When should high beam headlights be used?

High beam headlights should be used on open roads without oncoming traffic because they provide maximum visibility for the driver. High beams illuminate a greater distance in front of the vehicle, which is particularly beneficial in rural or less populated areas where street lighting may be absent. This enhanced visibility helps identify potential hazards, including wildlife, road conditions, and other obstacles.

Using high beam headlights in situations with oncoming traffic or in city environments can be hazardous, as they may blind other drivers and create unsafe driving conditions. In contrast, in foggy conditions, the light from high beams can reflect off the moisture in the air, causing glare and making visibility worse, which is why low beam headlights are recommended in those situations.
