TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of March 20, 1973, to this agency asking about the applicability of paragraph S4.1.2 of Federal Motor Vehicle Safety Standard No. 104 to vehicles other than passenger cars.

Your understanding is correct that the standard establishes wiped area requirements only for passenger car windshields. The NHTSA is engaged in research with the intent of establishing as all-weather visibility standard, combining Standards No. 103 and 104, that would among other things extend the windshield wiped area requirements to vehicles other than passenger cars. However, it is not possible to say when we will issue a rulemaking proposal on this subject.
