At what distance should you dim your high beams for an oncoming vehicle?

Dimming your high beams for an oncoming vehicle should occur at a distance of 150 meters. This distance is established to ensure that the glare from your headlights does not impair the vision of the other driver, allowing them to maintain safe control of their vehicle.

High beams are designed to illuminate the road much farther ahead, which can be beneficial in darkness or low-visibility conditions. However, when another vehicle approaches, the intense light can cause temporary blindness for the oncoming driver. Dim your high beams at this specified distance to promote safety on the road for both yourself and others. Generally, guidelines for headlight use are aimed at minimizing risks and ensuring clear visibility for all users of the road.
