North Carolina (NC) Permit Practice Test

Four vehicles approach an intersection with a 4-way stop at the same time. Car B is ahead of Car A, and both are in the same lane and want to proceed straight across. Car C is across the intersection from Car B and wants to proceed straight as well. Car D is to the right of Car B and wants to make a right turn. Which car must yield?

1. Car A

2. Car B

3. Car C

4. Car D

The correct answer is: Car D

In a situation where multiple vehicles approach a 4-way stop, the rules of right-of-way dictate who must yield to whom. Here, Car D, which is positioned to the right of Car B and intends to make a right turn, must yield to Car B, which is ahead and already in the intersection, as well as to Car A behind Car B. In this context, Car D does not have the right-of-way since it is not directly across from the intersection and is interacting with vehicles that are already lined up to proceed straight through. Vehicles going straight maintain precedence over vehicles wanting to turn, particularly when they are at the same intersection and the vehicles going straight arrived first. By yielding, Car D allows the vehicles that are going straight (Car A and Car B) to proceed safely. This ensures that the flow of traffic remains orderly and further prevents accidents at the intersection. Therefore, Car D must yield to the cars straight ahead.
