What is the correct order for vehicles to proceed according to traffic regulations?

The correct order for vehicles to proceed according to traffic regulations emphasizes the principles of right-of-way and the specific protocols that apply in various traffic scenarios. In this case, the sequence 2-3-1 indicates that Vehicle 2 has a higher priority or is in a position to proceed first, followed by Vehicle 3, and finally Vehicle 1.

Typically, this order reflects common traffic situations such as intersections, where vehicles arriving at the same time must yield according to designated rules. Vehicle 2 might represent a vehicle facing a yield sign or one that is already in the intersection, whereas Vehicle 3 might be on a main road without the need to yield. Vehicle 1, in this context, may be on a lesser road or under conditions requiring it to wait.

Understanding the flow of traffic as stipulated in regulations is essential for maintaining safety and order on the roads, and this sequence correctly follows those traffic laws by prioritizing the vehicles in accordance with established rules.
