Dear Mr. Takechi: This responds to your letter requesting an interpretation of Standar No. 101, *Controls and Displays.* Your questions are responded to below.; By way of background information, the National Highway Traffic Safet Administration does not provide approvals of motor vehicles or motor vehicle equipment. Under the National Traffic and Motor Vehicle Safety Act, it is the responsibility of the manufacturer to ensure that its motor vehicles or equipment comply with applicable safety standards. The following represents our opinion based on the facts provided in your letter.; Your first question concerns the identification requirements for master lighting switch. You stated your belief that if the headlamps and tail lamps are controlled by the master lighting switch, the switch is not required to be marked with any symbol other than that specified in Standard No. 101 for the master lighting switch. You also stated your belief that the manufacturer has an option to use other symbols in addition to that symbol. As discussed below, your understanding is correct.; Section S5.2.1(a) states: >>>Except as specified in S5.2.1(b), any hand- operated control liste in column 1 of Table 1 that has a symbol designated for it in column 3 of that table shall be identified by either the symbol designated column 3 (or symbol substantially similar in form to that shown in column 3) or the word or abbreviation shown in column 2 of that table.... Words or symbols in addition to the required symbol, word or abbreviation may be used at the manufacturer's discretion for the purpose of clarity....<<<; Column 3 of Table 1 designates the symbol shown in your letter for th master light switch. Also, footnote 2 of the Table states that separate identification is not required for headlamps and tail lamps if they are controlled by a master lighting switch. Thus, the master lighting switch symbol is sufficient identification under Standard No. 101 for the control identified in your letter.; A drawing provided with your letter shows various positions of th master lighting switch identified by a word or symbols, which are provided in addition to the master lighting switch symbol. As indicated in the above-quoted text, section S5.2.1(a) permits words or symbols in addition to the required symbol or word, for purposes of clarity.; Your second question concerns identification requirements for an uppe beam control. You stated that you believe no symbol is required for the upper beam control if it is on the turn signal lever, and that it is at the manufacturer's option to use a symbol.; Standard No. 101 does not specify any identification requirements fo an upper beam control, regardless of whether it is on the turn signal lever. Thus, the manufacturer has the option of deciding whether to identify the control and, if so, how to identify it. We note that the symbol you plan to use for future models is the same as designated in Standard No. 101 for the highbeam (upper beam) telltale. Thus, your planned approach appears desirable in minimizing the number of symbol's drivers must familiarize themselves with for the same function.; Sincerely, Erika Z. Jones, Chief Counsel

Dear Mr. Ullenberg: This is in reply to your letter of March 6, 1973, in which you as several questions regarding the certification of trucks with concrete mixers. You state that you supply a chassis to the Rex Chainbelt factory in Milwaukee, where a concrete mixer is installed. The combined unit is then shipped to a Rex dealer in Puerto Rico who sells the complete unit to a user. You provide weight ratings for the vehicle as follows: a gross vehicle weight rating, based on axle capacity, of 68,000 pounds, a rating, based on the tire capacity, of 56,740 pounds, and a gross weight of 66,800 pounds. Based on these figures you ask (1) Whether the truck can be completed in this fashion and shipped by you to Puerto Rico, (2) Whether the dealer in Puerto Rico can promise to install larger tires at a later date, (3) Whether Rex Chainbelt can certify the chassis at 68,000 pounds gross weight rating, if the dealer in Puerto Rico notifies Rex that he will change the tires at a later date, (4) Whether the chassis manufacturer can certify the truck chassis for a greater capacity than the lightest component if the local dealer or customer will notify him that they will bring the chassis to the higher certified level, and (5) What penalties can be imposed if a dealer or user does not make changes he has promised to make.; It appears to us from your letter that essentially the same issu underlies all your questions, that is, whether a final- stage manufacturer in completing a vehicle may place on it tires that are not sufficient to carry the vehicle at its gross vehicle weight rating, and elicit a promise from either a dealer or user that the latter will change the tires.; A truck that is equipped at the time of its manufacture with tire inadequate in terms of load rating to carry the truck at its gross vehicle weight rating would be considered by NHTSA to contain a safety related defect. The manufacturer of such a vehicle is subject to the provisions of section 113 of the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1402), which requires that notification of the defect be sent to first purchasers and dealers. A truck which was labeled with a gross vehicle weight rating below the minimum specified in 49 CFR 567(g)(3) would be in violation of the Certification regulations, and the person affixing such a label would be subject to civil penalties and other sanctions pursuant to section 108, 109, and 110 of the Safety Act (15 U.S. C. 1397, 1398, 1399). The Certification regulations (49 CFR Parts 567, 568) require weight ratings, in cases of vehicles manufactured in two or more stages, to be based on the vehicle as completed by the final-stage manufacturer. That manufacturer is not permitted to delegate his responsibility to a dealer or user.; The NHTSA has made an exception in the case of vehicles shipped withou tires, or vehicles shipped with temporary tires that are not intended to be used on the vehicle apart from the limited purpose of shipment. Your letter contains no implication that your case in within this exception.; Yours truly, Richard B. Dyson, Assistant Chief Counsel

