When must headlights be used?

Headlights must be used from sunset to sunrise to ensure visibility and safety while driving in low-light conditions. This requirement helps drivers see the road and any obstacles clearly, while also making the vehicle more visible to others. During nighttime driving, natural light is significantly reduced, and headlights are crucial for illuminating the path ahead and increasing the safety of all road users.

Using headlights only during adverse weather or only on rural roads does not account for the fact that visibility can be compromised at night regardless of weather conditions or location. Daytime use of headlights may be beneficial for visibility but is not mandated under this specific context. Thus, the guideline to use headlights from sunset to sunrise is designed to create a standard for safe driving practices during hours of reduced natural light.
