Under what circumstances should low beam headlights be used?

[HectorRose]

Low beam headlights should be used under the following circumstances: 1. When encountering other vehicles or pedestrians, you should switch to low beam headlights. 2. When unfamiliar with the road conditions and needing to read road signs or other markers, you may use high beam headlights but should quickly switch back to low beams. 3. When overtaking another vehicle, you should activate the left turn signal in advance and alternate between high and low beam headlights or sound the horn to alert the vehicle ahead to yield. 4. When driving in relatively dark areas without streetlights, you must turn on low beam headlights; if encountering heavy fog, snow, or rain that obstructs visibility, you must also turn on low beams even during daytime.
