On the side of a double yellow line with dashed markings; at an intersection on the side with dashed lines; or within grid markings—these are situations where you can make a U-turn without needing to observe traffic lights. The specifics are as follows: On one side of a double yellow line: If a vehicle is traveling on the side of a double yellow line on a highway, it can make a U-turn without checking traffic lights. At an intersection on the side with dashed lines: In this case, the vehicle can immediately make a U-turn from the dashed centerline without needing to pass through a crosswalk or enter the intersection. Within grid markings: As long as there are no barriers in the middle of the grid markings, after yielding to normally moving vehicles, the motor vehicle can complete a U-turn at this location without observing traffic lights. U-turn rules regarding traffic lights: Intersections with U-turn signals: U-turns are permitted. At intersections with U-turn signals on traffic lights or U-turn signs on the lane, a U-turn can be made after ensuring safety. Intersections without U-turn signals but with left-turn signals: U-turns are permitted. Drivers can use the left-turn lane to make a U-turn at the central median or when approaching the intersection, provided it does not interfere with normal traffic flow. Crosswalk areas: U-turns are prohibited. U-turns cannot be made on crosswalks or pedestrian crossings. However, you may cross the crosswalk when the light is green and then make a U-turn afterward—never on the crosswalk itself. Motor vehicles must not make U-turns at locations with "No U-turn" or "No Left Turn" signs or markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or other hazardous sections of the road.
