ATTACHMT: Attached to letter dated 6/6/94 from Walter Lavis to John Womack (OCC-10080)

TEXT: We have received your letter of June 6, 1994, with respect to your "Saf-T-Flec" reflectors.

You say that you have been informed by a NHTSA representative that "using the standard DOT approved reflector tape would allow the use of my reflector for the trucking industry." Judging from the red, white, and amber samples you have enclosed, your "ref lectors" appear to be retroreflective tape which adheres to a semicircular aluminum base and is intended for vertical mounting on the side and back of vehicles. Several potential customers have asked whether your concept was "DOT approved", and you have asked for a reply.

The Department of Transportation has no authority to "approve" items of motor vehicle equipment. We advise inquires whether manufacture or use of any particular item of equipment is prohibited or permitted under the Federal motor vehicle safety standard s and associated regulations. However, if an item is deemed permissible, this must not be represented as "approval" by DOT.

Your letter is somewhat unclear as to the intended use and market for Saf-T-Flec. The fact that you have enclosed a highlighted copy of S5.1.1.4 leads us to believe that one application you envision for Saf-T-Flec is as a substitute for original equipme nt side reflex reflectors. This substitution is permitted if the reflective material conforms to Federal Specification L-S- 300 (September 7, 1965) and, as used on the vehicle, meets the performance standards of SAE Standard J594f Reflex Reflectors, Jan uary 1977. Accordingly, if your red and amber samples meet these two requirements, they may be used as the side front, intermediate, and rear reflex reflectors that Tables I and III require on trucks and trailers. However, Standard No. 108 does not all ow sheeting material to be used on the rear of vehicles in lieu of reflex reflectors.

What if your reflectors do not meet the two specifications listed above? In this instance, they may be used as supplementary side reflectors to the reflectors that are

required by Standard No. 108, and you may employ amber devices for this use as well as red and white. As supplementary equipment, they are subject to the Federal restriction only that they not impair the effectiveness of the required reflex reflectors. We do not believe that additional reflectors would have this effect. Supplementary lighting equipment such as additional reflectors is subject to the laws of the individual states. We are not able to advise you as to their acceptability under state la ws. The American Association of Motor Vehicle Administrators (AAMVA) provides opinions on state law. AAMVA's address is 4600 Wilson Blvd., Arlington, Va. 22203.

As you may know, S5.7 of Standard No. 108 requires red and white retroreflective material to be applied to the side and rear of large trailers that have been manufactured since November 30, 1993 (those whose overall width is 80 inches or more and whose G VWR is more than 10,000 pounds). This material may be retroreflective sheeting or reflectors. If sheeting is used, it must meet the photometric specifications of Figure 29. If reflectors are used, they must conform to SAE J594f, and provide specified minimum millicandela/lux at specified light entrance angles. Your initial question indicates that you may be interested in marketing Saf-T-Flec for use as a substitute for the conspicuity materials that conform to Standard No. 108. Manufacturers of con spicuity sheeting certify it with the material in a flat vertical plane (as evidenced by the DOT-C2 marking on your white sample). We have reservations whether the curved red and white Saf-T-Flec devices could meet the photometric specifications of Figu re 29, for sheeting, or J594f and the millicandela/lux specifications of S5.7.2.1(b) or (c) for reflectors. Amber is not one of the specified colors for conspicuity treatment, and could not be used as a substitute.

I hope that this answers your questions.
