Dimming your headlights when approaching another vehicle at night is crucial for safety. The correct distance to dim your headlights is 150 feet. This practice helps prevent blinding the driver of the oncoming vehicle with bright lights, ensuring a safer driving experience for both parties.

Dimming your headlights at this distance gives the oncoming driver sufficient time to adjust their visibility without experiencing glare, which can impair their ability to see the road clearly. This rule is in place to promote road safety and to prevent accidents that can arise from impaired vision due to bright headlights.

Option choices that suggest shorter distances, such as 50 or 100 feet, do not provide ample time for the other driver to adjust their sight, potentially leading to hazardous situations. On the other hand, while 200 feet might seem reasonable, it is excessive for the purpose since the guideline is formulated to balance visibility and courtesy on the road.
