Which vehicle is required to wait at the intersection?

In situations involving intersections, the rules governing right-of-way are essential for ensuring the safety and smooth flow of traffic. The correct answer indicates that both vehicle 1 and vehicle 2 must wait at the intersection. This requirement usually arises when these vehicles are at a stop sign or when they are controlled by a red traffic signal, indicating that they must yield to other vehicles or pedestrians approaching from a different direction or lane.

If vehicle 1 is facing a signal that requires it to stop—or if it has a stop sign—then it must yield to any vehicles with the right-of-way or those already in the intersection. Similarly, if vehicle 2 is in a position where it must yield as controlled by road signs or signals, it too would be required to stop and wait before proceeding through the intersection.

Understanding the hierarchy of traffic control devices, the positions of the vehicles in relation to the intersection, and the specific traffic laws pertaining to yields and stops is crucial for determining which vehicles must wait. This knowledge ensures that drivers can navigate intersections safely without confusion, averting accidents and promoting orderly traffic flow.
