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.

COPYEE: AMERICAN ASSOCIATION OF MOTOR VEHICLE ADMINISTRATION

TITLE: NOA-30

ATTACHMT: LETTER DATED 11/28/80 FROM P. SOARDO TO NHTSA RE REAPPROVAL OF LIGHTING DEVICES, FEDERAL STANDARD 108

TEXT: Dear Professor Soardo:

Your letter of November 28, 1980 has just arrived, in which you asked about State approval of lighting devices.

Each State has its own requirements and method of proceeding, and these are independent of U.S. governmental requirements. Therefore, I regret to say, we are unable to answer this question, and it should be asked of the particular State in which you have an interest. However, the American Association of Motor Vehicle Administration may be able to answer this question and we are sending a copy of your letter to it for direct reply.

You have also asked what Motor Vehicle Safety Standard No. 108 requires "when a car is no longer manufactured, but... lighting devices are available as spare parts". Standard No. 108 applies not only to motor vehicles but also requires compliance of lighting equipment manufactured to replace lighting equipment originally installed on a motor vehicle pursuant to Standard No. 108.

Sincerely,

    Washington, DC 20036-1609

    Dear Mr. Kastner:

    This is in reply to your letter of June 26, 2003, which, to facilitate future reference, is your third request for interpretations relating to the early warning reporting (EWR) regulations issued by this agency (Subpart C, 49 CFR Part 579).

    Your first issue related to an inconsistency that others have brought to our attention, and which we intend to address in a forthcoming Federal Register notice. That is, the regulation requires complete reporting by a manufacturer of light vehicles with an aggregate number of vehicles either during the reporting period or "during each of the prior two calendar years is 500 or more" (49 CFR 579.21) whereas complete reporting is required for medium-heavy vehicles and buses if the aggregate number of vehicles "during either of the prior two calendar years is 500 or more" (49 CFR 579.22; see also Sections 579.23 and 579.24). The regulatory text of the final rule was intended to implement the related statement that we made in the preamble (67 FR 45822 at 45831), that manufacturers of motor vehicles would report under Section 579.27 if their aggregate number of vehicles was fewer than 500 "in the year of the reporting period and in each of the two calendar years preceding the reporting period." Accordingly, we intend to correct Sections 579.22, 579.23, and 579.24 to reflect the intent expressed in our preamble statement.

    Your second request was that the template for manufacturers reporting under Section 579.27 be revised so that the entry column labeled "Deaths/ Injuries" be changed to "Deaths," to reflect the fact that these manufacturers are not required to report injuries. However, your assumption is not correct. Although manufacturers reporting under Section 579.27 need not report incidents involving only injuries, they are required to report the number of injuries of which they are aware that occurred in incidents involving one or more deaths that are identified in claims or notices received by the manufacturer.

    Your third and fourth requests related to the definition of "platform" and issues you believed it may raise with respect to final stage manufacturers.

    The EWR rule defines "platform" as follows:

    Platform means the basic structure of a vehicle, including but not limited to, the majority of the floorpan and undercarriage and elements of the engine compartment. The term includes a structure that a manufacturer designates as a platform. A group of vehicles sharing a common structure or chassis shall be considered to have a common platform regardless of whether such vehicles are of the same type, are of the same make, or are sold by the same manufacturer.

    "Structure," in turn, is defined as follows:

    Structure means any part of a motor vehicle that serves to maintain the shape and size of the vehicle, including the frame, the floorpan, the body, bumpers, doors, tailgate, hatchback, trunk lid, hood and roof. The term also includes all associated mounting elements (such as brackets, fasteners, etc.

    You related that vehicles manufactured in two or more stages can have both common structures on different chassis, as well as different structures on common chassis. You asserted that the "floorpan or undercarriage, and elements of the engine compartment are very rarely, if ever, added or modified by a final stage manufacturer," and you asked whether the designation of "platform" for the final stage manufacturer should "be derived from the body/equipment being added to complete the vehicle or from the original chassis."

    The definition of platform includes a group of vehicles "sharing a common structure or chassis." We construe the regulatory definition to mean that vehicles with "different structures on common chassis" have the same platform. We recognize that the regulatory language could be construed such that vehicles that have common structures added by a final stage manufacturer on different chassis could also be considered to have the same platform. However, that was not our intent. Moreover, such an interpretation could lead to confusion, since, under that approach, some vehicles could be considered to have more than one platform.

