When must you use your headlights while driving?

Using your headlights in any adverse weather conditions is vital for ensuring visibility and safety on the road. When driving in conditions such as rain, fog, snow, or sleet, visibility can be significantly reduced, making it difficult for other drivers to see your vehicle. Headlights help illuminate the road and make your vehicle more visible to others, reducing the risk of accidents.

While it is important to use headlights at night, relying solely on nighttime conditions would overlook crucial safety practices that are necessary in various weather scenarios. Similarly, limiting the use of headlights to highways or exclusively to tunnels does not cover the broader requirement to use headlights whenever visibility conditions have worsened due to weather or other factors. Therefore, the correct approach is to use headlights in any adverse weather conditions, ensuring that all road users can see and react to each other effectively.
