The invention relates to a system (1) for giving priority to a special vehicle (2) at traffic-light-controlled nodes (K) in a road network. Said system comprises traffic lights (30) installed at the nodes (K), with signal transmitters (31) for outputting go and stop signals and with control units (32) for controlling the signal transmitters (31) according to a signal program that is influenceable by go requests (MG). A vehicle device (20) carried in the special vehicle (2) comprises a memory unit (22) for overwritably storing reporting points (P1) associated with the nodes (K), a positioning unit (24) for continually determining the current local position (Tn-2, Tn-1, Tn) of the special vehicle (2), a computing unit (23) for detecting passage through a reporting point (P1) by the special vehicle (2), and a communication unit (21) designed so as, when passage through a reporting point (P1) is detected, to generate a request message (MD) and to send the latter to a traffic computer centre (50) of the road network by way of a cellular mobile radio network (MC) and/or to a communication device (40) of the node (K) to be crossed by way of a local area radio network (NL). This provides a flexibly usable prioritization system for special vehicles.
