abstract="Involvements in multiple-vehicle daylight crashes in nine states over 4 years were analyzed for a group of passenger cars and light trucks equipped with automatic daytime running lights. On average, these vehicles were involved in 3.2% fewer multiple-vehicle crashes than vehicles without daytime running lights (P = 0.0074).",
