The Croatian classification includes several classes of highways:[1] Other than the motorway routes, the national road classification includes the following enumerated categories of routes in the national highway system, with decreasing order of priority:[2] Road operators differ according to the classification system: The designated motorways are operated by three different concessionaires.
[1][3] The primary high-speed motorways are called autoceste (Croatian pronunciation: [ˈaʊtotsesta]; singular: autocesta), and they are defined as roads with at least three lanes in each direction (including hard shoulder) and a speed limit of not less than 80 kilometres per hour (50 mph).
[5] Motorways in Croatia are defined by the Ministry of Maritime Affairs, Transport and Infrastructure.
As of 2021[update], the Cerovlje–Rijeka section of A8, the remaining part of the Istrian Y, is being upgraded from semi-highway status.
The expressways include both incomplete motorways, built in stages,[8] and some state roads (with either limited access, more than two traffic lanes, grade-separated intersections or any combination thereof).
There are even some instances of county roads which may be regarded expressways such as Jadranska Avenue (Ž1040).
State roads in Croatia are assigned one, two or three digit numbers which generally comply with the following pattern[34] (although there are some exceptions to the rules): At the moment the state roads in Croatia have a combined length of 6,867.7 kilometres (4,267.4 mi).
At the entrance on the motorway, the user picks up the entrance card (or a record recorded on the ENC device) and the payment is made on exit toll stations according to the length of the trip.
