Whether you can make a U-turn at a red light in a dedicated U-turn lane depends on the situation. If the U-turn does not cross the stop line of the lane and does not affect the normal driving of other vehicles, you can make a U-turn at a red light. However, if the U-turn requires crossing the stop line of the left-turn or U-turn lane, you must follow the traffic light instructions. Conditions under which U-turns are allowed: Presence of U-turn signals or signs: If there is a U-turn signal at the intersection, you can make a U-turn when the U-turn signal is green. If there is a U-turn sign at the intersection or a U-turn indicator on the lane, you can make a U-turn as long as you ensure the safety of yourself and others. No U-turn signs but left turns are allowed (no prohibition of U-turn signs): At intersections where left turns are allowed and there are no signs or markings prohibiting U-turns, you can make a U-turn. Note that vehicles must proceed according to the left-turn lane signal without affecting the normal driving of other vehicles. If you want to make a U-turn at an intersection with a left-turn waiting area, you can first enter the waiting area when the straight-ahead light is green and then make the U-turn when the left-turn light turns green. U-turns allowed at dashed lines: U-turns are allowed at both white and yellow dashed lines. For double yellow lines with one solid and one dashed, check whether your side is the dashed line. If it is, you can make a U-turn safely. If it is a solid line, U-turns are not allowed. At intersections with double yellow lines (one solid, one dashed), you can make a U-turn on the dashed line side, but you must not cross the stop line ahead. U-turns allowed at yellow grid lines: Parking is prohibited in yellow grid areas, but as long as there is no central barrier, you can make a U-turn here after yielding to normally moving vehicles. U-turns allowed on the dashed side of a green belt: When the front of the green belt is a dashed line, vehicles on that side can make a U-turn from there. When the front of the green belt is a solid line, vehicles must follow the traffic signal, cross the pedestrian crossing before making a U-turn, and are prohibited from crossing the solid line or pedestrian crossing to make a U-turn.