    Your fourth concern relates to vehicles that share a platform because they are built on a common chassis. You asked how an incomplete vehicle manufacturer would determine which models share the same chassis since this is "typically an internal designation assigned by the incomplete vehicle manufacturer."It is our understanding that chassis manufacturers use well-established and recognized designations for their chassis, such as Ford "E Series" or General Motors "C/K Series."Moreover, platform designations by final stage manufacturers do not have to be exactly the same as those of the original chassis manufacturer. Rather, final stage manufacturers need only identify those models/vehicles that share a chassis.

    Finally, you asked whether the platform designations would be "determined the same way for alterers as for final stage manufacturers?"The answer is yes.

    If you have any additional questions, you may refer them to Andrew DiMarsico of this office (202-366-5263).

    Robert A. Rybak, Associate Attorney
    Office of Legal Affairs
    State of New York
    Department of Transportation
    50 Wolf Road
    Albany, NY12232


    Dear Mr. Rybak:

    This is in response to your letter and June13, 2005, facsimile asking whether the proposed changes to the New York State Department of Transportation (NYSDOT) bus inspection procedures are preempted by Federal regulations. We apologize for the delay in responding, as your original correspondence was lost. In short, we conclude that except for certain limited circumstances, the proposed procedures would not be preempted by Federal regulations.

    In your letter, you explain that the new inspection procedures would require aftermarket bus modifiers to provide certain documentation and certification as to the scope of the changes made to a modified bus. Specifically, if the certification label required by 49 CFR Part 567 is missing, or contains information that no longer accurately reflects the vehicle because of the extent of modifications, the new procedures would require the modifiers to provide "Certification of the Present Status of Vehicles Altered, Modified, or Remanufactured After First Sale".

    By way of background, the National Highway Traffic Safety Administration (NHTSA) issues Federal motor vehicle safety standards (FMVSSs) applicable to new motor vehicles and motor vehicle equipment. Chapter 301 of Title 49 of the United States Code, "Motor Vehicle Safety" (49 U.S.C. 30101 et seq.), establishes a "self-certification" process under which all motor vehicle manufacturers, including bus manufacturers, are responsible for certifying that their vehicles meet all applicable FMVSSs. The certification label requirements are listed in 49 CFR Part 567. 567.4(g)(7) specifies that the certification label must indicate the type of the vehicle being certified (e.g., truck, bus, trailer).

    With respect to your question, we first note that NHTSA does not generally regulate rebuilding or re-manufacturing of used motor vehicles, and thus, the States are not preempted from regulating these activities. However, if the rebuilding or remanufacturing involves sufficient manufacturing operations and new parts, the vehicle may be considered newly manufactured. This means that it would be required to meet all applicable safety standards in effect at the time of rebuilding (re-manufacture), and to be certified as conforming to those standards. Because of the variety of fact situations involved, the agency has found it difficult to establish a general requirement, and it provides opinions on a case-by-case basis.

    We note that the preemption issue arises only with respect to the proposed NYSDOT requirements of certification. The States are not, of course, preempted from conducting inspections of all vehicles in question. We further note that, if a modified vehicle does not fall into the category of being deemed newly manufactured, the only other Federal requirement that is imposed on commercial entities that make modifications to used vehicles is that they "not knowingly make inoperative any part of a device or element of design installed on or in [the] vehicle . . . in compliance with an applicable motor vehicle safety standard . . ." (49 U.S.C. 30122(b)).

    Finally, please be advised that on June 22, 2005, we published a notice of proposed rulemaking proposing to amend the definition of "designated seating position" (70 FR 36094). If this proposal is adopted, it may affect your procedures with respect to determining seating capacity.

    I hope you find this information helpful. If you have further questions, you may contact Mr. George Feygin of my staff at (202) 366-2992.

