When is it safe to use high beam headlights?

Using high beam headlights is appropriate on open country roads with no other vehicles present. High beams provide increased visibility and allow you to see further down the road, which is particularly beneficial in areas without street lighting. In such environments, where there is minimal traffic, you can use your high beams to safely illuminate the road ahead, helping you detect potential hazards, animals, or obstacles.

In contrast, using high beams in urban areas with oncoming traffic can cause glare and impair the vision of other drivers, making it unsafe. Similarly, high beams should be turned off in foggy conditions, as they can reflect off the fog, rain, or snow, leading to reduced visibility. When following another vehicle, it's important to avoid using high beams as well, since they can distract or blind the driver in front of you, creating dangerous conditions on the road.
