sought an advisory opinion from NHTSA and relate to you the material facts.

The salient facts are these. Jaguar has entered into a contractual arrangement with a company that specializes in converting hard-top vehicles into convertible models, the essential provisions of which obligate Jaguar to cooperate with and assist the con verter in the latter's efforts to secure orders from Jaguar's retail dealers for converting Jaguar XJS models imported into the United States into convertibles. The XJS, as I explained, is the 12 cylinder, two-door sports model which Jaguar offers to its dealers in two versions, the XJS-HE, which is the, hard-top coupe and the XJ-SC Cabriolet, the latter having the open-top feature of a convertible, but with the "B post" intact and a removable top consisting of interlocking targa panels. The retail deal ers to whom Jaguar sells the XJS will be encouraged to have any conversion work they desire to have done on the vehicles performed by this particular converter, although, of course, they remain free to have conversion work done by anyone else if they so wish. Essentially Jaguar will facilitate the arrangement with this converter by making shipments of vehicles designated for conversion work by dealers directly to the converter's facilities. Under the contract, the converter has the responsibility of cer tifying that the vehicles on which it performs this work remain in compliance with all applicable motor vehicle safety and emissions standards, and, as I explained, there are provisions under which Jaguar will be providing the converter with financial as sistance.

The issue I raised respecting the applicability or Regulation S4.1.3.1.1 (49 C.F.R. 571.208, S4.1.1.3.2) to this project arises by virtue of the intention of Jaguar to meet its obligation to fit passive restraint systems in no less than 108 of the vehicl es Imported into the country between September 1, 1986 and September 1, 1987 by installing automatic seat belts in the XJS models I have just described. The specific question Jaguar poses to NHTSA is whether, if all of the aforementioned XJS models impor ted into the United States were equipped with automatic seat belts (this being a number far exceeding the actual number of vehicles that need be fitted with such belts in order for Jaguar to meet the 108 requirement), it would be lawful under the Safety Act for Jaguar's dealers and the converter with which Jaguar has made this contract to remove the automatic belts in the "excess" vehicles and refit these vehicles with manual seat belts that comply with the requirements of FMVSS 208 and 209 as these app ly to convertibles? This removal and refitment operation is necessary because the process of converting the vehicle entails removal of the "B post" to which part of the assembly mechanism used in the automatic seat belt is affixed. As I say, the converte r will be recertifying that each converted vehicle conforms to all applicable federal motor vehicle safety standards and Jaguar will be selling to its dealers sufficient numbers of XJS models equipped with automatic seat belts to meet its 108 obligation.

Since the converted vehicles would continue to meet the requirements of FMVSS 208 and 209, it was and remains my view that under these circumstances the removal of automatic belts installed by the factory on an "optional" basis would not "impair" or rend er inoperative any device installed to meet a safety standard and hence would not constitute a violation of 15 U.S.C. S1397(a)(2)(a).

We would appreciate confirmation of this view and any other comments you feel are appropriate.

Very truly yours,

Mr. Dwight R. Koehler Product Management Parker Industries P.O. BOX 37589 Omaha, NE 68137

Dear Mr. Koehler:

This is in reply to your letter of December 9, 1986, with respect to agricultural (grain) transportation vehicles which you manufacture, known in the industry as "grain buggies." You have asked whether there are any DOT lighting requirements for these ve hicles, and if so, what are they and how might you meet them.

You have described the grain buggies as designed to be towed by agricultural tractors, with a top road speed of 25 to 3Q mph. You have also told us that "the primary use for these trailers will be 'off road' in nature," although "there are times when the se units will be used on gravel roads and occasionally, highways."

The requirements of Federal Motor Vehicle Safety Standard No. 108 Lamps Reflective Devices, and Associated Equipment apply to various categories of "motor vehicles.' A "motor vehicle" is defined as a vehicle driven or drawn by mechanical power and manufa ctured primarily for use on the public streets, roads, and highways. The manufacturer of a vehicle determines whether his product is a "motor vehicle" and therefore a vehicle that must comply with all applicable Federal motor vehicle safety standards inc luding Standard No. 108. The National Highway Traffic Safety Administration reserves the right to challenge any determination that appears clearly erroneous. On the basis of the information you have presented us, the grain buggies will be primarily used off the public roads, and u e of the public roads will be only incidental (in our experience agricultural equipment uses public roads for such limited purposes as crossing from one field to another, and delivery of produce to processing plants). Under th ese circumstances, we would not consider the grain buggies as "motor vehicles," and no Federal requirements would apply to them. They would, however, remain subject to any appropriate requirements of the State in which they are used.

I hope that this answers your questions.

Sincerely,

Erika Z. Jones Chief Counsel

Dear Ms. Jones:

We are a manufacturer of agricultural grain transportation vehicles, also known in the industry as "Grain Buggies". We manufacture 4 different models. (ref. enclosed product literature)

Although the primary use for these trailers will be "off road" in nature, we realize there are times when these units will be used on gravel roads and occasionally, highways. They are designed to be towed by agricultural tractors, which generally have a top road speed of 25 to 30 MPH.

