When a motor vehicle is making a U-turn, turning, or descending a steep slope, the maximum driving speed shall not exceed 30 kilometers per hour. Conditions under which U-turns are permitted are as follows: Presence of U-turn traffic lights or signs: At an intersection with a U-turn traffic light, a U-turn can be made when the U-turn indicator light is green; if there is a U-turn sign at the intersection or a U-turn indicator marking on the lane, a U-turn can be made while ensuring the safety of oneself and others. No U-turn sign but left turns are allowed (no prohibition of U-turn signs or markings): Vehicles can make a U-turn at intersections where left turns are permitted and no prohibition of U-turn signs or markings are present. It is important to note that vehicles must proceed according to the left-turn lane traffic light signal without affecting the normal driving of other vehicles. 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-going light is green and wait until the left-turn light turns green to make the U-turn. U-turns are allowed at dashed lines: Whether it is a white dashed line or a yellow dashed line, U-turns are permitted. If it is a double yellow line with one solid and one dashed, check whether your side is the dashed line. If it is the dashed line, a U-turn can be made safely; if it is the solid line, U-turns are not allowed. If encountering a double yellow line with one solid and one dashed at an intersection, you can make a U-turn on the dashed line side, but you must not cross the stop line ahead. U-turns are allowed at yellow grid lines: Parking is prohibited in yellow grid line areas, but as long as there is no central isolation barrier, you can make a U-turn here after yielding to normally passing vehicles. U-turns are allowed on the side with dashed lines next to green belts: When the front of the green belt is a dashed line, vehicles on that side can make a U-turn from there. When the front of the green belt is a solid line, vehicles must follow the traffic light signal, cross the zebra crossing before making a U-turn, and are prohibited from crossing the solid line or zebra crossing to make a U-turn. Precautions for making U-turns: When making a U-turn, the left turn signal should be activated in advance, the maximum driving speed shall not exceed 30 kilometers per hour, and it must not hinder other vehicles and pedestrians driving normally.

During my driving lessons at the driving school, the instructor repeatedly emphasized the importance of maintaining a steady speed when making U-turns. Traffic regulations stipulate a maximum speed of 30 km/h, but I usually keep it under 20 km/h in practice. Especially at intersections with blind spots or during rainy days when tire grip decreases, going slightly faster can easily lead to loss of control. Once, while making a U-turn at the entrance of my neighborhood, a skateboarder suddenly darted out from the side. Fortunately, I was only going about 15 km/h at the time and managed to stop with a quick brake. Now, I’ve developed a habit: before making a U-turn, I check the rearview mirror, turn the steering wheel fully while lightly pressing the brake, as if carefully turning around with a full bowl of soup to avoid spilling. Maintaining good speed control not only reduces tire wear, saving money, but also ensures safety.

We veteran long-haul drivers all have this experience: the slower and steadier you make a U-turn, the better. While regulations set the upper limit at 30 km/h, the truly safe operating range is actually between 10-20 km/h. Last week when making a U-turn on a provincial highway construction zone with gravel-covered road surface, even at 12 km/h I could feel the rear wheels slipping. The key is to dynamically adjust based on road conditions: on six-lane divided highways you can go slightly faster, but must signal 200 meters in advance; in narrow alleys it's best to reduce to walking speed while gently tapping the accelerator. Long-bodied SUVs require even slower speeds than sedans, otherwise the rear end can easily scrape against traffic barriers. The most dangerous are novice drivers who accelerate during U-turns - I've seen too many side-swipe accidents caused this way.

After ten years in auto repair, I've seen too many failures caused by turning too quickly. Issues like deformed steering tie rods, uneven tire wear, and suspension noises mostly occur from jerking the wheel sharply at speeds over 30 km/h. I always advise drivers to keep U-turn speeds below 15 km/h, making smooth and steady turns like a park boat changing direction. On icy roads or steep slopes, reduce speed further to under 10 km/h while keeping the steering wheel rotation within half a turn. Remember, never accelerate before the car is fully straightened out – this small detail can save thousands in repair costs.
