Seven automobiles were washed and waxed at four car washes. Photographic determinations were made of the glare produced by the wet or dry waxed windshield in a headlight beam. When wet, the waxed windshields scattered three times more light than in the normal human eye. The wet wax scattering was 24.8 times higher than when dry. No wax residues should be permitted on windshields and the National Highway Traffic Safety Administration should issue a mandatory windshield cleaning requirement after waxing.
七辆汽车在四个洗车场进行了清洗和打蜡。通过摄影测定了前照灯光束中湿的或干蜡处理过的挡风玻璃产生的眩光。湿的时候，打蜡的挡风玻璃散射的光比正常人眼多三倍。湿蜡散射比干蜡时高24.8倍。挡风玻璃上不应留有蜡残留，国家公路交通安全管理局应发布打蜡后强制性的挡风玻璃清洁要求。
