What lights should be used when passing through an arched bridge slope?

[CadenAnn]

When passing through an arched bridge slope, you should use the high and low beams alternately. According to the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China, when a motor vehicle passes through sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signal control at night, it should alternately flash the high and low beams twice as a signal. When a motor vehicle approaches sections such as sharp curves or the top of slopes that affect safe sight distance, or when overtaking or encountering emergencies, it should slow down and sound the horn as a signal. The main challenge of driving at night is poor visibility, so lights must be used. Generally, low beams are sufficient for normal nighttime driving. Turn signals must be used when turning. If you encounter a poorly lit road with insufficient lighting ahead, you should switch to high beams.
