Is it allowed to make a U-turn when the red light is on?

[LeAaron]

It is allowed to make a U-turn when the red light is on, but whether a U-turn is permitted depends on the intersection signage. Here are the regulations regarding U-turns at red lights: 1. No U-turns on crosswalks: If the intersection allows U-turns but has crosswalks, U-turns cannot be made on the crosswalk. If there is a left-turn lane, you can make a U-turn along the guided lane. If there is no left-turn guidance marking, you should first cross the crosswalk before making a U-turn. 2. Yellow grid zones: The yellow grid areas on the road primarily serve as no-parking indicators. If you drive into a yellow grid zone and there is no central divider, U-turns are permitted within the yellow grid area. 3. Solid yellow lines prohibit U-turns: If the center line is solid, whether single or double yellow lines, U-turns are prohibited. If there is one dashed yellow line and one solid yellow line, and the dashed line is closer to your vehicle, U-turns are allowed. If the solid line is closer to your vehicle, U-turns are prohibited.
