Under What Circumstances Are Vehicles Prohibited from Making U-turns?

[DallasDella]

There are no-left-turn or no-U-turn signs, no crossing solid lines to make U-turns, barriers or green islands in the middle of the road close to the stop line, and no U-turns on crosswalks. The relevant introductions are as follows: The relevant introductions are as follows: At intersections or road sections with dashed center lines: When there are no no-U-turn signs and no no-left-turn signs, vehicles can make U-turns. The absence of prohibitive signs is equivalent to allowing U-turns. When approaching an intersection, as long as there are no no-left-turn or no-U-turn signs, the driver can make a U-turn without paying attention to the traffic light changes. However, if there is a clear sign at the intersection stating "left turn allowed when green light is on" or "no left turn when red light is on," the U-turn is subject to the traffic light constraints and must comply with the instructions on the sign. U-turns are allowed on yellow grid lines: Parking is prohibited within yellow grid lines, and most drivers are now familiar with this rule. As long as there are no central barriers on the yellow grid lines, U-turns are allowed. Single solid yellow lines prohibit U-turns: Similar to intersections, road sections without no-U-turn signs allow U-turns. However, when making U-turns on road sections, pay attention to the solid or dashed nature of the center line. As long as it is a solid line, whether it is a single yellow line or double yellow lines, U-turns are prohibited.
