In what order may the vehicles proceed at the intersection?

The order in which vehicles may proceed at an intersection is determined by right-of-way rules, which are designed to help prevent accidents and ensure a smooth flow of traffic. In this scenario, the correct sequence is 1-2-3, meaning vehicle 1 has the right of way, followed by vehicle 2, and then vehicle 3.

Vehicle 1 is likely in a position where it either has a stop sign yielding to traffic or is already on the main road and does not need to stop. This gives it priority over the other vehicles. Vehicle 2 may be at a stop sign or waiting to merge and can only proceed once vehicle 1 has completed its turn or passage. Vehicle 3, which may be at a different angle or intersection, follows last, indicating it must yield to both vehicle 1 and vehicle 2 before proceeding.

Understanding these right-of-way rules is crucial for safe driving, as they are designed to minimize confusion and potential collisions at intersections. Each vehicle's position and the traffic controls present (such as stop signs or traffic lights) greatly influence who has the right to go first.
