In the Czech Republic, the European route numbers are only additional, and they are always concurrent with the state route numbering, usually highways or first-class roads. In the state numbering system, concurrences exist only in first-class and second-class roads; third class roads do not have them. The local term for such concurrences is (from the French word ). In the road register, one of the roads is considered the main ("source") road and the others as the "péaging" (guest) roads. The official road map enables a maximum of five concurrent routes of the intrastate numbering system. Cycling routes and hiking routes are often concurrent.
