What must drivers do at a stop sign?

At a stop sign, drivers are required to come to a complete stop and yield to traffic. This means that a driver must halt their vehicle at the designated stop line, crosswalk, or intersection, whichever they encounter first, allowing enough time to assess the road conditions and any oncoming traffic or pedestrians. Yielding to traffic ensures that the driver can proceed safely and without causing an accident. This rule is crucial for maintaining safety at intersections, where the likelihood of collisions is heightened, particularly when multiple vehicles may approach from different directions.

Other choices fail to emphasize the importance of a complete stop and proper yielding. Simply slowing down or neglecting to stop unless pedestrians are present does not adequately address the need to check for all traffic conditions, which can lead to dangerous situations. Similarly, ignoring the stop sign when no vehicles are nearby undermines road safety regulations meant to protect everyone on the road.
