TEXT:

This responds to your letter of January 8, 1994, asking two questions concerning a recent amendment to Standard No. 217, Bus Emergency Exits and Window Retention and Release (57 FR 49413; November 2, 1992). Your questions and the response to each follow .

1. There's some confusion here in our engineering department regarding the interpretation of the "Daylight Opening" and "Unobstructed Opening" as it applies to the new side emergency door specification in FMVSS 217. Page 2 shows the allowable obstructi on and the context in which "Daylight Opening" and "Unobstructed Opening" are used. Page 3 shows some measurements of our seats placed according to the "30 cm minimum" shown on page 2. Page 4 shows four different interpretations of the "Unobstructed Op ening" area. Depending on the interpretation, between 9 and 15 people may be accommodated by a side emergency door. My question is this: of the four possibilities shown, which definition of the "Unobstructed Opening" area is correct? Mr. Hott indicat ed definition 4.

The term "daylight opening" is defined in the Final Rule as "the maximum unobstructed opening of an emergency exit when viewed from a direction perpendicular to the plane of the opening." An obstruction in this context would include any obstacle or obje ct that would block, obscure, or interfere with, in any way, access to that exit when opened. In determining the "maximum unobstructed opening of an emergency exit," we would subtract, from the total area of the opening, the area of any portions of the opening that cannot be used for exit purposes as a result of the obstruction. The area measurements would be taken when viewed from a direction perpendicular to the plane of the opening.

Your question specifically concerns how the "maximum unobstructed opening" of a side door is measured when the opening is partially obstructed by a seat. In the case of the illustrated door exit, occupants would use the exit by movement along the floor. This would be considered in determining the extent of an obstruction. None of the four examples you enclosed with your letter correctly illustrates the area that would be credited for the illustrated exit. The following regions would not be credited for this exit: (1) the area visually obstructed by the seat; (2) your region A 2, an area bounded by a horizontal line tangent to the top of the seat back, a vertical line tangent to the rearmost portion of the top of the seat, the upper edge of the doo r opening, and the edge of the door forward of the seat; (3) your region A 5, an area bounded by the seat back, a horizontal line tangent to the top of the seat back, and the edge of the door forward of the seat; and (4) your region A 8, an area bounded by the seat leg, the floor, the lower edge of the seat bottom, and the edge of the door forward of the seat. Because the seat would make the last three regions unusable as exit space for a person traveling along the floor of the bus towards the exit, th ey would not be credited for that exit.

You should be aware that the agency published a notice of proposed rulemaking to amend Standard No. 217 on December 1, 1993 (58 FR 63321). The notice proposed two alternate means for determining the maximum amount of area that will be credited for all t ypes of emergency exits on school buses. The agency is currently reviewing the comments received in response to this notice. I am enclosing a copy of this notice.

2. Here is an excerpt from FMVSS 217 S5.5.3(a):

"Each school bus ....shall have the designation "Emergency Door" or "Emergency Exit" as appropriate, .... For emergency exit doors, the designation shall be located at the top of, or directly above, the emergency exit door on both the inside and outside surfaces of the bus.... For emergency window exits, the designation shall be located at the top of, or directly above, or at the bottom of the emergency window exit on both the inside and outside surfaces of the bu s."

I've seen a two-sided sticker used by other bus manufacturers. It is applied on the inside surface of a window and the same image "Emergency Door" or "Emergency Exit" can be read from both inside and outside the bus. Is it permissible for us to use thi s sort of decal, assuming it meets all other (i.e., FMVSS 302)?

The answer to your question is yes. The agency addressed this issue in an October 2, 1978, letter to Mr. E.M. Ryan of Ward Industries, Inc. I am enclosing a copy of this letter.

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

Dear Mr. Hellmuth:

Please find enclosed a request for information related to the conspicuity rule, from a local business in Denver. Since they are requesting an opinion, it is beyond the scope of our office to assist. They have forwarded considerable detail and I hope yo u will be able to be of assistance.

We have had a number of requests for information on the rule, and in most instances sending a copy has sufficed.

Dear Mr. Montgomery:

It will not be possible to answer your "conspicuity" question from our office here in Denver. I have forwarded your letter and pictures to the Office of Vehicle Safety Compliance in Washington, and asked them to respond to your request.

I hope this will provide the information your need and thank you for your interest in highway safety.

