Scope
Specifies requirements for windshield wiping and washing systems, including minimum wiped areas (Areas A, B, C) of the windshield and minimum wipe frequencies, for passenger cars, multipurpose passenger vehicles, trucks, and buses, so the operator can see sufficiently through the windshield. The required wiped/cleared area defines the driver's usable forward field of view in rain/spray.
