Croatia's coastline is one of Europe's most spectacular driving corridors. From the Istrian peninsula in the north to the walled city of Dubrovnik in the far south, more than 1,700 kilometres of mainland coast and over a thousand islands create a road trip playground. But there are quirks to driving in Croatia that catch visitors off guard: the motorway toll system, the Bosnia-Herzegovina corridor that splits the country in two, and the sheer volume of summer traffic on the coastal road. Here is everything you need to know.
Documents, Licences & Legal Requirements
EU driving licences are accepted without restriction. UK licence holders do not currently need an IDP for short visits, though carrying one is advisable. 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 (must be accessible inside the cabin, not in the boot)
- 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 the Sveti Rok tunnel (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 approximately 190 HRK (about 25 EUR). Payment is accepted in euros (Croatia adopted the euro in January 2023), by credit card, or via the ENC electronic toll system.
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 alternative coastal road (E65) is far more scenic but takes 7 to 8 hours. 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.
However, if you are exploring the coast slowly and want to visit Ston (famous for its oysters and medieval walls), the Peljesac route adds the bridge naturally to your journey. 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 / E65) 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 brutally 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 new 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, Pasman, and Dugi Otok; and from Dubrovnik to Mljet and the Elaphiti islands.
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 costs range from 150 to 400 HRK (20 to 53 EUR) 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 just 30 minutes' drive from the port.
Fuel, Speed Limits & Practical Information
Fuel prices in Croatia are moderate by European standards. Unleaded 95 costs approximately 1.50 to 1.70 EUR per litre, and diesel is similar. 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 under 25. Fines are issued on the spot and range from 65 EUR for minor speeding to over 1,300 EUR 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 (Dubrovnik currently charges around 6 to 10 EUR per hour near the old town). In Split, the Spaladium Arena car park offers affordable all-day parking with a bus connection to the centre.

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 hidden 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.
