What lights should be turned on in advance when a motor vehicle makes a U-turn?

[DePenelope]

When making a U-turn, the left turn signal should be activated in advance. Here is relevant information: 1. When there are no streetlights at night: When driving at night without streetlights, with poor lighting, or in low visibility conditions such as fog, rain, snow, dust, or hail, the headlights, position lights, and rear lights should be turned on. However, high beams should not be used when a following vehicle is driving close to the vehicle in front in the same direction. In foggy conditions, fog lights and hazard warning flashers should be activated. 2. When there is no traffic signal control: When driving through sharp curves, slopes, arched bridges, pedestrian crossings, or intersections without traffic signal control at night, the driver should alternately switch between high and low beams to signal. 3. When turning left or preparing to overtake: The left turn signal should be activated in advance when turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn.