3/9/94 LETTER FROM ROBERT MONTGOMERY TO MIKE BAKER:Mr. Mike Baker, State Director Federal Highway Administration Department of Transportation 555 Zang St

Lakewood, CO 80228

REF: 49 CFR Part 571 - Federal Motor Vehicle Safety Standards; Lamps, Reflective Devices and Associated Equipment

Dear Mr. Baker:

I am enclosing two photos. Photo number one depicts the conspicuity stripes as they come from the manufacturer. They are mounted on the Doors at a height of 56 inches which is approximately 6 inches higher than the 1.25 meters (50 inches) dictated. As you can see, it is necessary to offset the rear red and orange logo striping so that the stripes no longer make an even continuous line around the trailer.

Photo number two depicts the rear of an identical trailer where the reflectorized material was installed between and in line with the taillight assemblies. This installation is 46 inches which is 4 inches less than the 1.25 meters (50 inches) dictated. The material DOES NOT extend form the extreme edges of the trailer as in photo number one.

S5.6.1.4.1 allows for "as close as practical" to both height and width.

We would, of course, prefer to equip the rear of our trailers as depicted in photo number two: 1) To avoid the need to offset our red and orange reflectorized striping and 2) to bring the conspicuity striping down more to eye level and in line with the r ear lamps.

The diagram provided in the register does show the reflectorized striping from edge-to-edge but the artist failed to consider the bumper bar area and the light assemblies that are actually on a van and which basically interferes with proper height and wi dth placement on most trailers.

Would it be possible to obtain a written interpretation as to the legality of compliance with the regulation as to the installation of the reflectorized striping shown in photo number two, in a prompt and timely manner.

Thank you. Sincerely,

Robert L. Montgomery, Safety Manager Leprino Transportation Division

TEXT:

This responds to your letter of November 15, 1993, in which you requested an interpretation of the final rule issued by this agency on January 15, 1993, 58 FR 4586, which amended Federal Motor Vehicle Safety Standard (FMVSS) No. 222, School Bus Passenger Seating and Crash Protection to include requirements for wheelchair securement devices and occupant restraint systems.

You referred to the second sentence in S5.4.3.2 of the standard which provides in pertinent part: "When more than one wheelchair occupant restraint shares a common anchorage, the anchorage shall be capable of withstanding a force of 13,344 Newtons multi plied by the number of occupant restraints sharing that anchorage." You stated that you believe that this language is intended to address the situation where restraints from two different wheelchair occupant restraint systems share a common anchorage, a nd is not intended to address the situation "where the lower end of an upper torso restraint joins the pelvic restraint and goes to one of the rear floor anchorages of a single occupant's restraint system." You stated that if the latter, the floor ancho rage would be required to withstand a force of 13,344 Newtons each for the upper torso restraint and the pelvic restraint; and if the wheelchair was also secured to that floor anchorage, the anchorage would be required to withstand 3 x 13,344 Newtons.

Your letter included two figures illustrating typical wheelchair securement and occupant restraint system designs. In Figure 1, the upper torso restraint is attached to the lap belt at the buckle, and the lap belt is attached to the vehicle at the same anchorage as the rear anchorage for the wheelchair securement device. In Figure 2, the upper torso restraint is also attached to the lap belt; however, the lap belt is attached to the rear wheelchair securement device instead of the wheelchair securemen t anchorage. You asked for verification that the required load for the rear anchorages for both designs is 2 x 13,344 Newtons rather than 3 x 13,344 Newtons.

You are correct that the load for the rear anchorages for both these designs would be 26,688 Newtons (2 x 13,344 Newtons). The relevant section to determine this load is S5.4.3.2(e) which states:

When a wheelchair securement device and an occupant restraint share a common anchorage, including occupant restraint designs that attach the occupant restraint to the securement device or the wheelchair, the loads specified by S5.4.1. 3 (13,344 Newtons) and S5.4.3.2 (13,344 Newtons) shall be applied simultaneously...

The term "wheelchair occupant restraint" includes both the pelvic and upper torso restraints (see S5.4.4). In your designs, each rear floor anchorage would be required by S5.4.3.2(e) to withstand a combined force of 26,688 Newtons, which includes the lo ad specified for the wheelchair occupant restraint and the load specified for the wheelchair securement device.

