When should you dim your high beams if another vehicle is approaching?

Dimming your high beams when another vehicle is approaching is important for safety and visibility. The correct distance to dim your high beams is 500 feet. This distance gives the oncoming driver an adequate chance to see without being blinded by excessive brightness from your headlights. High beams can significantly impair visibility for other drivers, particularly at night, so dimming them at this distance helps maintain safety for everyone on the road.

Being aware of this distance encourages responsible driving behavior, as it allows for a seamless shared use of the roadway. In comparison, the other distances provided (300, 400, and 600 feet) do not align with the standard guideline, which is established to ensure effective visibility management between drivers. Therefore, knowing when to dim your headlights helps ensure a safer driving environment.
