The unit (1) has a connection element (3) i.e. hook, provided at a flexible carrier element (2), where length (L) of the unit corresponds to width of an emergency lane of a road. A cross-section of the carrier element is formed such that shock or vibration is produced in a motor vehicle when the vehicle is driven over the unit. A warning unit (4) i.e. optical warning unit, is arranged at the carrier element and produces an acoustic signal, the shock or the vibration in the vehicle when the vehicle is driven over the unit. The unit is arranged in a U-, V- or M-shape on the road. The warning unit is made of hollow or solid material, and the optical warning unit is designed as LED or an organic LED. The carrier element is designed as a rope, a tape, a flexible strand, a cable, a wire or a hose. An independent claim is also included for a method for protecting an accident site and an accident and/or breakdown vehicle. |
