TEXT: Dear Mr. Williams:

This responds to your letter requesting information about Federal requirements related to a product that "sets the brakes on an air brake vehicle when the driver exits the cab." I apologize for the delay in our response. You stated that your "device doe s not hook into the brake system but pops the parking button out if the driver is off the seat and the door is open. The brake then must be manually disengaged." You requested confirmation that the agency will neither support nor oppose the aftermarket installation of such a device.

I am pleased to have this opportunity to explain our regulations to you. I am also enclosing a copy of a fact sheet entitled "Information for New Manufacturers of Motor Vehicles and Motor Vehicle Equipment."

By way of background information, the National Highway Traffic Administration (NHTSA) 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 manufa cturer to ensure that its vehicles or equipment comply with all applicable standards. The following represents our opinion based on the facts provided in your letter.

NHTSA does not have any specific regulations about a product such as your device. However, since this device is related to a vehicle's air brake system, it could affect a vehicle's compliance with Standard No. 121, Air Brake Systems. That standard appli es to almost all new trucks, buses, and trailers equipped with air brake systems.

If your system is installed as original equipment on a new vehicle, the vehicle manufacturer is required to certify that, with the device installed, the vehicle satisfies the requirements of all applicable safety standards, including Standard No. 121. ( See 15 U.S.C. @ 1397(a)(1) and 49 CFR Part

2

567). If the device is added to a previously certified new motor vehicle prior to its first consumer purchase, then the person who modifies the vehicle would be an alterer of a previously certified motor vehicle and would be required to certify that, as altered, the vehicle continues to comply with all of the safety standards affected by the alteration. 49 CFR @ 567.7.

If the device is installed on a used vehicle by a manufacturer, distributor, dealer, or motor vehicle repair business, then the installer would not be required to attach a certification label. However, it would have to make sure that it did not knowingl y render inoperative, in whole or in part, any 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. 15 U.S.C. @ 1397(a)(2)(A). In parti cular, these entities should ensure that the installation of your device does not render inoperative the vehicle's compliance with the parking brake requirements set forth in S5.6.

I hope this information is helpful. If you have any questions about NHTSA's safety standards, please feel free to contact Marvin-Shaw at this address or by telephone at (202) 366-2992.

Sincerely,

TEXT: Dear Mr. Klingaman:

This responds to your March 16, 1994, letter inquiring about the applicability of National Highway Traffic Safety Administration (NHTSA) regulations to the alteration of used motor vehicles. You stated that your company manufactures water trucks and lub e/fuel service trucks by adding water tanks and various other apparatus to incomplete vehicles. Your question is whether you are required to add a certification label (as required in 49 C.F.R. @ 571.115) even if you use a "pre-owned" (I assume you mean "used") truck chassis.

Some background information on Federal motor vehicle safety laws and regulations may be helpful. As you are aware, our agency is authorized under the National Traffic and Motor Vehicle Safety Act (15 U.S.C. @ 1381 et seg.; Safety Act), to issue safety s tandards 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 Safety Act establishes a "self-cer tification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards.

Whether Inter Pipe, Inc. would have to apply a certification label depends upon whether the vehicles your company modifies are new (that is, the vehicles have not yet been sold to the first retail purchaser) or used (vehicles that have already been sold to and used by the first retail purchaser). With respect to your company's modifications of new vehicles, your company would be a "final stage manufacturer" for the purposes of NHTSA's laws and regulations. 49 C.F.R. @ 568.6 requires a final stage manu facturer of a new vehicle to affix a certification label in accordance with 49 C.F.R. @ 567.5.

The requirements of 49 C.F.R. Parts 567-568 do not apply if you modify used vehicles. Hence, your company is not

2

required to affix a manufacturer's label to those used vehicles you convert into water trucks or fuel/lube trucks. However, @ 108(a)(2)(A) of the Safety Act provides that no manufacturer, distributor, dealer, or motor vehicle repair business may knowing ly "render inoperative," in whole or in part, any 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. Therefore, you must be careful wh en adding your equipment not to degrade the truck's ability to meet the safety standards.

For your information, I have enclosed a general information sheet for manufacturers that gives a thumbnail sketch 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 our office at (202) 366-2992.

This responds to your request of April 13, 1994, for an interpretation of Motor Vehicle Safety Standard No. 108.

You reference paragraphs S5.5.7(a) and (b) which apply to vehicles of less than 80 inches overall width and ask whether there are similar requirements for wider vehicles.

