Generally, you cannot make a U-turn when encountering a red light while turning left, but if there is a dashed line before the stop line, you can make a U-turn at the dashed line. Below is relevant information about making a U-turn during a red light: General Situation: When there is no 'No U-Turn' sign at the intersection, the left-turn lane allows a U-turn during a green light but prohibits it during a red light. No U-Turn Sign: When a 'No U-Turn' sign is present at the intersection, the left-turn lane does not serve as a U-turn lane, and U-turns are not allowed in the left-turn lane, regardless of the traffic signal. Dashed Line Before Stop Line: If there is a dashed line in the left-turn lane or a dedicated U-turn lane, you must complete the U-turn within the dashed line or in the U-turn lane, regardless of the traffic signal. Solid Line Before Stop Line: If there is a solid line before the stop line, you can only make a U-turn after crossing the stop line. If there is a U-turn traffic signal, follow its instructions. If there is no U-turn signal, follow the left-turn signal to make a U-turn.

When making a left U-turn and encountering a red light, you generally cannot turn around at will. Traffic regulations typically require all vehicles to stop and wait at a red light, including U-turns, unless the intersection has a dedicated U-turn signal or a green arrow indicating it's permitted. As someone who drives frequently, I have plenty of city driving experience. I remember once at a busy intersection, I attempted a U-turn and ended up getting a ticket from a traffic camera—regretting not checking the signs. Safety is the bottom line; even if there are no other vehicles, you must follow the rules to avoid accidents or fines. I recommend everyone develop the habit of first checking for any 'No U-turn' signs at intersections. It's best to wait for a green light or find an area where U-turns are allowed—this way, you can drive with peace of mind and avoid trouble.

I think making a U-turn at a red light is very unsafe because it may obstruct the view of oncoming lanes or cause chain collisions. For example, on the roads in our residential area, motorcycles or pedestrians often appear suddenly, and it would be a big trouble if an accident happens. Drivers should prioritize pedestrians and other vehicles, strictly wait according to the traffic lights, rather than taking risks. I have also consulted some urban traffic guidelines, and most places emphasize that U-turns at red lights are illegal and will result in fines. To be on the safe side, if you really need to make a U-turn, choose a quiet intersection in advance, observe the signage positions, and ensure there is no 'No U-turn' sign before proceeding. Otherwise, it's better to take a detour for peace of mind.

I also asked my driving instructor this question, and he said unless there's a clear green light indicating a U-turn, don't move during a red light. After driving for over a decade, I've noticed many beginners ignore this rule and often get into accidents. Legally, it's considered running a red light with high risks, and the fines or points deduction aren't worth it. My own experience tells me it's better to wait a few minutes for the green light or find another place to make a U-turn.
