Headlights must be lighted from sunset to sunrise.

Headlights must be lighted from sunset to sunrise to ensure visibility and safety during conditions of reduced light. This requirement is in place because driving at night can be particularly dangerous due to decreased visibility, making it crucial for drivers to see the road clearly and for other drivers and pedestrians to see the vehicle.

Lighting headlights during this time helps illuminate the road ahead and signals to other road users that a vehicle is present, which significantly reduces the risk of accidents. Furthermore, the law is designed to promote safe driving practices by ensuring that all vehicles are equipped with functioning lights at appropriate times. This requirement also extends to times of poor weather conditions, such as fog or rain, which can occur during the day but still necessitate the use of headlights for safety.
