Normally, you need to wait for the left-turn signal to turn green to ensure safety and complete the U-turn without affecting other vehicles. However, there are also some intersections where you can make a U-turn directly without waiting for the traffic light. Cases where you don't need to wait for the traffic light: If there is a sign before the traffic light intersection indicating that U-turns are not controlled by the traffic light, you can make a U-turn directly. If there is a dashed U-turn line before the traffic light intersection and the dashed line does not exceed the stop line, you can make a U-turn directly without being controlled by the traffic light. If there is a dedicated U-turn channel set up before the stop line by the median strip or guardrail at the intersection, you can make a U-turn directly. Cases where U-turns are prohibited: Intersections where left turns are prohibited. If there is a no-left-turn sign at the intersection, even if there is no no-U-turn sign, U-turns are also prohibited at that intersection. U-turns are prohibited in crosswalk areas. Crosswalks are for pedestrian passage, and vehicles are prohibited from making U-turns; even if U-turns are allowed, they should be performed away from the crosswalk. If there are two left-turn lanes, the one closer to the middle of the road prohibits U-turns. If there are no signs or U-turn lines, U-turns can only be made in the innermost left-turn lane. Intersections with no-U-turn signs prohibit U-turns. If the leftmost lane is a straight lane, U-turns are prohibited. If the centerline of the road is solid, U-turns are prohibited. Areas where U-turns are not allowed: railway crossings, crosswalks, bridges, sharp curves, steep slopes, and tunnels.

I've been driving on the road for many years, and whether you need to wait for a red light to make a U-turn actually depends on a lot of variables. It mainly comes down to the specific intersection design and traffic signal rules. If there are flashing traffic lights at a crossroads, you generally need to wait for the green light to make a U-turn; otherwise, it might count as running a red light, risking being caught on camera for a fine or causing a collision. In some places, like under overpasses or certain one-way streets, there might be signs saying 'U-turn not restricted by signals,' meaning you can go even on a red light—but you must confirm the road signs clearly. I’ve had a few close calls myself when I rushed a U-turn without waiting for the red light and nearly hit oncoming electric scooters—lessons learned the hard way. So while driving, I’ve developed a habit of slowing down first to observe: first, check the traffic light status; second, see if there are any 'no U-turn' markings or signs at the intersection; and third, watch out for pedestrian safety—better to wait a few extra seconds than act recklessly. This approach has helped me avoid trouble, because safety always comes first.

When I first got my driver's license, I was quite confused about the rules for making U-turns, but now I've figured out some of the basics. In most cases, you do need to wait for a green light to make a U-turn, especially at traffic light intersections on urban main roads. The U-turn maneuver must be performed when the light is green to ensure safety; otherwise, running a red light could result in being caught by traffic cameras and fined by the police. However, exceptions exist in places with dedicated U-turn lanes, such as certain highway exits or roundabouts, where you can make a U-turn even during a red light—but only if the road signs explicitly state 'U-turn permitted.' I always pay attention to this detail when driving, as misreading the traffic signals could lead to chaos or fines. During my novice phase, I often simulated this scenario: patiently waiting for a green light at a red-light intersection before making a smooth turn, while also checking the blind spots for pedestrians or motorcycles. Over time, this became second nature, significantly reducing driving risks.

In this line of work where you drive for long hours, the rule for making U-turns boils down to being flexible with traffic signals. If a red light is flashing, you must wait for the green light before making a U-turn—don’t rush it, or accidents can happen. Typically, intersections require vehicles to wait for the signal, especially in high-traffic areas, to avoid collision risks. However, if the intersection has special designs, like a dedicated U-turn channel or no interfering signals, you can proceed even on red. I advise drivers to develop the habit of anticipation: slow down, observe signal changes, and then act. One careless illegal U-turn could mean points deducted and fines—not worth it. Safety should always be the fundamental priority in driving.
