Do U-turns at intersections require observing traffic lights?

[McMax]

If the gap is marked with dashed lines, the U-turn is not affected by traffic signals and does not require crossing the pedestrian crossing. In such cases, you can make a U-turn directly, provided it does not interfere with other normally moving vehicles and ensures your own safety. However, if the gap is marked with solid lines, the U-turn must cross the pedestrian crossing and is subject to traffic signal control. When making a U-turn that requires crossing the pedestrian crossing, yielding to pedestrians is necessary: If pedestrians are walking on the right side of the crosswalk and have not reached the centerline of the road, vehicles on the left side should slow down and proceed only after ensuring safety. If pedestrians are waiting outside the boundary line between motorized and non-motorized lanes and have not entered the roadway, vehicles should slow down and proceed only after ensuring safety. If pedestrians cross the boundary line between motorized and non-motorized lanes, vehicles must stop; failing to do so is a violation and subject to penalties. If pedestrians enter the motorized lane from the crosswalk, vehicles must slow down and proceed only after ensuring safety. Failing to stop is a violation and subject to penalties. If pedestrians are waiting at the centerline of the road without entering the motorized lane, vehicles must stop; otherwise, it is a violation and subject to penalties. If pedestrians cross the centerline into the motorized lane, vehicles must stop; otherwise, it is a violation and subject to penalties. If the road is divided by a green belt and pedestrians are waiting in the middle area, vehicles must slow down and proceed only after ensuring safety. Scenarios where U-turns are allowed: If there is a U-turn sign at the intersection, you can make a U-turn. If there is a U-turn traffic light, follow its instructions. If there is no traffic light, make the U-turn only if it does not interfere with other vehicles or pedestrians. If there is no explicit prohibition of U-turns or left turns at the intersection, U-turns are allowed. This means if there are no "No U-turn" or "No Left Turn" signs and the centerline is not solid, you can safely make a U-turn. U-turns are also allowed in yellow grid zones. While stopping in these zones is prohibited (including waiting for traffic lights), U-turns are permitted unless there is a central barrier. If there is a U-turn traffic light, follow its instructions—only proceed on green. If "No Left Turn" and "U-turn Allowed" signs appear together, U-turns are permitted but left turns are not. Note that "No U-turn" does not mean "No Left Turn." Precautions when making U-turns at intersections: Check the road markings. If they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable spot. If there is a "No Left Turn" sign, U-turns are also prohibited, even if "No U-turn" is not explicitly stated, as U-turns involve left turns. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not allowed at that intersection. Always yield to oncoming straight-moving vehicles before making a U-turn. Failing to do so makes you fully liable for any accidents. Near the intersection stop line, lanes usually have guiding arrows. Not all leftmost lanes have left-turn arrows; some may have straight arrows. Even without explicit "No U-turn" signs, U-turns are not allowed in such lanes.

Whether to observe traffic lights when making a U-turn depends on the situation. At intersections with dedicated U-turn signals, you must strictly wait for the green light—I've seen several drivers get caught by cameras for rushing through. Most intersections don't have this specific signal, allowing U-turns whenever the left-turn light is green. Two key points: First, wait behind the stop line until the light turns green—crossing the line counts as a violation. Second, don’t disrupt oncoming straight traffic; I’ve often seen new drivers force sudden brakes by cutting off cars. For gaps in median barriers, U-turns can be made without checking lights, but prioritize safety by ensuring no approaching vehicles. Another pitfall is U-turning before crosswalks—wait until all pedestrians have crossed. Last time, I nearly hit a delivery rider running a red light.

Simply put, just follow the left-turn signal. However, there are a few exceptions to note: if you see a gap in the double yellow line, you can make a U-turn without worrying about the traffic light; if you encounter a solid red light but there's a clearly marked U-turn lane at the intersection, you can proceed without waiting for green (but must yield to pedestrians and through traffic). The most dangerous scenario is when there's a 'No U-turn' sign painted in the middle of the road—no matter how urgent, don't take the risk. My colleague got a ticket and scraped his side mirror last week for forcing a U-turn to save time. A reminder to new drivers: don't blindly trust navigation apps, as some intersections may have newly installed no-U-turn signs that haven't been updated in the system. Be extra cautious when making U-turns in the rain—avoid turning the steering wheel too sharply to prevent losing control.

After driving for ten years, I've summarized the ironclad rules for U-turns: Always yield to pedestrians at crosswalks; always check traffic lights at stop lines. No matter the situation, if there's a stop line, you must wait for the green light before crossing it to make a U-turn. Some complex intersections have dual-layer traffic lights, with the upper layer controlling straight traffic and the lower layer controlling U-turns—read the signs carefully before moving. The most annoying thing is when someone makes a U-turn by creeping over the stop line, almost causing a rear-end collision and definitely getting caught on camera for demerit points. A reminder for friends driving at night: at unlit intersections, sweep your headlights left and right to check carefully before making a U-turn—last week, I almost hit an unlit tricycle by the roadside.

Check for these four signs to decide: U-turn dedicated light > left-turn light > no U-turn sign > uncontrolled gap. Traffic lights with arrows are the easiest - stop at red, go at green. At intersections with only circular lights, remember this rule: 'U-turn allowed on green, don't cross the line on red.' Key points about common mistake scenarios: When the left-turn light is green but the intersection is congested, don't force your way to the middle to wait for a U-turn - wait properly behind the stop line. I've seen new drivers stuck in the middle blocking traffic from all directions and getting lectured by traffic police for half an hour. In rainy weather, rear wheels tend to slip during U-turns, so steer back to center slowly.

Every licensed driver knows U-turns require watching traffic lights, but there's nuance in practice. At intersections with stop lines, you must obey the signal—even at 3 AM with no traffic (I got flashed by a mobile camera doing a 2 AM red-light U-turn). Watch for special road designs: yellow grid zones permit direct U-turns, while green arrow markings dictate mandatory turning directions. A hard lesson: last year in an unfamiliar city, I missed secondary traffic lights behind the crosswalk, crossing the line as it turned red—resulting in a red-light violation. Now I always count all signal groups before turning.
