Croatia car rental guide
Driving Rules and Speed Limits in Croatia
The headline rules are standard for the region, but two details catch visitors out: the stricter alcohol limit for younger and newly-licensed drivers, and a legal requirement most rental cars already meet but rarely get mentioned — a spare bulb kit.
Speed limits at a glance
| Road type | Limit |
|---|---|
| Built-up areas | 50 km/h |
| Outside built-up areas | 90 km/h |
| Expressways | 110 km/h |
| Motorways | 130 km/h |
Drivers under 25 must stay 10 km/h below these limits — 80 km/h on open roads, 100 km/h on expressways, 120 km/h on motorways — a rule that surprises younger renters who assume the standard limits apply to them.
Alcohol: the limit depends on who's driving
The standard limit is 0.5 g/l, but it drops to zero for drivers under 24, anyone who has held a licence for less than two years, and all professional drivers. If either applies to you, the safest plan is not drinking at all before driving.
Headlights and the spare bulb rule
Dipped headlights are required during the low-visibility months, roughly late October to late March, and some guidance treats it as a year-round rule — leaving them on regardless is the safer default. Croatia also still legally requires a spare bulb kit in the car; most rental vehicles already carry one, but it's worth confirming rather than assuming.
Where the roads get demanding
The coastal road connecting Istria to the rest of the Adriatic coast narrows and curves through towns in peak season, when traffic volume genuinely slows things down. Inland routes toward the interior are calmer but can be less well-lit at night, so plan arrival times with some margin.