Dear Senator Hartke: Thank you for your letter of March 7, 1975, asking for detaile consideration of Mr. David L. Daugherty's concern that final-stage manufacturers will be unable to fulfill their certification responsibilities on air-braked trucks built after March 1, 1975. As you know, Standard No. 121, *Air brake systems*, became effective for trucks and buses on March 1, 1975.; Mr. Daugherty has raised one of the most critical aspects of truc manufacturing in assuring a minimum brake performance level. Unlike passenger cars, the vast majority of heavy trucks are manufactured by adding specialized bodies or equipment to a chassis-cab. These additions affect the center of gravity, dynamic load transferral, and other characteristics of the truck which determine in large part its stopping capability.; As a practical matter, meaningful dynamic brake performance standard cannot be developed without regulating the truck as it is completed and sold.; The National Highway Traffic Safety Administration (NHTSA) recognize that Standard No. 121, as the first comprehensive performance requirement for trucks, will limit somewhat the freedom of manufacturers to modify brake systems and mount bodies without regard for their effect on braking. We consider the increased care exercised by final-stage manufacturers to be one of the most significant benefits of the standard.; Mr. Daugherty correctly points out that chassis-cab manufacturer released the necessary information on their chassis only a short time before March 1, 1975. The two trade associations for final-stage manufacturers petitioned for delay of the standard for this reason. After careful consideration of possible relief, NHTSA denied those petitions. It was concluded that every form of relief had obvious drawbacks and would not achieve the objective of final-stage manufacturers to receive 121-type chassis to use in re-engineering their body and equipment installations. It was concluded that if the standard for completed vehicles were suspended, chassis manufacturers would no longer have to provide incomplete vehicles with the necessary equipment and final-stage manufacturers would be unable to develop solutions for their engineering problems. Even if incomplete vehicles could be certified and completed vehicles could be exempt, serious danger would exist when modifications of the new systems were undertaken without consideration of the handling consequences.; I would like to point out that the March 1, 1975, effective date doe not require an instantaneous ('one day') change for final-stage manufacturers. Part 568 of our regulations (49 CFR Part 568) permits a final-stage manufacturer to use the date of completion of the chassis as the date of certification of the completed vehicle. This means that the chassis manufactured prior to March 1 may be completed at any later period without meeting Standard No. 121. It is not until final-stage manufacturers begin to receive the chassis which have just started to be produced that they will have to complete vehicles in conformity with the standard. They now have data on the new chassis, and thus have a period in which to make modifications. Several manufacturers have large inventories of pre-121 chassis and it should be several months before all trucks will be completed in conformity with Standard No. 121.; Thank you for your continuing interest in motor vehicle safety. Sincerely, James B. Gregory, Administrator

Dear Mr. McConnell: Thank you for your letter of July 31, 1986, inquiring about the Federa safety standards that apply to roll-up window shades designed to be attached to a vehicle's window by suction cups. The following discussion explains how our safety standards apply to your products.; Some background information on how Federal motor vehicle safety law and regulations affect your product may be helpful. Our agency 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. NHTSA, however, does not approve motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. Instead the Vehicle Safety Act establishes a 'self-certification' process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. The agency periodically tests vehicles and equipment items for compliance with the standards, and also investigates other alleged safety-related defects. As explained below, installation of products in new and used vehicles would be affected by our regulations. In addition, any manufacturer of motor vehicle equipment is subject to the requirements of the Vehicle Safety Act concerning the recall and remedy of products with noncompliances or defects related to motor vehicle safety.; We have issued Federal Motor Vehicle Safety Standard No. 205, *Glazin Materials*, which specifies performance and location requirements for glazing used in vehicles. These requirements include specifications for minimum levels of light transmittance (70% in areas requisite for driving visibility, which includes all windows in passenger cars).; No manufacturer or dealer is permitted to install solar films and othe sun screen devices, such as the ones described in your letter, in *new* vehicles without certifying that the vehicle continues to be in compliance with the light transmittance and other requirements of the standard.; After a vehicle is first sold to a consumer, modifications to a vehicl are affected by section 108(a)(2)(A) of the Vehicle Safety Act. That section prohibits commercial businesses from tampering with safety equipment installed on a vehicle in compliance with our standards. Thus, no dealer, manufacturer, repair business or distributor can install a sun screen device for the owner of the vehicle, if the device would cause the window not to meet the requirements of Standard No. 205. Violation of the 'render inoperative' provision can result in Federal civil penalties of up to $1,000 for each violation.; Section 108(a)(2)(A) does not affect vehicle owners, who may themselve alter their vehicles as they please, so long as they adhere to all State requirements. Under Federal law, the owner may install sun screening devices regardless of whether the installation adversely affects the light transmittance. Individual States govern the operational use of vehicles by their owners and therefore it is within the authority of the States to preclude owners from using sun screens in their vehicles.; I am returning, under separate cover, the two samples you provided th agency. If you need further information, please let me know.; Sincerely, Erika Z. Jones, Chief Counsel

