Please remember to make sure your headlights are on, and don't rely on your automatic headlights, or driving lights. We're (barely) seeing way too many vehicles without lights on today. If you have to leave the house, please drive safely as the road conditions are poor. 169.48 VEHICLE LIGHTING. §Subdivision 1.Lights to be displayed.
