Under what circumstances can you use high beam headlights?

High beam headlights are designed to provide increased visibility on open roads, particularly when there are no other vehicles around, such as on rural or less populated stretches of road. This is because high beams illuminate a greater distance and a wider area, helping drivers to see further ahead and detect potential hazards that may not be visible with regular headlights.

Using high beams is not advisable in heavy traffic or in urban settings where frequent stops and starts occur, as the bright light can distract or blind other drivers. Similarly, in foggy conditions, high beams can actually reflect off the moisture in the air, creating a glare that reduces visibility rather than improving it. Thus, the best practice is to use high beam headlights on open roads when there is no oncoming traffic to ensure safety and enhance visibility without affecting other drivers.
