When should headlights be used by drivers?

Headlights should be used when it's dark and visibility is poor. This is crucial for ensuring that you can see the road and any potential hazards while driving, and it also allows other drivers to see you. Poor visibility can occur not only at night but also during times such as dusk, dawn, and in inclement weather conditions such as rain or fog.

Using headlights only during heavy rain or just after sundown fails to address the various situations where visibility can be compromised. For instance, even during the day, fog or heavy cloud cover can significantly reduce visibility. While driving at night, effective use of headlights is essential for safety. The graduate from the idea of using them only at specific times like after sundown to understanding that they are crucial whenever conditions require greater visibility.

Thus, the best practice is to turn on headlights whenever visibility is inadequate to enhance both your safety and that of those around you on the road.