    Albany, NY 12228



    Dear Mr. Wagar:

    This responds to your letter and telephone calls asking whether a proposed New York State bill (A00359) would be preempted by Federal law, in light of a possible inconsistency with Federal Motor Vehicle Safety Standard (FMVSS) No. 205. I regret the delay in responding. Your correspondence attached a version of the bill and expressed concern regarding an amendment to the original language of the bill which imposes light transmittance requirements on windows to the left and right of the driver on sport utility vehicles (SUVs) and other multipurpose passenger vehicles (MPVs). Based on our understanding of your correspondence and telephone conversations with staff, we believe that the legislation would not be preempted.

    BACKGROUND

      According to your correspondence, New York's amended proposed law states, in relevant part:

      (b) No person shall operate any motor vehicle upon any public highway, road or street:

      * * *

      (4) the rear window of which is composed of, covered by or treated with any material which has a light transmittance of less than seventy percent. A rear window may have a light transmittance of less than seventy percent if the vehicle is equipped with side mirrors on both sides of the vehicle so adjusted that the driver thereof shall have a clear and full view of the road and condition of traffic behind such vehicle.

    The proposed State law pertains to the light transmittance of the rear window of SUVs and other MPVs, which is an aspect of performance regulated by Federal Motor Vehicle Safety Standard No. 205, Glazing Materials (49 CFR '571.205). The standard specifies performance requirements and permissible locations for the types of glazing that may be installed in motor vehicles. The standard requires some glazing to allow 70 percent of the incident light to pass through. For buses, trucks, and multipurpose passenger vehicles (MPV's), the standard specifies the 70 percent light transmittance requirement for glazing installed in the windshield, the windows to the immediate left and right of the driver, and any rear window that is used for driving visibility.

    The proposed State standard also pertains to the requirements of Federal Motor Vehicle Safety Standard No. 111, Rearview Mirrors (49 CFR '571.111). The standard at S6.1 requires that MPVs, trucks and buses with a GVWR of 4,536 kg or less must have either (a) a passenger car mirror system, which includes an inside rear view mirror; or (b) a light truck mirror system, which requires unit magnification (flat) outside rear view mirrors of a minimum size on each side of the vehicle. In vehicles using the passenger car mirror system, the rear window is used for visibility. An inside mirror is not required for use with the light truck mirror system.

    Whether the proposed New York law would be preempted under our statute is determined by '30103(b) of 49 U.S.C. Chapter 301, which states in part:

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

    NHTSA safety standards apply to the manufacture and sale of new motor vehicles and motor vehicle equipment. (49 U.S.C. 30112.) Thus, pursuant to 49 U.S.C. 30103(b), state laws that apply to the manufacture and sale of new vehicles, and to the same aspect of performance, must be identical to the FMVSS.

    However, NHTSA does not regulate the operation (i.e., use) of motor vehicles, which is generally under the jurisdiction of the States. Federal law does not require New York to set operational requirements that are "identical" to the FMVSS. Nonetheless, there are limits on State operational requirements, in that general principles of preemption law apply. These principles preclude States from adopting operational requirements that are more stringent than the requirements applicable to new vehicles under the FMVSS, because more stringent State requirements would have the effect of precluding the use of a Federally compliant vehicle in that State.

    ANALYSIS

    The proposed New York law would appear to be more stringent than the FMVSS, in that it would prohibit the windows to the rear of the driver on the left and right from having a light transmittance of less than 70 percent. However, NHTSA has determined in a 1998 rulemaking that the light transmittance levels of light truck and MPV rear glazing not used for driving visibility and light truck and MPV rear side glazing are not regulated under FMVSS No. 205, and that States are therefore free to set transmittance levels for those windows on those vehicles. Withdrawal of notice of proposed rulemaking, July 14, 1998, 63 FR 37820. Thus, we conclude that the proposed New York law would not be preempted and that New York could prohibit the operation of light trucks and MPVs with rear windows that have a minimum light transmittance of less than 70 percent.

    In addition, the proposed New York law would be less stringent than the FMVSS for mirrors because the New York law merely requires two outside mirrors rather than mirrors complying with the light truck mirror system in S6.1(b) of FMVSS No. 111. Therefore, we conclude that the proposed New York law would not be preempted under '30103(b).

    If you have any further questions, please feel free to contact Nancy Bell of my staff at this address or by telephone at (202) 366-2992.

