There is a new style of traffic signal being installed throughout the state of Alaska to more efficiently control left turns and improve safety at intersections. Research demonstrates that flashing yellow arrows are more intuitive and safer than the solid green lights that these signals are replacing for motorists that are turning left.

The new signal, a flashing yellow arrow, indicates that a left turn is allowed, but you must yield to pedestrians and oncoming traffic, as oncoming traffic has a green light and the right of way.

Just remember, a flashing yellow arrow means yield to oncoming traffic and pedestrians.
