Which vehicle must wait at the junction?

In this scenario, the determination of which vehicle must wait at the junction is often based on traffic rules and the situation depicted in a traffic control context, such as road signs or the right-of-way regulations.

Vehicle 2 is identified as the one required to wait, which suggests that it is either approaching the junction without a clear right-of-way or is in a position where it does not have priority over the other vehicles involved in the situation. This can occur in various scenarios, such as when the vehicle is facing a stop sign, a yield sign, or when it is entering a roundabout or a larger roadway that other vehicles are already on.

The other vehicles, depending on their positions, may either be in a better position to proceed due to having the right of way or possibly already on the road without needing to stop. Understanding traffic rules and the specific instructions given in traffic situations helps in identifying which vehicle should yield to allow for a safe and orderly flow of traffic at the junction.
