Do you need to watch the red light at a U-turn gap?

You need to watch the red light at a U-turn gap when making a left turn at the traffic light intersection ahead during a red light. Definition: Traffic signals are lights that direct traffic operation, generally consisting of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to pass, and a yellow light serves as a warning. Traffic signals are categorized into: motor vehicle signals, non-motor vehicle signals, pedestrian crossing signals, directional indicator lights (arrow signals), lane signals, flashing warning signals, and railway crossing signals. Scientific Basis: According to optical principles, red light has a long wavelength and strong ability to penetrate air, making it more noticeable than other signals. Green is used as the permission signal because the difference between red and green is the most distinct, making them easy to distinguish.
After driving for so many years, I've found that at intersections with U-turn gaps, making a U-turn during a red light is generally allowed. I remember once at a major road turn, there was a dedicated U-turn lane. With the red light on, I just gently turned the steering wheel and went through—super convenient. By the rules, as long as the gap is clearly marked and doesn't interfere with straight-moving vehicles or pedestrians, it's fine. But some places might have 'No U-turn' signs, so stay alert. My advice is, no matter where you are, slow down and check before making a U-turn, especially paying attention to pedestrian signals. Make sure everything around you is safe before proceeding. After all, driving safety comes first—don’t risk it just to save a few seconds.
