USAREUR Driver's License Practice Test

In this scenario, determining whether vehicle 2 must wait at the intersection relies on understanding the traffic rules regarding right-of-way. When there are multiple vehicles approaching an intersection, generally, the vehicle that is already in the intersection or the one that has the right-of-way does not have to wait.

If vehicle 2 is not obstructed by vehicle 1 or vehicle 3 (or does not face any traffic signals or signs indicating that it must yield), it can proceed through the intersection without needing to stop. Factors such as the positioning of the vehicles, whether vehicle 2 has a clear right-of-way, and the absence of any traffic control measures support the notion that it does not need to wait.

The other considerations mentioned in the options—signaling from vehicle 1 or the presence of vehicle 3—are not relevant if vehicle 2 has the right to proceed. Traffic laws prioritize established right-of-way over signals or the actions of other vehicles that may not directly impact vehicle 2's ability to move through the intersection safely. Thus, under the right conditions and rules, vehicle 2 is not required to wait, making this the correct response.
