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. Christopher Banner
618 Osage Street
Manhattan, KS 66402

Dear Mr. Banner:

This responds to your request for an interpretation of how NHTSA's regulations would apply to some manufacturing operations you are contemplating. I apologize for the delay in this response. In a telephone conversation with Dorothy Nakama of my staff, you explained that you would like to start producing vehicles based on Ford pickup truck chassis. Some of these Ford chassis would come from wrecked vehicles that you would strip down to the frame, and others would be new chassis that you would purchase directly from Ford. You would then install new bodies on top of some of these chassis and offer them for sale as completed vehicles. You also would like to offer some of these bodies and chassis for sale as "kit cars." In the "kit car" version, you would sell the body and chassis to the purchaser of the kit, and the purchaser of the kit would have to furnish some other parts in order to complete the vehicle.

This agency's Federal motor vehicle safety standards apply to new motor vehicles and new items of motor vehicle equipment. Federal law does not require motor vehicles and items of motor vehicle equipment to continue to comply with the safety standards after the first purchase of the vehicle or equipment item in good faith for purposes other than resale. However, Federal law does prohibit any manufacturer, distributor, dealer, or repair business from knowingly "rendering inoperative" compliance with a safety standard for a vehicle or item of equipment. See 15 U.S.C. 1397(a)(1)(A), (a)(2)(A), and (b)(1).

1. New Body on New Chassis. All vehicles you produce by installing a new body on a new chassis would be considered new vehicles. You would have to certify that each of those vehicles conformed to all applicable safety standards. You would be considered a "final stage manufacturer" of the vehicles, as that term is used in 49 CFR Parts 567 and 568.

2. New Body on Used Chassis. We cannot say from the information you have provided whether the vehicles you produce by installing a new body on a stripped, wrecked Ford pickup would be treated as a new vehicle, and have to be certified as complying with the applicable safety standards. The answer depends on how extensively you modify the Ford pickup chassis.

To allow vehicle modifiers to determine when the modifications to a used chassis are so extensive that the resulting vehicle will be considered new for the purposes of the Federal safety standards, NHTSA has established specific criteria at 49 CFR 571.7(e), Combining new and used components. That section reads as follows:

When a new cab is used in the assembly of a truck, the truck will be considered newly manufactured . . . unless the engine, transmission, and drive axle(s) (as a minimum) of the assembled vehicle are not new, and at least two of these components were taken from the same vehicle.

This provision means that if you leave the frame, engine, transmission, and drive axle in place from the wrecked vehicle, and place a new body on top of it, we would consider that vehicle to be a used vehicle, which would not have to be certified by you as complying with applicable safety standards. On the other hand, if you were to remove all the drive components from the frame of the Ford pickup chassis, and add new drive components or rebuilt drive components from different vehicles, the vehicle would be a new vehicle and would have to be certified by you as complying with all applicable safety standards.

3. Kit cars. Under the National Traffic and Motor Vehicle Safety Act, a "motor vehicle" is defined, in part, as one that is "driven by mechanical power." See 15 U.S.C. 1391(3). We have interpreted this provision to mean that a unit would be considered only an assemblage of motor vehicle equipment, and not a motor vehicle, until such time as a power source is added. None of the Federal motor vehicle safety standards apply to assemblages of motor vehicle equipment, or to used equipment items in the assemblage (items used on a vehicle previously in service on the public roads). However, certain of the safety standards would apply to new equipment items included in the assemblage. It would be a violation of Federal law if your kit car includes any new brake hoses, brake fluid, lighting equipment, tires, glazing, or seat belt assemblies that do not comply with the applicable safety standards.

If you ship your kit cars with all parts needed to produce a completed motor vehicle, including the power source, this agency will treat the kit car as a motor vehicle, not an assemblage of motor vehicle equipment, regardless of the state of completion of the kit. You would be required to certify that the kit car conformed to all applicable safety standards if it were treated as a new vehicle under the rules set forth in 1. and 2. above, but not if it were treated as a used vehicle under those rules.

I have enclosed for your information a general information sheet for manufacturers of new vehicles. This sheet highlights the relevant Federal statutes and regulations and explains how to obtain copies of them. I have also enclosed a brochure titled "Federal Motor Vehicle Safety Standards" that briefly describes each of the safety standards.

I hope this information is useful. If you have any further questions or need further information, please contact Dorothy Nakama of my staff at (202) 366-2992.

Sincerely,

John Womack Acting Chief Counsel

The Honorable Beverly B. Byron
Member of Congress
U.S. House of Representatives
Westminster District Office
6 North Court Street
Westminster, MD 21157

Dear Ms. Byron:

Thank you for your recent letter on behalf of your constituent, Mr. Joseph L. Ciampa, Jr., who received a citation from the Maryland State Police, Automotive Safety Enforcement Division, for noncomplying window tinting. You asked us to review Mr. Ciampa's letter and provide you with our comments and appropriate information. I am pleased to have the opportunity to do so.

