On which road sections can a vehicle make a U-turn?

[VanHarmony]

Road sections where a vehicle can make a U-turn include: 1. Intersections with U-turn signs; 2. Intersections without explicit no U-turn or no left-turn signs; 3. Within yellow grid lines. Precautions for U-turns: 1. Intersections with U-turn signs and markings allow U-turns; 2. If there is a left-turn lane without a no U-turn sign, you can cross the zebra crossing and use the left-turn lane to make a U-turn; 3. If there is a dashed line between the double yellow lines and the front end of the zebra crossing, you can use the left-turn area to make a U-turn before the zebra crossing. The methods for a vehicle to make a U-turn are: 1. Proceed forward according to the traffic light signals. If there is a zebra crossing at the intersection, turn the steering wheel to the right when the vehicle enters the zebra crossing, and observe through the right rearview mirror whether any vehicles are approaching from the right; 2. When the vehicle has completely left the zebra crossing, the turning radius on the road will increase. At this point, turn the steering wheel fully to the left and continue driving to complete the U-turn.
