TEXT:

We have received your letter of July 9, 1993, to Taylor Vinson of this Office requesting interpretations of the trailer conspicuity requirements of Federal Motor Vehicle Safety Standard No. 108 Lamps, Reflective Devices, and Associated Equipment.

Your questions are directed towards a 48-foot container chassis, but in a telephone conversation with Mr. Vinson you have explained that a 40-foot container chassis is also involved. For simplicity's sake we shall refer to trailers of both lengths collectively as the "trailer". The gooseneck on the trailer is 8 feet long.

Paragraph S5.7.1.4.2(a) of Standard No. 108 specifies in pertinent part that the side horizontal strip of retroreflective sheeting "need not be continuous as long as not less than half of the length of the trailer is covered." You have asked whether the length of the gooseneck is included in the 50% computation. The answer is yes. The gooseneck is similar to a trailer tongue, and is included in determining the overall length of the trailer for purposes of compliance with Standard No. 108. From the photos you enclosed, we see that retroreflective sheeting has been applied to the gooseneck and the frame rail with approximately the same spacing between segments. If you determine that this configuration meets S5.7.1.4.2(a) without the container load in place, there would be no need to increase the amount of retroreflective sheeting on the trailer behind the gooseneck.

The same paragraph also requires that retroreflective sheeting shall be located "as close as practicable to 1.25 m. above the road surface." You enclosed a photo of a Maersk loaded chassis and note that "because of space limitations, the striping may not be 4 foot (sic) from the road surface." You have asked whether there has been a change in height allowance to compensate for space adjustments. The agency has been petitioned for reconsideration of this specification, and to allow a mounting height as low as the 15 inches originally proposed. We have not reached a determination on this point, and the height remains at 4 feet. However, if the manufacturer of a new trailer determines that something less than 4 feet is "as close as practicable to 1.25 m. above the road surface" with respect to a particular trailer design, it may certify conformance of the trailer with the mounting height requirement on that basis.

Finally, paragraph S5.7.1.4.2(a) requires that the spaces between sheeting be "distributed as evenly as practicable." In a telephone call on July 16, you informed Mr. Vinson that in some instances equal spacing may not be possible because of trailer unit numbers and other identification, and structural characteristics. As we have advised in the preceding paragraph, the

requirement is modified by what is practicable under the circumstances.

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of September 4, 1974, in which you ask several questions regarding the possible manufacture of semitrailers designed to transport people. You state the semitrailers would be pulled by conventional tractors, would have air-operated bus-type side doors, a rear door for emergency exit, seats, handrails for passengers who stand, and windows that open and close. Communication between the passenger compartment and driver would be limited to a horn that the driver can blow and a blinking red light operable by either a passenger or the driver. You ask whether this type of vehicle is legal, whether it is legal to transport passengers in this fashion, and what specific requirements would be required to be built into the trailer.

We would consider the vehicles in question to be trailers under the Motor Vehicle Safety Standards, and consequently subject to the standards applicable to trailers. These standards are Standard No. 108, "Lamps, reflective devices, and associated equipment," Standard No. 106, "Brake hoses" (eff. as to trailers on September 1, 1975), and Standard No. 121, "Air brake systems" (eff. as to trailers on January 1, 1975), at this time. The trailers would, of course, have to be certified as conforming to all applicable standards, in accordance with the Certification Regulations (49 CFR Parts 567, 568).

Many States prohibit the transportation of passengers in trailers, and as a consequence NHTSA requirements for crashworthiness and occupant protection have not been made applicable to trailers. These requirements include those for restraint and seating systems, glazing materials, head restraints, and emergency exits. Whether or not State laws prohibiting the transportation of passengers in trailers would apply to semitrailers of this type would depend upon each State's interpretation of its law, and that information should be obtained from the various states. However, should it become a commonly permitted practice for persons to be transported in trailers, this agency would very likely expand its occupant protection and crashworthiness requirements through rulemaking to apply to these vehicles.

The transportation in interstate commerce of passengers for hire also falls within the regulatory authority of the Bureau of Motor Carrier Safety, in the Federal Highway Administration. We have forwarded your letter to that agency, requesting that it respond directly to you regarding the effect of regulations it administers on vehicles of this type.

Yours truly,

James B. Gregory -- National Highway Traffic Safety Administration, Department of Transportation

Dear Dr. Gregory:

A member company is currently evaluating the possibility of manufacturing semitrailers which are detachable from the tractor, that are specifically designed to transport people or personnel. These trailers would be pulled over the Federal highways and would be pulled by a detachable conventional tractor. The trailers would be more or less conventional construction with the following basic specifications:

(1) The trailer would have an air operated bus type side door operated off the tractor air brake system.