Mr. Ciampa suffers from diabetes, which makes his eyes extremely sensitive to sunlight. Because of this, the side windows on his passenger automobile apparently were tinted such that the tinted glazing no longer complied with State of Maryland requirements. There is no indication whether Mr. Ciampa did the tinting on his own or had an aftermarket business do it. According to Mr. Ciampa's letter, he was previously given a medical exemption by the State of Maryland that permitted him to drive with windows tinted differently than Maryland law permits. However, Mr. Ciampa stated that Maryland officials have now told him that the Federal government will not allow Maryland to grant any more medical exemptions. This information is inaccurate.

Some background information on the Federal requirements in this area may be helpful. Our agency, the National Highway Traffic Safety Administration (NHTSA) is authorized, under the National Traffic and Motor Vehicle Safety Act, to issue safety standards applicable to new motor vehicles and certain items of motor vehicle equipment. The safety standard that specifies performance and location requirements for glazing used in vehicles is Standard No. 205, Glazing Materials (49 CFR 571.205). These requirements include specifications for minimum levels of light transmittance (70 percent in areas requisite for driving visibility, which includes all windows in passenger cars). Under Standard 205 no manufacturer or dealer is permitted to install solar films and other sun screen devices in a new vehicle, without certifying that the vehicle continues to be in compliance with the light transmittance and other requirements of the standard. Federal law does not permit States to grant any exemptions, including medical exemptions, from the safety standards. Thus, we assume that Mr. Ciampa's car as delivered to him complied with Standard No. 205's requirement for at least 70 percent light transmittance in all of its windows, including the side windows that are now the subject of dispute.

The requirement that a car comply with all applicable safety standards applies only until the car is first sold to a consumer. After a vehicle is first sold to a consumer, any modifications to the vehicle's windows, including the tinting performed on the side windows of Mr. Ciampa's car, are affected by section 108(a)(2)(A) of the Safety Act. That section prohibits any manufacturer, dealer, distributor, or repair business from "rendering inoperative" any device or element of design installed in a vehicle in compliance with any safety standard. In the case of windows in a passenger car, this means that no manufacturer, dealer, distributor, or repair business could install a sun screen device or window tinting that would result in a light transmittance of less than 70 percent for any window of the car, or otherwise cause the car to no longer comply with the other requirements of Standard No. 205. Violations of this "render inoperative" prohibition can result in Federal civil penalties to the manufacturer, dealer, distributor, or repair business of up to $1000 for each noncomplying installation.

Again, Federal law does not permit States to grant any exemptions, including medical exemptions, from the "render inoperative" prohibition in Federal law. Thus, the State of Maryland does not have any authority to permit manufacturers, distributors, dealers, or repair businesses to install tinting on the side windows of passenger cars if such tinting causes those windows to have less than 70 percent light transmittance. Instead, the manufacturer, distributor, dealer, or repair business that installed such tinting on Mr. Ciampa's side windows would be liable for the civil penalty discussed above.

Please note that Federal law does not affect vehicle owners. Vehicle owners may alter their own vehicles and operate them on the highways as they please, even if the vehicle's windows no longer comply with the requirements of Standard No. 205. Hence, no provision of Federal law or this agency's regulations prevents Mr. Ciampa himself from tinting his side windows.

However, each of the individual States has the authority to regulate the modifications that may be made to vehicles by their owners and to establish requirements for vehicles to be registered or operated in that State. It would seem that the State of Maryland has exercised its authority to prohibit windows being tinted in the way that Mr. Ciampa's are. The wisdom and fairness of applying that prohibition to individuals with Mr. Ciampa's condition is something to be decided by the State of Maryland, not the Federal government. Contrary to the statement in Mr. Ciampa's letter, we have never told Maryland or any other State how to administer their laws and regulations with respect to the operational use of vehicles in the State. I hope this information is helpful. If you have any further questions or need some more information on this subject, please do not hesitate to contact Ms. Susan Schruth of my staff at this address, or by telephone at (202) 366-2992.

Sincerely,

Erika Z. Jones Chief Counsel

Mr. Clarence M. Ditlow III
Executive Director
Center for Auto Safety
2001 S Street, NW
Suite 410
Washington, DC 20009

Dear Mr. Ditlow:

This responds to your most recent letter to me concerning retrofitting of cars originally equipped with rear seat lap belts with rear seat lap/shoulder belts. In my November 1, 1988 letter to you, I explained that we have sought the voluntary cooperation of manufacturers to make retrofit kits available for those customers who desire them and that the vehicle manufacturers have responded positively to our efforts. I also explained that the fact that retofit kits are not available for all model lines produced by each manufacturer does not suggest some failure on the part of the vehicle manufacturers or of our policy to encourage the manufacturers to make such retrofit kits available.

In a November 7, 1988 letter, you asserted that my November 1 letter "reflects such callous disregard and ignorance of the facts as to defy belief that you are doing little more than covering up for a GM policy that will kill rear seat passengers." You stated that you would welcome a "substantive response" to this letter. I am happy to be able to give you such a response.