The second sentence of S5.4.3.2, which you quoted in your letter, addresses the situation where the wheelchair occupant restraints for more than one wheelchair, e.g. two wheelchairs, are secured to the same floor anchorage. This requirement parallels a r equirement in S5.4.1.3 which addresses the situation where the wheelchair securement devices for more than one wheelchair are secured to the same floor anchorage. Thus, for example, if either of your designs were installed in a bus such that the right r ear anchorage was shared with another identical wheelchair securement and occupant restraint system (functioning as the left rear anchorage for the second system), that floor anchorage must be capable of withstanding a force of 13,344 Newtons for each oc cupant restraint system and 13,344 Newtons for each wheelchair securement system, for a total force of 4 x 13,344 Newtons, such force to be applied simultaneously as required by S5.4.3.2(e).

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

It has come to our attention, new headlamps are being installed on BMWs, 750 models. These lamps are called XENON and are "Hella SSB 352 (lower beam) and Hella SSB 328 (upper beam) with replaceable bulb headlamp with glass lens and plastic reflector.

This office received a complaint from a BMW Dealership indicating an owner of one of these vehicles is being continually stopped by law enforcement because of these headlamps. The reason for concern from the officers, is the intensity of the light beam from these lamps is much whiter and appears to be stronger.

We would like to know if these headlamps are legal for use on motor vehicles. A report was sent to us stating they meet all the requirements of the FMVSS 108. This report was generated by ETL Testing Laboratory in New York.

I would appreciate your response on this subject as soon as possible.

ATTACHMT: Attached to letter dated 5/5/94 from John Womack to Tilman Spingler (A42; Std. 108)

TEXT:

In this paragraph an integral beam headlamp is defined to be an indivisible optical assembly of lightsource, reflector and lens. In the case of High Intensity Discharge Headlamps where the lightsource is comprised of a bulb and associated electronic mod ules, it may in some cases not be feasible to integrate the ignition module and the control module in the headlamp housing because of space limitations. In the letter to TOYOTA of March 1991 these modules were permitted to be separately located, but per manently attached by cable at the time of assembly. When the ignition module is installed inside and the control module outside the headlamp housing they will be connected by a 4-core cable in one design. Are there requirements for this cable concerning indivisibility and integration, for example, may it be of the following? - soft cable, resistant to abrasion? - hard cable, resistant to cutting and abrasion? - armored cable? Maximum voltage on 2 cores will be 130 V AC in the on-mode of the headlamp, on the 2 other cores 400 V AC for 700 msec during ignition of the light source. These voltages are much lower than voltages on ignition cables for motor vehicle engines.

This responds to your letter of February 21, 1994, requesting further clarification of the requirements of S5.5.3(c) of Standard No. 217, Bus Emergency Exits and Window Retention and Release (as amended at 57 FR 49413; November 2, 1992). Section S5.5.3( c) states that "(e)ach opening for a required emergency exit shall be outlined around its outside perimeter with a minimum 3 centimeters wide retroreflective tape." *1 Your letter referenced our July 7, 1993 letter to you in which we stated that S5.5.3 (c) permits interruptions in the tape necessary to accommodate curved surfaces and functional components. You requested confirmation "that retro-reflective tape around the perimeter of the rear of a school bus can be used to satisfy the requirements of S5.5.3(c)."

I cannot interpret the requirements of S5.5.3(c) as you request, since for many, if not most, designs the nearest possible location will be closer than the perimeter of the bus. While we appreciate your concerns about durability if numerous cuts or notc hes are made to accommodate rivets, our July 7 letter stated that manufacturers have the option of placing the retroreflective tape immediately adjacent to the rivets, rather than over the rivets. As an example, from the illustrations you enclosed, it a ppears that it may be possible to apply retroreflective tape outside the rivets adjacent to the lower portions of the door. Thus, that would be the nearest possible location, rather than the perimeter of the bus itself. I note, however, that the illust rations do not provide sufficient detail of all obstructions for us to determine the nearest possible location for each design.

I also note that your letter stated in support of your request that all school buses are required to have a rear emergency exit. While this is true, the type of emergency exit will vary and retroreflective tape at the perimeter of the exit would allow r escuers to immediately know the precise location of the exit. Moreover, retroreflective tape at the perimeter would enable rescuers to immediately know which type of exit is in this location. This information could be vitally important. Because push-ou t windows are not required to have a means of releasing the exit from outside the bus (S5.3.3.2), this information would allow rescuers to quickly determine that they should move to the sides of the bus to locate an exit they can open.