(2) The trailer would have a rear door for emergency exit that could be operated from the inside.

(3) The trailer would be equipped with seats and handrails for those passengers standing up.

(4) The trailer would be equipped with windows that could be opened and closed.

(5) There would be no communication between the passenger compartment and driver compartment other than a horn that the driver can blow and a blinking red light that can be operated from either the interior of the trailer or the interior of the tractor.

Specifically, is this type of vehicle legal or is it legal to haul passengers over the highway with a detachable semitrailer of this type, and if it is legal what are the specific requirements that have to be built into the trailer?

We would appreciate receiving your thoughts on this matter.

Sincerely yours,

Burt Weller -- Engineering Manager

Dear Mr. Rogers: Thank you for your letter on your constituent's behalf to former Chie Counsel Frank Berndt asking several specific questions about our motor vehicle safety standards for school buses. I hope this information is helpful to you in responding to your constituent. If you or your constituent need further clarification about how our requirements apply in a specific situation, please let me know.; Your questions were as follows: >>>1. Can a vehicle designed, manufactured, and sold as a truck, eve be considered a 'school bus' unless remanufactured, modified, or converted by a manufacturer or a manufacturer's dealer or distributor and certified as a school bus?<<<; The answer to your question depends on whether you are asking about vehicle being considered a 'school bus' under State or Federal law. Under Federal law, which applies to the manufacture and sale of new motor vehicles, the answer is no. A vehicle is certified only once, when manufactured as a new vehicle. With the one exception discussed below, there is no provision in our statutes or regulations for recertification of a used vehicle which has been modified so that it falls into a different category of vehicles. The National Traffic and Motor Vehicle Safety Act and regulations issued thereunder require manufacturers to classify their new motor vehicles and certify that their vehicles meet all Federal motor vehicle safety standards applicable to the vehicle type. Those determinations are only made by the manufacturer at the time the vehicle is originally manufactured. Since both the physical attributes underlying the vehicle types and the applicable safety requirements differ from type to type, a vehicle can be classified only as a single type. Therefore, a new vehicle manufactured and sold as a 'truck' is certified as meeting our safety standards for trucks and cannot be certified also as a vehicle meeting safety standards for school buses.; Our regulations do not prohibit used trucks from being modified fo pupil transportation purposes. Since our certification requirements apply only to the manufacture or alteration of new motor vehicles, the person performing the modification does not recertify the vehicle as a 'school bus' unless the modification of the vehicle is so extensive as to constitute a manufacture of a new vehicle. For example, a used truck chassis lacking requisite systems required by our regulations might be combined with a new school bus body. The completed school bus would be considered newly manufactured, and would have to be certified as a 'school bus.'; Used trucks which have been modified to carry school children might b considered 'school buses' under State law. State definitions of school buses determine the applicability of school bus operational requirements to vehicles. If the modifications to a truck bring it within a State's definition of 'school bus,' then the vehicle would be considered a school bus under State law and would have to comply with State requirements for school buses in order to be properly used as a school bus in that State.; >>>2. Do Federal Motor Vehicle Safety Standards apply only t manufacturers, their dealers and distributors?<<<; The answer to your question is no, because our motor vehicle safet standards apply to anyone who manufactures, distributes or sells new motor vehicles. Federal law requires manufacturers of new school buses to certify that their vehicles comply with all applicable school bus safety standards. In addition, distributors and sellers of new school buses must ensure that only complying school buses are sold. While new school buses are typically sold by their manufacturers or manufacturers' distributors and dealers, the responsibility to sell complying school buses rests with any person selling new school buses.; The Vehicle Safety Act applies also to persons who perfor manufacturing operations on previously certified *new* vehicles prior to the vehicles' first purchase in good faith for purposes other than resale.; Such persons are considered 'alterers' under our regulations and ar subject to requirements that they certify compliance with Federal Motor Vehicle Safety Standards. Alterers who significantly affect the configuration of a new motor vehicle previously certified to applicable safety standards must certify that the new vehicle, as altered, conforms to all applicable safety standards affected by the alteration in effect on the date of manufacture of the original vehicle or on the date the alterations were completed.; In addition, the Vehicle Safety Act applies to commercial businesse performing operations on *new and used* motor vehicles. Section 108(a)(2)(A) of the Vehicle Safety Act (copy enclosed) states, in part:>>>No manufacturer, distributor, dealer or motor vehicle repair business shall knowingly render inoperative, in whole or 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 . . . .