Let me begin by emphasizing that the lap belts in the rear seat of most vehicles on the road today are effective in reducing the risk of death and injury in a crash. Based on our analysis of a number of crash data files, we estimate that rear seat lap belts saved about 100 lives and prevented over 1500 serious injuries in 1987 alone. These figures would have been substantially higher if more rear seat occupants used their lap belts. In fact, if everyone had worn their rear seat lap belts each time they rode in a vehicle, those belts would have saved about 660 lives and prevented more than 10,000 serious injuries in 1987 alone.

These facts illustrate that the fastest and most effective way to save the greatest number of lives and prevent the greatest number of injuries is to convince the public to use the safety belts, including the rear seat lap belts, that are in their vehicles every time they ride in those vehicles. Because of these facts, I do not accept your assertion that GM's policy of not providing rear seat lap/shoulder belt retrofit kits for a few of their past models will "kill people." To the extent that reckless assertions like this tell the public that they should not wear their rear seat lap belts, it is unfortunate that you have chosen to divert attention away from the overriding issue of convincing the public to use their safety belts, and instead chosen to mislead the public about the quality of their safety belts.

Even though lap belts have been proven to be effective in reducing the risk of death and injury in a crash, we agree that properly designed lap and shoulder belts have the potential to offer even greater crash protection than lap belts alone. For this reason, we have proposed to require that all new passenger cars sold in the United States be equipped with rear seat lap and shoulder belts beginning in the 1990 model year. Additionally, we have actively sought the car manufacturers' cooperation in providing retrofit kits to interested consumers. As you may know, every domestic manufacturer and many foreign manufacturers now offer retrofit kits for many of their vehicle models.

You objected to General Motors' (GM) statement in its Information Bulletin that retrofit kits are not offered for its 1978-88 Oldsmobile Cutlass, Buick Regal, Chevrolet Monte Carlo, or Pontiac Grand Prix, "because GM safety engineers have concluded that in these cars, a rear seat lap/shoulder belt combination would not enhance the safety offered by the lap belt alone." You asserted that since Leonard Evans, a GM employee, has concluded that lap/shoulder belts are significantly more effective than lap belts and since the National Highway Traffic Safety Administration (NHTSA) is proposing to require rear seat lap/shoulder belts, there is no "possible scientific basis" for GM's conclusion.

NHTSA's proposal reflects our tentative conclusion that rear seat lap/shoulder belts that are designed and installed at the factory have the potential to offer even greater crash protection than lap belts alone for vehicles in general. However, any particular vehicle model's floor pan design, seat stiffness, and seat design (as it relates to occupant posture) can affect the possibility of an occupant submarining under a lap/shoulder belt system in a crash. During the design and production of the vehicle, the vehicle manufacturer can take these factors into account to minimize the likelihood of such submarining and its associated consequences.

However, this is emphatically not true for vehicles that were not originally engineered and designed to use rear seat lap/shoulder belts as original equipment. With respect to these vehicles, the effectiveness of a retrofitted rear seat lap and shoulder safety belt system may well depend on the belt system's compatability with the vehicle and the installation of the belt system. The suitability of a particular vehicle for retrofitting is therefore a complex question. It is our view that the judgment as to whether a retrofit lap/shoulder belt system should be installed in a particular vehicle is best made by a vehicle manufacturer, which is most familiar with the detailed seat and structural design and crash performance of the car.

I hope this information is helpful. Please let me know if you have any further questions or would like some additional information on this subject.

Sincerely,

Erika Z. Jones Chief Counsel

FROM: AUTHOR UNAVAILABLE; Frank A. Berndt; NHTSA

TO: Fleming Metal Fabricators

TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your December 3, 1976, letter concerning the relationship between Federal Motor Vehicle Safety Standard No. 301-75, Fuel System Integrity, and the fuel tanks that you manufacture for vehicles with a gross vehicle weight rating of 10,000 pounds or less.

Standard No. 301-75 applies to whole vehicles rather than to fuel tanks. Therefore, the responsibility under Federal law for compliance with the standard lies with the vehicle manufacturer. He must exercise due care in certifying that the vehicle will, if tested by the NHTSA as specified in S6 and S7 of the standard, meet the fuel spillage requirements set out in S5. What constitutes "due care" in a particular case depends on all relevant facts, including such things as the limitations of current technology, the availability of test equipment, the size of the manufacturer, and above all the diligence evidenced by the manufacturer.

The vehicle manufacturer who installs a fuel tank manufactured by you may, in order to meet his duty to exercise due care, rely on assurances from you concerning the tank's performance characteristics, to the extent that such reliance is reasonable. Your assurances, in turn, need not necessarily be based on actual crash testing of vehicles equipped with your fuel tanks under the exact conditions prescribed in the standard.

You should both note, of course, that the ability of a vehicle to conform to the standard depends not only on the performance capabilities of the fuel tank itself, but also on other factors including the manner and location in which it is mounted. The fact that your fuel tanks conform with Federal Highway Administration requirements (49 CFR @@ 393.65 and 393.67), therefore, does not by itself imply that vehicles equipped with such tanks are capable of passing the crash test requirements of Standard No. 301-75.