"Dear Mr. Glover: This responds to your letter and telephone call about the child seat registration form you are considering. The form is required by S5.8 of Standard 213, 'Child Restraint Systems,' and is depicted in figures 9a and 9b of the standard. You ask whether S5.8(c) permits you to place certain additional information in the shaded area on the form. The information is a bar code that you said on the telephone contains information on 'date of manufacture, shift, location and serial number for the product that the card represents.' You explain that the bar code is desired because it can be automatically scanned, which would avoid possible 'mis-keying' of the information into the data record. Further, you state that the bar code has to be surrounded by a slightly larger unshaded 'quiet zone' to enable the scanner to record the bar code information. You are concerned whether NHTSA would conclude that the quiet zone renders a part of the shaded area unshaded. It is our opinion that a bar code that contains the information you described is permitted in the shaded area (the area outside of the space for the consumer to fill in). S5.8(c) of Standard 213 specifies the information that must be provided on the form and states the following: No other information shall appear on the postcard, except identifying information that distinguishes a particular child restraint system from other systems of that model name or number may be preprinted in the shaded area of the postcard, as shown in figure 9a. The bar code, printed in the shaded area, is permitted by S5.8(c). The information provided by the bar code distinguishes a particular child seat from another of the same model name or number. We consider the quiet zone as part of the bar code since it is needed for the bar code to be reliably read. The quiet zone therefore need not be shaded, since the printed bar code (or any other identifying information permitted by S5.8(c)) itself is not. Please note that, while the bar code is permitted, the information on the model name or number and date of manufacture must still be in English under S5.8(c). This information must be in English so that a consumer can see that this information has been provided and that only minimal effort is needed to fill out the registration form. We also wish to note another feature of the form you faxed. Your form has the words 'please print' after the instructions to the consumer 'just fill in your name and address.' 'Please print' is not on the form depicted in figures 9a and 9b of Standard 213. In an earlier letter, NHTSA decided that a minor variation in the wording of a warning expressly specified by Standard 213 was permitted when the change clarified the warning and did not make any substantive change to the warning's meaning. (Letter to Mr. McGuigan, December 18, 1980.) Similarly, 'please print' is a minor variation to the wording of the instructions that clarifies the instructions and does not substantively change them. Thus, it is permitted. I hope this information is helpful. Please call Ms. Fujita at (202) 366-2992 if you have further questions. Sincerely, John Womack Acting Chief Counsel";

Dear Ms. Phillips: This responds to your letter of November 16, 1981, concernin differences between the Vehicle Equipment Safety Commission (VESC) Regulation on sun screening devices and applicable Federal standards. In addition, you asked about the requirements of several Federal motor vehicle safety standards and how they affect Pennsylvania vehicle inspection standards.; Your first question concerns any differences in light transmittanc requirements between the Federal standard and the 70 percent light transmittance requirement set by VESC in its Regulation No. 20, *Performance Requirements for Motor Vehicle Sun Screening Devices*. We have issued a Federal Motor Vehicle Safety Standard No. 205, *Glazing Materials*, which specifies performance and location requirements for glazing used in vehicles. The standard sets a minimum light transmittance level of 70 percent for glazing materials used in areas requisite for driving visibility, such as the windshield and front side windows.; As explained in the enclosed letter, the agency does not consider su screening solar films to be glazing materials themselves and thus they would not have to comply with Standard No. 205. However, as the enclosed letter explains, use of such devices on motor vehicles would be prohibited in certain cases if the vehicle glazing no longer complies with the light transmittance or other requirements of the standard.; You also asked if bumper height is regulated by a Federal standard. Th agency has issued, under the authority of the Motor Vehicle Information and Cost Savings Act (15 U.S.C. 1901 *et seq*.) and the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1391 *et seq*.), a Part 581 Bumper Standard (49 CFR Part 581, copy enclosed) that specifies performance requirements for bumper systems. One aspect of performance regulated by the standard is the impact protection provided by the bumper at certain heights.; Section 110 of the Cost Savings Act (15 U.S.C. 1920) provides, i applicable part, that:; >>>No State or political subdivision thereof shall have any authorit to establish or enforce with respect to any passenger motor vehicle or passenger motor vehicle equipment offered for sale any bumper standard which is not identical to a Federal bumper standard.<<<; Section 103(d) of the Vehicle Safety Act (15 U.S.C. 1392(d)) provides in applicable part, that:; >>>Whenever a Federal motor vehicle safety standard established unde this title is in effect, no State or political subdivision of a State shall have any authority either to establish, or to continue in effect, with respect to any motor vehicle or item of motor vehicle equipment any safety standard applicable to the same aspect of performance of such vehicle or item of equipment which is not identical to the Federal standard.<<<; Therefore, unless the Pennsylvania regulation is identical to the Par 581 Bumper Standard, it is preempted.; Finally, you asked about Federal safety standards regulating the heigh of the windshield. The agency has not issued any safety standard specifying requirements for the vertical height of the windshield. Therefore, Pennsylvania's inspection standard on vertical windshield height is not preempted.; Sincerely, Frank Berndt, Chief Counsel

