Should headlights be alternated between high and low beam or just low beam when meeting another vehicle?

When meeting another vehicle, headlights should be switched to low beam. Car lights not only serve the purpose of illumination but also act as a communication tool between drivers. However, improper use of car lights can also cause disturbances. The correct way to use high and low beam headlights: High beams illuminate a higher area than low beams, allowing drivers to see further down the road. Therefore: 1. It is best to use low beams on well-lit roads or sections with good visibility; 2. If the road ahead is unlit and completely dark, use high beams; 3. When encountering another vehicle, always remember to switch to low beam. If the oncoming vehicle does not switch to low beam, slow down appropriately.
I've been driving long distances for ten years and have plenty of experience with nighttime oncoming traffic. According to regulations and driving habits, when encountering oncoming vehicles, you must switch to low beams rather than alternating between high and low beams. Why? High beams are too bright and can instantly blind the oncoming driver, like a camera flash, which can easily lead to accidents. Alternating between high and low beams can distract the other driver and increase the risk. I remember once driving on a mountain road at night when I accidentally forgot to switch my lights. The oncoming driver honked aggressively to warn me, and only then did I snap out of it and switch to low beams, avoiding a collision. Now, whenever I see oncoming headlights, I automatically adjust to low beams—this habit keeps me safe. I also advise new drivers to develop the reflex of switching lights early because low beams are bright enough even on well-lit city roads—don’t cut corners for convenience. Safety first—when everyone follows the rules, the road runs smoother.
