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.

After driving for so many years, I've encountered quite a few confusions about U-turns at round red traffic lights. The key is actually to check whether there's a no U-turn sign at the intersection. If there's no specific prohibition, you can make a U-turn directly regardless of whether the light is red or green. However, it's crucial to pay special attention that the U-turn maneuver must be completed before the stop line, without crossing the pedestrian crossing, and ensuring it doesn't affect vehicles going straight. Last time I made a U-turn in the city, I specifically observed the left-turn guiding arrows on the ground—following that direction was very reliable. What I fear most is encountering intersections with safety islands; in such cases, I'd rather wait for the green light. When driving, safety is the top priority. If you're unsure, waiting for a green light isn't a big deal—it's just a few dozen seconds.

I remember discussing this with friends last time, and they all said making U-turns at traffic lights is complicated. Actually, it's not that difficult—it mainly depends on the specific intersection setup. Every time, I first look up for signs to see if there's a red no-U-turn symbol. If there isn't, you can turn around whether the light is red or green. But in practice, I've noticed many new drivers make the mistake of trying to U-turn in front of through traffic. So I always let through traffic pass first and make sure no one is coming from the opposite lane before turning the wheel. Another detail: if the U-turn requires crossing a pedestrian crossing, be sure to wait until pedestrians have completely crossed before moving.

When making a U-turn at a circular traffic light while driving, I usually handle it this way: First, check if there are any no U-turn signs at the intersection. If not, you can basically make a U-turn regardless of whether the light is red or green. But pay attention to two points: First, the maneuver must be completed before the stop line—don't cross it; second, never interfere with oncoming straight-moving vehicles. Once, at an intersection with a dedicated U-turn lane, I smoothly completed the U-turn in the far-left lane. In special situations, such as intersections with guardrails or dividers, it's safer to wait for the green light.

At the driving school, the instructor repeatedly emphasized the rules for U-turns at circular traffic lights. As long as there is no 'No U-turn' sign at the intersection, you can complete a U-turn even when the red light is on. However, practical operation requires attention to technique: avoid turning the steering wheel too sharply, making a smooth and wide turn is the safest; turn on the turn signal 200 meters in advance; and be especially vigilant of vehicles approaching diagonally from behind. The road markings at the intersection I frequent are very clear, with dotted guide lines in the left-turn area—just follow them and you won't go wrong. If you see a sign that says 'U-turn permitted on red,' that’s even more reassuring.

When dealing with U-turns at circular traffic lights, I first check the traffic signs. In the absence of prohibition signs, U-turns are permitted on both red and green lights. However, there are three ironclad rules: never interfere with pedestrians crossing the road; ensure there are no oncoming straight-moving vehicles approaching; and the U-turn trajectory must be completed within the stop line. Once at a downtown intersection, because a bus on the right blocked my view, I waited a few extra seconds to assess the road conditions before proceeding. If the intersection has multiple left-turn lanes, prioritize using the leftmost lane for the U-turn. Additionally, I remind myself to always use the turn signal to alert vehicles behind me.