Dear Mr. Keller:

This responds to your recent correspondence where you ask whether defeating a seat cushion occupant classification system on a vehicle manufactured before September 1, 2006, would constitute making the system inoperative when the vehicle modification is performed to accommodate the needs of a person with a disability. I am pleased to be able to provide a response.

By way of background, the National Highway Traffic Safety Administration (NHTSA) administers a statute requiring that motor vehicles manufactured for sale in the United States or imported into the United States be manufactured so as to reduce the likelihood of motor vehicle crashes and of deaths and injuries when crashes do occur. That statute is the National Traffic and Motor Vehicle Safety Act of 1966 ("Vehicle Safety Act") (recodified at 49 U.S.C. 30101, et seq.).

One of the agency's functions under that Act is to issue and enforce the Federal motor vehicle safety standards (FMVSSs). These standards specify safety performance requirements for motor vehicles and/or items of motor vehicle equipment. Manufacturers of motor vehicles must certify compliance with all applicable safety standards and permanently apply a label to each vehicle stating that the vehicle complies with all applicable FMVSSs and providing the vehicle gross vehicle weight rating (GVWR). Alterers of motor vehicles are companies that modify a completed vehicle prior to first retail sale. Alterers must determine whether those modifications could affect the vehicle manufacturer's certification of compliance and, if so, must certify that the vehicle continues to comply with those safety standards that were affected by the modification.

The Vehicle Safety Act also prohibits manufacturers, distributors, dealers, 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 motor vehicle equipment that is in compliance with any applicable FMVSS (49 U.S.C. 30122). If NHTSA determines that a business has violated the make inoperative provision, it may assess a civil penalty in the amount of $5,000 per violation (not to exceed $15,000,000 in the aggregate). NHTSA may, through regulation, exempt a person or business from the prohibition if it decides that an exemption is consistent with motor vehicle safety and the Vehicle Safety Act.

On February 27, 2001, NHTSA published a final rule setting forth a limited exemption from the make inoperative prohibition for businesses or individuals who modify vehicles for persons with disabilities (66 Federal Register 12638; Docket No. NHTSA-01-8667). This exemption is codified in 49 CFR Part 595. Only portions of some FMVSSs are covered by the exemption. Additionally, the exemption only applies to modifications made after the first retail sale of the vehicle.

On May 8, 2000, NHTSA published a final rule amending FMVSS No. 208, Occupant crash protection, to add several new requirements to minimize the risk of air bags to children and small adults, while maintaining the benefits of the air bags for all other front seat occupants. These requirements are collectively referred to as the "advanced air bag" requirements of FMVSS No. 208. They apply to all vehicles manufactured for sale or use in the United States with a GVWR of 8,500 pounds or less and an unloaded vehicle weight of 5,500 pounds or less (other than walk-in van-type trucks or vehicles manufactured exclusively for the U.S. Postal service).

The advanced air bag requirements are subject to a phase-in, whereby, generally speaking, ⁽¹⁾ at least 35% of a given vehicle manufacturer's fleet must comply with the requirements between September 1, 2003, and August 31, 2004, 65% of its fleet must comply between September 1, 2004, and August 31, 2005, and 100% of its fleet must comply between September 1, 2005, and August 31, 2006. Vehicles manufactured in two or more stages or by companies manufacturing less than 5,000 vehicles for the U.S. market per year must meet the advanced air bag requirements in all vehicles produced on or after September 1, 2006.

In amending FMVSS No. 208, NHTSA contemplated three different types of technologies that could be used, individually or in combination, to minimize air bag risks to children seated in the front seat of a vehicle. First, the rule allows vehicle manufacturers to certify compliance with the new requirements by using a system that suppresses the air bag when a small child is sitting in the front seat (automatic suppression system requirements). Second, manufacturers may deploy the air bag for a small child using a system that is unlikely to injure the child when the air bag deploys (low-risk deployment system requirements). Finally, manufacturers may use a system that suppresses the air bag whenever any occupant moves far enough into the air bag's deployment zone that an air bag related injury could result (dynamic automatic suppression system requirements).

Some of the technologies contemplated by manufacturers to meet these requirements are located in the passenger seat. When such systems are used, removal of the seat would make the suppression system inoperative.

