Samenvatting
Windshields, like other components, are subject to wear during the life of the car; windshields wiper action, scraping of ice and the impact of small pebbles while driving will damage the glass. These defects will cause glare, which may be a contributing factor in night- time accidents. An instrument to measure the scattered light from these imperfections was introduced in a preceding paper. The present paper is a report on measurements of the stray light index of cars on the road in selected regions.
