Croatia has more than 1,700 kilometres of mainland coast, from Istria in the north to Dubrovnik in the far south, and over a thousand islands. This guide covers documents, the motorway toll system, the Bosnian corridor at Neum and the Peljesac Bridge, the coast road, island car ferries, and speed, alcohol and parking rules. Expect very heavy traffic on the coast in July and August.
Documents, Licences & Legal Requirements
EU driving licences are accepted without restriction. UK photocard licence holders do not need an IDP (see using your UK licence abroad). Drivers from the US, Canada, Australia, and most other countries need an International Driving Permit alongside their national licence.
Croatia became an EU member in 2013 and joined the Schengen Area in January 2023, which eliminated border controls with Slovenia and Hungary. However, the Bosnia-Herzegovina border crossing on the coastal route (more on that below) remains a non-Schengen crossing with passport checks.
Mandatory equipment to carry in your vehicle:
- Warning triangle
- Reflective vest (keep it within reach in the cabin; you must wear it if you get out on the road)
- Spare bulb set (technically required, rarely checked)
- First-aid kit
Headlights must be on at all times from the last Sunday in October to the last Sunday in March. Outside this period, they are required only in poor visibility, but keeping them on permanently is good practice on the coastal road.
The Motorway System & Tolls
Croatia's motorway network is modern, well-maintained, and extensive for a country of its size. The main routes are:
- A1: Zagreb to Split (and continuing to Ploce). The main artery connecting the capital to the coast. Approximately 400 km with several long tunnels, including Mala Kapela (5.8 km) and Sveti Rok (5.7 km).
- A3: Bregana (Slovenian border) to Lipovac (Serbian border) via Zagreb. The main east-west corridor.
- A6: Zagreb to Rijeka. The main route to the northern Adriatic and Istria.
Tolls are collected at barriers using a ticket system. You take a ticket when entering the motorway and pay at exit. The A1 from Zagreb to Split costs roughly EUR 25-30 for a car. Payment is accepted in euros (Croatia adopted the euro in January 2023), by card, or via the ENC electronic toll system. Croatia is moving to barrier-free electronic tolling, so check how tolls are collected when you travel.
ENC Electronic Toll Device
If you are staying for more than a few days and plan to use the motorways frequently, the ENC (Elektronicka Naplata Cestarine) device saves time by allowing you to use dedicated fast lanes. You can pick one up at any HAC (Croatian Motorways) office, large petrol stations, or some rental agencies. A deposit is required and it works on a prepaid credit system.
The A1 from Zagreb to Split takes about 4 hours on the motorway. The coast road (the D8) is far more scenic but takes 7 to 8 hours; our Zagreb to Split drive has the motorway route. If time allows, drive one way on the motorway and the other on the coast.
The Bosnia-Herzegovina Corridor: Neum
This is the single most important thing to understand about driving Croatia's coast. A 20-kilometre strip of Bosnian coastline at the town of Neum splits Croatia in two, separating the main body of the country from the Dubrovnik region. Until recently, driving from Split to Dubrovnik meant crossing two international borders.
The Peljesac Bridge, opened in July 2022, now bypasses Neum entirely by connecting the mainland to the Peljesac Peninsula, which then connects to the Croatian mainland south of Neum. This means you can drive from Split to Dubrovnik without leaving Croatia.
If you want to visit Ston (known for its oysters and medieval walls), the Peljesac route takes you there anyway. The old route through Neum is still an option and is shorter in distance, though border queues in peak summer could add 30 to 90 minutes each way.
If You Do Cross Through Neum
- You need your passport (not just an ID card) for non-EU citizens.
- EU citizens can use national ID cards.
- The crossing is quick outside of July and August but can be painfully slow in peak season.
- Your rental car insurance should cover Bosnia-Herzegovina. Check with your rental company; most Croatian rentals include Bosnia but some budget companies charge extra or exclude it.
- If your rental does not cover Bosnia, you must use the Peljesac Bridge route.
Driving the Adriatic Coast
The Adriatic Highway (Jadranska magistrala, the D8) runs along almost the entire coastline from Rijeka to Dubrovnik. It is one of Europe's most scenic drives, hugging cliffsides above the sea, passing through historic towns, and offering views of hundreds of islands.
