What is a legal requirement regarding parking lights while driving at night?

When driving at night, it is vital to follow the legal requirement that parking lights must not be used as the sole source of illumination. This guideline is in place because parking lights are designed to indicate the presence of a parked vehicle to others, rather than to provide sufficient light for safe driving. Driving with only parking lights can limit visibility on the road, which poses significant safety risks for both the driver and other road users.

Using headlights is crucial during nighttime driving as they illuminate the road and improve the driver's visibility of other vehicles, pedestrians, and potential hazards. It's important for drivers to ensure they are using appropriate lighting that meets legal standards and facilitates safe navigation during low-light conditions.
