What you need to know about the toll in Croatia
Toll charges in Croatia must be paid for the use of all motorways (PDF) and are based on the number of driven kilometres. Vehicles of all categories in Croatia are liable to pay tolls, but the toll charges for vehicles in categories I, II, III and IV can be paid through DKV.
The ENC on-board unit (ENC OBU) for the toll networks of the Croatian motorway operators HAC and ARZ, which account for approximately 89% of the whole Croatian motorway network, can be obtained through DKV Euro Service.
This OBU can be used to pay the toll charges for vehicles in categories I, II, III and IV cash-free.
