ATTACHMT: ATTACHED TO 3/6/95 LETTER FROM TERRY M. HABSHEY TO PHILIP RECHT (OCC 10785)

TEXT: Dear Mr. Habshey:

This responds to your March 6, 1995 letter to Philip Recht, our former Chief Counsel, and your telephone conversations with Walter Myers of my staff in which you requested a "new D.O.T. number." As discussed below, we are unable to provide you a tire man ufacturer's identification mark since the operations you perform on tires are not sufficient to make you the manufacturer of the tires.

You explained that your company is a global exporter of tires, particularly to third world countries, but that you intend to distribute tires domestically in the future. You stated that you obtain new tires from different manufacturers consisting of ori ginal equipment overruns, blems, etc., and that by a new process you intend to remove "most" of the information from the tire sidewalls. The new process includes removing a thin layer of rubber from the tire sidewall, then vulcanizing a layer of new rubb er onto the sidewall. The new layer will contain a new "registered" trade name, logo, and "identifying marks along with the size, safety information, mounting instructions, maximum and minimum inflating instructions, etc." You emphasized that all tires will be new and meet "all minimum standards established by the Department of Transportation."

Before addressing your request, let me first provide some background information. Chapter 301 of Title 49, U.S. Code (hereinafter Safety Act), authorizes the National Highway Traffic Safety Administration (NHTSA) to issue Federal motor vehicle safety st andards (FMVSS) applicable to new motor vehicles and new items of motor vehicle equipment sold in or imported into the United States. Tires are considered motor vehicle equipment. The Safety Act establishes a self-certification system in which manufact urers certify that their products comply with all applicable FMVSSs effective on the date of manufacture. In the case of tires, manufacturers reflect that certification by molding the letters "DOT" into or onto the sidewalls of all their tires manufactu red for sale in the United States.

The FMVSSs are not applicable to tires intended solely for export, labeled for export on the tires and on the outside of the container, and exported. See 49 U.S.C. @ 30112(b)(3); 49 Code of Federal Regulations (CFR) 571.7(d)). Accordingly, you are free to export any tires you want, whether or not they comply with the FMVSSs and after whatever modifications you make to them.

That is not the case, however, with tires distributed for sale in the United States. FMVSS No. 109, New pneumatic tires and FMVSS No. 110, Tire selection and rims, specify performance standards and labeling requirements for new passenger car tires and r ims. FMVSS No. 119, New pneumatic tires for vehicles other than passenger cars and FMVSS No. 120, Tire selection and rims for motor vehicles other than passenger cars, specify performance standards and labeling requirements applicable to tires and rims for vehicles other than passenger cars. 49 CFR Part 574, Tire identification and recordkeeping, requires new tire manufacturers to permanently mold into or onto one tire sidewall a tire identification number (TIN) and specifies methods by which new tire manufacturers and new tire brand name owners shall maintain records of tire purchasers. 49 CFR Part 575.104, Uniform tire quality grading standards (UTQGS), requires new motor vehicle and new tire manufacturers and brand name owners to provide informat ion to consumers concerning the relative performance of passenger car tires in the areas of treadwear, traction, and temperature resistance. The UTQGS grades are also required to be molded into or onto the tire sidewall.

The labeling requirements specified in the regulations referred to above apply to the actual tire manufacturers and/or brand name owners, and the required information, including the DOT symbol and the TIN, must appear on all new tires before they can be sold to their first retail purchasers. A tire distributor or dealer cannot legally remove any of the required information from new tire sidewalls. The required information on new tires is intended for safety purposes, purchaser information, and to enab le this agency to identify the manufacturer in the event of a noncompliance or defect in a tire line or lot.

A "manufacturer" is defined in 49 U.S.C. @ 30102(a)(5) as one who manufactures or assembles motor vehicles or equipment or one who imports motor vehicles or equipment for resale. The operations you describe would not be sufficient to make you the manufa cturer of the tires in question. According to your letter, you would, for marketing reasons, remove a thin layer of the surface area of the sidewalls of the tires so that most of the existing information is removed. You would then apply a new thin laye r of rubber containing new information. Your operations would thus not be changing the basic tire as such but simply changing the labeling. A change in labeling would not change who manufactured the tire. Thus, since you would not be a manufacturer of tires, you may not obtain a manufacturer's identification mark in accordance with 49 CFR @ 574.6. Only tire manufacturers or retreaders may obtain that mark.