Paragraph S5.5.7(a) requires that "(w)hen the parking lamps are activated, the tail lamps, license plate lamps, and side marker lamps shall also be activated." There is no similar requirement for vehicles whose overall width is 80 inches or more because these vehicles are not required to have parking lamps (see Table I of Standard No. 108).

Paragraph S5.5.7(b) requires that "(w)hen the headlamps are activated in a steady-burning state, the tail lamps, parking lamps, license plate lamps and side marker lamps shall also be activated." Paragraph S5.5.3 requires tail lamps on all vehicles, reg ardless of width, to be activated when the headlamps are activated in a steady burning state. As noted in the preceding paragraph, wide vehicles are not required to have parking lamps.

This leaves the question of license plate lamps and side marker lamps. As you have surmised, there is no specific requirement in Standard No. 108 that these lamps be simultaneously activated with the headlamps on vehicles whose overall width is 80 inche s or greater. However, we understand that it is industry practice to wire its large vehicles in this manner. We also believe that those who do not wire the side marker lamps to operate with the headlamps include them in the separate switch that activat es the clearance and identification lamps.

TEXT:

This responds to your letter about the brake reservoir requirements of Federal Motor Vehicle Safety Standard No. 121, Air Brake Systems (49 CFR S571.121). I apologize for the delay in our response. You stated that you are developing a new reservoir des ign to improve reservoir volume without increasing the need for space. You asked how to test your reservoirs since you believe that "(t)he safety standard does not clarify the test criteria specifically how the reservoir is to be sealed."

By way of background information, the National Highway Traffic Safety 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 manufa cturer to ensure that its vehicles and equipment meet applicable requirements. The following represents our opinion based on the facts provided in your letter.

Standard No. 121 establishes performance and equipment requirements for braking systems on vehicles equipped with air brakes. The Standard's reservoir requirements for trucks and buses are set forth in section S5.1.2. That section requires these vehicle s to be equipped with one or more service reservoir systems that meet specified performance requirements. Section S5.1.2.2 specifies the following:

Each reservoir shall be capable of withstanding an internal hydrostatic pressure of five times the compressor cutout pressure or 500 psi, whichever is greater, for 10 minutes.

The purpose of this requirement is to ensure that an air brake system reservoir has a minimum level of structural integrity. NHTSA has long interpreted the term "withstand" to require that there be no rupture or permanent circumferential deformation of the reservoir exceeding one percent. At one point, the agency issued an interpretation concluding that the term "withstand" meant that a reservoir can deform only slightly and must contain the applied pressure with only a limited pressure drop at any ti me during the test. However, NHTSA later withdrew that interpretation because it inadvertently increased the severity of the requirement. See 42 FR 64630, December 27, 1977, and 43 FR 9149, March 6, 1978.

You asked about this requirement in connection with a reservoir design that includes a bushing on the inside of an endcap. A weld is placed around the bushing.

You describe two different procedures you have used to seal the reservoir. In what you describe as "Test Criteria 1," a socket head plug is put into

the bushing with 3 full wraps of tape. With this first method, you state that as the pressure is applied to the reservoir, the endcap starts to expand out. The bushing stretches with the endcap, and as the bushing stretches the threads are pulled away from the plug. The plug must therefore be retightened several times before the required pressure is reached. In your "Test Criteria 2," you state that a rubber grommet or washer is placed on the inside of the bushing and forced to expand to seal the bu shings from the inside. You stated that this method checks the weld but removes the threads from the test. With the second method, you state that there was no failure at over five times the working pressure.

While Standard No. 121 does not specify a particular test procedure for this requirement, the language of S5.1.2.2 makes it clear that a reservoir must "withstand" for 10 minutes a condition where the reservoir is pressurized at the specified level. The refore, in conducting a compliance test, NHTSA would pressurize a reservoir to the specified level. This would necessitate sealing the reservoir.

In considering how a particular reservoir would be sealed, it is important to bear in mind that the purpose of the test is to evaluate the reservoir's structural integrity and ability to withstand pressurization. I can offer you the following comments o n the two alternative test methods you described. The first method (Test Criteria 1) would appear to evaluate a reservoir's ability to withstand pressurization. The threaded plug would appear to reasonably approximate how the reservoir would be sealed i n an actual use situation. I note that the mere fact that the plug needs to be tightened during the test to achieve the specified level of pressure would not indicate a failure but would simply reflect minor air leakage around the plug.

