What lights should be used when passing a slope at night?

[LaHarper]

When passing a slope at night, you should alternately use high beams and low beams. Here is a detailed introduction about alternately using high beams and low beams when passing a slope at night: 1. Use of high and low beams: When a motor vehicle passes sharp curves, slopes, arch bridges, crosswalks, or intersections without traffic signal control at night, it should alternately use high and low beams to signal. 2. Others: When a motor vehicle approaches sections that affect safe sight distance, such as sharp curves and the top of slopes, or when overtaking or encountering emergencies, it should slow down and sound the horn to signal. Motor vehicles driving in the same lane should maintain a safe distance from the vehicle in front to allow for emergency braking measures.
