What is the purpose of a stop sign?

The purpose of a stop sign is to require drivers to come to a complete stop before proceeding, ensuring safety at intersections. This regulation is critical in managing right-of-way between vehicles and helping to prevent accidents, especially where visibility may be limited or where pedestrians might be present. By compelling drivers to stop, the sign provides an opportunity to assess the situation at the intersection and proceed when it's safe to do so. This rule is a fundamental part of traffic laws that enhances overall roadway safety for all users.
