What does "STOP" mean on a sign?

Answer: B — Come to a complete stop and proceed when safe

The meaning of a "STOP" sign is clear: it requires drivers to come to a complete stop at the intersection where the sign is located. This action is crucial for ensuring the safety of all road users, including pedestrians and other vehicles. After stopping, a driver must assess the situation and proceed only when it is safe to do so, yielding the right of way as necessary. This rule is foundational in traffic regulation, as it prevents accidents and allows for the orderly flow of traffic at intersections. Understanding this requirement helps drivers to develop their situational awareness and promotes safer driving behaviors overall.
