Advanced left turn arrows are used at signalized intersections when left turning vehicles do not have reasonable opportunities to complete their turn because there are few gaps in approaching traffic and are experiencing unacceptable delays and safety concerns. Overuse of left turn arrows reduces the amount of green time available for all other movements.
