When is it appropriate to use high beams?

High beams are designed to provide maximum visibility by illuminating a larger area further down the road. This is particularly useful in dark environments where there is little to no ambient light, making it easier for drivers to see obstacles, road signs, and other important features. Using high beams on dark country roads, especially when no other vehicles are present, is appropriate because it optimizes visibility without endangering others, as it minimizes glare that could affect oncoming drivers.

In contrast, using high beams in foggy conditions can create visibility issues because the light will reflect off the fog and reduce overall clarity. Similarly, in well-lit urban areas, the existing street lights provide adequate visibility, making high beams unnecessary and potentially blinding to other road users. Lastly, when following another vehicle closely, using high beams can be distracting and hazardous for the driver ahead due to glare in their rear-view mirror. Thus, using high beams is best reserved for dark, isolated areas where it enhances safety without impacting other road users.
