At intersections with U-turn traffic lights and lanes marked with U-turn signs, U-turns are permitted. In the absence of a U-turn signal or a no U-turn sign, vehicles may perform a U-turn provided it does not interfere with other traffic and is done safely. Areas marked with yellow grid lines strictly prohibit parking. When the traffic light ahead is red, vehicles behind should avoid stopping in these zones. While crosswalk areas typically lack no U-turn signs, they are strictly off-limits for U-turns as they are designated pedestrian zones. Intersections marked with no left-turn signs prohibit both left turns and U-turns.

When I first learned to drive, the instructor repeatedly emphasized the importance of checking traffic lights when making a U-turn. Never attempt a U-turn when the red light is on—not only is it a traffic violation, but it could also lead to collisions with pedestrians or oncoming vehicles. Even when the light turns green, proceed with caution: slow down first and observe your surroundings—check for pedestrians suddenly crossing from the side or congestion in the opposite lane—and only turn when it's safe. I still remember one time at an urban intersection, I was about to make a U-turn on a green light but overlooked a delivery rider in the bike lane—it was a close call. Since then, I've developed the habit of waiting an extra two seconds. Some intersections have dedicated U-turn signals, so pay attention to the arrow indicators; if there's no arrow, follow the standard traffic light rules. New drivers often get impatient, but a little patience is always better than an accident.

From the perspective of signal comprehension, the operation of a U-turn traffic light is quite intuitive. When the green light is on, you can make a U-turn, provided the lane permits it and there are no obstructions. The yellow warning light indicates an impending change to red, at which point it's advisable to stop and wait rather than accelerate through. A red light completely prohibits U-turns, requiring you to wait for the green light. Additionally, pay attention to auxiliary signs, such as "U-turn permitted" notices beside traffic lights at some intersections or directional arrow signals. In the absence of clear signage, adhere to general traffic rules—yield to vehicles going straight and ensure your U-turn doesn't interfere with them. Also, remember your position relative to the stop line; make sure to stop within the line to avoid obstructing others' views and potentially causing rear-end collisions due to misleading signals.

I've been driving for several years, and making U-turns mainly depends on the traffic light colors. When the green light is on, I proceed to make a slow U-turn, but always glance at the rearview mirror and check the rear situation to prevent any sudden motorcycles from appearing. At a red light, I definitely stop and wait obediently. There aren't any complicated rules—just simply follow the signals and don't act on your own. Once, a friend ran a red light to make a U-turn and got fined 200 yuan plus penalty points—a big lesson. So now I've developed a habit: slow down when approaching an intersection, clearly check the light color before moving, saving both trouble and money.
