At what distance should you switch your vehicle's lights from high beam to low beam when approaching another vehicle?

The correct practice is to switch your vehicle's lights from high beam to low beam when you are approximately 150 meters away from an oncoming vehicle. This distance is important for ensuring that you do not blind or impair the vision of the other driver with your high beams. High beams are designed to illuminate the road ahead further, but they can be particularly harsh on other drivers' visibility. Consequently, maintaining a safe distance allows both drivers to see clearly, while also complying with road safety regulations that aim to minimize glare and maintain safe driving conditions. Awareness of this distance enhances overall safety on the road by ensuring that visibility is preserved for all users.
