The 2011 TMUTCD contains several changes that affect the design and operation of traffic signals. These changes include the addition of a Flashing Yellow Arrow (FYA) display for permissive left-turn operations. While a 5-section signal face with a circular green may still be used in a shared left-turn signal face, the use of a circular green indication in a separate left-turn signal face for permissive left turns has been prohibited. The flashing yellow arrow (or flashing red arrow) is now the only allowable indication for a permissive left/right-turn in a separate left/right-turn signal face.
