When should you dim your headlights?

Dimming your headlights is essential for ensuring the safety of both you and other road users. The appropriate time to dim your headlights is when you are following another vehicle. High beams can be blinding to the driver in front of you, reducing their visibility and increasing the risk of a collision. By switching to low beams, you help maintain a safer driving environment while still allowing yourself to see the road ahead clearly.

While it is also advisable to dim your headlights in other situations, such as when driving in fog or during nighttime in rural areas, the specific context of following another vehicle poses a greater immediate risk of glare. Daytime driving typically does not require the use of headlights to be dimmed since the sun provides sufficient light, and using high beams during the day does not usually have the same adverse effects on other drivers.
