When is it appropriate to use high beam headlights?

Using high beam headlights is appropriate on dark roads when there are no oncoming vehicles. High beams provide a greater amount of light and a longer range of visibility, which can be critical in rural or poorly lit areas where there is less ambient light. This enables drivers to see further down the road, helping to identify potential hazards, such as animals or obstacles that may not be visible with low beam headlights.

In contrast, using high beams in heavy rain can cause glare and decrease visibility for both the driver and other road users. Similarly, in city streets at night, streets are often lit by street lights, making high beams unnecessary and potentially blinding for other drivers and pedestrians. During foggy conditions, it is better to use fog lights or low beams, as high beams can reflect off the moisture in the fog, causing a problematic glare and reducing visibility. Thus, the correct use of high beam headlights significantly contributes to enhancing safety on the road in suitable conditions.