    New York State Department of Transportation
    Office of Legal Affairs
    Building 5, New York State Campus
    Albany, NY 12232



    Dear Mr. Perreaut:



    This responds to your letter and telephone calls asking whether a New York state bill (S.1731-B, January 27,1999,) would be preempted by Federal law, in light of a possible inconsistency with Federal Motor Vehicle Safety Standard No. 111, "Rearview Mirrors." Your correspondence attaches a revised version of the bill and a letter dated April 16, 1999, from the Federal Highway Administration (FHWA) to your office regarding a previous version of the bill. Further, you attach a copy of a request for comments, dated June 12, 1996, based upon a granted petition for rulemaking to the National Highway Traffic Safety Administration (NHTSA) to require convex cross view mirrors on certain trucks (61 FR 30586). Based on our understanding of your correspondence and telephone calls, we believe that the answer to your question is a qualified no.

    According to your correspondence, New York's proposed law states, in relevant part:

      Every motor vehicle when driven or operated upon a public highway in the delivery of goods or services to residential or business locations shall be equipped with one or more cross-view back-up mirrors designed to allow the driver of such motor vehicle a view of the area behind the back of the motor vehicle.

    For the purposes of the bill, a "motor vehicle" is defined as:

      a vehicle that is registered or based in the state of New York, and that is equipped with a cube-style or enclosed delivery bay with a minimum eight feet six inches and a maximum of eighteen feet, provided that any such vehicle be a single unit vehicle which is operated for commercial purposes except for motor vehicles in interstate commerce and rental vehicles....

    A "cross-view back-up mirror" is defined as "a mirror mounted on a motor vehicle and so located to enable the driver to view directly behind such vehicle."

    Section 30103(b) of our statute, 49 U.S.C. 30103(b) (formerly 103(d) of the National Traffic and Motor Vehicle Safety Act), states in part:

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

    Federal Motor Vehicle Safety Standard No. 111, Rearview Mirrors (49 CFR 571.111), requires side rear view mirrors on trucks with a gross vehicle weight rating (GVWR) of 4,536 kilograms (kg) or more. The standard at S7.1 (for trucks with GVWRs of between 4,536 kg and 11,340 kg) and at S8.1 (for trucks with GVWRs of 11,340 kg or more) requires mirrors on both sides of the vehicle. The mirrors must be "located so as to provide the driver a view to the rear along both sides of the vehicle and shall be adjustable both in the horizontal and vertical directions to view the rearward scene." The use of the words "a view to the rear" and "rearward scene" does not indicate that the specified field of view extends directly behind the truck. Our review of the rulemaking history of the standard, including the notice we published at 61 FR 30856 (June 12, 1996), indicates that there is no Federal intent to regulate the area directly and immediately behind the type of vehicle in question. New York would thus be regulating a different aspect of performance (i.e., a different field of view) than that regulated by Standard No. 111.

    If the State regulation addresses only the area directly behind the motor vehicle and therefore not the area addressed by Standard No. 111, it would not be preempted by 30103(b). However, it is difficult to respond categorically that the State regulation would not be preempted because you have provided little information on what the State would require. The State regulation would be preempted if it conflicts with Federal law, either by creating a situation in which manufacturers cannot comply with both the State and Federal laws, or by interfering in some way with another Federal motor vehicle safety standard (such as the field-of-view requirements for the lighting standard, 49 CFR 571.108).

    If NHTSA were to issue a standard regulating the field of view of this area, inconsistent State laws would be preempted to the extent that they are not identical with the Federal standard. Of course, we would consider any relevant State laws when adopting a Federal standard. Currently, we have ongoing rulemaking considering establishing performance for rear cross view mirrors. We expect to publish an Advanced Notice of Proposed Rulemaking (ANPRM), following upon 61 FR 30586, on this in the future.

    In addition, there may be preemption issues concerning Federal law administered by the Department's Federal Motor Carrier Safety Administration (FMCSA), which has jurisdiction over interstate motor carriers operating in the United States. FMCSA was established on

    January 1, 2000, and was formerly a part of the Federal Highway Administration (FHWA). We note that Mr. Brian Temperine of the FHWA wrote your department on April 16, 1999, concerning preemption issues arising from a previous version of the bill in question. We suggest that you contact the FMCSA at (202) 366-4012 for information concerning preemption, FHWA's April 16, 1999, letter, and FMCSA's views of the current version of the bill.