<<<; Thus, the requirements of our motor vehicle safety standards affec those aforementioned parties modifying or repairing new or used motor vehicles, by setting limits on the operations performed on those vehicles. Those persons are prohibited from either removing, disconnecting or degrading the performance of safety equipment installed in compliance with an applicable safety standard. There is no prohibition against an individual owner modifying his or her own vehicle.; >>>3. What is the difference between a tamperer and a modifier as the relate to Federal Motor Vehicle Safety Standards?<<<; Our regulations do not define the terms 'modifier' and 'tamperer. However, the terms are commonly used to describe persons who make changes to vehicles. The term 'modifier' is often used to describe persons making changes to new or used vehicles. As explained above, persons modifying a new motor vehicle prior to its first purchase are considered 'alterers' under our regulations and are subject to requirements that they recertify the vehicle. Commercial parties involved with modifying new or used vehicles are subject also to the 'render inoperative' prohibitions of Section 108(a)(2)(A).; 'Tamperers' often refer to persons modifying or removing safety system or equipment on used vehicles. Commercial parties involved in tampering are subject to the 'render inoperative' prohibitions of Section 108(a)(2)(A). Violations of section 108(a)(2)(A) are punishable by civil penalties up to $1,000 per violation. Again, our regulations do not apply to individual owners modifying their own vehicles. Such modifications, however, would have to comply with State law.; >>>4. Who can make the certification that a vehicle meets applicabl Federal Motor Vehicle Safety Standards?<<<; Under the Vehicle Safety Act, manufacturers of new motor vehicle certify that their vehicles comply with all applicable motor vehicle safety standards. As suggested above, 'alterers' are considered to be motor vehicle manufacturers and therefore are also subject to certification requirements. Alterers certify that the vehicle, as altered, conforms to applicable safety standards affected by the alteration.; >>>5. Does the date of manufacture of a vehicle determine the specifi Federal Motor Vehicle Safety Standards that the vehicle has to meet?<<<; In general, the answer to this question is yes. The date of manufactur is one factor determining applicability of our motor vehicle safety standards. Each motor vehicle manufactured on or after the effective date of a safety standard is subject to requirements of that standard if, of course, the standard applies to that vehicle type. However, as explained above, 'alterers' affecting compliance with Federal safety standards by their alteration may choose the completion date of the alterations as the date by which to certify.; >>>6. Are passenger restraint systems required on school buses with manufacture date prior to April 1, 1977?<<<; In 1974, Congress directed NHTSA to issue motor vehicle safet standards for various aspects of school bus safety. Pursuant to that mandate, we issued Standard No. 222, *School Bus Passenger Seating and Crash Protection*, which requires school buses to provide a passenger restraint system through a concept called 'compartmentalization.' The standard became effective on April 1, 1977, and applies to each school bus manufactured on or after that date. School buses manufactured prior to April 1, 1977, are not subject to compartmentalization requirements.; >>>7. Are there any Federal Motor Vehicle Safety Standards applicabl only to school buses prior to April 1, 1977?<<<; The answer is no. There are three safety standards that we issue exclusively for school buses, i.e., Standards No. 220, *School Bus Rollover Protection*, No. 221, *School Bus Body Joint Strength*, and No. 222, *School Bus Passenger Seating and Crash Protection*. Those standards became effective April 1, 1977.; >>>8. Do school buses manufactured prior to April 1, 1977, have to mee FMVSS No. 217 and FMVSS No. 222?<<<; Standard No. 217 became effective September 1, 1973. School buse manufactured on or after that date and prior to April 1, 1977, had to meet Standard No. 217 *if* push- out windows or other emergency exits were provided. Pursuant to the 1974 Congressional mandate, NHTSA amended Standard No. 217 to require school buses manufactured on or after April 1, 1977, to contain additional emergency exits and set special requirements for those exits.; Standard No. 222 became effective on April 1, 1977. School buse manufactured prior to that date do not have to meet that standard.; Again, please contact my office if you or your constituent have an further questions.; Sincerely, Erika Z.

TITLE: FMVSS INTERPRETATION

TEXT: This responds to your recent letter asking what loading conditions are applicable for purposes of measuring the wheelbase of passenger cars, under the new phased-in passive requirements of Standard No. 208, Occupant Crash Protection. Apparently, the wheelbase of one of Peugeot's vehicles having an independent rear suspension varies as a function of the vehicle loading.

The phased-in passive requirements of Standard No. 208 were based on a determination of the lead time necessary to engineer passive restraints into each size class of automobile. Wheelbase was chosen as a measure to delineate the phasing requirements because it is directly related to vehicle size and because it is a well-defined quantity that does not vary significantly within a given car line.

