When must you turn on your vehicle headlights?

Turning on your vehicle headlights when visibility is less than 100 metres is essential for safety and compliance with road regulations. This guideline is in place because reduced visibility can significantly impact your ability to see other vehicles, road signs, and obstacles. It's crucial for ensuring that you can react in time to any potential hazards on the road. Headlights not only help illuminate the road ahead for you but also make your vehicle more visible to other drivers, which is especially important in conditions such as heavy fog, rain, or nighttime driving.

Other conditions might require headlights, such as nighttime or specific weather scenarios, but the rule regarding visibility less than 100 metres prioritizes safety in situations where sight is compromised. This helps maintain a standard for safe driving practices in various situations that might be dark or obscured, ensuring that all road users can navigate safely and effectively.
