ATTACHMT: Attached to letter dated 7/7/93 from John Womack to Larry Kness (A41; Std. 101; Std. 108)

TEXT:

Chance Coach is a manufacturer of transit buses, and we are soliciting a written interpretation of two parts of FMVSS 101.

First, S5.1 divides specific motor vehicle controls into three categories: hand-operated controls, foot-operated controls, and displays. If a specific control is furnished, then is it required to be operated per the category's operation? For example: the turn signal control would be hand-operated, the service brake would be foot-operated and the highbeam control could be either hand- or foot-operated. Or should S5.1 be interpreted to mean: if a control is furnished and it is operated in this manner (hand- or foot-), then the following sections of S5.2 and S5.3 apply?

Currently, the turn signal controls of transit buses are mounted to the floor. This position has been used in the transit bus industry since FTA (then UMTA) issued the BASELINE ADVANCED DESIGN TRANSIT COACH SPECIFICATION (referred to as the "White Book"). As stated in the White Book, the turn signals are to be foot-operated momentary contact switches. Do foot-operated turn signals meet S5.1 of FMVSS 101?

A second interpretation is required on S5.3.3 of FMVSS 101. In a transit bus, the furnished controls are located on the dash, and they are illuminated by back lighting their identification. A dimmer switch provides illumination of the identifications over a continuous range. Typically, the windshield wiper/washer controls are provided by a vendor, and they are also installed on the dash. The windshield wiper/washer identifications are located on the control knobs, and they are not backlit. At night, the control knob's identifications are barely discernible from the indirect lighting coming from the other identifications and displays, and very discernible by turning the overhead driver's controlled light on. Does this comply with S5.3.3 of FMVSS 101?

Please contact me at (316) 941-1614, if additional information is needed.

TEXT:

The Motorcycle Industry Council (MIC) is a nonprofit national trade association representing manufacturers and distributors of motorcycles, motorcycle parts and accessories, and members of allied trades.

On behalf of its membership, MIC requests an interpretation of FMVSS 123 as it relates to motorcycle side stand retraction.

FMVSS 123, S5.2.4, states that "a stand shall fold rearward and upward if it contacts the ground when the motorcycle is moving forward.", but makes no reference to any compliance test criteria or procedure.

The Society of Automotive Engineers (SAE) has published two recommended procedures related to side stand retraction testing - SAE J1578 "Motorcycle Side Stand Retraction Test Procedure"; and SAE J1579 "Motorcycle Side Stand Retraction Performance Requirements." A third SAE Recommended Practice, J1846, establishes characteristics for the test surface used for testing in accordance with J1578 and J1579. Copies of these SAE documents are enclosed.

MIC's question is: Does a motorcycle side stand comply with FMVSS 123 if it passes the SAE J1578 test procedure?

MIC would appreciate your earliest possible response to the above request. Please contact me if there are any questions or if additional information is required.

ATTACHMT: Attached to letter dated 11/18/93 from John Womack to Jason Backs (A41; Std. 108)

TEXT: Recently, I spoke with Patrick Boyd (Room 5307) concerning the conspicuity law and how it will affect the business at which I work. Mr. Boyd suggested that I direct my question to you. Allow me to fill you in on the details. I am an engineer at Travis Body & Trailer in Houston, TX. We manufacture aluminum and steel end dump trailers. We will be required to meet the trailer conspicuity law which becomes effective December 1. The law is very detailed about most aspects of its implementation. However, I would like to be sure that my suggested installation is indeed conforming to the law. The rubrail is the obvious placement for the reflective tape on a dump trailer. However, since our present extrusions have raised ridges on the outer surface, it is not convenient to apply the reflective tape to the rubrail. As the final alternative, we could order three new extrusion dies. This would be quite expensive. Presently, I propose that we apply fifteen separate 18" lengths of the tape (11" red, 7" white, made by 3M) to the side sheet directly above the rubrail and in between each side stake. Using these lengths yields 58% coverage of a 39' trailer. This installation places the tape in full view from a point normal to the side of the trailer. At approximately 30 degrees from normal to the side of the trailer, the edge of the tape begins to be obstructed by the side stake. At 45 degrees from normal to the side of the trailer, 1 1/2" (8.33%) of each 18" section of tape is obstructed by the side stake. At 60 degrees from normal to the side of the trailer, 4" (22.22%) of each 18" section of tape is obstructed by the side stake. At 60 degrees from the normal to the side of the trailer, the tailgate reflective tape is in view. This placement of the tape in a slightly recessed position on the trailer which causes obstruction at large angles from normal to the trailer side is why I question that it conforms to the law. We can comply to the application of the reflective tape on the full width of the tailgate (rear of the tailer) with no question. I would like from you in writing that this specific installation of the reflective tape is in fact in compliance to the law in every respect. This would be helpful to have on file in the future should any of our trailer's conformity to the conspicuity law ever arise. Should any of the drawings depicting the placement of the stickers be unclear, feel free to call me. If you deem that this installation is not in compliance to the full extent of the conspicuity law, please contact me to further discuss our options.

