TEXT:

This responds to your June 23, 1992 letter requesting information on Federal regulations concerning safety belts and seating in vehicles manufactured by your company. These vehicles are the "Mini Trolley," the "Road Train," and the "Trolley Tram." You indicated that these vehicles can be used on the highway and are motorized, licensed vehicles.

I am pleased to have this opportunity to explain our regulations to you. Some background information on Federal motor vehicle safety laws and regulations may be helpful. Our agency is authorized, under the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et sec., Safety Act), to issue safety standards applicable to new motor vehicles and 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-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. The following represents our opinion based on the facts provided in your letter.

NHTSA's safety standards specify different requirements for different types of motor vehicles. Therefore, in order to answer your specific questions, it is necessary to determine how each of your vehicles is classified under our regulations. NHTSA defines a "bus" as "a motor vehicle with motive power, except a trailer, designed for carrying more than 10 persons." Your literature indicates that the "Mini Trolley" has a passenger capacity of 18, and that the power unit of the "Trolley Tram" has a passenger capacity of 22. Therefore, both of these vehicles would be considered a "bus" for the purpose of Federal regulations.

NHTSA defines a "truck" as "a motor vehicle with motive power, except a trailer, designed primarily for the transportation of property or special purpose equipment."

The power unit of the "Road Train" has seating capacity for only one passenger, and the primary use appears to be to draw the coaches. Therefore, it appears that this vehicle is a "truck" for the purpose of Federal regulations.

NHTSA defines a "trailer" as "a motor vehicle with or without motive power, designed for carrying persons or property and for being drawn by another motor vehicle." The coaches for the "Road Train" and the "Trolley Tram" would be considered trailers for the purpose of Federal regulations.

Your specific questions and the answers to each follow. You asked us to answer these questions for vehicles manufactured both before and after September 1,

1991.

1. Our small unit has a GVW of 12,300, we understand that we need seat belts for the driver only, this small unit is an eighteen passenger. Our largest is a thirty-two passenger unit with a GVW of 17,000 lbs.

The safety belt installation requirements are set forth in Standard No. 208, Occupant Crash Protection. This standard specifies requirements based on vehicle type and seating position within the vehicle. Different requirements also apply depending on the GVWR of the vehicle. The discussion which follows is limited to vehicles with a GVWR greater than 10,000 pounds.

As explained below, buses such as the "Mini Trolley" and the power unit of the "Trolley Tram" are required to have, at a minimum, a lap belt at the driver's position; trucks such as the power unit of the "Road Train" are required to have, at a minimum, a lap belt at every designated seating position; and trailers such as the coaches for the "Road Train" and the "Trolley Tram" are not required to have any type of safety belt at any seating position.

The requirements for buses with a GVWR of more than 10,000 pounds are contained in S4.4 of Standard No. 208. Section S4.4.1 gives vehicle manufacturers a choice of two options for providing occupant crash protection in buses manufactured on or after January 1, 1972 and before September 1, 1990. Option 1, set forth in S4.4.1.1, requires vehicle manufacturers to provide an automatic protection system at the driver's seating position that meets the frontal and lateral crash protection and rollover requirements. Option 2, set forth in S4.4.1.2 requires vehicle manufacturers to install a lap or lap/shoulder belt at the driver's seating position. Buses manufactured on or after September 1, 1990 are allowed the same two options, however, S4.4.2.2 specifies that, if a manufacturer chooses to comply with Option 2, the lap belt or pelvic portion of the lap/shoulder belt must have either an emergency locking retractor (ELR) or an automatic locking retractor (ALR).

The requirements for trucks with a GVWR of 10,000 pounds or more are contained in section S4.3 of Standard No. 208. Section 4.3.1 gives vehicle manufacturers a choice of two options for providing occupant crash protection in trucks manufactured on or after January 1, 1972 and before September 1, 1990. Option 1, set forth in S4.3.1.1, requires vehicle manufacturers to provide an automatic protection system at all seating positions that meets the frontal and lateral crash protection and rollover requirements. Option 2, set forth in S4.3.1.2 requires vehicle manufacturers to install lap or lap/shoulder belts at every seating position. Trucks manufactured on or after September 1, 1990 are allowed the same two options, however, S4.3.2 specifies that, if a manufacturer chooses to comply with Option 2, the lap belt or pelvic portion of a lap/shoulder belt must have either an ELR or an ALR.