Subpart C of Part 595 does not include the advanced air bag requirements of FMVSS No. 208 among the provisions for which an exemption may be granted. We are reviewing a petition for rulemaking that requests us to amend Part 595 to allow modifiers to make these systems inoperative. We anticipate that if we decide to so amend Part 595, the amendment will become effective before September 1, 2003, the beginning of the phase-in.

Until we amend Part 595 to include the advanced air bag requirements, a vehicle modifier must retain the vehicle features relied upon by the manufacturer for compliance with those requirements. A vehicle manufacturer is permitted to certify compliance with the advanced air bag requirements of FMVSS No. 208 before the beginning of the phase-in. If a vehicle manufacturer relies on a seat-based occupant detection system to certify a vehicle's compliance, regardless of whether it manufactures the vehicle before the beginning of the phase-in, removing a seat containing the system would make the vehicle's compliance "inoperative" within the meaning of 49 U.S.C. 30122.

In such a case, a modifier may not remove the system unless NHTSA has issued a letter stating that it will not enforce the make inoperative prohibition for the work performed on the vehicle. Accordingly, a vehicle modifier should assure itself that the vehicle manufacturer is not relying on a seat-based occupant detection system to comply with the advanced air bag requirements before removing the passenger seat. If the seat-based system is relied upon for compliance, the modifier may request written agency approval of to the required modification. Any requests for such a letter should be submitted to this office.

I hope this addresses your concerns on this issue. Should you require any additional information or assistance, please contact Rebecca MacPherson, of my staff, at (202) 366-2992 or at the address given above.

Sincerely,

Jacqueline Glassman
Chief Counsel

d.5/2/02

---

¹ Manufacturers who produce two or fewer car lines for the U.S. market may opt out of the phase-in schedule if 100% of their vehicles meet the advanced air bag requirements beginning September 1, 2004. Final-stage manufacturers and very small vehicle manufacturers (no more than 5,000 vehicles per year) are not required to comply with these new requirements during the phase-in period.

Mr. Yueh-An Chen Division Head Planning Division Yue Loong Motor Engineering Center P.O. Box 510 Taoyuan, Taiwan Republic of China

Dear Mr. Chen:

This is in reply to your letter of June 5, 1987, asking whether certain rear lighting arrangements are acceptable under Federal Motor Vehicle Safety Standard No. 108.

You have submitted a diagram showing four lamps on either side of the vertical centerline of the rear of the car. The most inboard lamps, denoted "R", are the backup lamp system. Yue Loong contemplates four different functions for the remaining three sys tems of lamps, "A", "B", "C", and "D", "E", "F" (inboard to outboard) and asks about acceptability.

1. In the first system, ABC or DEF will serve the respective turn signal functions. All lamps would serve as hazard warning signal lamps and stop lamps. Standard No. 108 generally does not prohibit lamp clusters from performing multiple functions. This s ystem is permissible as long as ABC and DEF meet all Standard No. 108's requirements for turn, hazard warning, and stop signals when tested in those modes. Your diagram, however, does not indicate which, if any, of these lamps provide the taillamp functi on that Standard No. 108 also requires for the rear of motor vehicles. Therefore, lamps ABC and DEF would have to meet the taillamp requirements as well.

2. The second system differs from the first in that the hazard warning system would not operate through all six lamps of the turn signal system, but only through the two most outboard lamps. This system is permissible, as Standard No. 108 does nor mandat e use of all turn signal lamps for the hazard warning signal mode, requiring only "at least one" on each side of the vehicle, front and rear.

3. The third system differs from the second in that the two most outboard lamps would no longer be part of the stop lamp system. We view this arrangement as permissible. Standard No. 108 requires that stop lamps, turn signal lamps, and taillamps be locat ed "as far apart as practicable". In a literal sense this would appear to require stacking the lamps vertically at the outboard edges of the vehicle, but NHTSA has not adopted a design-restrictive interpretation of this requirement. The determination of practicability is initially that of the manufacturer, but it is subject to review and comment by this agency in instances where such a determination appears clearly erroneous. Where the turn signal system (or part of it) is located at the outboard edges of the vehicle, and the stop lamps and taillamps are adjacent to it, or to each other, we view the "practicability" requirement as met.

4. The fourth system differs from the third in that the stop lamp system would be either that of the systems discussed in items 2 and 3 above, and operating according to Section 3 of your letter. Either system would be acceptable, subject to the operatio nal restriction with turn signal lamps that I shall discuss in my response to Section 3.

