[DiWalker]

Alternate between high and low beams to signal. The following are the relevant regulations on the use of vehicle lights: 1. Passing sharp bends at night: According to the Road Traffic Safety Implementation Regulations, when a motor vehicle passes a sharp bend, slope, arch bridge, crosswalk, or an intersection without traffic signal control at night, it should alternately use high and low beams twice to signal. When a motor vehicle approaches sections with limited visibility that affect safety, such as sharp bends or the top of a slope, or when overtaking or encountering an emergency, it should slow down and sound the horn to signal. 2. Poor lighting at night: When a motor vehicle is driving at night without streetlights, under poor lighting conditions, or in low visibility situations such as fog, rain, snow, dust, or hail, it should turn on the headlights, position lights, and rear lights. However, high beams should not be used when a following vehicle is driving close to the vehicle in front in the same direction. Motor vehicles driving in foggy conditions should turn on the fog lights and hazard warning flashers.
