Straight-Through Arrow

A white arrow pointing straight ahead reserves the lane for through traffic; vehicles in this lane must continue forward through the intersection.

A white arrow pointing straight ahead, painted in the lane, designates the lane for through movement at the upcoming intersection. Drivers in this lane must proceed straight; turning out of a through-only lane is prohibited. Choose your lane based on the arrow well before the intersection; once you are in a through-only lane near the stop bar, you are committed to going straight.
