The probability of being caught making a U-turn on the sidewalk is particularly high. Intersections are the areas with the highest incidence of traffic accidents, and a large number of surveillance cameras are deployed there, making it extremely easy for violations to be recorded. The situations where U-turns are allowed are as follows: Presence of U-turn traffic lights or signs: When there is a U-turn traffic light at an intersection, a U-turn can be made when the U-turn indicator light is green. If there is a U-turn sign or a lane with a U-turn indicator, a U-turn can be made while ensuring the safety of oneself and others. U-turns are allowed at dashed lines: Whether it is a white dashed line or a yellow dashed line, U-turns are permitted. In the case of double yellow lines (one solid and one dashed), check whether the side you are on is the dashed line. If it is, a U-turn can be made safely; if it is a solid line, U-turns are not allowed. If you encounter double yellow lines (one solid and one dashed) at an intersection, you can make a U-turn on the dashed side, but you must not cross the stop line ahead. U-turns are allowed at yellow grid lines: Parking is prohibited in yellow grid areas, but as long as there is no central barrier, you can make a U-turn here after yielding to normally moving vehicles. U-turns are allowed on the dashed side of a green belt: When the front of the green belt is a dashed line, vehicles on that side can make a U-turn from there. If the front of the green belt is a solid line, vehicles must follow the traffic signal, cross the crosswalk, and then make a U-turn. Driving over the solid line or crosswalk to make a U-turn is prohibited. The situations where U-turns are prohibited are as follows: U-turns are prohibited where there are no-U-turn signs or no-left-turn signs: If there is a no-U-turn sign, U-turns are not allowed at that intersection. A U-turn is an extension of a left turn, so if there is a no-left-turn sign at an intersection, U-turns are also prohibited there. U-turns are prohibited at crosswalks: U-turns are not allowed at crosswalks. If U-turns are permitted at an intersection, you must cross the crosswalk before making a U-turn; you cannot make a U-turn while on the crosswalk. U-turns are prohibited when there is no left-turn lane: Even if you are in the leftmost lane, if there is no left-turn sign, U-turns are not allowed. U-turns are prohibited in the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any signs, U-turns are only allowed in the innermost left-turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a U-turn sign, you must wait for the green light and cross the stop line to make a U-turn.