Since we market these units over a wide geographic area, we felt the need to incorporate a comprehensive safety lighting system, which would conform to any Department of Transportation specifications for said vehicles if there were indeed any such specif ications.

We need to know two things:

1. Are there any DOT lighting requirements for these types of vehicles?

2. If there are any requirements, what are they and how can we meet them?

I have included some general descriptions of our products for your review.

We are committed to producing quality, safe equipment for our customers. Your response to our questions will help us meet our commitments.

Mr. George Ziolo 16182 Arena Drive Ramona, CA 92065

Dear Mr. Ziolo:

Thank you for your letter of September 19, 1986, concerning the labeling requirements of Standard No. 209, Seat Belt Assemblies. Those requirements provide that each safety belt is to be labeled with the year of its manufacture. You asked whether the yea r of manufacture can be shown in code. As explained below, the answer is no, the standard does not provide for showing the year of manufacture in code.

S4.1(j) of the standard requires each safety belt to be permanently and legibly labeled with the name of the manufacturer, distributor, or importer, the model of the safety belt model, and "the year of manufacture." The standard specifically requires the date of manufacture to be provided on the belt and does not provide for the use of a code to represent that date.

The purpose of the labeling requirement is to make it possible for the agency and consumers to identify easily the manufacturer of the safety belt for the purpose of noncompliance and safety-related defect investigations and notification and remedy campa igns. In addition, having the date of manufacture clearly marked on the belt assists consumers in determining whether a particular belt complies with the latest requirements of Standard No. 209 or some earlier version of those requirements. It also assis ts the agency in compliance testing of aftermarket and other safety belts because it enables the agency to determine easily which version of the standard should be applied to that safety belt. Having the year shown in a code can complicate the easy ident ification of which safety belts are covered by an investigation or campaign and make it more difficult to determine which version of the standard applies to the safety belt.

If you have any further questions, please let me know.

ATTACHMT: LETTER DATED 11/14/86, TO STEPHEN L OESCH, FROM BINICHI DOI; OCC - 1437

TEXT: Dear Mr. Doi:

Thank you for your letter of November 14, 1986, to Stephen Oesch of my staff concerning how our regulations would apply to a device intended to make it easier to reach the belt or latchplate of a safety belt system. I hope the following discussion answe rs your questions.

You enclosed a sketch with your letter that shows that the device would be attached to the vehicle by the anchorage bolt for the upper torso portion of a lap/shoulder safety belt. You explained that the device, called an "arm" or "belt reacher", is made of material which "does not interfere with the general safety/comfort of passenger and is installed semi-rotationally around the shoulder-anchor point so that it can hold the tongue in a convenient position" for the occupant to reach the belt.

There are no safety standard that directly apply to the device described in your letter. However, if the device is installed as an item of original equipment on a new vehicle, then the vehicle's safety belt system would have to continue to comply with a ll of the requirements of Standard No. 208. Thus, for example, if the device is installed on a vehicle that must comply with the comfort and convenience requirement of S7.4 of the standard, it must continue to meet those requirements, such as the the re traction requirements of S7.4.5, with the device in place. Likewise, the safety belt anchorage would have to continue to comply with all of the performance requirements of Standard No. 210.

There is one further issue associated with the device shown in your letter that I want to address. The agency supports the use of equipment that will make safety belts easier and more comfortable to use. However, it is equally important that those devi ces not introduce excessive slack in the upper torso belt and thereby reduce the effectiveness of that belt. You stated in your letter that the device is made of a material that makes it compliant so that it moves with the belt and does not

interfere with the "original protective function" of the safety belt. If you should implement the design depicted in your letter we encourage you to continue to make sure that the device will not introduce excessive slack in the belt.

If you have any further questions, please let me know.

Sincerely,

ATTACHMT: LETTER DATED 11/17/86 FROM JOHN GRIFFIN TO TAYLOR VINSON, OCC 1443

TEXT: Dear Mr. Griffin:

This is in reply to your letter of November 17, 1986, to Taylor Vinson of this Office with respect to the status of identification and clearance lamps on emergency medical service vehicles (ambulances).

You believe that Federal requirements often present a conflict with respect to installation of these lamps at locations specified by the Standard. As an example you have cited "a light bar above the double rear doors may be placed as high as possible an d thereby give no room for identification lights." You have asked for a clarification of Federal requirements.

You are correct that Standard No. 108 does not exempt emergency-type motor vehicles from compliance; further, it contains no special provisions for them. This means that the final-stage manufacturer of such vehicles must meet the same requirements as the manufacturers of other vehicles whose overall width exceeds 80 inches, and give priority in lamp placement to fulfilling the locational requirements of Table II of Standard No. 108. The requirements for clearance and identification lamps are expressed in terms of practicability, however, and the determination of whether a certain location is "practicable" is initially that of the manufacturer who installs them. There may be State laws governing the placement of lightbars, or practical considerations that may necessitate placing identification and clearance lamps at a position other than "as close as practicable to the top of the vehicle", and in these instances the lamps may be located at a lower height than they would be were the lightbar absent. The lamps, however, cannot be omitted and the agency retains the right to review the determinations of the manufacturer.

