SIGNALING A hand and arm or directional signal of intention to turn or move a vehicle right or left must  be given continuously during the last 100 feet traveled by the vehicle before turning. As a  safety precaution, the signal may be given from a greater distance when warranted by traffic  conditions or the higher speeds of your vehicle.  Never stop or suddenly decrease the speed of your vehicle without signaling your intentions  for the benefit of the other drivers. Be sure turn signals are clean and free from dust, dirt,  ice, or snow.  Use hand signals when the sun is shining brightly or when a line of cars following you could  obscure your turn signal light. Be sure that all turn signal lights are clean and free from dust,  dirt, ice, or snow.  Alaska law requires you to cancel your directional signal light after you use it. Your  unintended signal still means you are turning to the other drivers. You might tempt another  driver to turn or drive across in front of you. Failure to signal is dangerous and inconsiderate. Your signal alerts other drivers to your  actions.  Bicyclist are also required to use hand signals to signal a turn.  When towing triples per 13 AAC 04.205 (e) No person may operate a motor vehicle on the  roadway towing more than one vehicle unless the towing vehicle weighs more than 15,000  pounds, has three or more axles, and is equipped with an air brake system for both the  towing and towed vehicles.
