TINTED WINDSHIELDS DON'T INCREASE ACCIDENT RISK

BASED ON A STATISTICAL ANALYSIS OF OVER 6000 ACCIDENTS, IT IS SHOWN: (1) THAT WINDSHIELDS WITH TINTED OR HEAT-ABSORBING (HA) GLASS DO NOT CONTRIBUTE TO ACCIDENT RISK; (2) THE PROPORTION OF NIGHTTIME AND DAYTIME ACCIDENTS OF HA GLASS WINDSHIELDS CORRESPONDS TO THE PROPORTIONS OF VEHICLES EQUIPPED WITH HA WINDSHIELDS; (3) CARS WITH HA WINDSHIELDS ARE NOT INVOLVED IN AN EXCESS OF NIGHTIME ACCIDENTS; AND (4) OLDER DRIVERS USING CARS EQUIPPED WITH HA WINDSHIELDS DO NOT PRESENT AN INCREASED ACCIDENT RISK WHEN DRIVING AT NIGHT. HOWEVER, THE ABOVE CONCLUSIONS DISAGREE WITH THE CONCLUSIONS REACHED BY THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S EARLIER PUBLICATIONS THAT WERE USED IN PROPOSING A STANDARD ON LIGHT TRANSMITTANCE. THIS PROPOSAL WOULD REQUIRE AT LEAST 80% LIGHT TRANSMITTANCE IN THE PRIMARY VIEWING ZONE OF THE DRIVER, THUS EFFECTIVELY RULING OUT THE USE OF HA GLASS IN WINDSHIELDS.
