A stop line is a solid white line painted on the road that indicates where vehicles must stop at intersections or before crosswalks. It helps ensure that drivers yield to pedestrians and other traffic, promoting safety on the roads. When approaching a stop line, drivers should come to a complete stop before the line, allowing for better visibility and decision-making. Stop lines are often found at traffic signals, stop signs, and pedestrian crossings. They are part of the broader traffic control system, which includes signs, signals, and road markings, all designed to manage vehicle and pedestrian movement effectively.