I hope that this provides the guidance that you seek. If we may be of further help, please let us know.

Sincerely

Mr. John F. Doerr 100 Lefferts Ave. 4D Brooklyn, NY 11225

This is in reply to your letter of December 12, 1986, to Secretary Dole on your "Safety Light Warning System." You have asked if your system "could legally be implemented" and for advice "how I may go about marketing this system."

The patent drawing of your device depicts a light bar mounted in the rear window area with a green lamp in the center flanked by amber lamps, with two red lamps at the end. This system would be acceptable neither as original equipment on passenger cars, nor as replacement equipment on passenger cars manufactured on or after September 1, 1985. As of that date, Federal Motor Vehicle Safety Standard No. 108 requires passenger cars to be manufactured with a red stop lamp in the approximate location of your green lamp. There is no Federal prohibition against offering the system in the aftermarket for retrofitting on passenger cars manufactured before September 1, 1985, but the system would be subject to the laws of each State in which it would be sold or us ed. I understand that Oregon and California allow green-amber-red deceleration warning systems when the lamps are mounted on the rear of the car, but restrictions may exist as to their mounting in a vehicle's interior.

I hope this information is useful to you.

Sincerely,

Erika Z. Jones Chief Counsel

Mrs. Elizabeth Dole Secretary of Transportation Department of Transportation 400 7th Street NW Washington, DC 20590 Dear Mrs. Dole:

Subject: SAFETY WARNING LIGHT SYSTEM

I know you are concerned about rear end collisions, extra "eye-level stop light" confirms this.

I have a patent on this system which I believe will be more effective. This system consists of a small green light st eye-level which burns when you are gaining or maintaining speed. When you release the accelerator the green light goes off and the yello w or amber caution goes on, on each side warning the driver behind you to be alert which gives the driver a second or more to react, then, if you apply the brakes, caution lights goes off and normal stop light, lights go on, on each side at eye-level.

This information was sent to all auto makers in the United States and some abroad. They like the idea but are not interested in negotiating with me, as they don't accept ideas from anyone other than their own engineers.

I am interested to know if this could legally be implemented and if you could give me any advice or information as to how I may go about marketing this system.

Enclosed, is a brief description and my patent # 4,470,036.

Sincerely,

John F. Doerr Inventor

Mr. David A. White Senior Safety Engineer Grumman Olson Post Office Box 2005 Sturgis, MI 48091

Dear Mr. White:

This letter responds to your inquiry of November 17, 1986, asking this agency to approve an alternate location for the certification label of a light duty truck your company intends to manufacture for the United States Post Office. Section 567.4 of the N ational Highway Traffic Safety Administration (NHTSA) regulations requires that a motor vehicle manufacturer affix a certification label to each vehicle it makes, and permits the manufacturer to place the label in any one of the places set out in that pr ovision. If none of those locations is practicable, S567.4 directs the manufacturer to suggest an alternate place to affix the label, and to ask our approval for that alternative.

You explain in your letter that in the circumstances you describe, the S567.4 locatons are impractical. First, you explain, the vehicle's small and irregularly shaped for a label. Second, if your company places the label on the inside of the sliding door , opening the door would hide the label. Third, you assert that the instrument panel is too small for a label.

You enclose a drawing to illustrate where your company intends to place the certification label. According to your description, the certification label will be placed on a fixed panel behind the driver, and between the cab and the load compartment. This panel is one part of a three piece assembly of which the remaining two components are a center sliding door and a second fixed panel. You state that a person can see the certification label from the driver's area without moving any vehicle item.

In directing a manufacturer to put its certification label in those places set out in S567.4, NHTSA's purpose is to make these labels easy to see and read. Based on the information you supplied, the agency determines that for this particular design, inst alling the certification label as your company proposes will facilitate seeing and reading the label, while placing the label as specified in S567.4 may not be practicable or might interfere with those activities. Therefore, on the condition that your co mpany's label complies in all other respects with S567.4, NHTSA grants your request to install the certification label on the forward side of the left hand bulkhead fixed panel.

Sincerely,

Erika Z. Jones Chief Counsel

November 17, 1986

Administration of National Highway Traffic Safety Administration Washington, D.C. 20590

Grumman Allied Industries, Inc., LLV Division would like to request approval of an alternate location for the certification label of a light duty truck to be manufactured for the U.S. Post Office. The locations specified in 49 CFR 567.4 are not practical for the following reasons:

1. The vehicle has sliding side doors making the hinge pillar, door latch post, and door edge too small and irregularly shaped to accept a label.

2. A label placed on the inward facing side of the side door would be covered up by the vehicle structure when the door is opened.

3. The instrument panel is too small to accept a label.

Grumman Allied Industries proposes to locate the label on the forward side of the left hand bulkhead fixed panel. This bulkhead is located behind the driver between the cab and load compartment. The bulkhead is a three piece assembly consisting of a cent er sliding door and two fixed panels. The door slides to the right when opened. The certification label will be in view from the drivers area without moving any vehicle item. I am enclosing a copy of drawing 85616200 to show the location we are proposing .
