What is the difference between a U-turn and a turn?

[Milton]

The difference between a U-turn and a turn is that a U-turn requires the vehicle to rotate 180 degrees, while a turn only requires a 90-degree rotation. Below are the relevant introductions for vehicle U-turns and turns: 1. U-turn precautions: When performing a U-turn, the vehicle should ensure not to cross the stop line of the left-turn lane at the intersection. Avoid occupying or pressing on traffic markings such as solid lane dividers, pedestrian crossings, guide lines, and safety islands. Do not obstruct the normal passage of other vehicles and pedestrians. 2. Turn precautions: When turning, the vehicle speed should be slow, and the steering wheel should not be turned too sharply to prevent excessive centrifugal force causing the vehicle to skid. If the vehicle skids, immediately release the accelerator pedal and turn the steering wheel toward the side of the skidding rear wheel. Once the vehicle resumes straight driving, straighten the steering wheel and continue driving.
