Making a U-turn over a single yellow line on the road is not allowed. According to the relevant regulations of the "Road Traffic Safety Law of the People's Republic of China," whether it is a single yellow line or a double yellow line, as long as it is a solid line, crossing is strictly prohibited. Here is an introduction to single yellow lines: There are two types of single yellow lines: Single yellow lines are divided into dashed lines and solid lines. As long as a single yellow line is solid, crossing is strictly prohibited, such as for overtaking, turning, or making a U-turn. When driving, if there are no special circumstances, you should not cross the line; if the single yellow line is dashed, you can overtake or make a U-turn when it is safe to do so. Introduction to single yellow lines: Single yellow lines serve as center dividing lines to separate traffic directions. A yellow dashed line allows temporary crossing for lane changes when driving; a solid line should be treated like a wall and must not be crossed. Roads with four or more lanes in both directions are marked with double yellow lines, while roads with fewer lanes use single yellow lines. Crossing solid double yellow lines to make a U-turn constitutes a traffic violation against prohibited markings, and in the event of a traffic accident, the driver will bear primary responsibility.

After driving for so many years, I've encountered quite a few questions about U-turns at yellow lines. The solid yellow line in the middle of the road usually indicates a no-crossing zone, meaning you shouldn't casually cross it to overtake or make a U-turn, otherwise you could easily get a traffic violation or cause an accident. Generally speaking, making U-turns near solid yellow lines is against the rules, such as on urban arterial roads or highways; it's only potentially allowed at dashed yellow lines where there are no no-U-turn signs nearby. However, rules vary by location, so it's best to check local traffic regulations or perform the maneuver at intersections with clear left-turn indicators. Safety comes first—don't take risks just to save time. If you really need to make a U-turn, find a proper intersection or designated area to avoid trouble. Developing good habits is crucial. I always pay attention to roadside signs and traffic signals when driving.

When I first learned to drive, I was always confused about whether I could make a U-turn over a yellow line. Later, I gradually understood. The yellow line is mainly the centerline marking of the road. If it's a solid line, absolutely don't cross it—making a U-turn directly across it could easily get you a ticket from the police or cause a rear-end collision. A dashed line sometimes allows crossing depending on the situation, but you must ensure it's safe with no oncoming traffic. The key to making a U-turn is to observe the on-site signs and road conditions, such as whether there's a 'No U-turn' sign or traffic light control. If you're unsure, it's better to take a detour and find a safer spot to turn around rather than attempting it in an unclear area. Driving isn't just about rules—it's also about your safety and others', which is why my instructor emphasized this repeatedly during practice. Here's a handy tip: use navigation apps to help identify spots where U-turns are allowed.

From a road safety perspective, making U-turns over yellow lines carries high risks. Solid lines explicitly prohibit crossing to prevent accidents, including U-turns; while dashed lines may permit it under certain conditions, hazards like blind spots or oncoming traffic still exist. Always perform U-turns in strict compliance with traffic signals—ignoring yellow line rules easily leads to collisions. Remember the core principle: let road markings guide your actions. If yellow lines are clearly visible or combined with other prohibition signs, never attempt it. Driving requires patience and judgment—cultivating good habits ensures overall smooth traffic flow. This is crucial for my daily driving; I constantly remind myself not to take shortcuts.

As a car enthusiast, I must mention the original intent of road design when talking about U-turns over yellow lines. The solid yellow line is a standard traffic engineering divider, meaning you cannot cross it arbitrarily - whether for overtaking or U-turns, it's considered a violation unless at a dashed line section without prohibitive signs. In practical operation, I recommend drivers prioritize intersection markings or traffic light instructions; on yellow lines without explicit U-turn permission, maintaining straight driving is safer. The key to avoiding accidents lies in familiarizing yourself with local regulations, which may differ between urban and suburban areas. Through years of driving, I've found that adhering to these details makes vehicles more durable and safer.
