Is it a violation to make a U-turn at a straight green light?

[MacDerek]

Whether making a U-turn at a straight green light is a violation depends on the situation. As long as there is no sign prohibiting U-turns at the intersection, it is not considered a violation, regardless of whether the straight traffic signal is red or green. Regulations on signal passage: The "Road Traffic Safety Implementation Regulations of the People's Republic of China" have corresponding provisions: Article 38 states that motor vehicle signals and non-motor vehicle signals indicate: When the green light is on, vehicles are allowed to pass, but turning vehicles must not hinder the passage of straight-going vehicles and pedestrians; when the yellow light is on, vehicles that have already crossed the stop line may continue to pass; when the red light is on, vehicles are prohibited from passing. Precautions for passage: At intersections without non-motor vehicle signals or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle signals. When the red light is on, right-turning vehicles may pass if they do not hinder the passage of vehicles and pedestrians that have been given the right of way.