Your letter asked the agency to treat it as a petition for rulemaking if we did not interpret the standard as you requested. You will be notified of our decision to grant or deny your petition.

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

*1 The July 7, 1993 letter also stated that the agency planned to issue a correction notice of the November 2, 1992 rule that would specify a minimum size of 2.5 cm for the tape. This notice has not yet been published. Until the correction is issued, NHTSA will not take enforcement measures regarding tape size against a manufacturer who uses 1 inch wide retroreflective tape.

TEXT:

This responds to your inquiry about whether Standard No. 302, Flammability of Interior Materials (49 CFR S 571.302), applies to your product. You state that you manufacture a "composite assembly acoustical abatement product" that is installed against ve hicle sheet metal and is then covered by carpet, trim, or the instrument panel. You had further questions about testing your product and certifying its compliance if the Standard applies to it. I apologize for the delay in responding.

By way of background information, NHTSA is authorized to issue Federal Motor Vehicle Safety Standards that set performance requirements for new motor vehicles and items of motor vehicle equipment. NHTSA does not, however, approve or certify any vehicles or items of equipment. Instead, the national Traffic and Motor Vehicle Safety Act (The "Safety Act") establishes a "self- certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety st andards. Since Standard No. 302 is a vehicle standard, the manufacturer of the vehicle, and not the manufacturer of the individual component, is responsible for certifying compliance with Standard No. 302. The agency periodically tests new vehicles and items of equipment for compliance with the standards.

Under the Safety Act's authority, NHTSA has issued Standard No. 302 which specifies burn resistance requirements for materials used in the occupant compartment of new motor vehicles. Section S4.1 lists the components in vehicle occupant compartments tha t the vehicle manufacturer must certify as complying with the flammability resistance requirements of paragraph S4.3. The components listed include seat cushions, seat backs, seat belts headlining, convertible tops, arm rests, all trim panels including door, front, rear, and side panels, compartment shelves, head restraints, floor coverings, sun visors, curtains, shades, wheel housing covers, engine compartment covers, and any other interior materials, including padding and crash deployed elements, tha t are designed to absorb energy on contact by occupants in the event of a crash. Among the listed items that might be applicable to your acoustical abatement product are floor coverings and engine compartment covers. That is, the standard would apply to your product if the acoustical abatement material is a part of one of the covered items and is within 1/2" of the occupant compartment.

You indicate in your letter that you are uncertain whether to test your product to Standard No. 302 as a composite with other materials. S4.2.2 of Standard No. 302 states, "Any material that adheres to other material(s) at every point of contact shall m eet the requirements of S4.3 when tested as a composite...." You indicate in your letter that your product has multiple layers that always

adhere to each other. Accordingly, assuming your product is subject to Standard No. 302, the agency would test your product as a composite material, in accordance with S4.2.2.

Please note that there are other NHTSA requirements that could affect the manufacture and sale of your product. A motor vehicle or equipment manufacturer incorporating your product in its vehicles or equipment would be subject to sections 151-159 of the Safety Act to ensure that its vehicles or equipment do not contain any safety related defect. If the manufacturer or NHTSA determines that a safety related defect exists, the manufacturer would be responsible for notifying purchasers of the defective v ehicle or equipment and remedying the problem free of charge.

In addition, section 108(a)(2)(A) of the Safety Act states: "No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative...any device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable motor vehicle safety standard..." Under this section, the entities mentioned above are required to ensure that the addition of your product would not adversely affect the compliance of any component or element of design on a vehicle with an applicable Federal safety standard. With respect to Standard No. 302, the addition of your product must not reduce the vehicle's overall flammability resistance.

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.

ATTACHMT: Attached to letter dated 8/9/94 from Barry Felrice to Gerald Plante

TEXT: Dear Ms. Gray:

Saab has made some updates to our anti-theft alarm systems in our 1995 model year Saab 900 models. I am sorry I missed your return call. I was hoping we could have had some discussion about NHTSA's current evaluation guidelines on the telephone before submitting written materials. As a way of introduction, I have taken David Raney's place as Saab's Manager of Product Compliance.