49 U.S.C. @ 30122(b) prohibits manufacturers, distributors, dealers, and/or motor vehicle repair businesses from knowingly making inoperative any part of a device or element of design installed on or in a motor vehicle or item of equipment in compliance with applicable FMVSSs unless that individual reasonably believes that the vehicle or equipment will not be used when the device or element is inoperative. Thus, removal of the labeling information required to be marked on tire sidewalls in accordance w ith the standards and regulations discussed above could be a violation of @ 30122(b), which could subject the violator to civil penalties of up to $ 1000 per violation, or up to $ 800,000 for a series of related violations.

In summary, the Safety Act does not apply to tires intended solely for export. Thus, those tires are not required to comply with any FMVSSs. However, all new or retreaded tires sold or imported into the United States for sale must comply with all applic able FMVSSs and regulations as discussed above. Distributors and dealers may not remove any of the labeling information required to be marked on new tires by the actual manufacturers and/or brand name owners of those tires. Removal of that information c ould make inoperative an element of design on those tires, which could constitute a violation of 49 U.S.C. @ 30122(b).

I hope this information is helpful to you. Should you need additional information or have further questions, please feel free to contact Mr. Myers at this address or at (202) 366-2992.

TITLE: None

ATTACHMT: Attached to letter dated 5/6/92 from Kevin B. Brown to NHTSA (OCC-7323)

TEXT:

This responds to your letter concerning 49 CFR 567 requirements for intermediate or final stage manufacture vehicle labeling. I apologize for the delay in responding. You stated in your letter that EG&G Idaho, as prime contractor for the Department of Energy, Idaho Field Office, procures and maintains all government-owned vehicles, and occasionally procures truck chassis purchased through the General Services Administration for subsequent mounting of service bodies.

I am pleased to have this opportunity to explain our regulations to you. Before addressing the specific issues raised in the letter, some background information may be helpful. The National Traffic and Motor Vehicle Safety Act of 1966, as amended, 15 U.S.C., S1381-1431 (hereinafter "Safety Act") authorizes this agency to establish Federal motor vehicle safety standards for new motor vehicles and items of motor vehicle equipment. NHTSA, however, does not approve motor vehicles or motor vehicle equipment. Rather, the Safety Act establishes a self-certification process which requires each manufacturer, in the exercise of due care, to ensure and certify that its products meet all applicable Federal safety standards. Thereafter, NHTSA periodically tests vehicles and equipment for compliance with the standards and investigates allegations of safety-related defects.

In addition, the Safety Act only requires new vehicles to comply with applicable safety standards. The only provision of the Safety Act that would apply after the first purchase of a vehicle is 15 U.S.C. S1397(a)(2)(A), which states in relevant part that:

No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle ... in compliance with an applicable Federal motor vehicle safety standard.

The first question to be answered is whether EG&G Idaho is a manufacturer. Under 49 CFR 568.3, a final-stage manufacturer is "a person who performs such manufacturing operations on an incomplete vehicle that it becomes a completed vehicle." An incomplete vehicle is "an assemblage consisting, as a minimum, of frame and chassis structure..." that requires "further manufacturing operations, other than the addition of readily attachable components... ." Readily attachable components include items such as mirrors or tire and rim assemblies. Service bodies are not "readily attachable components." Therefore, in installing service bodies on new chassis, EG&G is acting as a final-stage manufacturer under federal regulations.

49 CFR 586.6 establishes certain requirements for final-stage manufacturers,

including:

(a) Each final-stage manufacturer shall complete the vehicle in such a manner that it conforms to the standards in effect on the date of the manufacture of the incomplete vehicle, the date of final completion, or a date between those two dates. ... (b) Each final-stage manufacturer shall affix a label to the completed vehicle in accordance with S567.5 of this chapter.