Similarly, the fact that your company's manufacturing procedures and its mounting and installation instructions conform to established industry practices is not sufficient evidence of due care, unless it is reasonable to conclude from it that the vehicles will conform.

FLEMING METAL FABRICATORS

3 December, 1976

Frank Berndt Office of Chief Council Dept. of Transportation SUBJECT: 571, 301-75 Fuel System Integrity with certification per Part 567 -- by auxilliary gasoline tank installers (Truck Body Builders, New Truck Dealer, Truck Repair Facility, Etc.). To discover bases for responsible certifying to Safety Standard 301 without performing actual tests or without reference to factory vehicle tests.

Pursuant to our telecon of 2 December, 1976, we present the following information hoping that some answer can be found to this very perplexing problem.

We are strictly manufacturers, and if you will make reference to FMF 76 Minilog our total product line will be clearly presented.

Many of FMF customers are bogged down by the Safety Standard 301 (they currently will not install tanks on vehicles 10,000# or less); and, their attitude is that FMF is responsible for providing a certification basis to them (which of course is not true). Many large manufacturers in the east are providing their dealers (installers) with installation diagrams and stating that a product once installed per their instructions may be certified by the installer. It is highly doubtful that these manufacturers actually performed barrier impact tests, but, rather are relying on the Truck Manufacturers Test Information (Ford, Chev., Etc.), and this information is not available to FMF or to our customers.

It appears to us that by furnishing our customer with a fully representative installation diagram (which would parallel factory procedures), it would provide a clear cut basis to the tank installer to provide a responsible certification. (It should be noted that the installation of an auxilliary gasoline tank does require connecting into existing lines for the supply and vent lines, but it is difficult to see that such additions would in any way create a situation that would be less safe than the vehicle as originally certified by the Truck Factory.

As you probably noted, all of FMF tanks are made to comply with FHWA 393.65 & 393.67; further, the mounting of these tanks has been statically tested far beyond the traditional 5 to 1 safety factor. Our products are in many cases deliberately overdesigned and we do not have product failures. Product failures cannot be tolerated in today's marketplace -- if a company's product liability insurance was every used, it is doubtful that replacement insurance would be available -- even at vastly increased premiums.

Many of our customers are Mom & Pop organizations with up to 10 employees; This type of organization as well as many much larger companies are not able to get involved with extensive testing because of the following reasons; economic, personnel, time and inadequate facilities -- to name just a few.

Since all truck chasses (some with bodies mounted and some without) must be certified by the truck manufacturer -- It would seem reasonable that installers of component parts or auxilliary parts to the truck chassis or body (knowing that their additional certification is to be on that vehicle) will proceed responsibly and especially if fully representative installation diagrams are provided.

Your immediate attention to this letter will be greatly appreciated, & we remain,

Robert I. Fleming, Pres.

TITLE: FMVSR INTERPRETATION

TEXT: This is in response to your letter of May 5, 1977, concerning a vehicle manufacturer's responsibilities with regard to overloading.

You make reference to a November 10, 1976, letter from the National Highway Traffic Safety Administration (NHTSA) which stated that manufacturers must take reasonable steps to ensure that the vehicles they produce will not be overloaded by their users. Although we acknowledge that a manufacturer does not have direct control over the actual use of its vehicles, it does exercise indirect control over use through the vehicle's design.

The NHTSA has stated in the past that a vehicle's gross vehicle weight rating (GVWR) is determined by the sum of its unloaded vehicle weight, 150 pounds for each designated seating position, and its rated cargo load. It is the cargo load rating that is most relevant to the problem of overloading. The rated cargo load should represent the manufacturer's assessment of the vehicle's cargo-carrying capacity and the maximum load at which the vehicle may be safely operated. A manufacturer must consider the maximum load capacity of the vehicle when it designs its cargo-carrying portion. If this is not done, the rated cargo load, and thus the GVWR, may be meaningless since the vehicle may have a cargo-carrying chamber which, if filled, would cause the vehicle to exceed its stated weight ratings. An illustration of such a situation would be a tanker truck which exceeds its GVWR when the tank is filled with a type of material appropriate for carrying in that cargo area. If the manufacturer could reasonably have anticipated that such cargo would be carried in the tanker, yet rated the vehicle with a GVWR which was less than the vehicle's weight when fully loaded with that cargo, a safety-related defect for which the manufacturer is responsible may be considered to exist.

The NHTSA does not expect manufacturers to be omniscient when it comes to the use of the vehicles they produce. It does, however, expect the stated weight ratings to reflect the design of the vehicles and the uses to which they can reasonably be anticipated to be put. Where the manufacturer has reason to know the specific commodity intended to be carried in its vehicles and those vehicles have a totally enclosed cargo area, as with a tanker, the rated cargo load is relatively easy to determine.

