When is it acceptable to use your high beams?

Using high beams is appropriate on dark roads when no other vehicles are present. High beams provide increased visibility, allowing drivers to see further ahead, which is particularly beneficial in areas without street lighting. This enhances safety by enabling identification of potential hazards that wouldn't be visible with standard headlights.

In conditions such as foggy weather, high beams can cause light to reflect back to the driver, reducing visibility instead of enhancing it. Well-lit streets don't require high beams, as the existing lights provide sufficient illumination. Similarly, when driving in traffic, using high beams can be blinding to other drivers, creating a dangerous situation. Therefore, reserving high beams for isolated, dark roads is the best practice for safe driving.