For purposes of measuring wheelbase, the vehicle is loaded according to the general test conditions of Standard No. 208. These test specifications, including loading, are meant to approximate the likely condition of the vehicle under normal driving circumstances. Since a vehicle having a variable wheelbase will generally carry the same weight as the average automobile of its size, it is appropriate that the wheelbase on such a vehicle be determined under the loading conditions specified under Standard No. 208. Therefore, Peugeot should measure the wheelbase of its vehicle under the loading conditions specified in paragraph S8.1.1(a) of the standard.

Re.: Wheelbase Cutoff Points for FMVSS-208 Application

Dear Mr. Levin:

Certain automobiles with independent rear suspensions have a wheelbase which varies as a function of the vehicle loading. In order to determine the effective date of FMVSS-208 for one of our vehicles, it is necessary for us to know under which loading conditions the wheelbase should be measured. "Curb Weight" as defined in CFR 49, Chapter V, Subchapter A, Part 571, Subpart A, R 571-2 and "Unloaded Vehicle Weight" as defined in 36 F.R. 2511 (Feb. 5, 1971) have been suggested by your staff as the most probable possibilities

We would appreciate receiving a prompt official clarification on this matter.

Dear Mr. Clarke:

This responds to your March 11, 2005, letter regarding installation of certain auxiliary lighting on heavy-duty trucks and truck tractors. Specifically, you ask about installing auxiliary lamps in the vicinity of the front identification and clearance lamps. You also ask about installing auxiliary lamps above or below the surface occupied by front identification and clearance lamps.

The standard relevant to your question is Federal Motor Vehicle Safety Standard (FMVSS) No. 108, Lamps, reflective devices and associated equipment. For vehicles of 80 or more inches in overall width (such as the trucks and the truck tractors described in your letter), Table II of FMVSS No. 108 requires that 3 amber identification lamps (three-lamp cluster) be located as close as practicable to the top center of the vehicle or the cab, with lamps placed 6 to 12 inches apart. The function of this three-lamp cluster is to indicate the presence of a large vehicle on the roadway. Table II also, requires that two amber clearance lamps be located "to indicate the overall width of the vehicle . . . and as near the top thereof as practicable."

Before addressing the auxiliary lamp configurations discussed in your letter, we note that S5.1.3 of FMVSS No. 108 prohibits installation of lamps that would impair the effectiveness of the required lighting, including the identification lamp cluster. The agency has long maintained that highway traffic safety is enhanced by the familiarity of drivers with established lighting schemes, which facilitates their ability to instantly recognize the meaning the lamps convey and respond accordingly. Therefore, the agency previously explained that auxiliary lamps must be located such that they would not interfere or be confused with the lamps required by our standards. For example, in a January 21, 2004, interpretation letter to a confidential party, the agency explained that auxiliary lamps must be located far enough away from the three-lamp cluster, so that they do not impair their effectiveness. In an October 18, 2002, letter to Mr. Weidman, we indicated that two auxiliary lamps located next to the three-lamp cluster would detract from the purpose of the cluster. With this background in mind, we turn to auxiliary lamp configurations described in your letter.

You provided descriptions and illustrations showing several different lamp configurations and asked whether these configurations would be permitted under FMVSS No. 108. Specifically, you describe three configurations consisting of the three-lamp identification cluster, two clearance lamps, and one or more sets of auxiliary lamps located between the clearance lamps and the three-lamp cluster. You ask if all three configurations would comply with FMVSS No. 108. In alternative, you ask that the agency confirm that the auxiliary lamps are permissible, if the distance between the three-lamp cluster and the auxiliary lamps is at least twice the distance that separates each lamp in the cluster.

First, we note that auxiliary lamps located immediately adjacent to the three-lamp cluster would not be permitted by FMVSS No. 108 because they would impair the effectiveness of identification lamps. The purpose of the three-lamp cluster requirement is to signal the presence of a large vehicle to other drivers. The number of lamps, three, is a part of the signal, and additional lamps could make the signal less recognizable.

Second, while we would generally prefer to establish distance requirements through rulemaking, we recognize the need for guidance with respect to the permissible positioning of auxiliary lamps located between the clearance lamps and the three-lamp cluster. We believe that positioning auxiliary lamps at a distance that is at least twice the distance that separates each lamp in the required three-lamp cluster provides sufficient separation not to impair the effectiveness of the three-lamp cluster (see diagram below).

