Intersections & Right-of-WayStandalone practice
A storm has cut the power, and the traffic signals at a busy intersection are completely dark. No officer or flagger is there. What must you do?
A approaches an intersection with all traffic-signal lenses dark and no officer or flagger present.
Correct answer: Stop, and treat the intersection as an all-way stop
Why
After you stop, the first vehicle to stop goes first, and when two arrive together, the driver on the left yields to the driver on the right. A left-turning driver yields to oncoming traffic. Always follow the directions of an officer or flagger if one is present.
