Do I need to wait for the red light when making a U-turn at a gap?

[VonCorey]

When making a U-turn at an intersection, you generally need to wait for the red light if turning left at the preceding traffic signal intersection. Typically, U-turns are not allowed. Whether a vehicle can make a U-turn without regard to the traffic signal depends on the actual situation or the relevant signs, markings, or "signal light" instructions on the road section. Some vehicles can make U-turns without looking at the signal light, while others must observe the signal. Relevant information about traffic signals is as follows: 1. Introduction: Traffic signals are lights that direct traffic operation, usually consisting of red, green, and yellow lights. A red light means stop, a green light means go, and a yellow light serves as a warning. 2. Control methods: The most basic control method is timed control at a single intersection. Line control and area control can also use timed control methods, known as static line control systems and static area control systems.
