About This Sign

Lane use control signs indicate the permitted movements from specific lanes. Arrows show whether a lane is for turning, going straight, or both.

Where you will see it

You find lane use control signs over or beside lanes approaching an intersection. The arrows on the sign show what each lane may do, whether turn, go straight or both.

What to do

  • Read the arrows before you pick a lane.
  • Make only the movements the arrows show for your lane.
  • Change lanes early if you need a different movement.

A common mistake

Drivers glance at the sign too late and end up in the wrong lane. They then turn from a lane that does not allow it, which is a violation.

What to remember for the test

Match each arrow to its lane: a turn arrow means turning is allowed, a straight arrow means straight, and an arrow showing both gives both choices.
