At what times are high beams typically permitted?

High beams are primarily permitted on open roads with no other vehicles present. This is because high beams provide a greater amount of illumination and visibility, which is particularly beneficial in areas where there is minimal or no traffic to distract or blind other drivers. Using high beams allows for enhanced visibility of any obstacles or road conditions ahead.

In contrast, using high beams in foggy conditions can create glare and reduce visibility, making it unsafe. Additionally, while high beams are generally used at night, their usage is not strictly limited to nighttime; they are primarily dependent on the surrounding conditions, such as the absence of other vehicles. Highways may allow for high beam use under similar conditions as other open roads, but they are not exclusively permitted in that environment. Hence, the best context for permissible use of high beams is during nighttime on open roads when there is no incoming traffic.
