When must you use your headlights when driving at night?

Using your headlights whenever visibility is poor or on unlit roads is vital for ensuring safety while driving at night. Headlights enhance the driver's ability to see the road, obstacles, and other vehicles, which is particularly important in low-light conditions. Poor visibility might be due to factors such as fog, rain, or the absence of street lights, making it challenging to spot potential hazards.

While it is advisable to use headlights at all times for maximum safety, particularly in areas where visibility can change suddenly, specifically using them in poor weather conditions or on unlit roads addresses the crucial safety need. This ensures that not only can drivers see better, but they also make themselves visible to others, reducing the risk of accidents. The other choices do not encompass the full range of conditions under which headlights should be used, potentially leading to dangerous scenarios if a driver only follows those limited guidelines.