In your particular case, your responsibility for any subsequent overloading of the vehicles you manufacture would be determined by the reasonableness of your GVWR's and gross axle weight ratings (GAWR), given the size and configuration of your vehicles and the types of loads which they could reasonably be expected to carry. Since some of your vehicles are flat beds (no enclosed cargo area) you would obviously not be able to provide weight ratings sufficiently high to prevent overloading in all instances. The design of flat beds necessarily permits overloading since the cargo area is unrestricted. Thus if the weight ratings you specify appear to have been arrived at by a good faith determination based upon the types of loads you anticipate will be carried, your responsibility with regard to weight rating specifications will have been satisfied and no safety-related defect will be attributable to you.

Frank Berndt Acting Chief Counsel U.S. Department of Transportation National Highway Traffic Safety Administration

In reference to your letter of November 10, 1976, you made some interpretations which we feel are unreasonable and find that it is impractical to meet compliance.

You indicated that "A vehicle whose axle weight ratings are likely to be exceeded under the manufacturer's intended or reasonably foreseeable conditions of usage would probably be considered to contain a safety related defect." You further stated "The NHTSA expects the vehicle manufacturer to take reasonable steps, short of refraining from production, to minimize the likelihood of vehicle misuse through overloading."

We, as a manufacturer, construct flat platform trailers and van type trailers. When these units are manufactured we certify both a GVWR and GAWR. We however, in most cases, have no way of knowing what products or mix of products will be carried on or in these vehicles.

We do know that most users of this type equipment will carry the maximum allowable payload by State and/or Federal laws. If we construct a vehicle with 10:00 X 20 tires our GAWR will be 19,040# per axle. The present Federal law will allow up to 20,000# per axle and states up to 22,000# per axle. From this we could conclude that many axles could be overloaded as compared to our GAWR. However, we have no real knowledge that this condition does exist but have strong suspicions that it may. We furthermore have no means of controlling how the vehicle is used during its lifetime.

It is definitely unreasonable for NHTSA to expect a vehicle manufacturer to be responsible for the actions and operations of truck lines and other trucking operations.

We feel that placing a specific GVWR and GAWR on the vehicle by the manufacturer is warning enough and that problems of overload is the responsibility of the user and should be controlled by Federal and State weight limits and the Bureau of Motor Carrier Safety.

We have received a copy of your legal interpretation to Mr. Jackson Decker of E. D. Etnyre & Company (copy attached) in regards to GAWR rating and overloading of the same. Excerpts from your interpretation which is of concern to us is:

"A vehicle whose axle weight ratings are likely to be exceeded under the manufacturer's or reasonably forseeable conditions of usage would probably be considered to contain a safety-related defect. Such a vehicle would be subject to the notification and rememdy provisions of the National Traffic and Motor Vehicle Safety Act of 1966, as amended (15 U.S.C. 1392 et seq.).

"We cannot prescribe specific steps that a vehicle manufacturer must take to insure that a GAWR would not be found so low that it would be a safety-related defect. For example, if a warning in the owner's manual against loading in a certain manner is likely to be ignored, then such a warning would not, by itself, be sufficient. The NHTSA expects the vehicle manufacturer to take reasonable steps, short of refraining from production, to minimize the likelihood of vehicle misuse through overloading."

Since we are a manufacturer on several different types of General Purpose vehicles, i.e. Dry Freight Vans, Insulated Vans, Grain Vans, and etc. which can haul a vary of array products, we would like some suggestions on how to eliminate GAWR and GVWR overloading. Obviously, we cannot control what type of commodities or density of commodities that can be "stuffed into a box." Your reasoning on a specific vehicle designed to haul a specific density load is understood, but to insist on a general purpose vehicle manufacturer to control overloading "short of refraining from production" is unreasonable.

Can the auto manufacturers control how many people you haul in your automobile or how much sand you haul in your pickup bed?

Your prompt answer on any suggestions would be appreciated.

Mr. V. J. Adduci Motor Vehicle Manufacturers Association Suite 300 1909 K Street, N.W. Washington, D.C. 20006

Dear Mr. Adduci:

On June 5, representatives of MVMA met with representatives of this agency to discuss various issues concerning the application of Federal Motor Vehicle Safety Standard 115. At that meeting, the MVMA representatives requested clarification of the agency's policy on correction of errors made by vehicle manufacturers in their vehicle identification numbers (VIN's). This letter responds to that request.

The agency shares your concern about the potential difficulties associated with correcting erroneous VIN's and will attempt to minimize the burdens involved with any required corrective action. Nevertheless, the agency must consider the safety benefits of an accurate, national VIN system, as well as the anti-theft and other benefits of such a system.

This letter focuses on some of the most likely VIN errors and discusses whether those errors in vehicles sold to consumers would be inconsequential as the errors relate to safety, and, if not, what type of remedy would have to be provided to vehicle owners. Corrective action involving the replacing of an erroneous VIN plate or label or the restamping of the VIN on part of the vehicle is the most desirable remedy. However, there may be less burdensome remedies that would be effective and satisfy the National Traffic and Motor Vehicle Safety Act.

