When must you use dipped headlights while driving?

Using dipped headlights is essential for ensuring safety while driving under specific conditions. It is particularly important in poor visibility situations, such as fog, heavy rain, or snow, where the light helps illuminate the road and make your vehicle more visible to other drivers. Additionally, when driving at night, dipped headlights provide adequate illumination without blinding oncoming drivers, which is crucial for maintaining safety on the roads.

In contrast, driving during sunny weather does not typically necessitate the use of dipped headlights, as natural daylight usually offers sufficient visibility. The requirement to use dipped headlights is not limited to urban areas; it applies across all driving environments, including rural and highway settings. Therefore, using dipped headlights only while driving on highways neglects the need for safety in other places as well. Overall, the correct answer emphasizes the importance of using dipped headlights in conditions where visibility is compromised, thereby enhancing overall road safety for everyone.