It is also narrow, winding and very busy in summer. Between Split and Dubrovnik, the road is often a single lane in each direction with limited overtaking opportunities. Caravans, tour buses, and slow-moving trucks are common. Expect average speeds of 40 to 60 km/h in July and August.
Recommended coastal driving segments:
- Rijeka to Zadar. The northern Adriatic coast, less crowded than the south. Stop at Senj and the Paklenica gorge.
- Zadar to Split via Sibenik. Pass through two beautiful cathedral cities. Detour to Krka National Park.
- Split to Dubrovnik via the Peljesac Peninsula. Cross the bridge, sample Ston's oysters, visit the vineyards of Dingac, then continue to Dubrovnik.
- Istrian peninsula loop. From Rijeka through Rovinj, Pula, Porec, and Motovun. Hilltop towns, Roman ruins, and truffle country.
Ferry Connections to the Islands
Jadrolinija is the state-owned ferry company and operates the majority of routes to Croatia's islands. Connections run from Split to Brac, Hvar, Vis, and Korcula; from Zadar to Ugljan and Dugi Otok, and from Biograd to Pasman; and from Dubrovnik to the Elaphiti islands, with car ferries to Mljet from Prapratno on the Peljesac Peninsula.
Taking a car on the ferry is essential for larger islands like Brac and Korcula but unnecessary for Hvar (where traffic is restricted in Hvar Town) and impractical for smaller islands. Vehicle reservations are strongly recommended in summer; foot passenger tickets rarely sell out.
- Car ferry fares are roughly EUR 20-60 for a car, depending on the route and vehicle size.
- Fast catamarans (foot passengers only) are faster alternatives on many routes.
- Private operators like Krilo and TP Line supplement Jadrolinija on popular routes.
The car ferry from Split to Supetar (Brac) runs almost hourly in summer and takes just 50 minutes. It is one of the easiest island excursions you can add to a Croatian road trip, with Zlatni Rat beach at Bol about 40 minutes' drive from the port.
Fuel, Speed Limits & Practical Information
Fuel prices in Croatia are moderate by European standards. Croatia caps fuel prices, and unleaded 95 and diesel are usually around EUR 1.50 per litre. Stations are plentiful on the motorways and coastal road, with INA and Petrol being the main chains. Credit cards are widely accepted.
Speed limits:
- Urban areas: 50 km/h
- Rural roads: 90 km/h
- Dual carriageways: 110 km/h
- Motorways: 130 km/h
The blood alcohol limit is 0.05%, and zero tolerance (0.00%) applies to drivers aged 24 and under. Fines are issued on the spot, from around EUR 60 for minor speeding to well over EUR 1,000 for serious offences. Croatian police are active on the coastal road, particularly in summer.
Parking in Dubrovnik is notoriously difficult and expensive. Use the large car parks on the approach to the old town; near the walls, expect EUR 6 or more per hour. In Split, the Spaladium Arena car park offers affordable all-day parking with a bus connection to the centre.
Plan this trip to map out a route from Zagreb to Dubrovnik.
Frequently asked questions
Do I still need to cross Bosnia to get to Dubrovnik?
No. Since the Peljesac Bridge opened in July 2022, you can drive from Split to Dubrovnik entirely within Croatia. The bridge is free to use and takes you via the Peljesac Peninsula. The old route through the Bosnian town of Neum is still available if you prefer a shorter distance, but the bridge route avoids all border crossings.
What currency do I need for tolls and fuel?
Croatia adopted the euro on 1 January 2023. All tolls, fuel stations, restaurants, and shops operate in euros. You no longer need Croatian kuna. Credit and debit cards are accepted almost everywhere, including at motorway toll booths and most parking meters in cities.
Is it worth renting a car or using buses along the coast?
Buses connect all major coastal cities efficiently and affordably. However, a car gives you access to small beaches, hilltop villages, national parks and islands that buses do not reach. If your trip is focused on just Split and Dubrovnik, buses are fine. If you want to explore Istria, the islands, or anywhere off the main highway, a car is strongly recommended. Rental prices start from around 30 to 45 EUR per day for a small car in summer.
