What should vehicles do when approaching a "Give Way" sign?

Answer: B — Slow down and yield to oncoming traffic.

When approaching a "Give Way" sign, the correct action for vehicles is to slow down and yield to oncoming traffic. This means that drivers must be prepared to give priority to any vehicles or pedestrians that have the right of way at the intersection. The purpose of the "Give Way" sign is to enhance safety by clearly indicating that traffic must yield the right of way to others. By slowing down, drivers can assess the situation better and make informed decisions about whether it's safe to proceed or if they must wait for other vehicles to pass. This action helps prevent collisions and promotes smoother traffic flow at intersections where visibility may be limited. In contrast, speeding up and proceeding through the intersection can lead to dangerous situations where vehicles collide, particularly if there is oncoming traffic that requires yielding. Coming to a complete stop may not always be necessary unless it is safe to do so or required by other traffic signs. Similarly, proceeding without caution disregards the fundamental principles of defensive driving and can exacerbate conflict situations at intersections.