Standard No. 208 does not apply to trailers. Therefore, the coaches for the "Road Train" and the "Trolley Tram" are not required to have safety belts.

2. As you can see on our Tram specs we do have oak seats, is there a ruling on this at all.

The seating requirements are contained in Standard No. 207, Seating Systems. This standard includes strength requirements for all "occupant seats" in passenger cars, multipurpose passenger vehicles, and trucks, and for the driver's seats in buses, except that the requirements do not apply to side-facing seats. Therefore, the driver's seat in the "Mini Trolley" and the power unit of the "Trolley Tram," and all "occupant seats" in the power unit of the "Road Train" must meet the requirements of Standard No. 207. The standard does not specify that seats must be made of a particular material; therefore, oak seats are permitted if they comply with the standard.

As with Standard No. 208, Standard No. 207 does not apply to trailers. Therefore, the seats in the coaches for the "Road Train" and the "Trolley Tram" are not subject to the requirements of Standard No. 207.

We have one seat on some of our vehicles that we refer to as a jump seat it is located in front of the entrance door, this seats two people and faces the driver. Would the same ruling apply to this seat as for the other passenger seats.

As stated above, Standard No. 207 applies only to the driver's seat in buses such as the "Mini Trolley" or the power unit of the "Trolley Tram." If the jump seat is in the power unit of the "Road Train," and if it is not a side-facing seat, it must meet the requirements of Standard No. 207 if it is an "occupant seat" as defined in that standard.

Section S3 of Standard No. 207 defines an "occupant seat" as "a seat that provides at least one designated seating position." A "designated seating position" is defined at 49 CFR S571.3 as

any plain view location capable of accommodating a person at least as large as a 5th percentile adult female, if the overall seat configuration and design is such that the position is likely to be used as a seating position while the vehicle is in motion, except for auxiliary seating accommodations such as temporary or folding jump seats.

Your letter does not contain enough information to determine whether your seat would be considered an auxiliary seating position. If it is, it is not subject to Standard No. 207.

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.

TITLE: FMVSS No. 216, "Roof Crush Resistance-Passenger Cars", Request for Interpretation

ATTACHMT: Attached to letter dated 9/21/92 from Paul Jackson Rice to Richard Allison (A39; Std. 216)

TEXT:

The Bott Group, Inc. (a Design, Sales & Engineering firm for manufacturers of roof racks (luggage racks), decklid racks and accessories), on behalf of all O.E.M. clients who use our products, requests the Agency render an interpretation of the requirements of Federal Motor Vehicle Safety Standard No. 216, "Roof Crush Resistance-Passenger Cars", while considering the conditions as described herein.

To be specific, The Bott Group requests an interpretation of 1) the proper application and orientation of the test device (S6.2 of this standard) and 2) the distance the test device is allowed to travel (paragraph S4 of this standard), when testing vehicles equipped with roof mounted accessories, such as roof racks (luggage racks).

This accessory neither contributes to nor detracts from the actual strength of the roof panel and would collapse easily upon application of the forces as specified in paragraph S6.3 of the standard. The roof rack examples we present for consideration, in the attached documentation, can be easily removed for compliance testing.

Roof racks are positioned on the roof panel surface to lend aesthetic enhancement to vehicle contours. This could influence the positioning of the test device (per S6.2), as well as render impossible compliance with the maximum allowed travel of the test device (per S4), and thus, not achieve the true objective of the standard.

The Bott Group roof rack designs fall into two unique categories:

1) Four Seasons Style Has adjustable/removable crossbar assemblies with end supports that move fore and aft above the vehicle roof in fixed, outer channels. Refer to Figure 1 on attachment "A".

2) Elevated Siderail Style (with fixed position end supports) Has adjustable crossbar assemblies that move fore and aft above the roof surface by sliding in an elevated, channeled siderail assembly, however, the end supports are in fixed positions on the vehicle roof. Refer to Figure 2 on attachment "B".

Please consider, for instance, the roof rack example in Figure 2 on attachment "B". The fixed position, front end support of the siderail assembly is mounted in the area of the "B" pillar on the roof surface.

