Within how many feet is a driver required to dim the high beams before meeting another vehicle?

The requirement to dim high beams when approaching another vehicle is established to ensure the safety and comfort of all drivers on the road. Dimming high beams within 500 feet is necessary because high beams can significantly impair the visibility of oncoming drivers. When faced with bright lights, a driver's ability to see the road and react to potential hazards can be drastically reduced, increasing the risk of accidents. Thus, the 500-foot distance serves as a standard to minimize glare and maximize safety for both the driver using the high beams and the driver of the approaching vehicle.
