When should you dim your high beam headlights in relation to an oncoming vehicle?

Dimming your high beam headlights when an oncoming vehicle is 500 feet or more away is crucial for safety on the road. High beams are designed to provide maximum visibility on dark roads; however, they can significantly impair the vision of other drivers if used at an inappropriate distance.

By dimming your high beams at least 500 feet before the vehicle approaches, you help ensure that the oncoming driver is not blinded by your lights, which can lead to dangerous driving conditions or accidents. This practice is part of responsible driving and shows consideration for others on the road. It also aligns with traffic laws intended to promote safety for all users, including pedestrians and cyclists, who may also be affected by bright headlights.

Adhering to this distance helps maintain a safe driving environment and is a fundamental aspect of nighttime driving etiquette.
