When should you use your headlights while driving?

Using your headlights in low visibility conditions, such as heavy rain or fog, is crucial for both your safety and the safety of other road users. Low visibility can significantly impair your ability to see the road ahead, recognize hazards, and judge distances accurately. By turning on your headlights during these conditions, you not only improve your own visibility but also make your vehicle more visible to others, which can help prevent accidents.

Driving at night is also a common time for using headlights, but the question specifically emphasizes low visibility situations like rain or fog, which are equally dangerous. The other choices suggest limited or incorrect uses for headlights; for instance, only using headlights in rural areas or on the highway does not cover essential safety practices needed in various driving conditions. Using headlights properly enhances road safety for everyone, as they are an essential part of defensive driving.
