What should a driver do if they are at a stop sign and another vehicle is approaching?

At a stop sign, the correct approach is to prioritize safety and the right-of-way rules. When you see another vehicle approaching, the appropriate action is to wait for that vehicle to go first if it is already near the intersection. This is crucial because it helps prevent collisions and ensures that both drivers can navigate the intersection safely.

Traffic laws dictate that vehicles must yield the right-of-way to others that are already in the intersection or are close enough to pose a risk, particularly if they are approaching from the right. Being cautious and allowing the other vehicle to proceed first not only adheres to legal requirements but also promotes safe driving habits. This practice reduces confusion and helps maintain a smooth flow of traffic at intersections.

In contrast, other choices such as proceeding if there is no traffic or only going if the other vehicle is going straight do not account for the full context of traffic interactions and may lead to dangerous situations. Honking the horn before proceeding can also be misguided as it does not guarantee safety and can create unnecessary noise or confusion among drivers.