TITLE: Conspicuity

ATTACHMT: Attached to letter dated 11/22/93 from John Womack to Donald W. Vierimaa (A41; Std. 108)

TEXT:

Often a new tank trailer will be sold to a customer who will contract with another party to have a lining installed in the tank. High heat is used to apply this lining. After the lining is installed, the tank trailer is painted. After the tank is painted, conspicuity treatment is applied. The high heat used in the installation of the lining precludes the application of paint and retroreflective sheeting to the tank before the lining is installed.

In addition, non-tank trailers may be sold without conspicuity treatment when the owner wishes to contract the application of special paint and logo schemes.

49 CFR 568.3 defines an incomplete vehicle as one "that requires further manufacturing operations, other than the addition of readily attachable components, such as mirrors or tire and rim assemblies, or minor finishing operations such as painting, to become a completed vehicle."

Is a trailer manufactured after December 1, 1993 and sold without the conspicuity treatment required in FMVSS 108 an incomplete vehicle? If you consider such a trailer to be a completed vehicle, does NHTSA require that the manufacturer furnish the owner with (1) retroreflective sheeting or reflex reflectors complying with FMVSS 108, (2) instructions as to where on the trailer the conspicuity treatment should be installed, and/or (3) instructions on preparing the surface for the application of the conspicuity treatment? Should conspicuity treatment installed by the owner be deemed to be not in compliance with S5.7 of FMVSS 108, is the owner solely responsible for the violation and for bringing the trailer into compliance?

If NHTSA determines that the installation of conspicuity treatment is a readily attachable component and therefore a complete vehicle, can the manufacturer certify that "This vehicle conforms to all applicable Federal motor vehicle safety standards in effect on the date of manufacture shown above" if the trailer is not furnished with the conspicuity treatment required by FMVSS 108?

TEXT:

This responds to your letter and telephone calls about the child seat registration form you are considering. The form is required by S5.8 of Standard 213, "Child Restraint Systems," and is depicted in figures 9a and 9b of the standard.

You ask whether S5.8(c) permits you to place certain additional information in the shaded area on the form. The information is a bar code that you said on the telephone contains information on "date of manufacture, shift, location and serial number for the product that the card represents." You explain that the bar code is desired because it can be automatically scanned, which would avoid possible "mis-keying" of the information into the data record. Further, you state that the bar code has to be surrounded by a slightly larger unshaded "quiet zone" to enable the scanner to record the bar code information. You, are concerned whether NHTSA would conclude that the quiet zone renders a part of the shaded area unshaded.

It is our opinion that a bar code that contains the information you described is permitted in the shaded area (the area outside of the space, for the consumer to fill in). S5.8(c) of Standard 213 specifies the information that must be provided on the form and states the following:

No other information shall appear on the postcard, except identifying information that distinguishes a particular child restraint system from other systems of that model name or number may be preprinted in the shaded area of the postcard, as shown in figure 9a.

The bar code, printed in the shaded area, is permitted by S5.8(c). The information provided by the bar code distinguishes a particular child seat from another of the same model name or number. We consider the quiet zone as part of the bar code since it is needed for the bar code to be reliably read. The quiet zone therefore need not be shaded, since the printed bar code (or any other identifying information permitted by S5.8(c)) itself is not.

Please note that, while the bar code is permitted, the information on the model name or number and date of manufacture must still be in English under S5.8(c). This information must be in English so that a consumer can see that this information has been provided and that only minimal effort is needed to fill out the registration form.

We also wish to note another feature of the form you faxed. Your form has the words "please print" after the instructions to the consumer "just fill in your name and address." "Please print" is not on the form depicted in figures 9a and 9b of Standard 213. In an earlier letter, NHTSA decided

that a minor variation in the wording of a warning expressly specified by Standard 213 was permitted when the change clarified the warning and did not make any substantive change to the warning's meaning. (Letter to Mr. McGuigan, December 18, 1980.) Similarly, "please print" is a minor variation to the wording of the instructions that clarifies the instructions and does not substantively change them. Thus, it is permitted.

