Circular red lights do not permit U-turns. Reasons prohibiting U-turns at circular red lights: At intersections without prohibited U-turn signs, drivers may execute U-turns during green light phases, provided they do not impede the normal flow of other vehicles or pedestrians. According to Article 49 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China, motor vehicles are prohibited from making U-turns at locations with no U-turn or no left turn signs/markings, as well as at railway crossings, crosswalks, bridges, sharp curves, steep slopes, tunnels, or other potentially hazardous road sections. Permissible U-turn conditions: Motor vehicles may make U-turns at locations without prohibited U-turn or no left turn signs/markings, but must not obstruct other properly moving vehicles or pedestrians. At intersections without dedicated non-motor vehicle or pedestrian traffic signals, cyclists and pedestrians should follow the indications of motor vehicle traffic signals.

















After driving for so many years, I've learned that making a U-turn at a circular traffic signal actually depends on the signal color and the intersection conditions. When the light is green, U-turns are generally allowed as long as the intersection is wide enough and there are no signs or markings prohibiting U-turns. However, making a U-turn on a red light is absolutely not allowed—it's equivalent to a left turn and constitutes illegal operation, which can easily lead to accidents. I always check for safety before proceeding, such as looking for pedestrians crossing or other vehicles cutting in. My road experience tells me that on urban main roads or near schools, U-turns carry higher risks, so it's safer to take a detour instead. Safe driving is no trivial matter—accidents often stem from carelessness. That's why I make it a habit to wait a few extra seconds to confirm the road conditions before executing any maneuver.

As a parent who often drives my kids around, safety always comes first. When the circular traffic light turns green, theoretically, you can make a U-turn, but I always check first for any 'No U-turn' signs or solid yellow lines at the intersection. Under no circumstances should you attempt it during a red light—that's far too dangerous. My kids often complain about being in a hurry on the road, but I insist on taking extra time to observe: waiting for lighter traffic and ensuring pedestrians have cleared the area before proceeding. Once, I tried making a U-turn at a slippery, rain-soaked intersection and nearly lost control of the car—now I'm even more cautious. Remember, the rules aren't just written in books; in real driving, even a small oversight can put your entire family at risk. Develop good habits, avoid sharp turns or sudden braking at high speeds, and protect both yourself and others.

I just got my driver's license a few months ago, and this issue has been bothering me too. When it comes to making a U-turn under a circular traffic light, my instructor taught me to only consider it when the light is green—don't even think about it when it's red. Under a green light, you have to check the signs—if there's a red cross or a line indicating no U-turns, don't attempt it. In actual practice, as a new driver, I tend to panic easily, always worried about making a wrong judgment that could lead to an accident. So, I first practiced a few times in open areas before trying it in real traffic. Although the rules allow U-turns on green, in busy urban areas or during rainy or foggy weather, I suggest new drivers avoid taking the risk and instead take a detour for safety. After all, points and fines are minor compared to personal safety, which is what truly matters.

I often drive across the country and notice varying traffic rules. In big cities, circular green lights usually allow U-turns, but some sections prohibit them; rural areas might be more lenient, relying on driver awareness especially with aging signals. For instance, in some foreign countries, U-turns are freely permitted at green lights, but Chinese traffic regulations emphasize doing so only when no prohibitory signs exist. U-turns are universally banned at red lights. Regional differences are significant, so checking local traffic rule apps or consulting experienced local friends before long trips is practical. Adapting to different environments is an essential skill for drivers to avoid misunderstandings or accidents due to differing customs.

As a driving enthusiast, I'd like to share some practical tips: When the circular traffic light turns green, U-turns are permitted, but choose wide intersections for this maneuver and avoid attempting it in narrow lanes. Never attempt a U-turn at a red light—it's both illegal and dangerous. The technique is: Don't rush to turn when the light turns green; first check for side traffic and pedestrian flow. If possible, slow down gradually to ensure a safe distance. In daily driving, always pay attention to whether there are additional signs near the intersection traffic lights—those small signs are often the deciding factor. Carry a traffic rulebook or use your to remind yourself, and develop the habit of safe driving to save both worry and effort.
