When is it appropriate to use high beams?

Using high beams is appropriate on open roads at night when no other vehicles are present because high beams provide a greater range of visibility, which is crucial in situations where there are no street lights or other sources of illumination. This allows drivers to see further ahead and better identify potential hazards, such as animals crossing the road or obstacles in the path. High beams should be used responsibly and switched to low beams when there is oncoming traffic or when following closely behind another vehicle, as the bright light can be blinding to other drivers.

In well-lit urban areas, high beams can create glare for other drivers and are generally unnecessary because streetlights provide adequate illumination. In foggy conditions, high beams can reflect off the moisture in the air, creating a wall of light that can obscure visibility even further. During daytime, the use of high beams is also unnecessary since natural daylight provides sufficient visibility. Therefore, the correct scenario for using high beams effectively focuses on open, dark roads with no traffic, maximizing safety and visibility.
