When is it appropriate to use high beams?

Using high beams is most appropriate when driving in rural areas with no oncoming traffic because it provides greater visibility in low-light conditions. High beams illuminate the road ahead much more effectively than low beams, allowing drivers to see further distances and any potential hazards that may be present. This is especially useful on rural roads, which often lack street lighting.

In urban areas, using high beams can be blinding to other drivers and is considered unsafe, as there is generally more traffic and ambient light. During heavy rain, high beams can reflect off the water droplets and create glare, reducing visibility. Similarly, in foggy conditions, high beams will similarly reflect off the fog and cause a whiteout effect, making it harder to see. Therefore, the safest and most effective time to use high beams is in rural settings when there is no traffic that might be affected by the increased light.