Under normal conditions this style of roof rack assembly is not removable during use, but it can be easily removed for testing.

The adjustable crossbar assembly on the roof rack example shown in Figure 1 on attachment "A" (normal forward positioning is also in the "B" pillar area) can:

1) be adjusted to its rearward most position out of the contact area of the test device or,

2) be removed completely or,

3) the entire roof rack assembly can be easily removed for testing.

The Bott Group believes that there are three different test conditions which should be considered. We have illustrated the differences in the positioning of the test device (refer to Figure 3 on attachment "C").

Condition 1- Test conducted without a roof rack installed or the roof rack has been removed and the test device has been positioned as outlined in S6.2. The first point of contact has been established and is indicated (marked "A").

NOTE: Test condition 2 & 3 assumes that the "elevated siderail style" roof rack with the fixed position end supports is used.

Condition 2- Test conducted with a roof rack installed and the test device positioned the same as in test condition-1. Using the first point of contact established in condition-1 (marked "A"), as reference, the test proceeded. The actual first point of contact during this condition was to the fixed end support of the roof rack (marked "B") and this was a considerable distance rearward from the original contact point "A" established in condition-1.

The dimension between point "A" and point "B" varies according to the fore/aft positioning of the fixed end support of the roof rack on the roof surface.

When the first point of contact, "B", occurred, the second item we identified was a gap between the bottom of the test device and the roof surface at point "A". This may not comply with S6.2(c).

Condition 3- Test conducted with a roof rack installed and the test device positioned as outlined in S6.2 to the contact point (marked "B") established in test condition-2. This condition seemed to create three situations.

a) The complete test device is relocated some distance rearward of the original positioning in test condition-1 and its established contact point (marked "A"). This may not provide test requirements per S4, S6.2 & S6.4 of the standard.

b) The positioning of the test device left a gap between the bottom surface of the test device and the surface of the roof at point "A". The test device, not being tangent to the surface of the vehicle roof, when first point of contact occurs, may not comply with S6.2(c) of the standard.

c) With the test device not making contact (not tangent) with the roof surface at point "A" when the required pressure is applied to the test device, as specified in S6.3, a considerable amount of test device travel is required before contact (tangency) with the roof surface point "A" is made. This may cause non-compliance with S4, as measured in accordance with S6.4, of the standard.

The Bott Group requests the Agency's interpretation of which test condition above, number 1, 2 or 3, is correct and thus, satisfies the intent of FMVSS No. 216.

If test condition 2 or 3 is deemed correct, can the additional amount of test device travel, required between first point of contact and the actual contact (point "A") on the roof surface, be added to the "allowed distance" of test device travel when determining compliance with paragraph S4 of the standard?

The Bott Group is concerned for the timeliness of this matter because of the design timelines we work under (several model years in advance) and we would like to thank the Agency, in advance, for its kind, prompt, attention and consideration of this matter.

ATTACHMT: Attached to letter dated 5/25/92 from C.N. Littler to Mary Versailles (OCC 7339)

TEXT:

This responds to your letter of May 25, 1992, concerning possible federal preemption of a bill that has been introduced in the New York State legislature. The bill would require any intercity bus that is operated in the State of New York manufactured on or after July 1, 1993 to be equipped with safety belts at every seating position, unless the bus is operated by a motor carrier which does not operate anually more than 100 days or more than 10,000 vehicle miles within the State of New York. After reviewing the copy of this bill enclosed with your letter, we have concluded that it appears to be preempted by Federal law, to the extent that it requires the installation of seat belts for passenger seats of buses that have a gross vehicle weight rating (GVWR) of more than 10,000 pounds and that are not State-owned vehicles. This conclusion is explained in detail below.

Section 103(d) of the National Traffic and Motor Vehicle Safety Act (the Safety Act; 15 U.S.C. 1392(d)) states:

Whenever a Federal motor vehicle safety standard ... is in effect, no State or political subdivision of a State shall have any authority either to establish, or to continue in effect, with respect to any motor vehicle or item of motor vehicle equipment any safety standard applicable to the same aspect of performance of such vehicle or item of equipment which is not identical to the Federal standard. Nothing in this section shall be construed to prevent ... any State or political subdivision thereof from establishing a safety requirement applicable to motor vehicles or motor vehicle equipment procured for its own use if such requirement imposes a higher standard than that required to comply with the otherwise applicable Federal standard.

