Making a U-turn over a solid line is a traffic violation. According to the Road Traffic Safety Law, violators will be fined 200 yuan and receive 3 penalty points. Generally, on long roads, solid white lines are usually present in the middle sections or before intersections. If the lines are yellow dashed or white dashed, U-turns are allowed. However, U-turns are strictly prohibited over any solid lines. Permissible situations for U-turns: Intersections with U-turn signs allow U-turns: If there is a clear U-turn sign at an intersection, U-turns are 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. Intersections without explicit no-U-turn or no-left-turn signs allow U-turns: If there is no explicit prohibition, U-turns are allowed. "No explicit prohibition" means the absence of "no-U-turn signs," "no-left-turn signs," or solid lines in the middle of the road. In such cases, U-turns are permitted. Yellow grid lines also allow U-turns: Yellow grid lines are no-parking zones, usually marked at intersections prone to congestion due to temporary parking, entrances of important facilities, or other necessary locations. Parking (including waiting at traffic lights) on these lines is a violation. Although parking is prohibited in yellow grid zones, U-turns are allowed as long as there are no central barriers. The presence of yellow grid lines without barriers is equivalent to "U-turns permitted." Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn traffic light, follow it. U-turns are only allowed when the light is green. When no-left-turn and U-turn-permitted signs coexist: U-turns are allowed, 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—if they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable location. If there is a "no left turn" sign, even if there is no explicit "no U-turn" sign, U-turns are not allowed at that intersection because U-turns inherently involve left-turning movements. 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 straight-moving vehicles before making a U-turn. Proceed only if it does not interfere with their normal flow; otherwise, you will bear full responsibility for any accidents. Near intersection stop lines, lanes usually have guiding arrows for vehicle direction. The leftmost lane does not always have a left-turn arrow. On some roads, if the arrow is for straight movement, U-turns are prohibited even if there are no explicit "no U-turn" signs. U-turns are not allowed on pedestrian crosswalks, as this is also a traffic violation.
