When is it appropriate to use high beams?

Using high beams is appropriate on open roads with no oncoming traffic because it provides maximum visibility. High beams illuminate a longer distance ahead, allowing drivers to see potential hazards, road signs, or animals more clearly. This is particularly beneficial in rural or less populated areas where street lighting may be limited.

In contrast, using high beams in heavy rain, heavy traffic, or urban areas can create visibility problems. In rain, the light can reflect off the water droplets, causing glare and reducing visibility. In heavy traffic, high beams can dazzle other drivers, leading to dangerous situations. Similarly, in urban areas, streetlights typically provide enough illumination, making high beams unnecessary and potentially distracting to other road users.