Next, you have presented four kinds of flashing arrangements for the turn signal lamps. You ask (a) which could meet Standard No. 108, and (b) which could meet Standard No. 108 assuming a flash cycle of 1-4 seconds. With respect to (a), all four would ap pear to be acceptable. The standard allows multiple turn signal lamps either to flash simultaneously, or sequentially in the direction of the turn. With respect to (b), Standard No. 108 specifies that a turn signal flasher provide not less than 60 and no t more than 120 cycles per minute. This translates to not less than 1 and not more than 2 cycles per second. This requirement would have to be met by all lamps in arrangement i.e. where all lamps operate simultaneously. When operating sequentially, each lamp individually would be subject to the restrictions with the result that the inclusive cycle for a three lamp system would be not less than 3 seconds and not more than 6 seconds. Therefore, arrangements (a), (b), and (c) would meet this requirement as suming a flash cycle of 4 seconds, but arrangement (d) would not, being restricted to a cycle of 2 seconds maximum.

In your third question, or Section 3 as you term it, you have combined the conditions of your first two questions and attached a table of "detailed operating states" of the rear lamps, which incorporates three attached figures, with the question whether it would comply with Standard No. 108. Two of the Operating States illustrated denote the stop lamp "on" and, individually, the right or left turn signal as "on". Standard No. 108 does not allow simultaneous activation of the stop lamp and turn signal la mp when the stop signal is optically combined with the turn signal, In that event, the circuit must be such that the stop signal cannot be turned on in the turn signal which is flashing (paragraph 4.2, SAE Standard J586c Stop Lamps, August 1970, incorpor ated by reference in Standard No. 108). Our other comment concerns "Fig. a", "Fig. b", and "Fig. c" depicting flash cycles of the turn signal lamp;. As we noted earlier, the individual lamps are subject to the cycle minima and maxima of 1 to 2 cycles per second, and none of the rates depicted in the three Figures appears to meet the minimum requirement of 1 second. Otherwise, the "Operating State" table appears acceptable.

I hope that this answers your questions.

Sincerely,

Erika Z. Jones Chief Counsel

Dear Mr. Jones,

On Jan. 23, 1986 we consulted NHTSA about the problems of headlamps systems, and received your reply letter of May. 8, 1986. The information was very useful to us, thank you again for your kind assistance.

Now, we still have some questions about the turn signal lamps and other rear lamps, will you please kindly give us your suggestions as soon as possible?

The feature of rear lamps of the vehicle is shown as fig. 1. In the following conditions, which could meet the requirements of the FMVSS No. 108 and other related U.S.A. regulations?

1. As shown in Fig. 1, "R", is the backup lamp, and the lighting function of the other lamps "A", "B", "C", "D", "E", "F" are shown as Table 1. In the four cases, which could meet the requirements of U.S.A. regulations?

2. As shown in Fig. 2, there are four kinds of flashing arrangements for the turn signal lamps "ABC" (LH) & "DEF" (RH). a. Which could meet the requirements of U.S.A. regulations? b. If the period of flashing (t) 1 cycle = 1 - 4 sec. which could meet the requirements of U.S.A. regulations?

3. Combining the conditions of section 1, 2, we set a detailed operating state of the rear lamps as shown in Table 2. Could it meet the requirements of U.S.A. regulations?

Your kind assistance and earlier reply will be highly appreciated.

ATTACHMT: Attached to letter dated 12/21/93 from Carl Haywood to John Womack

TEXT:

This responds to your letter of December 21, 1993, requesting information about seating requirements for emergency response units you are designing to respond to chemical spills. The response units are tractor trailer combinations which can be driven in and out of the cargo bay of C-130 Hercules aircraft which are used to transport the units to the site. You further describe the response units as follows:

Our response units are designed to transport all six (6) of our response team members, for over the highway transportation three (3) of our team members will ride in the tractor and the remaining three (3) will ride in the trailer. D uring air transportation all six (6) team members will ride in the trailer. By providing seating with lap and shoulder restraints in the response unit for both ground and air transportation we eliminate the need for special crew cabins for air transportation, and extra vehicles for ground transportation. This conserves the limited space available on the C-130 allowing us to carry all the equipment needed to respond effectively to large scale chemical releases.

You requested information on the regulation of the seating in the response units. You have already contacted several Department of Transportation agencies, including the Federal Aviation Administration.

I am pleased to have this opportunity to explain our regulations to you. Some background information on Federal motor vehicle safety laws and regulations may be helpful. Our agency is authorized, under the National Traffic and Motor Vehicle Safety Act (15 U.S.C. S1381 et seq., Safety Act), to issue safety standards applicable to new motor vehicles and items of motor vehicle equipment. The Safety Act defines the term "motor vehicle" as follows:

any 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.

If a vehicle is a "motor vehicle" under the definition, then the vehicle must comply with all applicable safety standards, including those related to seating and occupant restraint. However, if a vehicle is not a motor vehicle under this definition, the n the vehicle need not comply with the agency's safety standards because such a vehicle is outside the agency's scope of authority.

Applying this definition to the response units, NHTSA believes the response units are motor vehicles within the meaning of the Safety Act. In determining whether a vehicle which has both on-road and off-road uses is a motor vehicle, the agency looks at whether the vehicle uses public roads on a necessary and

recurring basis. Applying this criteria to the response units, we believe that the response units have a primary function of highway transportation of personnel and equipment to the chemical spill site.

