When is it appropriate to use high beam headlights?

High beam headlights are designed to illuminate the road in front of a vehicle more brightly and further than low beam headlights. They can be particularly useful in situations where there is little to no ambient light and no other vehicles around. Using high beams when there is no oncoming traffic is appropriate because it enhances visibility for the driver without causing glare or distractions to others on the road. This capability allows for better detection of potential hazards, road signs, and obstacles at greater distances, which is crucial for safe driving, especially on dark, rural roads.

In contrast, high beams should be avoided in daylight, during fog, and in light rain, as these conditions can reduce visibility and the effectiveness of high beams or produce glare that could impede the visibility of other drivers.
