At what distance should you dim your high-beam headlights when approaching another vehicle?

Dimming high-beam headlights when approaching another vehicle is important for the safety of all road users. The correct distance to dim your high-beam headlights is 300 feet. This distance is specified in driving laws to ensure that oncoming drivers are not blinded by bright lights, which can create dangerous driving conditions.

By dimming your lights at this distance, you provide sufficient time to ensure that oncoming vehicles can safely adjust their own vision, reducing the likelihood of accidents. High-beam headlights are intended for use in situations where there is no oncoming traffic, as they illuminate the road more effectively but can hinder the visibility of other drivers when used improperly.
