square sign identified the more common type that are at the same time priority roads (Vorrangstraße). Their vehicle users had the right of way already by the blue sign. A black number (typically greater than 100) on a yellow circular sign marks state roads that are not per se priority roads. Except in Vorarlberg, the former Bundesstraßen continue to be designated with the prefix B. The remaining Landesstraßen are prefixed with the letter L. On traffic signs the prefixes are usually not used, unlike the A (for Autobahn) and S (Schnellstraße). Roads numbered with fewer digits are generally of more importance in the road network. The former designation of more important Landesstraßen in several states as Landeshauptstraßen (LH, in Vienna: Hauptstraßen A) is only occasionally seen now on road and street maps.
