What is an expected behavior of a driver when approaching a stop sign?

Answer: B — Slow down and prepare to stop

When approaching a stop sign, a driver is expected to slow down and prepare to stop. This behavior is fundamentally about safety and compliance with traffic laws. The purpose of the stop sign is to ensure that vehicles come to a complete stop at the intersection, allowing for more effective observation of oncoming traffic and pedestrians. By slowing down and preparing to stop, the driver can assess the situation and make informed decisions on how to proceed safely. This behavior is critical to preventing accidents and ensuring smooth traffic flow at intersections.
