When driving at night, when should you dim your headlights?

Dimming your headlights when another vehicle approaches or when following another vehicle is essential for safe nighttime driving. High beams can significantly blind other drivers, making it difficult for them to see the road and react properly. By switching to low beams, you ensure that you provide adequate illumination for your own visibility while reducing glare for other drivers. This practice enhances overall road safety, as it allows all users to have a clearer view of their surroundings.

Driving through intersections typically does not require headlight dimming unless another vehicle is present, and using high beams constantly can create hazardous conditions for others on the road. Foggy conditions do indeed necessitate adjustments in headlight use, but this situation is specific and does not encompass the broader need for dimming headlights when facilitating the safety of fellow drivers.