One type of error which could be easily corrected is an error in a single VIN character other than the check digit or a character monitored by VIN users. The agency would likely regard such an error as inconsequential if the vehicle manufacturer submitted the necessary corrected decoding information to the agency. The agency would place this information in a public file, thereby making it available to other VIN users. With this corrected decoding information available, the agency's safety research activities would not be impaired and manufacturers would still be able to conduct recall campaigns where necessary.

A second type of error involves an erroneous check digit or other character monitored by vehicle records systems of States or other VIN users. Erroneous check digits could adversely affect our ability to conduct research and to monitor recalls, since the error rate of VIN transcription would presumably be higher in the absence of a properly functioning check digit. Further, without some form of corrective action by the manufacturer (such as restamping or the use of a correction label), vehicle purchasers could face rejections by State, insurance, and other data-processing systems using the check digit to verify transcription accuracy. However, the agency is also concerned that the use of labels could create opportunities for auto theft operations to generate bogus VIN's. Therefore, the agency is presently inclined to treat erroneous check digits as inconsequential noncompliance if the manufacturer reports the errors to the agency. However, as discussed below, the agency is planning to invite public comment on this question before establishing a final position on the matter.

A third type of error involves the physical aspects of the VIN itself. For example, a manufacturer might use a type face other than the sans type face required by the standard. Although errors of this type would have to be resolved on a case-by-case basis, they would likely be deemed inconsequential because they would present no problems to the agency, other VIN users, or vehicle owners.

The most difficult type of errors would involve a major error in numbering which would impair the safety and other uses of the VIN. An extreme example of such an error would be a situation where a manufacturer numbered many of its vehicles identically, or where the VIN's were totally illegible. An error of that magnitude could impair the manufacturers' ability to conduct recall campaigns and the ability of the agency to monitor them. It would also cause serious problems for all VIN users. In this type of situation (which should arise rarely, if ever), some form of corrective action would be necessary. The use of a correction label which meets all requirements of FMVSS 115 including indelibility would be one possible approach.

One final matter discussed at the June 5 meeting relates to the correction of VIN errors on vehicles already produced but still in the possession of the manufacturer. We would treat these vehicles the same as the vehicles already sold, i.e., if the noncompliance were inconsequential for the vehicles already sold, it would also be inconsequential for the vehicles produced but still in the manufacturer's possession. However, the agency would expect that once the error is detected, similar vehicles produced thereafter would fully comply with the standard. There is precedent for this approach, since the agency has previously treated as inconsequential noncompliance erroneous identification numbers on tires still in the manufacturer's possession, where an inconsequentiality petition has been granted with respect to tires already sold.

The agency will issue in the near future a notice inviting comment on MVMA's petition to change Standard 115 to a general regulation. In this notice, we will seek comment on the types on corrective action discussed above. If you have any thoughts on other means of making these types of corrections, we would of course be pleased to receive your views.

Sincerely,

Frank Berndt Chief Counsel

TEXT:

This responds to your request for NHTSA's determination that certain former East German military trucks, ZIL model 131, are not motor vehicles, and exempt from the Federal Motor Vehicle Safety Standards (FMVSS). We are unable to make such a determinatio n. As explained below, a ZIL model 131 truck imported into the United States is considered a "motor vehicle" for purposes of the National Traffic and Motor Vehicle Safety Act (Safety Act) (15 U.S.C. 1391 et seq.), and is subject to the FMVSS.

Your letter explained that a client plans to import over 500 ZIL model 131 trucks into the U.S. Apparently, your client plans to modify the trucks in the U.S. to use for nonmilitary purposes. Your client intends to send most of the modified trucks to b uyers in other countries, but plans to sell some of the trucks in the U.S. Your letter states: "... (S)ome ZIL vehicles may be modified to meet DOT/NHTSA and EPA standards in order to satisfy those buyers who require vehicles conforming to those standar ds."

Under the Safety Act, any "motor vehicle," whether new or used, that is imported into the United States for sale in this country must be brought into conformity with all FMVSS that applied at the time of its manufacture. The question that must be answer ed is whether the ZIL 131 trucks, at the time of importation, would be considered "motor vehicles."

"Motor vehicle" is defined at section 102(3) of the Safety Act (15 U.S.C. 1391(3)) as:

(A)ny vehicle driven or drawn by mechanical power manufactured primarily for use on the public streets, roads, and highways, except any vehicle operated exclusively on a rail or rails.

NHTSA has interpreted this language as follows. Vehicles that are equipped with tracks or are otherwise incapable of highway travel are not motor vehicles. Further, vehicles designed and sold only for off-road use (such as airport runway vehicles and u nderground mining devices) are not considered motor vehicles, even though they may be operationally capable of highway travel. Vehicles that have an abnormal body configuration that readily distinguishes them from other highway vehicles and a maximum sp eed of 20 miles per hour (mph) are not considered motor vehicles, because their use of the public roads is intermittent and incidental to their primary intended off-road use.

