Is U-turn allowed at circular traffic lights?

[MacAiden]

U-turn is allowed at circular traffic lights. According to the "Regulations for the Implementation of the Road Traffic Safety Law": Motor vehicles can make U-turns at locations where there are no prohibitory signs or markings against U-turns or left turns, provided that they do not hinder the normal passage of other vehicles and pedestrians. Circumstances allowing U-turns: Presence of U-turn traffic lights or signs: U-turns are permitted when there are traffic lights allowing U-turns at the intersection. No U-turn signs but left turns allowed (no prohibitory U-turn signs): If making a U-turn at an intersection with a left-turn waiting area, you can first enter the left-turn waiting area when the straight-through light is green, and then make the U-turn when the left-turn light turns green. U-turns allowed at dashed lines: Whether it's a white dashed line or a yellow dashed line, U-turns are permitted. For double yellow lines with one solid and one dashed, check if your side is the dashed line; if so, a U-turn is allowed safely. If it's a solid line, U-turns are prohibited. At intersections with double yellow lines (one solid, one dashed), U-turns can be made on the dashed 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 green belts: When the front of the green belt is a dashed line, vehicles on that side can make U-turns from there. When the front of the green belt is a solid line, vehicles must follow traffic light instructions, cross the zebra crossing before making a U-turn, and must not cross the solid line or the zebra crossing for the U-turn. Precautions for U-turns: When making a U-turn, you should activate the left turn signal in advance, and the maximum speed should not exceed 30 kilometers per hour. Do not hinder the normal passage of other vehicles and pedestrians.
