Traffic Signals & Road MarkingsStandalone practice
You drive toward an intersection at 30 mph. The light changes from green to steady yellow while you are still far back and can stop safely. What should you do?
A approaches a steady yellow signal at 30 mph and is far back from the visible stop line.
Correct answer: Stop smoothly before the stop line
Why
If the light turns yellow after you are already in the intersection, do not stop there; continue through and clear it. A flashing yellow light is different: it means slow down and go on with care. South Dakota law does not let you enter the intersection once the light is red.
