Dear Mr. Schultz:
This is in reply to your letter of April 4, 1996, asking for an interpretation of Table IV of Motor Vehicle Safety Standard No. 108 as it applies to the location of reflex reflectors on motorcycles.
You point out that agency interpretations permit front turn signal lamps and headlamps "to rotate about the steering axis as long as they are within the location limits specified in the regulation". You ask for confirmation that this interpretation is equally applicable to front side reflex reflectors.
The answer is yes. Table IV requires front side reflex reflectors to be located "on each side. . . as far to the front as practicable." Conformance is determined with the front wheel in the straight-ahead position. The determination of practicability of location is initially that of the motorcycle manufacturer and the National Highway Traffic Safety Administration will not question it unless it is clearly erroneous. Thus, a front side reflex reflector may be mounted on a portion of the motorcycle that turns if the manufacturer determines that that location is as far to the front as practicable, even though, during a turn, that reflector may not be visible from the side of the motorcycle.
If you have any questions, you may refer them to Taylor Vinson of this Office (202-366-5263).
