| Duration: 13:33 This video explains the safety benefits and the technology of retroflectivity -- the property of signs, markings and materials that reflects light from vehicle headlights back to the driver. Excellent visuals depict the effects of lighting (daytime, nighttime, dawn and dusk) and weather (clear, rain, snow, fog) conditions on retroreflectivity. The importance of keeping vehicles in good operating condition, including clean, functioning and properly aligned headlights and functioning taillights and windsheild wipers, is stressed. The video also demonstrates the importance of wearing retroreflective clothing and using lights when engaged in outdoor activities such as roadwork, jogging, walking, or bicycling.
