Making a U-turn over a single solid line is a traffic violation. According to Article 90 of the Road Traffic Safety Law, violators who disobey prohibited road markings will be fined 200 yuan and receive 3 penalty points. Generally, on long roads, white solid lines are often present in the middle sections or before intersections. If the lines are yellow dashed or white dashed, U-turns are permitted. However, U-turns are strictly prohibited over any solid lines. Permissible U-turn situations: U-turn allowed at intersections with U-turn signs: If there is a clear U-turn sign at an intersection, a U-turn is permitted. If there is a U-turn traffic light, follow its instructions. If there is no traffic light, make the U-turn based on the specific situation, ensuring it does not obstruct other vehicles or pedestrians. U-turn allowed at intersections without explicit no-U-turn or no-left-turn signs: If there are no signs explicitly prohibiting U-turns, they are allowed. "No explicit prohibition" means the intersection lacks signs like "No U-turn," "No left turn," or solid center lines, allowing U-turns with confidence. U-turns allowed over yellow grid lines: Yellow grid lines are no-parking zones, typically marked at intersections prone to congestion due to temporary stops, entrances of important facilities, or other designated areas. Stopping on these lines (including waiting at traffic lights) is a violation. Although parking is prohibited in yellow grid zones, U-turns are permitted as long as there are no central barriers, effectively making them "U-turn allowed" zones. When "No left turn" and "U-turn allowed" signs appear together: U-turns are permitted, but left turns are prohibited. Note that "No U-turn" is not the same as "No left turn." Precautions when making U-turns at intersections: Observe road markings—U-turns are never allowed over solid lines under any circumstances. Continue driving to find a suitable spot. If a "No left turn" sign is present, U-turns are also prohibited at that intersection, even if "No U-turn" is not mentioned, as U-turns inherently involve left-turning movements. U-turns must be made from the innermost left-turn lane. If in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to straight-moving vehicles before making a U-turn. Failure to do so may result in full liability for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow—some may have straight arrows. Even without explicit "No U-turn" signs, U-turns are prohibited in such lanes. U-turns must not be made on pedestrian crosswalks, as this is also a violation.

I remember driving a taxi for several years and often saw people getting caught making U-turns over a single solid line. The traffic police said this violates the rule of disobeying prohibitory traffic markings. Once caught by surveillance cameras or on-site enforcement, it results in a 200-yuan fine and 3 demerit points. It might not sound like much, but it adds up and becomes quite troublesome. I once saw a guy who had to retake his driving test because he accumulated too many demerit points—it was time-consuming and exhausting. More importantly, making a U-turn over a single solid line is extremely dangerous, as it can easily block the cars behind you. If it leads to a rear-end collision, the consequences would be far worse. So now, I drive very carefully and always remind myself to follow the rules, taking a few extra steps to make a safe U-turn at an intersection. In fact, the rules are there to protect everyone—don’t take shortcuts and risks just to save time. Navigation apps also remind you not to make illegal U-turns. Just make it a habit, and you’ll save yourself from regret later.

When I first bought my car, I was really curious about traffic rules. I looked it up online and learned that you can't just make a U-turn over a solid single line. I asked my friends, and they all said the most common penalty is a 200-yuan fine and 3 demerit points, and you might even get a ticket. During my novice period, I almost violated the rule, but luckily my car navigation warned me to avoid the solid single line. After that incident, I started paying more attention to roadside signs. Solid single lines are common at intersections or highway entrances, and making a U-turn there can disrupt traffic order and attract police patrols. The fine isn't small, but I'm more afraid of the demerit points affecting my driving record. Now, I plan my route in advance and use mobile maps to check road conditions to avoid such mistakes. New drivers should study traffic rule apps more to develop good habits and avoid unnecessary fines.

I always prioritize safety when driving, and making a U-turn over a single solid line is absolutely a big no-no. The rules clearly prohibit such violations, and the penalty is usually a 200-yuan fine plus 3 demerit points, but the harm goes beyond that. It disrupts the flow of traffic, leading to sudden braking or collisions from vehicles behind. This behavior is often seen in congested areas where traffic police strictly monitor it. I recommend everyone obey the road signs and opt for designated U-turn zones instead. This can reduce the risk of accidents and save both money and stress. Safety is far more important than saving time.
