According to the "Road Traffic Safety Law", violators will be penalized with 3 demerit points. Going straight in a U-turn lane is considered a violation of the prohibition signs or markings for motor vehicles. However, if it is a combined U-turn and straight lane, no demerit points will be deducted. Permissible U-turn situations: Intersections with U-turn signs allow U-turns: 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, the U-turn must follow the signal. If there is no traffic light, a U-turn can be made based on the specific situation, provided it does not interfere with other vehicles or pedestrians. Intersections without explicit prohibition of U-turns or left turns allow U-turns: If there is no explicit prohibition of U-turns at the location, a U-turn can be made. Here, "no explicit prohibition of U-turns" means that as long as there are no "No U-turn signs," "No left turn signs," or solid lines in the middle of the road, a U-turn can be safely made. Yellow grid lines also allow U-turns: Yellow grid lines are actually no-parking grid lines painted at intersections prone to congestion due to temporary parking, important unit entrances, and other locations where they are needed. Any vehicle stopping on the no-parking grid line (including waiting for traffic lights) is considered a violation. Although vehicles cannot stop in the yellow grid line area, U-turns are allowed in this area. As long as there is no central road barrier, yellow grid lines are equivalent to "U-turn permitted." Intersections with U-turn traffic lights: This is straightforward. If there is a U-turn traffic light, you must follow the signal—only proceed on green. When both "No left turn" and "U-turn permitted" signs appear: U-turns are allowed, but left turns are prohibited. However, "No U-turn" is not the same as "No left turn." Precautions when making U-turns at intersections: Observe the road markings. If they are solid lines, U-turns are not allowed under any circumstances. Continue driving forward to find a suitable location for a U-turn. If there is a "No left turn" sign ahead, even if there is no mention of prohibiting U-turns, U-turns cannot be made at this intersection because the actions of left turns and U-turns are very similar, and U-turns always involve a left turn first. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, you cannot make a U-turn at this intersection. When making a U-turn, you must yield to vehicles going straight and only proceed if it does not interfere with their normal movement. Otherwise, you will bear full responsibility for any accidents. Generally, near the intersection stop line, lanes have guiding arrows for vehicles to choose their direction. The leftmost lane does not always have a left-turn arrow. On some roads, if there is a straight arrow, even without explicit "No U-turn" signs, U-turns are not allowed. U-turns cannot be made on pedestrian crosswalks, as this is also a violation.
