What driving in Croatia is like
The Adriatic Highway (Jadranska magistrala, D8) hugging the coastline from Rijeka south toward Dubrovnik is the classic Croatian drive. For most visitors the real draw is the freedom to reach places trains and tours don't, on your own schedule, with the open road generally capped around 130 km/h motorways. Getting behind the wheel is the easy part: your International Driving Permit is a certified translation of your Japan licence, carried alongside it, so rental staff and officials in Croatia can read your credentials at a glance.

Local driving facts in Croatia
Emergency number: 112 (112 also connects from most mobiles). Typical maximum for cars on the fastest road class: 130 km/h motorways. Posted limits always take precedence.
- Tolls & road charges
- Croatia still uses a ticket-based toll system on most motorways (A1/A3/A5/A6 etc.), not a vignette: take a ticket on entry and pay on exit by cash (euros) or card; an ENC electronic tag gives a discount. Costs vary by distance, e.g. roughly EUR 30+ for Zagreb to Split.
- Parking
- Cities use colour-coded paid zones controlled mainly by SMS/app: in Zagreb Zone 1 is about EUR 1.60/hr (max 2 hrs), Zone 2 about EUR 0.70/hr (max 3 hrs), with cheaper outer zones. Coastal towns get extremely congested in summer; illegal parking risks towing.
- Penalties & enforcement
- Foreign drivers face on-the-spot fines from about EUR 70 for moderate speeding up to roughly EUR 2,000 for extreme speeding; the alcohol limit is 0.5 g/l (0.0 for drivers under 25). Speed cameras typically tolerate only about 10 km/h over, and rental firms pass camera fines to the renter with an admin fee.
- If you have an accident
- Call 112 (or police 192) and report any accident involving injury or significant damage; for minor damage-only crashes, move vehicles clear and complete a European Accident Statement form. Leaving the scene of an injury accident is a serious offence.
- City driving
- Zagreb's compact Upper Town (Gornji Grad) and the area around Ban Jelacic square have narrow one-way streets, trams sharing the carriageway, and tight paid parking zones - most visitors park in a garage and walk.
- Winter driving
- Winter equipment is mandatory on designated winter road sections from 15 November to 15 April regardless of actual snow: winter (M+S or 3PMSF) tyres on all wheels, or summer tyres with at least 4 mm tread plus chains carried. Driving without it risks an on-the-spot fine around EUR 130.
- Fuel
- Stations sell Eurosuper 95/100 petrol and Eurodizel diesel, mostly attended (self-serve growing); cards are widely accepted. Prices run roughly EUR 1.40-1.55 per litre, with rural and island stations sparser, so refuel before long stretches.
