When is it deemed appropriate to use high beams?

Using high beams is appropriate in rural areas where there is no oncoming traffic and no streetlights because it significantly enhances visibility. High beams illuminate the road much more effectively than low beams, allowing drivers to see further ahead and spot any potential hazards or obstacles in their path. This increased visibility is particularly beneficial in rural settings, where the lack of artificial lighting makes it difficult to see clearly.

In contrast, using high beams in well-lit urban areas would be inappropriate, as the streetlights provide sufficient illumination, and high beams could cause glare for other drivers and pedestrians. Using high beams at all times is not advisable, as they can be distracting to other road users and could impede their vision. Driving in heavy rain also presents challenges; using high beams can create glare that actually reduces visibility due to the reflection of the light on the rain droplets. Therefore, the conditions of rural areas without traffic perfectly align with when high beams should be used for optimal road safety.