    In closing, we want to make clear that we are not providing any views with respect to the merits of the State mirror requirement to be enacted in New York. This letter only addresses the preemption issue you raised.

    If you have any further questions, please feel free to contact Nancy Bell of my staff at this address or by telephone at (202) 366-2992.

    Department of Motor Vehicles

    Albany, NY 12228


    Dear Ms. Traschen:

    This responds to your letter in which you asked whether New York State "must" amend its definition of low speed vehicle (LSV) to conform to the recent amendment to the Federal definition of LSV. Your question is addressed below.

    The National Highway Traffic Safety Administration established Federal Motor Vehicle Safety Standard (FMVSS) No. 500, Low Speed Vehicles, to ensure that LSVs are equipped with an appropriate level of motor vehicle equipment for the purposes of safety. As established in an August 17, 2005 final rule, LSV is defined as a 4-wheeled motor vehicle with a maximum gross vehicle weight rating less than 1,134 kilograms (2,500 pounds), whose attainable speed in one mile is more than 32 kilometers per hour (km/h) (20 miles per hour (mph)) but less than 40 km/h (25 mph) (70 FR 48313).

    In your letter, you stated that the definition of LSV under New York State Vehicle Traffic and Safety Law 121-f does not include a gross vehicle weight rating limit. You then asked if New York State must amend its definition of LSV to conform to the recently amended Federal definition of LSV.

    While a State is not required to amend its definition of LSV, maintaining a different definition than the Federal definition could have implications with respect to preemption of State laws.

    Under Federal law, a vehicle that meets the Federal definition of "low-speed vehicle" must be manufactured to conform to FMVSS No. 500. Similarly, a vehicle that meets the Federal definition of "passenger car," "multipurpose passenger vehicle," or "truck," must be manufactured to meet the FMVSSs applicable to that vehicle type, regardless of how the vehicle may be classified under State law.

    Under 49 U.S.C. 30103(b), when a Federal motor vehicle safety standard is in effect, a State or a political subdivision of a State may prescribe or continue in effect a standard applicable to the same aspect of performance of a motor vehicle or motor vehicle equipment only if the standard is identical to the standard prescribed under this chapter.

    Different motor vehicle safety standards apply depending on how a vehicle is classified, i.e. , its vehicle type. If a State law classifies a vehicle differently than Federal law, preemption is an issue under 49 U.S.C. 30103(b) if: (1) the State classification results in the vehicle being subject to a State standard applicable to the same aspect of performance regulated by a FMVSS, and (2) the State standard is not identical to the FMVSS. In such an instance, the State safety standard would be preempted.

    If you have any further questions, please contact Mr. Calamita at (202) 366-2992.

Mr. Brian Lambert

Humble, TX 77338

Dear Mr. Lambert:

This responds to your letter asking whether several models of scooters you are considering importing into the United States are "motor vehicles" for the purpose of the regulations administered by the National Highway Traffic Safety Administration (NHTSA). As explained below, it is our opinion that the two models with a maximum speed greater than 20 mph are motor vehicles.

The legislation establishing NHTSAs vehicle safety authority is set out at 49 U.S.C. Chapter 301. Under 49 U.S.C. 30112, a person may not import into the United States, "any motor vehicle or motor vehicle equipment manufactured on or after the date an applicable motor vehicle safety standard prescribed under this chapter takes effect unless the vehicle or equipment complies with the standard[.]" (Emphasis added.) "Motor vehicle" is defined at 49 U.S.C. 30102(a) as:

[A] vehicle driven or drawn by mechanical power and manufactured primarily for use on the public streets, roads, and highways, but does not include a vehicle operated only on a rail line.

In a November 26, 2003, letter addressed to Mr. Amir Ambar, we addressed the issue of whether a scooter that he wished to import into the United States was considered a motor vehicle under this definition. We will consider the points we made in that letter in responding to your request.

In responding to Mr. Ambar, we noted that when determining if a vehicle is manufactured primarily for use on the public streets, roads and highways, the agency first looks to see if the vehicle has on-road capabilities.

