When are dipped headlights typically required?

Dipped headlights are typically required from just after dusk to just before dawn, as this is when visibility is significantly reduced due to low-light conditions. Using dipped headlights during these times not only increases your own visibility to other road users, but it also ensures that you are more easily seen in conditions where natural light is insufficient. This practice enhances safety for all on the road.

While dipped headlights can also be utilized in other circumstances, such as during poor weather or on highways when visibility is compromised, the primary legal requirement is centered around the times when natural daylight is minimal. Bright daylight does not necessitate the use of dipped headlights, as they would be less effective in bright conditions. Similarly, using dipped headlights only on rainy days or exclusively when on highways does not cover the full scope of their required use during low-light periods.
