When should dipped headlights be used?

Answer: C — When it is dark or visibility is poor

Dipped headlights should be used when it is dark or visibility is poor because they help ensure that your vehicle is visible to other road users and enhance your ability to see the road ahead. This includes times when natural light is insufficient, such as during nighttime, in fog, heavy rain, or snow. Dipped headlights are specifically designed to provide sufficient illumination without causing glare to oncoming drivers, making them crucial for safe driving in adverse conditions. Using dipped headlights in such circumstances can improve overall road safety, as it allows you to see and be seen more clearly by others on the road. This practice contributes to preventing accidents that might occur due to poor visibility. Conditions like fog or heavy precipitation can significantly reduce how far ahead you can see, and using dipped headlights is a proactive measure to mitigate these risks.