Section 103(d) preempts New York's proposed law if that law covers the same aspect of performance as an applicable Federal motor vehicle safety standard, and is different from the applicable Federal standard, with one exception. It would not preempt the law to the extent that the law imposes a higher level of performance upon vehicles procured for use by the State or any of its political subdivisions.

In this case, Standard No. 208, Occupant Crash Protection (49 CFR 571.208) "specifies performance requirements for the protection of vehicle occupants in crashes." (S1 of Standard No. 208). Section S4.4 of Standard No. 208 specifies performance requirements for the protection of bus occupants. Accordingly, there is a Federal motor vehicle safety standard in effect and that standard establishes performance requirements for occupant protection in buses. The question then is whether the proposed New York State law, which

applies to the same aspect of performance, is either identical to Standard No. 208's requirements.

The applicable performance requirements for occupant protection at passenger seats in buses manufactured on or after September 1, 1991, differ, depending upon whether the vehicle has a GVWR of 10,000 pounds or less or a GVWR of more than 10,000 pounds. For buses (other than school buses) with a GVWR of 10,000 pounds or less, S4.4.3.2 of Standard No. 208 requires a lap/shoulder belt to be provided at every forward-facing outboard seating position, and either a lap belt or a lap/shoulder belt to be provided at every other seating position. New York's law, requiring seat belts at every seating position in buses, would not be preempted with respect to these small buses if it were interpreted to require the same types of safety belts as required under Standard No. 208.

With respect to buses with a GVWR of more than 10,000 pounds, manufactured on or after September 1, 1991, S4.4.3.1 of Standard No. 208 requires compliance with either of two options for the driver's seating position, the installation of an automatic restraint or the installation of either a lap belt or lap/shoulder belt, and does not require any type of occupant protection system at any other seating position. NHTSA expressly determined that there is not a safety 'need for safety belts or another type of occupant crash protection at these seating positions. See, 39 FR 27585, July 30, 1974. With respect to these large buses, the New York bill would be preempted to the extent that it requires seat belts to be installed at seating positions other than the driver's seating position.

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.

ATTACHMT: Attached to letter dated 5/18/92 from Timber Dick to Deirdre Fujita (OCC 7293)

TEXT:

This responds to your letter concerning Standard No. 213, "Child Restraint Systems," and the Sit'n'Stroll child restraint system you manufacture. The restraint is designed to be rear-facing for children weighing up to 25 pounds.

Your letter relates to our April 22, 1992 interpretation to Mr. Mark Sedlack regarding rear-facing restraints for children weighing up to 25 pounds. In that letter, I stated that under Standard No. 213, such a restraint could be tested with either the six-month-old or the three-year-old dummy in the agency's compliance tests. I further stated that the restraint must physically permit the dummies to be positioned in accordance with the procedures in S6.1.2.3.1 of Standard No. 213. If the restraint cannot permit the dummies to be so positioned, the restraint cannot be recommended for children weighing more than 20 pounds.

You ask whether we would consider the Sit'n'Stroll as permitting the proper positioning of the three-year-old dummy. The photographs enclosed with your letter show the dummy in the restraint with its legs at a right angle to the torso. The backs of the dummy's heels rest on the standard seat assembly's seat back, about five inches below the top of the seat back.

At the outset, I must note that NHTSA cannot provide you with an unqualified answer on whether your restraint accommodates the three-year-old dummy, because we do not know the details of your design. However, we can offer general guidance on the positioning of the dummy's legs, an aspect of the dummy's positioning that is of particular concern to you.

S6.1.2.3.1(b) and (d) of Standard No. 213 specify the procedure for positioning the three-year-old dummy's legs in the child restraint. S6.1.2.3.1(b) states: "... Extend the legs of the dummy as far as possible in the forward horizontal direction, with the dummy feet perpendicular to the centerline of the lower legs." S6.1.2.3.1(d) states: "...(R)otate each dummy limb downwards in the plane parallel to the dummy's midsagittal plane until the limb contacts a surface of the child restraint system or the standard seat .... Position the limbs, if necessary, so that limb placement does not inhibit torso or head movement in (the standard's dynamic) tests...."

