In what situation are you permitted to use high beam headlights?

Using high beam headlights is appropriate in situations where visibility is significantly reduced, such as driving in dark areas without oncoming traffic. High beams allow for a broader and longer range of illumination, which can help you detect potential hazards or obstacles on the road. This enhanced visibility is crucial on unlit roads where streetlights are absent, providing a clearer view of the surroundings.

In contrast, using high beams in foggy conditions can actually worsen visibility, as the light is scattered by the fog, creating a glare that makes it harder to see. Similarly, within city limits, where there are typically streetlights and other vehicles present, using high beams may dazzle other drivers and pedestrians. Lastly, following another vehicle while using high beams can impair the driver's vision in front of you, which is why it is not advisable. Thus, utilizing high beams in dark areas without oncoming traffic maximizes safety and visibility while minimizing glare for others.
