According to the "Road Traffic Safety Law", not using the turn signal when making a U-turn results in: 1 point deduction; fine: 100 yuan. Other situations that result in a 1-point deduction include: not using lights as required; not meeting vehicles as required; motor vehicles carrying cargo exceeding the prescribed length, width, or height; motor vehicles driving on the road without inspection qualification marks, insurance marks, or without carrying the vehicle license and driver's license. Article 57 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China states that motor vehicles shall use turn signals as follows: When turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, the left turn signal shall be turned on in advance; When turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside, the right turn signal shall be turned on in advance. Turn signals: Must be turned on when the vehicle is turning, flashing intermittently to alert vehicles and pedestrians around. The timing of turning on the turn signal should be well controlled, and it should be turned on about 30 to 100 meters before the turning point. Situations where U-turns are allowed: 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 signal light, the U-turn must be made according to the signal light. If there is no signal light, a U-turn can be made based on the specific situation, provided it does not hinder 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 of U-turns" means that as long as there is no "No U-turn sign," "No left turn sign," or the center line is not solid, 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 temporary parking congestion, 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 a violation. Although vehicles cannot stop in the yellow grid line area, U-turns are allowed. As long as there is no central isolation barrier, the yellow grid line is equivalent to "U-turn allowed." Intersections with U-turn signal lights: This is easy to understand. If there is a U-turn signal light, you must follow the signal light and only make a U-turn when it is green. When "No left turn" and "U-turn allowed" signs appear together: U-turns are allowed but left turns are prohibited. However, "No U-turn" is not the same as "No left turn." Things to note when making a U-turn at an intersection: Observe the road markings. If it is a solid line, U-turns are not allowed under any circumstances, and you should continue driving to find a suitable place 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 a U-turn must 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 make the U-turn without interfering with their normal driving. Otherwise, you will bear full responsibility for any accident. Generally, near the intersection stop line, lanes are marked with guiding arrows for vehicles to choose lanes. The leftmost lane is not always marked with a left-turn arrow. On some roads, if there is a straight arrow, even if there are no explicit signs prohibiting U-turns, U-turns are not allowed.