Saab views the changes in 1995 components and designs with our anti-theft systems as de minimis ones that would enhance the anti-theft effectiveness of the 1994 alarm. To the extent permitted in 49 CFR Part 543.9, Saab is requesting permission to modify our existing exemption on the Saab 900.

The enclosed material is primarily updates of the material provided to NHTSA on March 25, 1993. Briefly, the changes involve the following:

1. Remote control added. 2. Arming/disarming of alarm/immobilizer functions from remote control only. 3. Remote control operation of the central locking system added. 4. Immobilizer function expanded by adding fuel pump and ignition disengagement to the existing starter motor disengagement.

We would very much appreciate your review of this material to confirm that NHTSA agrees with Saab on the above points. Please feel free to contact me at (404) 279-6377.

Given the definition of "carline" in Part 541.4(b), all 1995 Saab cars labelled as 900 models belong to one carline: Saab 900.

The basis of our petition for exemption is the specification of an effective anti-theft system on all Saab 900 models as standard equipment. In addition, this carline will be specified with an anti-theft radio system, which will further reduce the incidence of auto theft involving Saab cars.

Carline Description

1995 Saab 900 Carline: Body Style Model Designation Engine Variant 2-door hatchback 900 Turbo 4 cyl., 16-valve 4-door hatchback 900 6 cyl., 24-valve 2-door hatchback 900 6 cyl., 24-valve 4-door hatchback 900 4 cyl., 16-valve 2-door hatchback 900 4 cyl., 16-valve 2-door convertible 900 Turbo 4 cyl., 16-valve 2-door convertible 900 Turbo 6 cyl., 24-valve 2-door convertible 900 4 cyl., 16-valve

Anti-Theft System Description-MY 1995 Saab 900

The system consists primarily of the following components and functions:

Components

Audible signal device Electronic control module Remote control (2) Lock assembly protective covers Door-mounted switches (4) Hood-mounted switch Hatch/trunk lid-mounted switch Light-emitting diode (LED-system status indicator light) Glass breakage sensor Anti-Theft system window warning label (2) Three circuit disengagement relay (starter motor, fuel pump, and ignition)

Functions

Central door/lock/unlock from driver and front passenger door locks Dead-bolt locking of all doors and hatch/trunk lid from driver's door lock Starter motor, fuel pump, and ignition disengagement with alarm activation Horn sounding with alarm activation. Turn signal indicator flashing with alarm activation Arm/disarm from remote control Hatch/trunk lid lock/unlock and temporary disarming of the alarm from the remote control

Attachment I contains a wiring diagram depicting the Saab 900 anti-theft system circuitry and electric/electronic components. Attachment II depicts the location of the above-listed components. The vehicle depicted is the Saab 900 four-door hatchback. The two-door hatchback and convertible is identical to the four-door version, with the exception of the added rear passenger doors. Locking features for the rear passenger doors are identical to the front passenger locking features. The two-door convertible differs from the two-door hatchback only in that it has a conventional trunk, which is isolated from the passenger compartment by the rear seatbacks.

Functional Description

From the driver's, or front passenger's door lock, using the ignitiiion key or the remote control, the operator may activate or deactivate the central locking system by turning the key 45 degrees clockwise or counter-clockwise, respectively. In the locked position, all doors, including the hatch/trunk lid, are electro-mechanically locked. It is not possible to lock the doors while they are open (The lock plunger will not depress while the door is open); doors can only be locked from outside when the door is closed by using the ignition key in the door lock or the remote control.

From the dirver's door lock only, if the key is turned an additional 45 degrees in the same direction and withdrawn from this position, the dead-bolt is activated. This means that the door handles and lock devices are disengaged in the locked position, forcing an intruder to crawl through a broken window in order to enter the vehicle. The operator can not activate or deactivate the dead-bolt feature from the remote control.

From the left button on the remote control only, the alarm and immobilization features are armed. In armed condition, the vehicle doors, hatch/trunk, hood and windows are protected by the alarm system. If an attempt is made to enter the vehicle, an audible signal device (105-118 decibels) will sound for 30 seconds and the turn signals will flash for 300 seconds. If the alarm is disarmed within 30 to 300 second period, the horn is interrupted and the turn signal indicators cease flashing. If another trigger signal occurs (e.g., trunk) during this 30 or 300 second period, each function resets for another 30 or 300 second period, from the moment of retriggering.