Based on the photographs you enclosed, the Sit'n'Stroll permits the dummy's legs to be positioned as specified in S6.1.2.3.1(b). That is, the legs are extended "as far as possible" in the forward horizontal direction. The standard does not specify whether "forward" is relative to the standard seat assembly or to the child. However, interpreting "forward" as relative to the seat assembly would have the effect of disallowing the use of the three-year-old dummy to test a rear-facing restraint, since the positioning procedures would be inappropriate for the restraint. In the absence of

language in the standard to that effect, we are disinclined to so conclude. Instead, we conclude "forward" as used in S6.1.2.3.1(b) is relative to the child.

Although the Sit'n'Stroll permits the legs to be positioned in accordance with S6.1.2.3.1(b), under S6.1.2.3.1(d) the leg placement must not inhibit torso or head movement during the dynamic tests of the standard. It does not appear that the dummy's legs would inhibit torso or head movement due to the forward (relative to the seat assembly) movement of the torso and head in the dynamic tests. However, we cannot make a definite determination based on the information in your letter.

Please note that it is likely that NHTSA will propose amending Standard No. 213 such that a child restraint designed for use with children weighing up to 25 pounds would be tested with a new array of child test dummies, such as the 9-month-old dummy described in subpart J of our regulations (49 CFR Part 572). It is possible that a future amendment to the standard could specify that a new dummy, such as the 9-month-old, will be used instead of the 3-year-old dummy to test such a child restraint. NHTSA has announced its intention to consider rulemaking on incorporating new dummies, including the 9-month-old, in Standard No. 213 compliance tests. This intention was discussed at length in NHTSA's "Planning Document on Potential Standard 213 Upgrade," July 1991.

I also would like to note our concern with the ability of your restraint to meet Standard No. 213's occupant excursion requirement (S5.1.3.2). S5.1.3.2 states: "In the case of each rear-facing child restraint system, (in a dynamic test) ... no portion of the target point on either side of the dummy's head shall pass through the transverse orthogonal planes whose intersection contains, the forward-most and top-most points on the child restraint system surfaces ...." It appears from your photograph that the restraint's seat back might be too low to enable the restraint to meet S5.1.3.2 in a dynamic test. One means of avoiding any potential compliance problem with the excursion requirement would be for your company to raise the height of the seat back on this child restraint system.

I hope this information is helpful.

This responds to your letter concerning Federal Motor vehicle Safety Standard No. 102, Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect. You asked about the standard's display identification requirements for automati c transmission vehicles without a gear shift lever park position. Your questions are addressed below.

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

Standard No. 102 sets forth the following display identification requirements for automatic transmission vehicles without a gear shift park position:

S3.1.4 Identification of shift lever positions. . . .

S3.1.4.2 Except as specified in S3.1 4.3, if the transmission shift lever sequence does not include a park position, identification of shift lever positions, including the positions in relation to each other and the position selected, shall be displayed in view of the driver at all times when a driver is present in the driver's seating position.

S3.1.4.3 Such information need not be displayed when the ignition is in a position that is used only to start the vehicle.

You asked about several similar designs for shift control consoles. In addition to including a mechanism for shifting the transmission (push buttons or toggle levers), the consoles incorporate a display which lists the particular gear position which has been selected, e.g., "R" for reverse. No other gear positions are shown. In at least some of the designs, the display is an electronic one. You asked about the "acceptability" of providing a label indicating the gear position sequence on the body of the shift control consoler e.g., "1 2 D N R." Drawings provided with your letter indicate that the label would be provided directly adjacent to the gear position display. As indicated above,

section S3.1.4.2 requires identification of shift lever positions, including the positions in relation to each other and the position selected, to be displayed in view of the driver. While your designs do identify the gear position selected, they do not , in the absence of an added label, identify the shift lever positions in relation to each other. The additional label would, however, provide such information.

