Under what conditions must you use your headlights?

Using headlights in rain, fog, or any visibility-reducing condition is essential for ensuring safety on the road. When visibility is compromised due to weather conditions like rain, fog, or snow, headlights help illuminate the roadway and make your vehicle more visible to other drivers. It is important to remember that standard headlights are designed to pierce through fog and heavy precipitation better than just relying on daytime running lights, which may not be effective in such conditions. This practice supports safe driving and enhances overall traffic safety by reducing the likelihood of accidents that can occur when drivers cannot see one another clearly.

While headlights are typically associated with nighttime driving, they are equally vital during the day in adverse weather conditions to maintain visibility and alertness on the road.
