Driving in Wednesday's storm from the eastern end of St. Paul out to Edina, then a turn north to Brooklyn Center and finally back to St. Paul, several hours and freeways later, I literally saw hundreds of cars and trucks plunging through the sleet and snow without headlights turned on. I wondered whether all of the drivers were unaware of the law that requires headlights in such weather conditions. Then it came to me: One of my vehicles has "auto headlights," but they do not come on in even blinding daylight snowstorms because the dashboard sensor discriminates between night and day. Please folks, especially those of you with vehicles with similar auto headlight sensors, save lives and reduce accidents by manually turning on your lights.