We also noted that in an October 3, 1969, notice, the agency determined that while "mini-bikes" have on-road operating capabilities, they are not motor vehicles for

the purpose of our standards (34 Federal Register 15416; enclosed). At that time the agency found that "mini-bikes" were precluded from operation on public roads by a vast majority of States. The agency has determined this to still hold true. Further, "mini-bikes" were at that time promoted and advertised solely for off-road use.

The scooter at issue in our November 2003 letter was described as a "toy" intended for off-road use only. The literature submitted stated that the maximum speed of the scooter ranged between 12.5 and 16 miles per hour (mph). The scooter was shown to have an engine displacement of 36 cc, a height of 33 inches, and wheel diameters of ten and nine inches (front and rear, respectively). The owners manual and a label on the scooter warned against operating the scooter on public roads.

Based on the description provided, including its speed capabilities and small size, we concluded that the "scooter" at issue was properly characterized as a "mini-bike," and therefore was not a "motor vehicle" within the meaning of Chapter 301. We explained that the scooters low speed capability would prohibit it from being operated in normal moving traffic. This was reflected in the warning label. Further, the low sitting height and small wheel diameters were comparable if not smaller than those of the mini-bikes considered under the 1969 notice.

We also stated that while the scooter at issue in that letter could theoretically be operated on public roads, we anticipated that because of its small size and absence of a Vehicle Identification Number (VIN), which is generally required by States for vehicles authorized to operate on public roads, incidents of its actual operation on public streets, roads, and highways would be comparatively rare. We recognized that the scooter was equipped with a headlight, horn, turn signals, and a mirror. We noted that while this equipment may be seen as equipping the scooter for road use, such equipment is also sometimes present on bicycles and other non-motor vehicles as well.

Finally, we stated that while we had concluded at that time that the scooter was not a motor vehicle, we might re-evaluate our determination if we were to receive additional information indicating that the scooter (or similar ones) were being used on public roads on more than an incidental basis, the scooter were to be advertised for use on public roads, or the characteristics of the imported scooters were not consistent with the descriptions provided.

We will now turn to the scooters you asked about. In your e-mail, you stated that the three scooter models you are considering importing are intended for off-road-use only. The JC 50 model is advertised as having an engine displacement of 49 cc, a maximum speed of 15 mph, and a height of 32.6 inches. The JC 70 model is advertised as having an engine displacement of 72 cc, a maximum speed of 37 mph, and a height of 37.4 inches. The JC 90 model is advertised as having an engine displacement of 85.7 cc, a maximum speed of 50 mph, and a height of 37.4 inches. Your e-mail stated that all three models are marked for off-road use and all three models have VINs. You further stated that sales of these scooters would be primarily through the internet. As advertised on the internet, the scooters are shown with headlights and mirrors.

Memorandum Regarding Estimates Of Production
Under The Early Warning Reporting Rules

    NHTSA has received inquiries whether under the early warning reporting (EWR) rule, a manufacturer must estimate annual production of its vehicles to determine whether it likely will be above the production threshold for full reporting, and if so, whether it must then submit quarterly reports before its actual production-to-date reaches the threshold. We have also received inquiries on how to report production where the manufacturer does not know, and cannot determine with reasonable effort, the number of reportable items it manufactured.

    The early warning reporting rule divides manufacturers of motor vehicles into two groups with different responsibilities for reporting. The first group, which includes larger manufacturers of motor vehicles that produce, import, offer for sale or sell 500 or more vehicles per year of one or more of four defined categories of vehicles, is subject to comprehensive reporting. See 49 CFR 579.21-24. The second group, which includes relatively small manufacturers of less than 500 vehicles per year in those defined categories, is subject to limited reporting. See 49 CFR 579.27. (Manufacturers of tires and child restraint systems are also required to make comprehensive reports.) As we explained in an interpretation, manufacturers are required to make good faith estimates of their expected annual production for purposes of determining whether to report under 49 CFR 579.21-24 or 579.27. See Letter of July 24, 2003, to Mr. Lance Tunick.

