What is the minimum distance from an oncoming car to safely use high beams?

The minimum distance from an oncoming car to safely use high beams is 500 feet. This guideline helps ensure that the bright illumination of high beams does not blind or distract the driver of the oncoming vehicle. When high beams are used at this distance, it allows enough time for both drivers to adapt their visibility, thereby enhancing safety on the road.

Staying within this distance maintains proper visibility while mitigating the risk of causing temporary vision impairment to oncoming drivers, which can lead to dangerous situations. It's important for drivers to remember this rule to promote safe driving practices during nighttime or low-light conditions.