The second method (Test Criteria 2) would not fully evaluate a reservoir's ability to withstand pressurization, since it would, as you recognized, remove the threads from the test, thereby creating an artificial seal. It is our opinion that a reservoir would not be capable of "withstanding" the specified hydrostatic internal pressure if the threads failed under such pressurization. This would represent a structural failure equivalent to a rupture.

I hope this information is helpful. If you have any questions about NHTSA's safety standards, please feel free to contact Marvin Shaw at this address or by telephone at (202) 366-2992.

This responds to your letter asking about brake requirements for trailers used in tractor trailer combinations. I apologize for the delay in our response. You asked whether all such trailers are required to be equipped with "maxi" brakes on one or both axles. You state that a "maxi" brake is found on all road tractors and "sets the brakes automatically when the air pressure gets down to a minimum level." Please note that the term "maxi" brakes ordinarily refers to spring brakes used in parking and e mergency brake applications. I further note that most, but not all, trailers are equipped with spring brakes. I am pleased to have this opportunity to explain our requirements.

By way of background information, under the National Traffic and Motor Vehicle Safety Act ("Safety Act," 15 U.S.C. S1392), the National Highway Traffic Safety Administration (NHTSA) is authorized to issue Federal motor vehicle safety standards applicable to new motor vehicles and items of motor vehicle equipment. NHTSA does not approve vehicles or equipment. Instead, manufacturers are required to certify that their vehicles or equipment meet all applicable standards.

Standard No. 121, Air Brake Systems (49 CFR S571.121, copy enclosed), specifies performance requirements for trucks, buses and trailers equipped with air brake systems. The purpose of the standard is to insure safe braking performance of vehicle under n ormal and emergency conditions.

While Standard No. 121 does not require manufacturers to use spring brakes or any other particular type of brake system, many manufacturers use spring brakes to comply with the standard's requirements concerning parking brake performance (truck, buses an d trailers; see S5.6), emergency brake performance (trucks and buses only; see S5.7), and trailer pneumatic system failure performance (see S5.8). I note that while the requirements of S5.65 and S5.8 apply to most air-braked trailers, S3 of Standard No. 121 excludes some trailers from all of the standard's requirements. In addition, S5.6 and S5.8 specify alternative requirements for some trailers.

I hope this information is helpful. If you have any further questions about NHTSA's safety standards, please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992.

This responds to your letter of March 8, 1994, asking for information about this agency's regulations regarding importation and sale of motor vehicles and motor vehicle equipment.

You intend to import "fiberglass kit cars." The cars may be imported "either disassembled or partially assembled." Your company "will then be providing and/or installing American parts in the U.S. for the major mechanical portions like engines, transmissions, suspension systems, tires, etc."

It appears from your letter that you intend to import, items of equipment, either individually or as part of a larger assembly, which, after entry into the United States, will have the drive train and related components installed that are necessary to complete its manufacture as a motor vehicle. For purposes of this interpretation, it is unimportant whether the equipment is imported as individual items, or assembled into a vehicle lacking a power train.

Some items of motor vehicle equipment are subject to the Federal motor vehicle safety standards (FMVSS). In order to be imported into the United States, they must comply with all applicable FMVSS. Passenger car equipment that must comply includes brake hoses, brake fluid, lamps and reflectors, tires, glazing material, and seat belt assemblies. It is mandatory that all these items (except lamps and reflectors) beat a DOT symbol in order to be imported; the symbol is the manufacturer's certification of compliance with the FMVSS. It is optional for lamps and reflectors to be marked with the DOT symbol. If they are not marked, permissible options include a certification statement attached to the equipment item or on the container in which the item is shipped.

When assembly of the vehicle is completed in the United States, its assembler must satisfy itself that it conforms to all applicable FMVSS and affix a label certifying that the vehicle complies.

I have enclosed a copy of an information sheet for new manufacturers of motor vehicles and motor vehicle equipment. It identifies relevant Federal statutes and this agency's standards and regulations affecting motor vehicle and motor vehicle equipment manufacturers. It also explains how to obtain this agency's safety standards and regulations. If you have further questions we shall be pleased to answer them.

TEXT:

This responds to your letter requesting an interpretation of Federal Motor Vehicle Safety Standard (FMVSS) No. 206, "Door locks and door retention components," as it pertains to the locking mechanism of a so-called "5th" door installed on your limousines . I apologize for the delay in responding. We conclude that the locking mechanism on the 5th door is not prohibited by Standard 206.

