An electrically conductive carriageway marking includes a carrier strip, electrically conductive wires extending along the carrier strip, an electrically insulating covering layer covering the wires, a power feed formed by an interface connecting the wires to a supply line, and interfaces arranged spaced apart from each other along the carriageway marking and having electrical contact areas. The contact areas include contact elements protruding laterally from the carriageway marking, and the supply line is connectable to a first contact area of the wires and a second contact area of the wires by electrical contacts that can be tapped off. In the region of the contact areas the covering layer is formed by a detachable adhesive protective strip, and the protective strip is connected via predetermined break points or perforations to adjoining sections of the covering layer, and the wires are exposed by detaching the protective strip.
