Under what circumstances should high beams be used?

[McGenesis]

High beams should be used in the following situations: 1. On roads without street lighting or with poor illumination, high beams can be used; 2. When unfamiliar with the road conditions and needing to read road signs or other indicators, high beams can be used, but should be quickly switched back to low beams; 3. When overtaking another vehicle, the left turn signal should be activated in advance, and high beams and low beams should be alternated or the horn should be sounded to alert the vehicle ahead to yield. Compared to low beams, high beams emit parallel light, which is more concentrated and brighter, allowing illumination of higher and more distant objects, greatly aiding the driver's visibility at night. High beams can improve visibility and expand the field of observation.
