Which signal tells the driver to stop behind the limit line before the intersection?

• A. Red light
• B. Green light
• C. Yellow light
• D. Stop sign

Answer: (A)

Red light is the signal that tells you to stop behind the limit line. The limit line is the white line across the roadway where you must come to a full stop before entering the intersection. You stay stopped there until the light turns green and it’s safe to proceed.

Green means go when it’s safe. Yellow means you should slow down and prepare to stop if you can do so safely before the line. A stop sign is a regulatory sign that requires a stop as well, but it’s not a traffic signal.