    While we require estimation of future production for purposes of determining whether the manufacturer is likely to be at or above the 500 vehicle threshold, ordinarily reports of production-to-date will be actual numbers. However, manufacturers will be permitted to approximate production information in those situations where it is not possible for a manufacturer to quantify the number of vehicles, tires, or child restraint systems it manufactured. We anticipate and expect that such approximations of past production will be few and far between, given that manufacturers would usually keep production records in the ordinary course of their business.

    Additional questions concerning EWR should be directed to Andrew DiMarsico of this office at 202-366-5263.

    Sr. Vice President, Government Affairs
    Rubber Manufacturers Association
    1400 K Street, NW
    Washington, DC 20005

    Dear Ms. Wilson:

    This responds to your request for an interpretation of the National Highway Traffic Safety Administrations (NHTSA) tire information regulation, 49 CFR 574.7. You asked whether the regulation permits tire manufacturers to offer electronic registration in addition to the required mail-in form. You state that no more than 10% of tire registration cards are currently returned to manufacturers and that the information provided on these cards is often inaccurate, incomplete, or illegible. RMA believes that offering registration via the Internet, by telephone, or by other electronic means would improve the registration return rate and aid manufacturers in fulfilling notification requirements.

    As explained below, we interpret the regulation to permit electronic registration as a supplement to the required mail-in form for independent distributors and dealers.

    By way of background, Part 574 establishes a registration program for new tires. NHTSA implemented this program to improve the effectiveness of manufacturer campaigns to recall tires that contain a safety-related defect or fail to conform with applicable safety standards. By identifying new tire purchasers, the program increases the manufacturers ability to inform owners of tires about defects or noncompliances in those tires.

    Part 574 establishes the following requirements:

    New Tire manufacturers, new tire brand name owners. Except as noted, new registration forms are to be provided for independent dealers. All of those forms are required to be identical in format and content and within the size range specified in the interim final rule. Alternatively, the manufacturer can provide independent dealers with pre-addressed envelopes in which tire purchasers could mail the mandatory registration forms.

    Independent distributors and dealers. These dealers are required to record the tire identification number(s) of the tire(s) sold along with their name and address on a registration form and give the form to the tire purchaser.

    Other distributors and dealers. They must record the purchaser's name and address, the tire identification number(s) of the tire(s) sold, and a suitable identification of themselves as the selling dealer on a tire registration form and return the completed forms to the tire manufacturers or their designees.

    Section 574.7 prescribes the content and format of the registration forms provided by tire manufacturers to all distributors and dealers. Paragraph (a)(2) of this section states that the registration form provided to independent distributors and dealers must conform to the examples provided in that section. Paragraph (a)(4) of this section provides that the registration form must contain space for recording the following information: 1) name and address of the tire purchaser, 2) tire identification number, and 3) name and address of the tire seller or other means by which the tire manufacturer can identify the tire seller. Under section 574.7, no other information than that prescribed in the section is permitted to appear on the form.

    RMA asks that we interpret the regulation to permit manufacturers to provide independent dealers and distributors with a supplemental form, in addition to the form required under section 574.7(a)(2), that notifies consumers that they may also register their tires by electronic means; e.g., by directing the consumer to a website or a toll-free telephone registration line. RMA cites to two recent interpretation letters issued by our office with respect to the electronic registration of child restraint systems under FMVSS No. 213, Child Restraint Systems (letter to John K. Stipancich, January 3, 2003; letter to Mark A. Rosenbaum, Esq., April 12, 2001). These letters conclude that child restraint manufacturers "may include a supplemental form that encourages electronic registration" if the following two conditions are met:

    1. The registration card required by FMVSS No. 213 does not bear any information or writing beyond that required to be on the form, and
    2. The additional information is presented in a manner not likely to confuse consumers about the purpose of the required form or to obscure the importance of owner registration.

    Subsequent to RMAs interpretation request, Computerized Information Management Services, Inc. ("CIMS"), a tire registration agent for tire manufacturers and/or brand name owners, submitted a letter dated April 23, 2003, urging that "web-based tire registration is a bad idea" and that the interpretation that RMA is requesting should be denied. More specifically, CIMS argues that a web-based system would create significant confusion for the tire dealer and the consumer, would place an additional paperwork burden on the tire dealer, and would place an additional burden on the consumer to correctly enter all of the required tire registration information.

