Lane Use Signs
Two-Way Left-Turn Lane Sign
The centre lane is reserved for left turns by traffic approaching from either direction.
What to Do
Use it for the intended left turn and watch for opposing vehicles entering the same lane.
A Detail to Remember
The mirrored left-turn arrows identify shared use from both directions, rather than a lane for through travel or passing.
Understanding Lane Use Signs
Lane-use signs work with the road markings. Match the arrow or symbol to your lane before the decision point, and choose a safe route if you cannot change lanes in time.