Based on your letter and a conversation with David Elias of my office, I understand that you have replaced the extra panel on the right side of a 1993 Lincoln Town Car based limousine with a passenger door (i.e., the 5th door). The door consists complete ly of the original equipment manufacturer's materials and hinges. The 5th door is a supplementary door, and does not replace or effect in any way the two side rear doors with which your vehicles are normally equipped.

When the 5th door is closed, its locking mechanism engages automatically, and the door cannot be opened from the inside or the outside. A solenoid locking mechanism that unlocks the 5th door is located inside the vehicle in a "privacy panel" behind the driver's seat. For the driver to unlock the 5th door, the car must be stopped and the driver must then get out of the car and reach through a window into the area behind the driver's seat. The locking mechanism cannot be reached by the driver while sea ted in the driver's seat, and cannot be reached by the passengers in the rear seats. The 5th door cannot be accidentally opened; unless the locking mechanism has been actively disengaged, the door remains locked. Disengaging the locking mechanism for t he 5th door allows the driver to open the door from the outside, although passengers could push the door open from the inside, as well.

There are two pertinent requirements of FMVSS No. 206 to your situation. First, S4.1.3 (Door Locks) states that:

Each door shall be equipped with a locking mechanism with an operating means in the interior of the vehicle.

In two prior letters, to Mr. Charles Murphy on May 10, 1974, and to Mr. Gary Hackett on April 11, 1988, the agency interpreted S4.1.3 to mean that the locking mechanism must also be OPERABLE from within the vehicle.

The first question to be addressed is whether the 5th door meets the requirement of S4.1.3. We believe the answer is yes, the door is equipped with a locking mechanism with an operating means in the interior of the vehicle that is operable from within the vehicle. The operating means for the locking mechanism is in the interior of the vehicle in that the locking mechanism engages automatically when the 5th door is closed. While the means to

disengage the operating mechanism is not accessible to occupants in the vehicle, Standard 206 does not require the locking mechanism to be capable of being disengaged by an occupant. This is because the purpose of the standard is to minimize the chance that occupants of the vehicle will be ejected in a collision. Thus, the thrust of the standard is to ensure that occupants are retained within the vehicle, such as by requiring doors to have door locks that occupants are capable of locking.

The second pertinent requirement is S4.1.3.2 (Side Rear Door Locks), which states that:

... when the locking mechanism is engaged both the outside and inside door handles or other latch release controls shall be inoperative.

The 5th door appears to comply with S4.1.3.2, in that it cannot be opened from the outside or inside when the locking mechanism is engaged.

In a letter to Ms. C.D. Black, dated April 10, 1987, the agency interpreted a question on child safety locks that is relevant to your situation. The child safety lock operated as a "secondary locking system" that, when activated, rendered the inside rea r door handle incapable of opening the door. (It had no effect on the outside door handle.) As we stated in that letter, our conclusion was that Standard 206 permitted the child safety lock because the standard prohibits only secondary locking systems that interfere with the ENGAGEMENT, but not with the DISENGAGEMENT, of the primary locking system. In that letter, we wrote:

The answer to your question about the child locking systems is dependent on whether the systems interfere with an aspect of performance required by Standard No. 206. We have determined that the answer is no, because the requirements of... S4.1.3.2 are written in terms of what must occur when the primary system is engaged and impose no requirements regarding the effects of disengaging the system. Thus, the aspect of performance required by S4.1.3 for the interior operating means for the door locks is that it be capable only of ENGAGING the required door locking mechanisms. The aspect of performance required by S4.1.3.2 for door locks on the rear doors is that the inside and outside door hand les be inoperative when the locking mechanism is ENGAGED. Since we have determined that... S4.1.3.2 do(es) not address the effects of disengaging the required door locks--i.e., S4.1.3.2 does not require that the inside rear door handles b e operative (capable of releasing the door latch) when the required locking system is disengaged--a child locking system may be provided on a vehicle if it does not negate the capability of the door lock plunger (the operating means) to engage the door locks.

I hope this information has been helpful. If you have any further questions, feel free to contact Mr. Elias at the above address or by phone at (202)366- 2992.

