At what distance must a driver switch to low beams when following another vehicle?

When following another vehicle at night, it is important to switch to low beams at a distance of 200 feet. This practice is essential to prevent blinding the driver in front of you with your headlights. High beams are designed to illuminate the road ahead more brightly and can cause visibility issues for other drivers, particularly when they are close. By switching to low beams at the 200-foot mark, you ensure that you maintain safe driving conditions for both yourself and the vehicle you are following. This distance is generally recommended because it allows enough space for traffic signals, road signs, and any potential hazards to be clearly visible without causing discomfort to the driver in front.
