When should you dim your headlights when meeting or following a vehicle at night?

Dimming your headlights when meeting or following another vehicle at night is crucial for ensuring safety and visibility. The correct answer is that you should dim your headlights when you are within 500 feet of an oncoming vehicle or when you are within 200 to 300 feet of a vehicle you are following.

This distance of 500 feet provides enough room for the driver of the oncoming vehicle to adjust to the change in lighting. High beams can be blinding to other drivers, creating a hazardous situation. By dimming your lights, you help minimize glare, allowing both drivers to see clearly without impairing each other's visibility.

While other distances such as 300, 400, and 600 feet have been suggested, the established guideline is specifically set at 500 feet due to its effectiveness in promoting road safety. This ensures that all drivers can navigate the road safely at night, reducing the chances of accidents caused by impaired visibility.
