Iceland is one of the great road trip destinations in the world. Wide open roads, dramatic scenery, and relatively light traffic make it a genuine pleasure to drive. But Iceland also has some specific road rules — and some fines — that catch visitors off guard. Get these wrong and you’re looking at significant penalties that can put a dent in your holiday budget.
Here’s a straightforward guide to everything you need to know before you drive.
Speed Limits
Iceland’s speed limits are clearly signed and strictly enforced.
| Road type | Speed limit |
|---|---|
| Built-up areas (towns and villages) | 50 km/h |
| Unpaved / gravel roads | 80 km/h |
| Paved roads outside built-up areas | 90 km/h |
The 80 km/h limit on gravel roads catches a lot of visitors out — many assume it’s 90 km/h everywhere outside towns. It’s not. If you’re on a gravel surface, the limit drops to 80.
Speed cameras are common on Icelandic roads, including fixed cameras and mobile units. Fines for speeding start at around ISK 15,000–20,000 for minor exceedances and rise steeply for anything more serious. Rental companies will pass the fine on to you.
Headlights On at All Times
In Iceland, headlights must be switched on at all times — day or night, summer or winter. This is the law, not a recommendation. Modern rental cars typically have automatic lights and daytime running lights that satisfy this requirement, but it’s worth confirming your car’s settings before you set off.
Seatbelts
All occupants in the vehicle must wear a seatbelt at all times. This applies to every seat in the car. Fines for non-compliance apply to both the driver and the passenger.
Mobile Phones and Hands-Free
Using a handheld mobile phone while driving is illegal in Iceland. This includes texting, scrolling and holding the phone to your ear. Hands-free use (via Bluetooth or a mounted phone holder) is permitted, but you should avoid anything that takes your attention off the road. Fines are significant.
Drink Driving
Iceland’s blood alcohol limit is 0.05% BAC — lower than in many countries. In practice, this means even one or two drinks could put you over the limit depending on your body weight and what you’ve eaten. The recommendation is simple: if you’re driving, don’t drink. Icelandic enforcement is strict, and penalties include heavy fines, loss of licence and potentially criminal charges.
Driving Off-Road
This one carries some of the most serious fines in Iceland, and it’s important to understand what it means.
Driving off marked roads or tracks is illegal. This isn’t just a rule to protect the environment (though it does) — it’s a criminal offence with fines that can reach hundreds of thousands of ISK, or even higher for serious damage. Iceland’s highland vegetation, moss and lava soil are extremely fragile. Tyre tracks can leave scars visible for decades.
“Off-road” means any land that isn’t a designated road or track. That includes driving across open fields to get a better photo, parking on vegetation to avoid a muddy verge, or cutting across heath to shortcut a bend. Don’t do it. If you’re unsure whether somewhere is a legal track, it probably isn’t.
River Crossings and Closed Roads
Driving on a closed road is illegal and carries fines. F-roads and mountain tracks are closed in winter and sometimes during summer storms. The closure signs are clear. If a road is signed as closed, turn back — both for legal reasons and for your own safety.
For river crossings on F-roads, there’s no legal prohibition on attempting a crossing — but common sense applies. If conditions are unsafe, mountain rescue in Iceland operates on a voluntary basis, and a reckless crossing that requires rescue is not something to be proud of.
Other Rules Worth Knowing
Give way to the right — at unmarked intersections, the vehicle coming from the right has priority. This is the general rule in Iceland and across Scandinavia.
Single-lane bridges — Iceland has many single-lane bridges on the Ring Road. Slow down as you approach, check if a vehicle is already on the bridge, and if so, wait. The first vehicle to arrive generally has priority.
Blind hills — marked with a yellow warning sign (a hill shape with an exclamation mark). These indicate summits where visibility drops suddenly. Keep left and reduce speed.
Animals on the road — sheep, horses and occasionally reindeer in the east can appear on roads without warning, particularly on rural roads and open moorland. Especially at dawn, dusk and at night.
Parking — in Reykjavík, paid parking zones are marked and enforced. In the countryside, park in designated areas and never on vegetation.
