When using high-beams, within how many feet of oncoming traffic should you dim your headlights?

200 feet
300 feet
400 feet
500 feet

The correct answer is: 500 feet

When using high-beams, it is important to dim your headlights within 500 feet of oncoming traffic to ensure safe visibility for both drivers. High-beam headlights are designed to illuminate the road far ahead, but they can create significant glare for other drivers, making it difficult for them to see. Dimming your headlights in this situation allows oncoming drivers to maintain their visibility and reduces the chances of accidents caused by temporary blindness from excessive glare. The guideline of 500 feet is established based on the distance at which the bright light from high-beams can be perceived by the driver of approaching vehicles. This distance is a critical safety measure to aid in nighttime driving, as it promotes a cooperative and safe driving environment for everyone on the road.