This responds to your letter of March 29, 1994, to Mr. Edward Jettner of this agency concerning the dynamic testing requirements of Standard No. 208, Occupant Crash Protection. Your questions concern the application of this standard to a pickup truck ma nufactured in April 1988 with a gross vehicle weight rating (GVWR) of 4,400 pounds. You asked whether the injury criteria in S6 apply to this truck, whether a 35 mph fixed barrier crash test is required, and which sections of Standard No. 208 apply to t his truck.

The safety belt installation requirements for all vehicle types are set forth in Standard No. 208. Section S4.2.1 of standard No. 208 gives vehicle manufacturers a choice of three options for providing occupant crash protection in trucks and multipurpos e passenger vehicles with a GVWR of 10,000 pounds or less, manufactured on or after January 1, 1976 and before September 1, 1991. Option 1, set forth in S4.1.2.1, requires vehicle manufacturers to provide automatic protection at the front outboard seati ng positions, and either meet the lateral crash protection and rollover requirements by means of automatic protection systems or have manual safety belts at the front outboard seating positions such that those positions comply with the occupant protectio n requirements when occupants are protected by both the safety belts and the automatic protection. Option 2, set forth in S4.1.2.2, requires vehicle manufacturers to provide a lap or lap/shoulder safety belt at every seating position, have automatic prot ection for the front outboard seats, and have a warning system for the safety belts provided. Option 3, set forth in S4.1.2.3, requires the manufacturer to install lap or lap/shoulder safety belts at every seating position and to have a warning system f or those belts.

According to your letter, the manufacturer installed Type 2 seat belt assemblies at the front outboard seating positions. This suggests that the manufacturer chose to comply with Option 3. Under this option, the only requirements in Standard No. 208 th at those belts were required to comply with were S7.1, S7.2, and S7.3. The belts were also required to comply with the requirements of Standard No. 209, Seat Belt Assemblies. The manufacturer was not required to certify that the vehicle complied with t he dynamic testing requirements of Standard No. 208. The injury criteria in S6 of the standard are applicable only to vehicles which must comply with the dynamic testing requirements.

Standards No. 208 does not include a 35 mph fixed barrier crash test requirement. The dynamic crash test in Standard No. 208 is barrier crash test at any speed up to 30 mph. NHTSA does perform some 35 mph barrier

crash tests as part of the New Car Assessment Program (NCAP). NCAP is a consumer information program, not a safety compliance test. NHTSA does not test every vehicle under this program. In the 1993 model year program, NHTSA tested 37 new vehicles and released results on 68 additional vehicles which had been tested previously and had not changed significantly in model year 1993.

I hope you find this information helpful. If you have any other questions, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992.

TEXT: Dear Counselor,

Our company has been in business will over 50 years, manufacturing bumper guards for the passenger car, pickup truck and van industry. These products are used in our country and sometimes exported abroad. These products have over the years saved lot s of lives and a lot of money spent towards costs resulting out of collision damage.

There were several competitors in the days when all the auto vehicles had metal and five mile per hour crash bumpers. Now, it appears that (and we have been told by Ford and General Motors) we are the only bumper guard manufacturing company left in a ll the U.S. All the other bumper guards manufacturers have closed down because of lack of market for bumper guards.

Our primary market disappeared when the 2 1/2 mile collapsible plastic or fiberglass bumpers were approved. Now with the introduction of the air bags (Federal Motor Vehicle Standard # 208), our taxi-cab and police car markets are drying up.

General Motors and other auto manufacturers, it appears have advised consumers, taxi-cab and police fleet administrations that if a bumper guard or any other similar device is placed in front of the bumper, it would interfere with # 208 device (the ai r bag) and the car manufacturers guarantees or warranties would then be questionable. This has caused the consumers, taxi-cab and police car administrators enough concern so as to stop buying bumper guards from us. This has caused the taxi-cab bumper g uard market and the police car bumper guard market to reduce substantially and it is now literally drying up. We may be forced soon to close our doors.

We need your prompt assistance, your unequivocal opinion on the issue of whether the attachment of a bumper guard to the front bumper of a vehicle will interfere with Federal Motor Vehicle Standard # 208 devise (air bag device).

Sir/Madam, in our company, except for three employees, the next junior most employee has been with the company for 17 years and the 2 senior most employees have been with the business 43 years and 47 years, respectfully. By closing this business, bel ieve me, we will lose hands-on knowledge and talent that has been the backbone of our country's industrial might!

Please do help us. We are all praying for your prompt response.
