When it comes to turning left, Michigan drivers will have to learn new habits in order to get it right.
Federal safety officials are requiring that Michigan phase out signals using flashing red lights for left-turning traffic.
The state will replace them with a four-phase system of left-turn arrows.
Left-turn arrows will start with flashing yellow, meaning turn left after yielding to oncoming traffic and pedestrians.
Next is steady green, meaning turn left turn.
That will be followed by steady yellow, meaning prepare to stop or complete the left turn, followed by red -- or stop.