At the same time, the starter motor, the fuel-pump and the ignition systems are automatically disabled for 30 minutes. If a renewed attempt is made to enter the vehicle, all systems will again react as described above. The anti-theft alarm can be disarmed idefinitely from the left button on the remote control, or temporarily from the hatch/trunk lid, using the right button on the remote control. In the latter case, the alarm rearms automatically ten seconds after the hatch/trunk lid is again closed.

In addition to the active systems described above, several passive anti-theft features further deter vehicle entry and theft. All door lock mechanisms are covered, and recessed inside the door, making it extremely difficult to unlock a door using an instrument slid down between the window and outer door skin. Furthermore, because the latch mechanism is located in the door, rather than in the B-pillar, it is much more difficult to unlatch the door using an instrument slid in between the door and B-or C-pillar. Also, the interior door lock plungers are of a design that is impossible to snag with a wire inserted between the weatherstip and window glass.

Functional Description continued

The Saab 900 ignition key and keylock, which is used to activate and deactivate the anti-theft system, are of a design unique to Saab, and are virtually impossible to "pick". The ignition key is also difficult to duplicate on the open market as a special blank, special key outlining equipment, and access to Saab key codes are required. Key blanks and codes are protected within the Saab corporate and dealer network.

The radio is designed to be extremely difficult to remove without the use of a special extraction tool. Once disconnected from a power-source, the radio will not function again unless a unit-specific, four-digit access code is keyed in. The radio facia is also an uncommon size, making it impractical to install in a different model vehicle.

A dash-mounted LED is used to indicate the various states of the alarm as follows:

1. Arming: The LED is lit for ten seconds.

2. Disarming: The LED is lit for one second.

System triggered during arming procedure: The LED Blinks at half-second intervals for 10 secons.

4. System triggering input cancelled during arming procedure: The LED stops blinking, and remains lit for 10 seconds.

5. Disarming from hatch/trunk lid: The LED is lit for 10 seconds after unlocking the hatch/trunk lid, and again for 10 seconds after closing it.

6. Glass breakage sensor override switch (M95) activated (ignition on): Teh LED is off.

7. Glass breakage sensor override switch (M95) pressed continuously (ignition off): The LED blinks at half-second intervals for 10 seconds.

8. Glass breakage sensor, override switch (M95) activated (ignition off): The LED blinks at half-second intervals for 10 seconds.

9. Disarmed system: The LED is off.

10. Armed system: The LED blinks at 2 second intervals until the system is disarmed.

11. Activated system: The LED blinks at 2 second intervals until the system is disarmed.

12. Self-armed three circuit disengagement: The LED blinks at 2 second intervals until the system is disarmed.

The system is protected against false activation from such common occurrences a shaiking or knockng, sound wave vibration, air turbulence, and temperature or light changes. In addition, the anti-theft system is equipped with a self-diagnostic system, which initiates a 10 second self-check function each time the system is armed. If a failure is detected, a fault code is stored, and the LED will blink for 10 seconds after arming the alarm (rather than remaining steadily lit for 10 seconds) as long as the code is left in the memory. Other system functions remain undisturbed. Diagnostic communication with the electronic control moduel can be initiated through the use of a special Saab Electronic diagnostic scanning tool when the alarm is unarmed.

TEXT:

This responds to your letter of January 31, 1994, requesting an interpretation of whether a 15-passenger Ford Econoline Wagon would be considered a school bus. "The client requesting the vehicle is a mental health and substance abuse facility handling a dolescents on a full-time on-site basis. There is a school located on the premises, since the children reside at the location. The vehicle's purpose would primarily be used for miscellaneous transportation of juvenile patients and facility personnel, b oth on and off campus, as opposed to providing commuting services to and from home."

I am pleased to have this opportunity to clarify our requirements for school buses. The National Highway Traffic Safety Administration (NHTSA) has the authority under the National Traffic and Motor Vehicle Safety Act (the Act) to issue motor vehicle saf ety standards that apply to the manufacture and sale of new motor vehicles, including new school buses. NHTSA defines "school bus" as a motor vehicle designed for carrying 11 or more persons, including a driver, which "is likely to be significantly used for the purpose of transporting primary, preprimary, or secondary school students to or from such schools or events related to such schools." It is a violation of Federal law for any person to sell or lease any new vehicle that does not comply with all school bus safety standards if they are aware that the purchaser intends to use the vehicle as a school bus.