On the other hand, vehicles that use the public highways on a necessary and recurring basis are motor vehicles. For instance, a utility vehicle like the Jeep is plainly a motor vehicle, even though it is equipped with special features to permit off-road operation. If a vehicle's greatest use will be

off-road, but it will spend a substantial amount of time on-road, NHTSA has interpreted the vehicle to be a "motor vehicle." Further, the agency has determined that a vehicle such as a dune buggy is a motor vehicle if it is readily usable on the public roads and is in fact used on the public roads by a substantial number of owners, regardless of the manufacturer's stated intent regarding the terrain on which the vehicle is to be operated.

Applying the above criteria, and based on the information in your letter, the ZIL model 131 trucks are motor vehicles. You state that potential U.S. buyers would require vehicles that meet the FMVSS. This suggests that U.S. vehicle owners intend to use the ZIL model 131 trucks as they would other motor vehicles, on the public roads. Judging from your photographs, the trucks do not have abnormal body configurations that distinguish them from other vehicles on the road. You stated that the trucks have a top speed of almost 50 miles per hour, a speed suitable for public roads. These facts suggest that the ZIL model 131 truck is designed and intended to be routinely used on the public roads, and should be classified as a motor vehicle.

Assuming your client is still interested in importing the ZIL 131 trucks for resale in the U.S., the Imported Vehicle Safety Compliance Act requires that the agency determine that the vehicles are capable of conversion to meet the FMVSS, and that the tru cks be imported by a "registered importer." The agency makes determinations upon the basis of a petition by the manufacturer or registered importer (or upon its own volition). A "registered importer" is one whom NHTSA has recognized as capable of conve rting vehicles to meet the FMVSS. If you would like further details on eligibility determinations and import procedures, please let us know and we shall be pleased to provide them.

The Safety Act also addresses trucks your client wishes to import into the U.S. for modification for export. Under section 108(b)(3) of the Safety Act, the FMVSSs do not apply to vehicles intended solely for export. Thus, trucks brought into the U.S. f or modification for export are not subject to the FMVSSs. Under 49 CFR S591.5, the importer would file a declaration under S591.5(c), that the vehicle does not comply with all applicable Federal motor vehicle safety, bumper, and theft prevention standar ds, but is intended solely for export.

I hope that this information is helpful. If you have any questions, please contact Dorothy Nakama of my staff at this address or at (202) 366-2992.

TEXT:

This responds to your request for an interpretation of how NHTSA's regulations would apply to some manufacturing operations you are contemplating. I apologize for the delay in this response. In a telephone conversation with Dorothy Nakama of my staff, you explained that you would like to start producing vehicles based on Ford pickup truck chassis. Some of these Ford chassis would come from wrecked vehicles that you would strip down to the frame, and others would be new chassis that you would purchase directly from Ford. You would then install new bodies on top of some of these chassis and offer them for sale as completed vehicles. You also would like to offer some of these bodies and chassis for sale as "kit cars." In the "kit car" version, you would sell the body and chassis to the purchaser of the kit, and the purchaser of the kit would have to furnish some other parts in order to complete the vehicle.

This agency's Federal motor vehicle safety standards apply to new motor vehicles and new items of motor vehicle equipment. Federal law does not require motor vehicles and items of motor vehicle equipment to continue to comply with the safety standards after the first purchase of the vehicle or equipment item in good faith for purposes other than resale. However, Federal law does prohibit any manufacturer, distributor, dealer, or repair business from knowingly "rendering inoperative" compliance with a safety standard for a vehicle or item of equipment. See 15 U.S.C. 1397 (a)(1)(A), (a)(2)(A), and (b)(1).

1. NEW BODY ON NEW CHASSIS. All vehicles you produce by installing a new body on a new chassis would be considered new vehicles. You would have to certify that each of those vehicles conformed to all applicable safety standards. You would be considered a "final stage manufacturer" of the vehicles, as that term is used in 49 CFR Parts 567 and 568.

2. NEW BODY ON USED CHASSIS. We cannot say from the information you have provided whether the vehicles you produce by installing a new body on a stripped, wrecked Ford pickup would be treated as a new vehicle, and have to be certified as complying with the applicable safety standards. The answer depends on how extensively you modify the Ford pickup chassis.

To allow vehicle modifiers to determine when the modifications to a used chassis are so extensive that the resulting vehicle will be considered new for the purposes of the Federal safety standards, NHTSA has established specific criteria at 49 CFR 571.7(e), COMBINING NEW AND USED COMPONENTS. That section reads as follows:

When a new cab is used in the assembly of a truck, the truck will be considered newly manufactured . . . unless the engine, transmission, and drive axle(s) (as a minimum) of the assembled vehicle are not new, and at least two of these components were taken from the same vehicle.

This provision means that if you leave the frame, engine, transmission, and drive axle in place from the wrecked vehicle, and place a new body on top of it, we would consider that vehicle to be a used vehicle, which would not have to be certified by you as complying with applicable safety standards. On the other hand, if you were to remove all the drive components from the frame of the Ford pickup chassis, and add new drive components or rebuilt drive components from different vehicles, the vehicle would be a new vehicle and would have to be certified by you as complying with all applicable safety standards.

