When making a U-turn, the maximum speed should not exceed 30 kilometers per hour, and the left turn signal must be activated in advance to avoid obstructing other normally moving vehicles and pedestrians. Permissible situations for making a U-turn: Intersections with U-turn signs: If there is a clear U-turn sign at the intersection, a U-turn can be made. 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 without hindering other vehicles or pedestrians. Intersections without explicit prohibition of U-turns or left turns: If there is no explicit sign prohibiting U-turns, a U-turn can be made. 'No explicit prohibition' means the absence of 'No U-turn' signs, 'No Left Turn' signs, or solid center lines, allowing a confident U-turn. Yellow grid lines also permit U-turns: Yellow grid lines are no-parking zones, typically marked at intersections prone to congestion due to temporary stops, entrances of important institutions, or other necessary locations. Parking (including waiting at traffic lights) on these lines is a violation. Although stopping is prohibited, U-turns are allowed in yellow grid line areas unless there is a central barrier, making them 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 even if left turns are prohibited, but 'No U-turn' is not the same as 'No Left Turn.' Points to note when making a U-turn at an intersection: Observe road markings. If they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable spot. If there is a 'No Left Turn' sign, even without a 'No U-turn' sign, U-turns are not allowed at that intersection because U-turns inherently involve a left turn. 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. Only proceed with a U-turn if it does not interfere with their normal movement, or you will bear full responsibility for any accidents. Near intersection stop lines, lanes usually have guiding arrows. The leftmost lane may not always have a left-turn arrow; if it has a straight arrow, U-turns are prohibited even without explicit 'No U-turn' signs.
