Making a U-turn over solid lines is a traffic violation. According to Article 90 of the Road Traffic Safety Law, violators will be fined 200 yuan and receive 3 demerit points. Generally, on long roads, white solid lines are 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 U-turn situations: Intersections with U-turn signs: 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. In the absence of a traffic light, U-turns can be made based on the specific situation, provided they do not obstruct other vehicles or pedestrians. Intersections without explicit no-U-turn or no-left-turn signs: U-turns are allowed if there are no signs explicitly prohibiting them. "No explicit prohibition" means the absence of "no U-turn," "no left-turn" signs, or solid lines in the center of the road. In such cases, U-turns can be safely made. Yellow grid lines also permit U-turns: Yellow grid lines are no-parking zones marked at intersections prone to congestion due to temporary stops, entrances/exits of important facilities, and other necessary locations. Parking on these lines (including waiting at traffic lights) is prohibited. Although stopping is not allowed in yellow grid zones, U-turns are permitted as long as there are no central barriers. Yellow grid lines without barriers are equivalent to "U-turn permitted." Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn traffic light, proceed only when it is green. Simultaneous no-left-turn and U-turn permitted signs: 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 solid lines are present, U-turns are prohibited under any circumstances. Continue driving to find a suitable location. If a "no left-turn" sign is present, U-turns are also prohibited at that intersection, even if there is no explicit "no U-turn" sign, as U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. U-turns are not allowed from the second left-turn lane. Always yield to oncoming traffic when making a U-turn. Ensure the maneuver does not interfere with straight-moving vehicles, or you will bear full responsibility for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow. If a straight arrow is present, U-turns are prohibited even without explicit "no U-turn" signs. U-turns must not be made on pedestrian crosswalks, as this is also a traffic violation.
