The traffic rules describe how a road user must act on the public road, which includes obligations but also advice on how to drive sensibly and safely. All road users must know and apply the traffic rules.
The public road contains the lane, bicycle path, footpath and roadside and goes all the way to the canal or a property. On public roads we are allowed to drive with all vehicles (if no restrictions are imposed by traffic signs).
The lights on a vehicle have different functions and are an important part of road safety. The lights of your vehicle improve visibility at night. They also ensure that other road users can better see the presence, position, size and direction of your vehicle.