EG&G must attach the proper label to the completed vehicle as set out in 49 CFR 567.5(c), a copy of which is enclosed for your convenience. According to your letter, EG&G mounts bodies in accordance with the original (i.e., incomplete) manufacturer's instructions or recommendations. In that case, EG&G's certification that the completed vehicle conforms to all applicable safety standards can state simply that the vehicle has been completed in accordance with the prior manufacturer's instructions, per S567.5(c)(7).

When EG&G mounts a new body on a new chassis, the resulting vehicle is subject to the Safety Act and the certification requirements of 49 CFR 567 and 568. However, according to your letter, you also mount bodies on "existing used" chassis. 49 CFR 571.7(e) deals with combining new and used components:

When a new cab is used in the assembly of a truck, the truck will be considered newly manufactured for purposes of paragraph (a) of this section (stating that safety standards apply to all relevant motor vehicles), the application of the requirements of this chapter, and the (Safety) Act, 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 means that the vehicle resulting from placing a new body upon a used chassis is a used vehicle. If, in addition to adding a new body, the operation also modifies the chassis by adding new components, such as new engine, transmission, suspension, etc., it is more likely that the resulting vehicle would be considered a new vehicle. If your vehicles produced with "existing used chassis" will incorporate the engine, transmission, and drive axle from the existing used chassis, the completed vehicles would be "used" and would not require vehicle certification. Some of our standards, however, apply to individual items of motor vehicle equipment (e.g., brake hoses and fluids, lighting equipment, tires, seatbelt assemblies, glazing). If your converted vehicles incorporate new items of these types of equipment, the items must comply with the applicable Federal safety standards. For example, lights are subject to requirements specified in Standard No. 108, and glazing is subject to requirements specified in Standard No. 205.

Finally, you ask whether "EG&G Idaho need(s) to be certificated... ." There is no procedure to certify any manufacturer. It is the manufacturer that must certify that its vehicles meet the applicable federal safety standards. However, you should submit the manufacturer's information required by 49 CFR 566 to NHTSA. This information includes the name and address of the manufacturer (in this case, EG&G), a description of the type of vehicle manufactured, the use for which it is intended, and the fact that EG&G is a final stage manufacturer. I have enclosed a copy of Part 566 for your

information.

For your information, I have also enclosed a general information sheet for new manufacturers that gives a succinct outline of the relevant NHTSA regulations and explains how to get copies of those regulations.

I hope this information is helpful. If you have any further questions or need some additional information on this subject, feel free to contact David Elias of my staff at this address or by telephone at (202) 366-2992.

TITLE: NONE

TEXT: This response to your letter asking this agency to consider a problem your company faces with respect to Standard 217, Bus Window Retention and Release (49 CFR @ 571.217). More specifically, you asked how some of your buses could be certified as complyi ng with the emergency exit labeling requirements set forth in Standard 217 for buses other than school buses. I apologize for the delay in this response.

Paragraph S5.5.1 of Standard 217 provides that, in buses other than school buses, each push-out window or other emergency exit shall have the designation "Emergency Exit" followed by concise operating instructions, describing each motion necessary to unl atch and open the exit, located within 6 inches of the release mechanism. The purpose of this requirement is to identify for bus occupants the location and explain the use of specially-installed emergency exits. As I understand your letter, you have no difficulties providing appropriate instructions in the specified location.

Paragraph S5.5.1 continues with the following language:

When a release mechanism is not located within an occupant space of an adjacent seat, a label . . . that indicates the location of the nearest release mechanism shall be placed within the occupant space.

The terms "adjacent seat" and "occupant space" are defined in S4 of Standard 217 as follows:

"Adjacent seat" means a designated seating position located so that some portion of its occupant space is not more than 10 inches from an emergency exit, for a distance of at least 15 inches measured horizontally and parallel to the exit.

"Occupant space" means the space directly above the seat and footwell, bounded vertically by the ceiling and horizontally by the

normally positioned seat back and the nearest obstruction of occupant motion in the direction the seat faces.

You stated that many of your buses have seats that face the aisle and that back up against windows designated as emergency exits. These aisle-facing seats are "adjacent seats" with respect to the emergency exits. The release mechanism for the emergency exit is not within the "occupant space" for these aisle-facing seats, since the release mechanisms are behind, not above, these seats. You enclosed a group of photographs to further illustrate this situation.

