When are dipped headlights typically required?

Dipped headlights are typically required from just after dusk to just before dawn because this timeframe encompasses conditions where visibility is reduced due to decreased natural light. Using dipped headlights during these hours helps illuminate the road ahead for the driver while allowing other road users to see the vehicle clearly. It's crucial for safety, as many accidents occur in low light conditions.

Utilizing dipped headlights enhances visibility without blinding other drivers, distinguishing them from main beam lights, which are more suitable for unlit roads. The other choices do not capture the primary function of dipped headlights in adverse lighting conditions throughout the day and night.
