A single solid white line across a road at an intersection means that a motorist must _________ for a traffic signal or sign.

• A. Stop behind the line
• B. Stop on the line
• C. Stop before the line
• D. Stop after the line

Answer: (A)

That solid white line across the road at an intersection is the stop line. It marks the exact place where you must halt when you’re waiting for a traffic signal or sign. You should stop behind that line so your vehicle is completely before the boundary, not touching or crossing it. This position keeps you out of the crosswalk and gives you a clear view of the signal and any pedestrians before you proceed when it’s safe. Stopping on the line or after it would place you into the intersection area inappropriately, while stopping farther back than necessary isn’t required—the correct action is to stop behind the line.