Since the release mechanism for the emergency exit is not within the occupant space of these adjacent aisle-facing seats, paragraph S5.5.1 of Standard 217 requires a label indicating the location of the release mechanism for the emergency exit to be plac ed within the occupant space for these seats. You have noted that the occupant space for these seats does not include any place to which this label could be attached. The nearest obstruction of occupant motion in the direction the aisle-facing seats fa ce is the aisle facing seat on the opposite side of the bus. There are no intervening objects other than narrow vertical stanchions in the center of the aisle. Additionally, you suggested that placing the label on the floor or ceiling of the bus would not serve the purposes of this requirement, since those locations would not be readily visible to the seated occupant in an emergency situation.

In response to your letter, we have carefully considered the labeling requirements of S5.5.1 as they apply to aisle-facing seats in front of windows that serve as emergency exits. The final rule adopting this additional labeling requirement explained th at NHTSA was concerned that an occupant of an adjacent seat might hinder egress through an emergency exit if the occupant did not know how to use the emergency exit. See 37 FR 9394, at 9395; May 10, 1972. In instances in which the release mechanism its elf is not within the occupant space of an adjacent seat, a label within the occupant space directing the occupant of the seat to the emergency exit instructions will help reduce the likelihood that the occupants would inadvertently obstruct egress throu gh the emergency exits.

NHTSA's goal of minimizing the likelihood of inadvertent obstruction of emergency exits is equally applicable to forward-facing and aisle-facing seats. However, the means of achieving that goal (i.e., placing a label within the occupant space of an adjac ent seat, if the release mechanism is not within that occupant space) may not be equally successful for forward-facing and aisle-facing seats. The agency did not focus upon aisle-facing seats when it adopted this labeling requirement. With respect to f orward-facing seats, it is relatively simple to locate a label within the occupant space that will be readily visible both to seated occupants and to persons standing in the aisle, as required by S5.5.2. However, with respect to aisle-facing seats, ther e may not be any location within the occupant space of such seats where a label could be placed so that the label would be visible to occupants of the seat and to persons standing in the aisle. If the labels were not visible in an emergency, such labels would not further NHTSA's goal of minimizing inadvertent obstruction of emergency exits.

Accordingly, we plan to issue a notice proposing to amend and clarify the requirements of S5.5.1 of Standard 217 as they apply to aisle-facing seats. Please note that, unless and until a final rule amending S5.5.1 of Standard 217 becomes effective, the c urrent requirements of S5.5.1 remain in effect for aisle-facing seats. However, the agency believes that it would be inappropriate at this time to enforce the requirement in S5.5.1 that additional information be labeled within the occupant space of aisl e-facing seats given the uncertainty that such labels will serve the purpose for which the labeling requirements were established, as noted above. Accordingly, until the agency makes a final decision on the proposed rulemaking mentioned above, NHTSA wil l not take any enforcement actions against bus manufacturers that do not place a label indicating the location of the nearest emergency exit release mechanism within the occupant space of adjacent aisle-facing seats.

Mr. Paul Collett
Liberty Motor Company Inc.
2390 South Service Road West
Oakville, Ontario
Canada, L6L 5M9




Dear Mr. Collett:

This responds to your letter and phone inquiry in which you asked several questions concerning the applicability of Federal Motor Vehicle Safety Standard (FMVSS) No. 206, Door locks and door retention components, to the modification of a vehicle to accommodate a wheelchair ramp. You first asked if a door latch assembly you described would comply with FMVSS No. 206. You then asked a series of questions based on a comparison of the door system you described and other door assembly designs. I have addressed your questions below.

In a conversation with Mr. Chris Calamita of my staff you stated that your company, Liberty Motor Company Inc. (Liberty), installs wheelchair ramps onto the back doors of minivans. Prior to installation of a ramp, you stated that the minivans typically have a "rear tailgate door with hinges at the top" and a single latch system located at the center of the bottom edge of the door. You explained that the installation requires lowering of the vehicle floor and the attachment of a folding ramp. As described in your letter, when the ramp is stowed it acts to "seal the door opening between the bottom of the closed tailgate door and the lowered floor".You further explained that the latch and striker of the original vehicle is removed and reinstalled onto the ramp so that when the back door is closed it latches to the stowed ramp.