    After considering the issues raised by your letter and also by CIMS, we agree that the rationales of the aforementioned FMVSS No. 213 interpretation letters are also applicable to interpreting Part 574. We therefore interpret Part 574 to permit electronic registration as a supplement to the required mail-in form, subject to the two considerations noted above for FMVSS No. 213. We do not agree with CIMS that supplemental electronic registration would create confusion, given these considerations. Moreover, since electronic registration would be supplemental and voluntary, it would not result in additional burdens.

    This interpretation does not relieve non-independent distributors and dealers from the requirements of section 574.8(b) that they themselves record the purchaser's name and address, the tire identification number(s) of the tire(s) sold, and a suitable identification of themselves as the selling dealer on a tire registration form and return the completed forms to the tire manufacturers or their designees. While we would interpret Part 574 to permit non-independent distributors and dealers to accomplish these tasks by electronic means, they may not transfer this responsibility to consumers.

    If you have any questions or need additional information, feel free to contact Nancy Bell of my staff at (202) 366-2992.

    Product Safety Manager
    Oshkosh Truck Corporation
    2307 Oregon Street
    P.O. Box 2566
    Oshkosh, Washington 54903-2566

    Dear Mr. Peterson:

    This responds to your letter of September 22, 2003, requesting confirmation of Oshkosh Truck Corporations (Oshkosh) understanding of its early warning reporting (EWR) responsibilities under the TREAD Act and 49 CFR Part 579 with regard to the military and civilian heavy trucks it manufactures. Your letter provided information concerning three categories of heavy vehicles, one of which was divided into two subcategories: one subcategory for vehicles restricted to off-road use, and one subcategory for vehicles used on public streets and highways. My responses are organized according to the categories you identified.

    The first category you referenced concerned trucks built exclusively for military use with no civilian counterparts. As to this category, I confirm that your understanding is correct that such trucks, designed and manufactured exclusively for military use, and with no civilian counterparts, are not subject to the EWR requirements.See letter of May 21, 2003, to Stewart & Stevenson.

    The second category you referenced concerned Airport Rescue and Firefighting (ARFF) trucks and snow removal trucks. These trucks were, in turn, broken into two subcategories. The first, you explained, includes ARFF and snow removal equipment used exclusively for off-road service and almost exclusively at airports to perform such tasks as fighting airplane fires and removing snow. You stated that it is Oshkoshs understanding that it has no EWR responsibilities for such vehicles in light of their off-road use. The second, you explained, includes snow removal trucks used in on-road service to clear public roads. You stated that it is Oshkoshs understanding that it must report EWR information on these trucks because they are civilian vehicles engaged in on-road work.

    Oshkoshs understanding as to both subcategories of trucks is correct, based on the descriptions that you provided. As to the first subcategory, we have previously interpreted the term "motor vehicle" to exclude vehicles designed and sold solely for off-road use, and have referenced airport runway vehicles as one example of such vehicles.See letter of June 12, 1995, to Mr. Andrew Grubb. By contrast, the snow removal trucks conducting on-road work would be considered motor vehicles for EWR purposes.

    The third category you referenced included trucks designed for and used in the on-road civilian market. You gave an example of concrete placement trucks and stated Oshkosh builds approximately 700 of these trucks each year. You explained that it was Oshkoshs understanding that it would have EWR responsibilities for these trucks because they are civilian and engaged in on-road work. I confirm that your understanding is correct.

    We also note that, based on the annual production information provided in your letter, Oshkosh must submit quarterly EWR information for the two categories of heavy trucks covered by the EWR regulation, as required by 49 CFR 579.22. More specifically, the determinant between full and limited reporting (i.e., as small volume manufacturer under Section 579.27) is the total aggregate production for each reporting category of vehicle defined by the EWR regulation. See letter of August 20, 2003, to Mr. Rod Nash. In this case, it appears Oshkosh produces an estimated 950 medium-heavy vehicles per year, and therefore qualifies as a larger volume manufacturer of medium-heavy vehicles under Section 579.22.

    If you have any further questions, please contact Andrew DiMarsico of this Office (202-366-5263).
