Your traffic light is green, but a police officer in the intersection holds up a hand and signals you to stop. What must you do?
A green light in the bottom lens of a traffic signal is shown beside a uniformed police officer holding an open hand toward the viewer.
Correct answer: Stop and follow the officer's directions, even though the light is green
Why
Traffic controls include signals, signs and markings, and also directions from police officers, firefighters, highway flaggers and school crossing guards. When an officer directs traffic, obey the officer and not the signal. If the officer tells you to turn when you want to go straight, you must turn.
