When is it appropriate for a driver to use high beam headlights?

Using high beam headlights is appropriate in situations where there is limited visibility and little to no oncoming traffic. On rural roads without streetlights, conditions are often darker, making it harder to see without additional light. High beams help illuminate the road ahead, allowing drivers to spot potential hazards or obstacles more easily.

In contrast, using high beams in heavy rain or fog can cause glare and reduce visibility further for the driver and anyone else on the road, as the light reflects off the precipitation. In school zones, it's critical to maintain a lower speed and keep headlights at a standard setting to ensure the safety of pedestrians and children. During daylight hours, high beams are generally unnecessary since natural light is sufficient for visibility. Thus, the use of high beams is specifically advantageous on dark, rural roads where they enhance safety and awareness.