NHTSA's safety standards specify different requirements for different types of motor vehicles. Therefore, in order to determine the occupant seating requirements for the response units, it is necessary to determine how these vehicles are classified unde r our regulations. NHTSA he fines a "truck" as "a motor vehicle with motive power, except a trailer, designed primarily for the transportation of property or special purpose equipment." The tractor portion of the response unit has seating capacity for at least three passengers, but its primary use appears to be to draw the trailer. Therefore, it appears that this vehicle is a "truck" for the purpose of Federal regulations.

NHTSA defines a "trailer" as "a motor vehicle with or without motive power, designed for carrying persons or property and for being drawn by another motor vehicle." NHTSA believes the trailer portion of the response units would be considered trailers fo r the purpose of Federal regulations.

NHTSA has exercised its authority under the Safety Act to issue four safety standards relevant to occupant seating and restraint: Standard No. 207, Seating Systems, Standard No. 208, Occupant Crash Protection, Standard No. 209, Seat Belt Assemblies, and Standard No. 210, Seat Belt Assembly Anchorages.

Standard No. 207 establishes strength and other performance requirements for all "occupant seats" in passenger cars, multipurpose passenger vehicles, and trucks, and for the driver's seats in buses, except that the requirements do not apply to side-facin g seats. Therefore, all "occupant seats" in tractor portion of the response units must meet the requirements of Standard No. 207. Standard No. 207 does not apply to trailers, therefore, the seats in the trailer portion of the response units are not subj ect to the requirements of Standard No. 207.

Standard No. 208 specifies occupant protection requirements based on vehicle type and seating position within the vehicle. Different requirements also apply depending on the GVWR of the vehicle. The discussion which follows is limited to vehicles with a GVWR greater than 10,000 pounds. As explained below, trucks are required to have, at a minimum, a lap belt at every designated seating position. As with Standard No. 207, Standard No. 208 does not apply to trailers. Therefore, the seats in the trail er portion of the response units are not required to have any type of safety belt at any seating position.

The requirements for trucks with a GVWR of 10,000 pounds or more are contained in section S4.3 of Standard No. 208. Vehicle manufacturers have a choice of two options for providing occupant crash protection in trucks manufactured on or after September 1 , 1990. Option 1 requires vehicle manufacturers to provide an automatic protection system at all seating positions that meets the frontal and lateral crash protection and rollover requirements. Option 2 requires vehicle manufacturers to install lap or lap/shoulder belts at every seating position. If a manufacturer chooses to comply with Option 2, the lap belt or pelvic portion of a lap/shoulder belt must have either an emergency locking retractor or an automatic locking retractor.

Standard No. 209 sets forth strength, elongation, webbing width, durability, and other requirements for seat belt assemblies. This standard applies to all seat belt assemblies as separate items of motor vehicle equipment, regardless of whether the belts are installed as original equipment in a motor vehicle or sold as replacements. Thus, if seat belts are voluntarily installed at the seats in the trailer portion of the response units, the seat belts would be required to comply with Standard No. 209.

Standard No. 210 establishes strength and location requirements for seat belt anchorages installed in vehicles, where seat belts are required by Standard No. 208. Therefore, anchorages are required for the lap belts in the tractor, but are not required in the trailer.

Although all of the safety standards cited in this letter do not apply to each seating position in your proposed emergency response unit, the agency nevertheless encourages additional consideration and application of those performance requirements that a re appropriate to a safe design.

TITLE: None

ATTACHMT: Attached to letter dated 11-10-92 from Duane Bartels to NHTSA (OCC 8022)

TEXT: This responds to your letter requesting information on how the agency's regulations would affect a Minnesota resident wishing to change the seating in passenger vans by removing or modifying seats in the vans. The contemplated changes would reduce the seating in a 12 or 15 passenger van to a maximum of 10 persons. I will give you some background information concerning the relevant rules, and then proceed to answer your four questions.

The National Traffic and Motor Vehicle Safety Act ("Safety Act") authorizes the National Highway Traffic Safety Administration ("NHTSA") to issue safety standards applicable to new motor vehicles and items of motor vehicle equipment. NHTSA does not approve motor vehicles or equipment, however. Instead, the Safety Act establishes a "self-certification" process under which each manufacturer of a new motor vehicle or items of equipment is responsible for certifying that its products meet all applicable safety standards.

If any party performs conversion operations (i.e., anything other than addition or removal of readily attachable components such as mirrors or tires, or minor finishing operations such as painting, see 49 CFR S567.6) on a certified vehicle before the first sale of the vehicle to a consumer, the party would be an "alterer" under 49 CFR S567.7, and would be required to affix its own label identifying itself and certifying that the altered vehicle continues to conform to all applicable Federal motor vehicle safety standards affected by the alteration.

