Regarding traffic signals, who regulates the order of vehicles?

1. The nearest driver

2. Traffic signs

3. The leading vehicle

4. The last vehicle

The correct answer is: Traffic signs

The regulation of the order of vehicles at intersections and on roadways is primarily determined by traffic signs. Traffic signals, such as stoplights and yield signs, are designed to control the movement of vehicles and ensure the safety and flow of traffic. These signals provide clear instructions to drivers about when to stop, when to proceed, and in which direction they may go, thereby establishing an orderly pattern of movement for vehicles. Traffic signs serve as official guidance from transportation authorities, and their adherence is essential for maintaining safety on the roads. In contrast, the other choices suggest reliance on individual drivers or the positioning of vehicles, which could lead to confusion and disrupt traffic flow. Therefore, traffic signs play a crucial role in regulating vehicle order and ensuring effective communication among drivers on the road.
