Your unintended signal still means you plan to turn to the other drivers. Be sure that turn signal lights (front and rear) are clean and free from dust, dirt, ice, or snow.Īlaska law requires you to cancel your directional signal light after you use it. Use hand signals when the sun is shining brightly or when a line of cars following you could obscure your turn signal light. Never stop or suddenly decrease the speed of your vehicle without signaling your intentions for the benefit of the other drivers.
