The motorway system in Croatia has greatly improved in recent years thanks to some rather extensive road building. There is (amongst other routes) now motorways linking Zagreb to Pula, Rijeka, Zadar and Split along the coast and Varazdin in the interior. Further works have commenced to eventually allow for a full coastal motorway all the way down to Durbrovnik.
In Croatia, traffic drives on the right. The last decade has seen considerable investment in Croatia's roads and the country has an extensive network of highways (designated as E roads) and unclassified roads. Motorway connections are continually improving, and Croatia's 11 motorways are designated with the numbers A1 to A11. The A1 is the main artery between Zagreb and Split; sometime after 2008 it will extend beyond Dubrovnik. Roads are generally sealed and in good condition. A toll is payable on motorways.
The minimum driving age is 18. Speed limits are 130 kph (81 mph) on motorways, 110 kph (62 mph) on highways, 50 kph (31 mph) in built-up areas and 90 kph (50 mph) outside built-up areas. Heavy fines are imposed for speeding. It is compulsory for front and rear passengers to wear seat belts. It is illegal to use a hand-held mobile telephone while driving and to overtake military convoys or long lines of traffic behind slow moving vehicles.
Croatian law requires that all motor vehicles drive with dipped headlights on at all times. You may be fined if you are driving without your headlights on, even during the daylight hours.
Drivers holding their licences for less than two years are prohibited from driving cars with more-powerful-than-average engines. Regardless of their age, such drivers will be allowed to drive after 11 pm only in the presence of a person older than 25 who has had a clean driving record for more than two years.
Under Croatian law, a driver who commits two serious offences over a period of two years could face a 60-day jail term.
UK driving licence is valid for up to six months from entry into Croatia. For other nationals, national or International Driving Permit is required. If you are staying longer, you need to apply for a Croatian licence.
All non-Croat motorists should also carry a valid passport or national identity card as proof of identity at all times. A Green Card should be carried by visitors (except EU nationals) taking their own car into Croatia. National registration in country of origin is required for all foreign vehicles. Third party insurance is mandatory when hiring a car and a valid credit card is also needed.
