Oklahoma driving lesson · Signs, Signals and Markings
Traffic signals and pedestrian signals
A 3-minute lesson from the Oklahoma course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Traffic signals control vehicles and pedestrians at intersections by granting the right-of-way to each direction in turn. You must obey them, except when an officer is directing traffic: then obey the officer at all times.
Know the rule
Color-blind drivers can tell a signal by position: red on top, yellow in the middle, green on the bottom.
After a complete stop you may turn right on red, and turn left from a one-way street into a one-way street, unless signs forbid it. Yield to all pedestrians and vehicles using the intersection, including bicycles.
In a turning-only lane you must wait for the green arrow. Make only the turn the arrow shows, from the proper lane, and yield to pedestrians in the crosswalk and vehicles legally in the intersection.
Even with a green light, put safety first: yield the right-of-way if it will prevent a collision, even if the other person is wrong. Watch for drivers racing through to beat a red light.
Pedestrians should obey "Walk" and "Don't Walk" signals, when present, instead of the traffic signal. These signals direct people crossing on foot or in wheelchairs.
You're stopped at a red light and want to turn right. Come to a complete stop, check for a sign forbidding the turn, then yield to pedestrians in the crosswalk, bicyclists and cross traffic before turning.
Check your understanding
Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
