When is it advisable to use high beams while driving?

Using high beams while driving is advisable when there is no oncoming traffic present. High beams provide increased visibility at greater distances, allowing a driver to see further down the road and identify potential hazards. This enhanced illumination can be particularly beneficial on poorly lit roads or in rural areas where streetlights are absent.

In situations where there is oncoming traffic, high beams can cause glare, impairing the vision of other drivers. Therefore, it's crucial to switch to low beams when encountering vehicles traveling in the opposite direction or when following another vehicle closely.

The other scenarios presented, such as driving in foggy conditions, during the day, or while in city limits, typically do not warrant the use of high beams. Fog can scatter light from high beams, making visibility worse, and bright daylight or well-lit urban environments do not necessarily require high-intensity lighting for safe travel.
