What does a steady yellow circular signal require you to prepare for?
Correct answer: C – Stopping because a red signal is about to appear
In North Carolina, a steady yellow signal warns that the related green movement is ending and a red signal will immediately follow. Stop if you can do so safely before entering the intersection. If you are too close to stop safely, continue cautiously rather than accelerating to beat the red light.