3. KIT CARS. Under the National Traffic and Motor Vehicle Safety Act, a "motor vehicle" is defined, in part, as one that is "driven by mechanical power." See 15 U.S.C. 1391(3). We have interpreted this provision to mean that a unit would be considered only an assemblage of motor vehicle equipment, and not a motor vehicle, until such time as a power source is added. None of the Federal motor vehicle safety standards apply to assemblages of motor vehicle equipment, or to used equipment items in the assemblage (items used on a vehicle previously in service on the public roads). However, certain of the safety standards would apply to new equipment items included in the assemblage. It would be a violation of Federal law if your kit car includes any new brake hoses, brake fluid, lighting equipment, tires, glazing, or seat belt assemblies that do not comply with the applicable safety standards.

If you ship your kit cars with all parts needed to produce a completed motor vehicle, including the power source, this agency will treat the kit car as a motor vehicle, not an assemblage of motor vehicle equipment, regardless of the state of completion of the kit. You would be required to certify that the kit car conformed to all applicable safety standards if it were treated as a new vehicle under the rules set forth in 1. and 2. above, but not if it were treated as a used vehicle under those rules.

I have enclosed for your information a general information sheet for manufacturers of new vehicles. This sheet highlights the relevant Federal statutes and regulations and explains how to obtain copies of them. I have also enclosed a brochure titled "Federal Motor Vehicle Safety Standards" that briefly describes each of the safety standards.

I hope this information is useful. If you have any further questions or need further information, please contact Dorothy Nakama of my staff at (202) 366-2992.

TITLE: FMVSR INTERPRETATION

TEXT: Thank you for your letter of October 26, 1972, forwarding the National Tire Dealers & Retreasers Association's (NTDRA) Resolution of October 2, 1972, regarding the Federal Regulation on Tire Identification and Recordkeeping.

The idea of attaching a return card on each tire at the factory to be filled out and returned by the purchaser was given serious consideration during rule making but no practical method was known for attaching a card that would assure retention through delivery to the dealer. Also, the suggestion that the consumer fill out the record card gave no promise of return as far as we could determine from our studies. However, we believe a dealer can be relied upon to record the data in a matter of a few minutes at minimum cost. These factors prevent us from accepting the NTDRA proposal as a reasonable compromise unit would still maintain the needed public interest.

With respect to effectiveness, we believe that the pay-off potential of the regulation, though rather poor in the first year of operation, is continuing to show improvement as time goes on. Although we have no precise count, many tires manufactured prior to May 22, 1971, were in stock and were put on the market during the past 17-month period. As time goes on these pre-regulation tires will gradually disappear from the market and be replaced entirely by the "identified" tires. We would expect that the effectiveness of Part 574 would not reach its full potential until a 3-year period had elapsed.

You may be interested in the following data concerning tire recalls: No. of Tires Recalled NHTSA Voluntary 1970 160,899 28,823 1971 78,050 157,143 1972 (incomplete) 100,000 76,915 338,949 262,881 Grand Total 601,830

These statistics show that almost 45 percent of tire recalls have been initiated on a voluntary basis by the tire manufacturer, and that voluntary recalls during 1971 and 1972 appear to have increased considerably over 1970. Although we have no exact figures on percentage of returns, we take this as an indication that the National Highway Traffic Safety Administration's tire safety program is removing dangerous tires from the road and the system we are using is showing considerable success toward reaching ultimate objectives. We are very much encouraged in the trend of Part 574 toward effectiveness of recalls.

We want to assure you that although the rule making docket reflects exploration of many ideas concerning tire identification and recordkeeping, we are still receptive to any new proposal that would appear promising in improving the present system.

Sincerely,

Enclosure

RESOLUTION

52ND ANNUAL CONVENTION NATIONAL TIRE DEALERS & RETREADERS ASSOCIATION INC. OCTOBER 2, 1972 WHEREAS the National Tire Dealers and Retreaders Association has received a number of complaints from its members on the difficulties of registering the name and address of each purchaser of tires as required by the Tire Identification and Record Keeping Regulation as well as the attendant costs for the retailer without recovery, and;

WHEREAS the National Highway Traffic Safety Administration has failed to provide a uniform form for such records in spite of requests by tire dealers and others in the industry;

WHEREAS some of the recalls that were conducted during nineteen hundred and seventy two have been for tires manufactured prior to the registration requirement of May of nineteen hundred and seventy one;

WHEREAS the burden on the retailer and consumer alike has not been offset by appropriate advantages to the consumer;

NOW THEREFORE BE IT RESOLVED by the National Tire Dealers and Retreaders Association in Annual Convention assembled this second day of October, nineteen hundred and seventy two, that this Association urges the National Highway Traffic Safety Administration to re-examine its current program which requires the seller to register the first purchaser of a new tire and retreaded tire and that it consider a voluntary system of registration by the tire purchaser utilizing an uniform form supplied by tire manufacturers and distributed at the time of sale for the consumer to fill out and mail back to a designated place rather than to leave the entire burden with the individual tire dealer.
