When should you use your headlights?

Using headlights from sunset to sunrise and in adverse weather conditions is essential for ensuring visibility and safety on the road. During nighttime hours, headlights illuminate the road ahead, helping you see and be seen by others. This is crucial because darkness can significantly reduce visibility, making it difficult to spot obstacles, pedestrians, or other vehicles.

In adverse weather conditions such as rain, fog, snow, or heavy cloud cover, visibility can be further compromised, making the use of headlights even more critical. In these situations, headlights not only help you see better but also make your vehicle more visible to other drivers, reducing the chances of accidents.

The choice indicating the use of headlights at all times during the day is generally unnecessary under normal conditions, since daylight often provides sufficient visibility without additional lighting. Using headlights only on highways or at twilight does not account for the various other situations where visibility is diminished, leading to potential safety hazards. Thus, option B encapsulates the correct circumstances for the appropriate use of headlights, aligning with safe driving practices.
