Under What Circumstances Should Low Beam Headlights Be Used?

[Emily]

Situations requiring the use of low beam headlights include: 1. When encountering other vehicles or pedestrians, switch to low beam headlights. 2. When unfamiliar with the road conditions and needing to read road signs or other indicators, high beam headlights may be used but should be quickly switched back to low beam. 3. When overtaking another vehicle, the left turn signal should be activated in advance, and the driver should alternate between high and low beams or use the horn to alert the vehicle ahead to yield. 4. When driving in relatively dark areas without streetlights, low beam headlights must be turned on. In cases of heavy fog, snow, or rain that obstruct visibility, low beam headlights must also be used even during daytime.