Third, you also asked about installing auxiliary lamps above or below the surface occupied by the three-lamp cluster and the clearance lamps. We note that FMVSS No. 108 does not prohibit auxiliary lamps that are located on a different surface from the three-lamp cluster and the clearance lamps. Specifically, auxiliary lamps may be located on the roof of the truck cab, if the required lamps are located on the sleeper roof above the cab roof. The reverse arrangement is also permissible. In either configuration, the auxiliary lamps are located at a sufficient distance from the required lamps that they would not impair their effectiveness.

Finally, we note that the auxiliary lamps must have the same photometric output and be of the same color as the lamps specified in Table II to avoid impairment. We believe that maintaining color and photometric output consistency is important because, for example, the presence of red auxiliary lamps located next to amber clearance lamps could confuse drivers as to the traveling direction of the vehicle.

If you need further assistance, please contact George Feygin of my staff at this address or at (202) 366-2992.

Sincerely,

Jacqueline Glassman

TEXT: Dear Mr. Peterson:

Thank you for the information on your RP-448 SAF-T-Headrest (P), for attachment to the rear cab window of a light truck. I am particularly interested in your drop tests, showing that a ten pound bowling ball (close to head weight) is sufficiently padded by the headrest to prevent the rear window from breaking when the ball is dropped onto the headrest on the window from 25 feet, i.e., with a contact velocity of 27.3 mph. A rear end collision by a vehicle of like weight would have to be with a velocity difference of about 54 mph for the head to hit the cap rear window at 27 mph, so your device does indeed provide excellent need protection. With the usual tempered glass cap rear window, the glass breaks with a need contact velocity of about 15 mph. T his would be a drop height of a ten pound ball with skin simulation of about 7.5 feet. The ball without the skin simulation would expectedly break the glass at a slightly lower speed. What results did you get?

From our National Accident Sampling System (NASS) in 1985, there were 15,000 rear and collisions requiring towaway invciving 24,000 occupants in light trucks and vans, producing 13,000 estimated injuries, with less than 500 of these being serious injurie s. However, from our Fatal Accident Reporting System (FARS) for 1985, 318 people were killed in light truck and van rear end collisions, although 217 of these were with the occupants in the striking vehicle.

This agency is concerned with the problem of head partial ejection in rear end collisions of light trucks, which at present do not have to have head restraints. As an after-market head protection device, your device appears from the data you have suppli ed, which we have not incependently checked, to be excellent for cealing with the problem of head partial ejection in rearing collisions. If the rear window, and hence the head restraints, are near enough to the head during normal driving, your device w ould also provide significant neck deflection (whiplash) protection.

Sincerely,

TARACO ENTERPRISES, INC. Empire Plaza 27 Empire Drive St. Paul, MN 55103

Dear Mr. Van de North: This responds to your October 9, 1978, letter asking several question concerning the modification and use of vans as school buses.; First, you ask whether your client may purchase a van that transport fewer than 10 passengers, and add passenger seating to it without complying with the school bus safety standards. The answer to your question is yes. The National Highway Traffic Safety Administration regulates the manufacture of motor vehicles. Further, the agency prohibits manufacturers, dealers, repair businesses or distributors from subsequently rendering inoperative compliance of a motor vehicle with the safety standards. However, the agency does not regulate modifications made by vehicle owners on their own vehicles.; Second, you ask whether buses manufactured after April 1, 1977, whic were purchased to transport handicapped adults or other adults can subsequently be used to transport children to and from school even though the buses do not comply with the requirements. The answer to this question is the same as the answer to your first question. The agency regulates only the manufacture and initial sale of these vehicles and does not control the use of used vehicles.; Finally, you ask whether your client may purchase a 15 passenge vehicle and subsequently modify it in such a manner that it carries fewer than 10 passengers without complying with the school bus safety standards. Since the school bus safety standards apply only to vehicles carrying 10 or more passengers, a vehicle carrying fewer than 10 passengers is not required to comply with the requirements.; Although the Federal government's regulations do not prohibit th modifications that you propose in your letter, there are several other considerations of which your client should be made aware.; First, although your modifications do not fall within our authority, i the case of your first and second questions the vehicles may fall within a State's definition of school bus and should comply with the school bus safety standards. Some States will not permit the registration of vehicles for school bus use if those vehicles should comply with the safety standards and do not.; Therefore, you should check the appropriate State office to ensure tha the vehicles you intend to modify can be used under existing State law. Second, there is a potential for increased private tort liability for accidents occurring in vehicles that should comply with safety standards but do not.; Sincerely, Joseph J. Levin, Jr., Chief Counsel
