When should you dim your headlights?

Dimming your headlights is essential for ensuring safety and visibility on the road, particularly in situations where bright lights can impair the vision of other drivers. The correct choice emphasizes the importance of dimming headlights during city driving and when following another vehicle closely, typically within 500 feet.

In city environments, where there are streetlights and other vehicles, using high beams can create glare and hinder the ability of drivers ahead to see clearly, making dimmed lights a safer choice. When following another vehicle, bright headlights can reflect off the rearview mirror and blind the driver in front, increasing the risk of accidents. By dimming your headlights in these circumstances, you promote a safer driving environment for everyone on the road.

Other options might suggest dimming in different scenarios, but they do not encompass the specific guidelines related to urban driving and following distances that significantly impact road safety.
