When must motor vehicles have their headlamps illuminated?

Motor vehicles must have their headlamps illuminated between sunset and sunrise to ensure visibility and safety on the road during low-light conditions. This requirement is fundamental because nighttime driving poses increased risks due to reduced visibility, making it harder for drivers to see other vehicles, pedestrians, and road signs.

While there are moments outside of this timeframe when headlights are also necessary—such as in inclement weather or when visibility is poor—the law specifically mandates headlamp use during hours of darkness, thus ensuring that all vehicles are clearly visible to one another. This regulation helps prevent accidents and promotes safer driving practices.

Other scenarios may require the use of headlamps, but this specific time frame is crucial as it addresses the primary concern of visibility during nighttime driving.
