Regulatory, Lane & Parking SignsStandalone practice
You are in the left lane and see this white sign that says LEFT LANE MUST TURN LEFT. Then you see that you want to go straight, but the lane on your right is full. What should you do?

Correct answer: Turn left as the sign requires, then find another way back to your route
Why
Lane-use signs and arrows show which movements are allowed from each lane, and Oklahoma law requires drivers to obey them. Look for these signs early, so that you can move to the correct lane before the intersection. A missed turn costs a few minutes, but a late lane change can cause a crash.
