At which locations are drivers required to stop their vehicle?

Drivers are required to stop their vehicles at intersections with a stop sign. This is a fundamental traffic regulation designed to ensure safety at intersections, where vehicles cross paths, often without any signals to control right of way. When approaching a stop sign, a driver must come to a complete stop and yield to any other traffic or pedestrians already in the intersection or close enough to pose a hazard.

While other choices discuss various scenarios, they do not represent universal requirements for stopping. For instance, at a yellow traffic signal, drivers should prepare to stop, but it's not an absolute requirement unless the signal turns red. Stopping only on highways ignores the need to stop in numerous other situations, while stopping only when pedestrians are present overlooks the important responsibility of drivers to stop at intersections regardless of pedestrian activity. Therefore, the requirement to stop at a stop sign is a critical rule for maintaining order and safety on the roads.
