USAREUR Practice Exam

What must vehicle 3 do before vehicle 1 can turn left?

1. Wait behind vehicle 2

2. Pass in front of vehicle 1

3. Proceed alongside vehicle 2

4. Stop at the intersection

The correct answer is: Pass in front of vehicle 1

The scenario presented suggests that vehicle 1 is preparing to turn left and there are other vehicles, including vehicle 3, involved in the intersection dynamics. For vehicle 3 to allow vehicle 1 to make a safe left turn, it is necessary for vehicle 3 to position itself in relation to vehicle 1 in such a way that does not obstruct the turn. When vehicle 3 passes in front of vehicle 1, it maintains a forward momentum, allowing enough space for vehicle 1 to complete its left turn without interference. This action is crucial because it ensures that vehicle 1 can turn left into the lane created by vehicle 3's movement, as opposed to waiting or stopping, which could potentially lead to confusion or create a traffic stoppage. Other options suggest actions that may not facilitate the left turn efficiently. For instance, waiting behind vehicle 2 could delay the turn, while stopping at the intersection might cause further congestion and confusion. Proceeding alongside vehicle 2 does not directly help create a clear path for vehicle 1 to turn left, which is the main objective in this scenario. Thus, passing in front of vehicle 1 is the most effective option to prioritize safe and efficient traffic flow at the intersection.