If alterations are made to a vehicle after its first sale to a consumer, there are no certification requirements. However, under section 108(a)(2)(A) of the Safety Act, manufacturers, distributors, dealers, or motor vehicle repair businesses modifying a used vehicle are prohibited from knowingly rendering inoperative any safety device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard. The "render inoperative" provision does not apply to modifications vehicle owners make to their own vehicles.

Let me now proceed to answer each of your four questions:

1. BY DOING THIS ALTERING TO SEATS, IS HE DOING ENOUGH WORK TO THE VEHICLE TO QUALIFY UNDER 49 CFR 567.7?

If the modifications are carried out prior to a vehicle's first sale to a consumer, the person to whom you refer in your letter would be considered an alterer under 49 CFR S567.7. As discussed above, an alterer would be required to affix its own label identifying itself and certifying that the altered vehicle continues to conform to all applicable Federal motor vehicle safety standards affected by the alteration.

I note that, if alterations change the classification of a vehicle, the alterer must certify that the vehicle meets all Federal safety standards applicable to the new classification. As you noted in your letter, the contemplated alterations, resulting in a change in capacity from either 12 or 15 passengers to a maximum of 10 persons, would change the vehicle's classification from "bus" to "multipurpose passenger vehicle (MPV)," under 49 CFR Part 571.3. The alterer would therefore be required to certify that the altered vehicle meets all Federal safety standards applicable to MPV's. I note that different safety standards apply to MPV's and buses.

If the modifications are made to a used vehicle, the person to whom you refer in your letter would not be considered an alterer. However, if the person is a manufacturer, distributor, dealer or motor vehicle repair business, the person would have to take care not to violate to the "render inoperative" provision discussed above.

2. WILL THIS PERSON BECOME A MANUFACTURER AND IF SO, DOES HE NEED TO COMPLY WITH 49 CFR 566.5?

Alterers are considered manufacturers under the Safety Act. Since 49 CFR 566.5 sets forth requirements for "each manufacturer of motor vehicles," alterers must file the information required by that section. This information includes the name of the manufacturer, its address, and a brief description of the vehicle or vehicle equipment manufactured.

I note that NHTSA has issued several previous interpretation letters addressing the question of whether alterers must file under 49 CFR 566.5, and has taken positions which are difficult to reconcile. In at least one early letter (October 30, 1975 letter to Mr. James E. Harris), the agency indicated that some alterations might be so minor that the alterer might not be considered a manufacturer. In another letter (May 12, 1976, addressed to Mr. Mike Watson), the agency stated that a person who alters completed vehicles but "does not otherwise manufacture" vehicles or equipment is not required to file under section 566.5. In still other letters (see, e.g., April 4, 1973 letter to Mr. Warren Morris and July 5, 1985 letter to Houston N. Tuel, Jr., Esq.), NHTSA stated that alterations which change vehicle category are sufficient to require the person making the alterations to file under 566.5.

After reviewing 49 CFR 566.5 in light of these earlier letters, we have concluded that alterers (persons required to attach a label under 49 CFR Part 567.7) are subject to the filing requirements of section 566.5. First, there is nothing in Part 566 which indicates that alterers are excluded from the filing requirements. Second, application of the filing requirements to alterers is consistent with one of the stated purposes of Part 566, facilitating the regulation of manufacturers under the Safety Act. As indicated above, section 567.7 requires an alterer to affix a label identifying itself and certifying that the altered vehicle continues to conform to all applicable Federal motor vehicle safety standards affected by the alteration. If the agency believes that there may be a safety problem with work that has been performed by an alterer, the information submitted under Part 566 makes it easier to find and contact the alterer. I note that the burden on manufacturers (including alterers) complying with section 566.6 is minimal.

3. CAN HE PURCHASE A NEW VEHICLE, DO THE ALTERING AND RESELL THE VEHICLE OR

MUST AN OWNER BRING THE VEHICLE TO HIM AND HAVE THE ALTERING DONE?

Modifications can be carried out both on new vehicles (prior to first sale to a consumer) and on used vehicles. As discussed above, however, different requirements apply to these two situations.

4. CAN THIS ALTERING AND RECERTIFYING BE DONE ONLY TO A NEW VEHICLE OR CAN THIS BE DONE TO A USED VEHICLE?

As discussed above, while modifications can be carried out both on new vehicles and on used vehicles, the certification requirements only apply to persons making modifications to new vehicles. Thus, a "certification" of a used vehicle would not have any legal significance under the Safety Act.

I note that your letter states that one of the ways the person may modify seats is to do upholstery work to reduce the number of people that can sit in a seat.

However, modifications to seat upholstery will not result in reduced designated seating capacity unless the modified design is such that the extra area CANNOT be used for seating. I have enclosed two letters to Nissan, dated 8/15/79 and 10/1/79, which explain our position in greater detail.

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