Driving with parking lights only (in place of headlights) is against the law.

Driving with parking lights only instead of using headlights is indeed against the law. Parking lights are intended to make a vehicle more visible while it is parked on the side of the road, particularly in low-light conditions, but they are not designed to provide adequate illumination for driving. Headlights are essential for safely navigating the road at night or in poor visibility conditions, as they illuminate the roadway and help the driver to see and be seen by others. Failing to use headlights while driving could lead to reduced visibility, increasing the risk of accidents. Therefore, using parking lights in place of headlights violates traffic regulations aimed at ensuring safety on the road.