You raised a variety of issues related to this type of modification. We have read your letter as requesting a response on two main issues: (1) is such a modification compliant with FMVSS No. 206, and (2) would such a modification result in a door system analogous to a cargo-door or "double side door" for purposes of the standard?

By way of background, the National Highway Traffic Safety Administration does not approve or certify any motor vehicle or modification of a motor vehicle. Instead, 49 U.S.C. 30115 establishes a "self- certification" process under which each manufacturer is responsible for certifying that its products meet all applicable FMVSSs. Generally, FMVSSs apply to motor vehicles up to their first sale for purposes other than resale (first retail sale). See 49 CFR 30112. After the first retail sale of a vehicle, manufacturers, distributors, dealers, and repair businesses are prohibited from "making inoperative" any device or element of design installed on or in a motor vehicle in compliance with an applicable standard (49 U.S.C. 30122; "make inoperative" provision).

1. Compliance with FMVSS No. 206

In equipping a vehicle with a wheelchair ramp your company would have to ensure that the modification did not take the vehicle out of compliance with all applicable FMVSSs, including FMVSS No. 206. S4.4 of FMVSS No. 206 specifies the requirements for hinged back doors. Each hinged back door system must be equipped with at least one primary latch and striker assembly as defined by the standard. The primary latch and striker assembly must not separate when subjected to the specified forces applied in the specified directions.

Another important standard to consider is FMVSS No. 214, Side impact protection. FMVSS No. 214 specifies safety requirements for vehicles subjected to impact by a moving deformable barrier at 33.5 mph. S5.3.2 of that standard specifies that any door (including a rear hatchback or tailgate), which is not struck by the barrier must not disengage from the latched position, must not have its latch separate from the striker, and must not have hinged components separate from each other or from their attachment to the vehicle. The latches and hinge systems of unstruck doors must not pull out of their anchorages.

The primary latch and striker provided by the original manufacturer must continue to meet these requirements as re-installed. However, nothing in our standards would expressly prohibit a design such as you described.

We note that on December 15, 2004, NHTSA published a notice of proposed rulemaking to update requirements and test procedures specified in the standard (69 FR 75021). If adopted, the proposal would add requirements and test procedures for sliding doors, add secondary latch position requirements for doors other than hinged side doors and back doors, provide a new test procedure for assessing inertial forces, and extend the application of the standard to buses with a gross vehicle weight rating of less than 10,000 pounds.

2. Similar Door Systems

You asked a series of questions based on the premise that the back door as modified would be analogous to a cargo-type door or a "[double] side door as found on some extended cab pick-up trucks. " We do not agree that the rear door / ramp system you described would be analogous to either of these door systems for the purposes of FMVSS No. 206.

FMVSS No. 206 defines a cargo-type door as:

[A] door designed primarily to accommodate cargo loading including, but not limited to, a two-part door that latches to itself.

Cargo-type doors are subject to more abbreviated standards than hinged back doors.

Contrary to the definition of "cargo-type doors", your door system is designed primarily to permit wheelchair occupants to enter and exit a vehicle. Further, in extending FMVSS No. 206 to hinged back doors, we rejected the idea of treating hinged back doors as cargo-type doors (60 FR 50124; September 28, 1995). The intent of S4.4 is to prevent the back door ejection of occupants by ensuring the integrity of latch/striker and hinge systems of back doors to reduce the incidence of unintended back door opening (60 FR at 50128).

The "double side door" systems described in your letter are located on the side of a vehicle and are therefore subject to the requirements applicable to hinged side doors. The door / ramp system described in your letter is located at the back of a vehicle and is therefore subject to the hinged back door requirements.

FMVSS No. 206 defines "back door" in part as:

[A] door or door system on the back end of a motor vehicle through which passengers can enter or depart the vehicle, or cargo can be loaded or unloaded[.] (Emphasis added. )

The portion of the ramp that acts to secure the back opening would be considered part of the back door system. Therefore, the system described in your letter would be a "hinged back door" for the purpose of FMVSS No. 206.

I hope you find this information helpful. If you have any additional questions please contact Mr. Chris Calamita of my staff at (202) 366-2992.

Sincerely,

Jacqueline Glassman