Whether you are required to sell or lease a certified school bus to your client depends on the anticipated use of the vehicle. The mental health and substance abuse facility operated by your client is not a school, however, it does operate a school on t he premises. If your client were to purchase or lease a new bus to be used solely for transporting students to athletic events at other schools, it would be a violation of Federal law for you to sell or lease them a new vehicle that is not a school bus. This is because the vehicle would clearly be significantly used as a school bus. On the other hand, it is not a violation of Federal law for you to sell or lease them a new vehicle that is not a school bus if your client will use the vehicle for gener al purposes, even though such vehicles may be used occasionally to transport students to school- related events. Your letter states that the vehicle would be used for "miscellaneous transportation." If a significant portion of that use would not be tra nsportation of students to school-related events, you are not required to sell or lease a school bus.

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

DATE: April 1, 1994

FROM: John Womack -- Acting Chief Counsel, NHTSA

TO: R. Mark Willingham, Esq. -- Thornton, Summers, Biechlin, Dunham & Brown, L.C. (Austin, TX)

TITLE: None

ATTACHMT: Attached to letter dated 2/1/94 from Mark Willingham to John Womack (OCC 9640)

TEXT:

This responds to your February 1, 1994, letter to me about the National Highway Traffic Safety Administration's (NHTSA's) consumer information regulation for utility vehicles (49 CFR 575.105, Utility Vehicles). The regulation, Part 575.105, requires man ufacturers to permanently affix a prescribed sticker in a prominent location of each utility vehicle to alert drivers of the handling differences between utility vehicles and passenger cars.

You asked about the meaning of the word "permanent" as used in Part 575.105. In a May 1984 final rule establishing Part 575.105 (copy enclosed), NHTSA said that the label "should be of a permanent nature" and concurred with a comment on the proposed rule that the label should be permanently affixed so that, among other reasons, subsequent vehicle owners are made aware of the utility vehicle's handling characteristics. NHTSA believed specifying precisely how the label is to be permanently affixed would be design restrictive. However, we stated in the enclosed final rule that stickers such as the placard required by paragraph S4.3, Federal Motor Vehicle Safety Standard No. 110, Tire Selection and Rims, would be considered adequate.

You also asked "to whom is Part 575.105 directed (i.e., manufacturer, distributor, dealership)...(or) a seller of a used vehicle." The regulation applies to the manufacturer and seller of a new vehicle, not to a seller of a used vehicle. The regulation was issued under sections 103, 112 and 119 of the National Traffic and Motor Vehicle Safety Act of 1966, 15 U.S.C S1381, et seq. (hereinafter Safety Act). Section 103 authorizes NHTSA to issue and amend Federal motor vehicle safety standards for new mo tor vehicles and new items of motor vehicle equipment. Section 112(d) (15 U.S.C. S1401(d)) authorizes NHTSA:

"(T)o require the manufacturer (of motor vehicles and motor vehicle equipment) to give such notification of such performance and technical data as the Secretary determines necessary to carry out the purposes of this Act in the followi ng manner --

(1) to each prospective purchaser of a motor vehicle or item of equipment before its first sale for purposes other than resale . . .; and

(2) to the first person who purchases a motor vehicle or item of equipment for purposes other than resale . . . .

Section 119 confers general rulemaking authority to issue rules to effectuate the express grants of authority and the obligations imposed by the Safety Act.

Sections 103, 112, and 119 of the Safety Act authorize NHTSA to require the consumer information label up to the delivery of the new vehicle to the consumer who first purchases the vehicle "for purposes other than resale." NHTSA cannot require sellers of used vehicles to restore missing labels prior to sale of the used vehicles, or prohibit a vehicle owner from removing or defacing the label.

You also asked for documents regarding the drafting and interpretation of Part 575.105. Please find enclosed copies of the following: Notice of Proposed Rulemaking, dated December 30, 1982 (47 FR 58323); final rule, dated May 11, 1984 (49 FR 20016); fi nal rule, response to petitions for reconsideration, dated August 10, 1984 (49 FR 32069); and letter to Lawrence F. Henneberger, Esq., dated August 15, 1984. For future reference, copies of NHTSA's interpretation letters can be obtained from the agency' s docket section. The address for the docket is 400 Seventh St., S.W., Room 5108, Washington, D.C., 20590, telephone (202) 366-4949.