I hope this information is helpful. Please call Ms. Fujita at (202) 366-2992 if you have further questions.

TO: Docket Section (Redbook, Standard No. 208)

TITLE: Interpretation of Standard No. 208

TEXT:

At the request of the Office of Vehicle Safety Compliance (OVSC), this provides, for the public docket, an interpretation of the requirements of S7.1.1 and S7.1.1.1 of Standard No. 208, Occupant Crash Protection. OVSC asked us to address whether these sections require safety belts at the driver's position of vans to fit around a 95th percentile male dummy when the driver's seat is in the full forward position. As discussed below, the answer to that question is yes.

The general structure of S7.1.1 through S7.1.1.2 is that S7.1.1 sets forth requirements for seat belt assemblies that apply except as those requirements are modified in S7.1.1.1 and S7.1.1.2. S7.1.1.1 modifies S7.1.1 with respect to the range of people that must be fit, but not with respect to the range of seating positions in which that fit must be provided. S7.1.1 provides:

S7.1.1 Except as specified in S7.1.1.1 and S7.1.1.2, the lap belt of any seat belt assembly furnished in accordance with S4.1.2 shall adjust by means of any emergency-locking or automatic-locking retractor that conforms to S571.209 to fit persons whose dimensions range from those of a 50th percentile 6-year-old child to those of a 95th percentile adult male and the upper torso restraint shall adjust by means of an emergency-locking retractor or a manual adjusting device that conforms to S571.209 to fit persons whose dimensions range from those of a 5th percentile adult female to those of a 95th percentile adult male, with the seat in ANY POSITION, the seat back in the manufacturer's nominal design riding position, and any adjustable anchorages adjusted to the manufacturer's nominal design position for a 50th percentile adult male occupant. . . . (Emphasis added.)

Thus, except as modified in S7.1.1.1 and S7.1.1.2, the lap belt and upper torso restraint of any seat belt assembly must meet all the requirements of S7.1.1. More specifically, the lap belt must adjust to fit persons whose dimensions range from those of a 50th percentile 6-year old child to those of a 95th percentile adult male, and the upper torso restraint must adjust to fit persons whose dimensions range from those of a 5th percentile adult female to a 95th percentile adult male, with the seat in any position.

S7.1.1.1 makes a limited modification to S7.1.1's requirements for seat belt assemblies at the driver's seating position; S7.1.1.2 is not relevant to that seating position. Section S7.1.1.1 provides:

S7.1.1.1 A seat belt assembly installed at the driver's seating position shall adjust to fit persons whose dimensions range from those of a 5th-percentile adult female to those of a 95th-percentile adult male.

S7.1.1.1 is significant in what it addresses and what it does not address. It does address the lap belt for the driver's seating position and as to that belt, the range of occupant sizes which must be fit. For the driver's seating position, the general requirement that the lap belt of any seat belt assembly must adjust to fit persons whose dimensions range from those of a 50th percentile 6-year-old to those of a 95th percentile male is modified by S7.1.1.1 to apply to persons whose dimensions range from those of a 5th-percentile adult female to those of a 95th percentile adult male. However, S7.1.1.1 does not address the range of seating positions in which seat belt fit must be provided and thus makes no change in S7.1.1 with respect to that range.

Therefore, S7.1.1 and S7.1.1.1 together require, for seat belt assemblies at the driver seating position, that the lap belt and upper torso restraint must adjust to fit persons whose dimensions range from those of a 5th percentile adult female to a 95th percentile adult male, with the seat in any position.

The use of the term "any" merits special emphasis. With respect to the requirement that safety belts must fit the specified range of occupant sizes with the seat in "any position," the term "any," when used in connection with a set of items, is specifically defined at 49 CFR 571.4 as meaning the totality of that set of items, any one of which may be selected by the Administration for testing. Therefore, safety belts at the driver's position of vans must fit a 95th percentile male dummy with the seat in all possible positions, including the full forward position.

TEXT:

In a recent letter of interpretation on the trailer conspicuity requirements of Standard No. 108, which are effective December 1, 1993, we informed you that "()f 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 word "without" is incorrect, and should be replaced with the word "with", in accordance with the requirement of S5.7.1.4.2(a) that conspicuity treatment not be obscured by trailer cargo. We are sorry for any inconvenience that this error may have caused you.

Our letter also informed you that we were considering a petition for reconsideration of the mounting height requirements for the conspicuity treatment. On October 6, 1993, the agency published its response to this petition, modifying the mounting height requirement to a range between 15 and 60 inches (375 to 1525 mm). I enclose a copy of the amendment for your information.
