Making a U-turn on a white dashed line is allowed and will not result in points deduction, provided there are no signs prohibiting U-turns or left turns, or separate U-turn signal lights. Vehicles can make a U-turn as long as it does not interfere with normal traffic flow and safety is ensured. Permissible situations for U-turns: Intersections with U-turn signs: If there is a clear U-turn sign at the intersection, a U-turn is allowed. If there is a U-turn signal light, follow its instructions. In the absence of a signal light, make the U-turn based on the specific situation, ensuring it does not obstruct other vehicles or pedestrians. Intersections without explicit prohibitions: If there are no signs explicitly prohibiting U-turns or left turns, a U-turn is allowed. "No explicit prohibition" means the absence of signs like "No U-turn," "No left turn," or solid center lines, in which case you can safely make a U-turn. Yellow grid lines also allow U-turns: 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—these zones are effectively "U-turn allowed" areas. Intersections with U-turn signal lights: This is straightforward—if there is a U-turn signal light, follow it. Only proceed with the U-turn when the light is green. When "No left turn" and "U-turn allowed" signs coexist: U-turns are permitted, but left turns are prohibited. Note that "No U-turn" is not the same as "No left turn." Points to note when making a U-turn: Observe road markings: If the line is solid, U-turns are strictly prohibited under any circumstances. Continue driving until you find a suitable spot. If there is a "No left turn" sign ahead, even if "No U-turn" is not mentioned, U-turns are not allowed at that intersection because U-turns inherently involve a left turn movement. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to oncoming traffic when making a U-turn. Proceed only if it does not disrupt the flow of straight-moving vehicles; otherwise, you will bear full responsibility for any accidents. Near intersection stop lines, lanes often have guiding arrows indicating permitted movements. Not all leftmost lanes have left-turn arrows—if a lane has a straight arrow, U-turns are prohibited even without explicit "No U-turn" signs. Making a U-turn on a crosswalk is also a traffic violation.

I remember when I first started driving, I was quite confused about traffic signs and always wondered if making a U-turn over white dashed lines would result in penalty points. According to traffic regulations, white dashed lines generally allow you to cross lanes for a U-turn, as long as you ensure safety and don’t violate specific rules, such as no 'No U-turn' signs or traffic light restrictions. Usually, you won’t get penalized. However, if your U-turn causes an accident or blocks other vehicles, the police might penalize you with points and fines. Once, I made a smooth U-turn over dashed lines in the suburbs without any issues. But a friend of mine got 3 penalty points for doing the same in a busy downtown area because he didn’t notice a 'No U-turn' sign at the intersection. So, the key is to assess the actual situation, develop the habit of checking signs and safety conditions to avoid penalties.

Last year, I got penalized for making a U-turn near the highway, which felt quite unfair. It was at a place with white dashed lines, and I thought U-turns were allowed there. Unexpectedly, there was a temporary no-U-turn sign, and due to heavy traffic without slowing down, I ended up encountering a patrol car. They issued me a ticket, deducting 2 points and fining me 200 RMB. From that lesson, I learned one thing: white dashed lines do permit U-turns, but only safely when no other restrictions apply. If you make a U-turn at an intersection or under a 'No Left Turn/U-turn' sign, even if it's a dashed line, you're taking a risk. Always observe your surroundings carefully while driving, don’t rush like I did back then—safety first can help avoid penalties.

After traveling to several cities, I found that the rules for U-turns at white dashed lines aren't always the same. For example, in my hometown small town, no one cares about U-turns at dashed lines; but in big cities like downtown Shanghai, there are sometimes special regulations restricting U-turns, with police keeping a closer eye. Generally, white dashed lines are marked for lanes allowing crossing actions, including U-turns, but local traffic regulations may specify additional requirements. For instance, in densely populated areas of Beijing, Shanghai, or Guangzhou, it's easy to get points deducted for unsafe behavior. I recommend that new drivers learn more about local traffic characteristics, check before going out or ask local friends, rather than just relying on seeing dashed lines to drive with confidence.

Many people mistakenly believe that white dashed lines are safe zones for free U-turns, but this is completely wrong. I've experienced and heard many cases where making a U-turn over white dashed lines without caution, such as near pedestrian crossings or in blind spots at intersections, carries a high risk of penalty points. The rule essentially allows you to temporarily cross the line, but you must ensure there are no potential hazards. If you fail to signal or drive too fast during a U-turn, the police will issue a fine. So don't assume 'dashed lines mean green light'—study the traffic manual more and develop safe driving habits as the golden rule.

Based on my driving experience, the key to avoiding demerit points when making a U-turn over white dashed lines is prevention. Before making a U-turn, always check for no-U-turn signs, traffic signal restrictions, or heavy pedestrian and vehicle flow in the vicinity; proceed slowly only after confirming safety. For example, I often make U-turns smoothly on suburban roads, but in urban areas, I opt for designated U-turn zones for added . Additionally, regularly reviewing traffic rules helps prevent minor mistakes. While demerit points are a small matter, safety is paramount. Developing this awareness can protect you from penalties.
