What are the regulations for using low beams at 150 meters during nighttime oncoming traffic?

[StWalter]

The reasons and regulations for using low beams at 150 meters during nighttime oncoming traffic are as follows: 1. Regulation 1: When two vehicles approach each other at night at a distance of more than 150 meters, they should alternately switch between high and low beams to facilitate observation of the road ahead. 2. Regulation 2: When approaching oncoming traffic at night, drivers must switch to low beams at a distance of 150 meters or more from the other vehicle. 3. Regulation 3: If the oncoming vehicle does not turn off its high beams during nighttime oncoming traffic, drivers may alternately use high and low beams to signal the other vehicle. 4. Regulation 4: The headlights of oncoming vehicles at night can cause glare, so drivers should reduce speed or stop.
