What does a stop sign require drivers to do?

A stop sign requires drivers to come to a complete stop. This is a fundamental traffic rule that ensures safety at intersections where visibility may be limited or where traffic flow needs to be managed. When approaching a stop sign, drivers must bring their vehicle to a full stop before proceeding, allowing time to assess the surroundings and the right-of-way of other vehicles or pedestrians.

This requirement is crucial in preventing accidents and ensuring that all road users can navigate intersections safely. The stop must occur at the designated stop line, crosswalk, or intersection if no line is present. This clear stopping rule promotes responsible driving behavior and helps maintain order on the road.

The other options, while related to safe driving practices, do not capture the specific requirement indicated by a stop sign. For instance, slowing down and looking for traffic might be part of the process but does not meet the legal obligation of stopping completely. Yielding to other vehicles is applicable in situations where right-of-way rules are in effect, but it does not replace the necessity of stopping at a stop sign. Proceeding with caution may be wise in various driving scenarios but is not applicable as a standalone response to a stop sign.
