When is it appropriate to use high beams while driving?

Using high beams while driving is appropriate on open roads with no oncoming traffic because high beams provide better visibility and illuminate a wider area ahead. This is particularly beneficial in rural or less populated areas where street lighting is minimal and there are fewer vehicles. High beams help drivers see further down the road, which can be critical for spotting obstacles or hazards in a timely manner.

In contrast, using high beams in heavy traffic, residential areas at night, or when driving in fog is inappropriate because it can obstruct the vision of other drivers and create dangerous situations. High beams can cause glare for oncoming drivers or those in close proximity, which is why they should be dimmed in such conditions. In fog, the light reflects off the moisture in the air, reducing visibility further. Understanding when and where to use high beams is crucial for safe driving and maintaining good driving etiquette.