Section S3.1.4.2 also requires that the specified information be displayed in view of the driver at all times when a driver is present in the driver's seating position (except when the ignition is in a position that is used only to start the vehicle). T he times when display is required includes situations in which the ignition is "off." Since your designs use electronic technology to identify the gear position selected, a vehicle equipped with your design might not meet this requirement, at least in t he absence of a device which activates the display whenever a driver is present. It is our understanding that "permanent" display is not possible with electronic technology, due to battery drain. However, if the gear position display is turned off with the ignition (the most obvious means of avoiding battery drain), this requirement would not be met. This is because the display would not function when a driver is in the driver's seating position (before leaving the vehicle upon entering the vehicle a t a later time) while the ignition is "off".

As you are aware, NHTSA has proposed new requirements for the purpose of facilitating the use of electronic technology. See 55 FR 1226, January 12, 1990. If amendments are adopted based on that proposal, the analysis presented above could change.

Attached is a copy of 54 FR 29042, 7-11-89 and 55 FR 1226, 1-12-90 regarding 49 CFR Part 571 and FMVSS 201 (text omitted).

Rickert to Chief Counsel, NHTSA (OCC 5076); Also attached to Maryland Vehicle Law, sections 22-103 and 104, page 320 (text omitted); Also attached to Maryland Vehicle Inspections procedures regarding m irrors and vehicle glazing, pages 227 and 228 (text omitted)

TEXT:

Thank you for your letter seeking this agency's opinion as to whether the State of Maryland may amend its motor vehicle regulations to permit the installation of aftermarket tinting on motor vehicle windows, for individuals who may desire this for medica l reasons. I am pleased to have this opportunity to describe the legal principles that relate to your question.

The National Highway Traffic Safety Administration ("NHTSA") is responsible for issuing Federal motor vehicle safety standards that impose requirements for specific levels of safety performance for new motor vehicles and motor vehicle equipment. Federal Motor Vehicle Safety Standard No. 205, Glazing Materials (49 CFR S571.205), which has been in effect since 1968, imposes a minimum level of light transmittance of 70 percent in all areas requisite for driving visibility (which includes all windows on pa ssenger cars). The purpose of this requirement is to ensure adequate visibility through the windows, thereby reducing the risk of a motor vehicle crash.

Although Federal motor vehicle safety standards apply directly only to new vehicles and equipment, Federal law also imposes limits on the addition of tinting materials to motor vehicle glazing after vehicles have been purchased by consumers. Pursuant to section 108(a)(2) of the National Traffic and Motor Vehicle Safety Act, 15 U.S.C. 1397(a)(2), manufacturers, distributors, dealers, or motor vehicle repair businesses may not "render inoperative" any equipment or element of design installed in complianc e with a Federal safety standard. Thus, those businesses may not install tinting that reduces the light transmittance of windows covered by Standard 205 to a level below the Federal requirement of 70 percent, since that would make the windows "inoperati ve" within the meaning of Standard 205.

This Federal prohibition is similar to that imposed by section 22-104 of the Maryland Vehicle Law, which provides:

A person may not willfully or intentionally remove or alter any safety device or equipment that has been placed on any motor vehicle . . . in compliance with any law, rule, regulation, or requirement of . . . the United States or of this State . . . unle ss the removal or alteration is permitted by rule or regulation adopted by the (Maryland Motor Vehicle) Administrator.

The "render inoperative" provision of Federal law does not apply to actions by individual vehicle owners. Therefore, each State may regulate the extent to which aftermarket tinting may be applied by vehicle owners to their own vehicles. Thus, although section 22-104 appears to preclude aftermarket tinting by any person if the result would be to reduce the level of light transmittance below 70 percent, Maryland may amend its rules or regulations to permit such tinting by individuals, for medical or any other reasons deemed valid by the State. However, Maryland has no authority to grant any exemptions, including medical exemptions, from the "render inoperative" prohibition of Federal law that applies to commercial entities. Hence, regardless of any p rovisions of Maryland law, no manufacturer, distributor, dealer, or motor vehicle repair business may legally install window tinting film on a vehicle, unless the vehicle continues to comply with the Federal light transmittance requirements.

In adopting Standard 205, NHTSA determined that a minimum light transmittance of 70 percent is necessary to meet the need for motor vehicle safety. This is the same level of light transmittance contained in the Safety Code of the American National Stand ards Institute. If, as your letter suggests, Maryland is considering permitting vehicle owners to modify their vehicles such that their windows will have a lower level of light transmittance, we would urge you to carefully consider the safety consequenc es of such an exemption.

