Passing target: 80% (32/40)
You drive at 30 mph and are about 150 feet from an intersection when the light changes from green to steady yellow. You can stop smoothly before the stop line. What should you do?
Blue car A is about 150 feet before the stop line at 30 mph as its signal changes to steady yellow. No action is selected.
Correct answer: Stop at the stop line, because the red light comes right after the yellow.
Why
A steady yellow light tells you that the green time is over and a red light is next. If you can stop safely, stop at the stop line; if you are already in the intersection when it turns yellow, continue through with care. Tennessee law requires the yellow to show for at least 3 seconds, but drivers who try to beat it cause many crashes.