Please let me know if you need any further information on this subject.

I would like your clarification on the School Bus and Motor Vehicle Safety Act amended by congress in 1974. This amendment directed the National Highway Traffic Safety Administration to issue motor vehicle safety standards on specific aspects of school bus safety and apply those standards to all school buses. Under this federal law, a van designed for eleven or more persons is considered a school bus if it is maintained for transporting students to and from school or school-related events.

Does federal law prohibit a school district from using a fifteen-passenger van that does not meet federal safety standards for school buses to transport students to athletic events, extra-curricular activities, and field trips?

Our school district purchased a standard, fifteen-passenger, 1990 Dodge van to transport students to various school-related events. Is the use of this van for transporting students to these events violating federal law? If so, please cite the specific s ection of the law pertaining to this.

I shall look forward to hearing from you at your earliest convenience.

This responds to your request for an interpretation of Federal Motor Vehicle Safety Standard No. 101, Controls and Displays. I apologize for the delay in our response. You asked about the requirements of sections S5.1 and S5.3.3(a) in connection with a n instrument panel illumination intensity control. Your question is addressed below.

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 comply with applicable requirements. The following represents our opinion based on the facts provided in your letter.

As noted by your letter, section S5.1 of Standard No. 101 reads as follows:

S5.1. Location. Under the conditions of S6, each of the following controls that is furnished shall be operable by the driver, and each of the following displays that is furnished shall be visible to the driver. . . .

One of the controls listed under section S5.1 is a hand-operated control for illumination intensity. Thus, under section S5.1, an instrument panel illumination intensity control is required to be in a location where it is operable by the driver.

You also noted that section S5.3.3(a) requires that "(m)earns shall be provided for making controls, gauges, and the identification of those items visible to the driver under all driving conditions." You asked whether, under this section, an instrument panel illumination intensity control is required to be "visible to the driver." As discussed below, section S5.3.3(a) does not apply to an instrument panel illumination intensity control.

Section S5.3.3(a) is one of a number of sections which appear under the heading "Illumination." See section S5.3. Standard No. 101 does not require that all controls be illuminated. Section S5.3.1 sets forth requirements concerning which controls must be illuminated. Section S5.3.3(a) then sets forth additional illumination requirements for the controls which must be illuminated and their identification (as well as for gauges and their identification).

In order to determine whether section S5.3.3(a) applies to a particular

control, the first question is thus whether Standard No. 101 requires illumination for that control. As indicated above, this is covered in section S5.3.1. It provides that, with certain exceptions, the identification required by S5.2.1 or S5.2.2 for a ny control listed in column 1 of Table 1 and accompanied by the word "yes" in the corresponding space in column 4 shall be capable of being illuminated whenever the headlights are activated. (Column 4 of Table 1 includes the heading "Illumination.") Th us, Standard No. 101 requires illumination only for those controls which are listed in Table 1 and have the word "yes" in the column for illumination.

Since an instrument panel illumination intensity control is not listed at all in Table 1, no illumination is required by Standard No. 101 for that control. Given that section S5.3.3(a)'s additional illumination requirements only apply to controls which Standard No. 101 requires to be illuminated, and since no illumination is required for an instrument panel illumination intensity control, the section's requirements do not apply to that control.

I own and operate a small welding shop in southern West Virginia and recently asked for and received information pertaining to the manufacture of utility trailers.

Not being a lawyer, literary professor, or physic, nor being able to afford hiring one, I am unable to interpret the information I received.

I am asking for your help. I need to know what is needed with regard to lighting requirements, brakes, length, width, and any other requirements pertaining to trailers only. I don't need any information relevant to the manufacture of automobiles, truck s, or any other motor driven vehicle, foreign or domestic. (I have already sent for VIN information from SAE.)

I also would like to have this information written in such a way that is easily understood by someone such as myself.

This information would not only be of great benefit to me but potentially to the economy of this depressed region. I have the possibility of manufacturing a great number of trailers, both commercially and for the general public.

Any help that you can provide me with will be greatly appreciated.
