Renting a car in Iceland: what you actually need
By Stefán · Iceland Roads · Backed by live Vegagerðin data, updated every 15 minutes
Do you need a 4x4? (the honest answer)
Most visitors do not. If your trip is the Ring Road, the Golden Circle, the South Coast, Snæfellsnes, or any paved route between towns, a normal two-wheel-drive car is enough from roughly May through October. The Ring Road is paved the whole way around and maintained year-round.
You DO need a 4x4 if any of these apply:
- You want to drive any F-road. Highland mountain roads legally require a 4x4. This is not a suggestion: insurance is void and fines apply if you take a 2WD onto an F-road, and rental companies track their cars by GPS. 34 of 42 F-roads are drivable right now.
- You're visiting between November and April and plan to drive beyond Reykjavík and the Golden Circle. A 4x4 doesn't repeal physics on ice, but the extra clearance and stability matter in snow, and winter tyres come standard on every rental in season (studded tyres are legal 1 November to 15 April).
- Landmannalaugar, Þórsmörk, Askja or Kerlingarfjöll are on your list. All are behind F-roads. Þórsmörk involves river crossings most rental contracts exclude entirely; take the bus or a super-jeep tour there.
| When | 2WD enough? | Notes |
|---|---|---|
| June to September, paved routes | Yes | The standard tourist case |
| June to September, highlands | No - 4x4 required | See when each F-road opens |
| October and April/May | Usually | Watch forecasts; late/early snow happens |
| November to March | 2WD works, 4x4 is more forgiving | Wind is the real danger, not drivetrain |
The insurance question (where the money actually goes)
Icelandic rentals are cheap to book and expensive to damage. The excess (deductible) on a basic rental is often 250,000 to 350,000 ISK. What the add-ons actually cover:
- CDW - included in practice; sets the base excess.
- SCDW (super CDW) - lowers the excess to a sane number. Usually worth it.
- Gravel protection (GP) - covers chips from flying gravel (paint, windshield, headlights - not the interior). Iceland-specific and genuinely useful: gravel damage is the most common claim here.
- Sand and ash protection (SAAP) - covers paint sandblasting in south-coast storms. Sounds exotic; the storms are real (Vík and the sandur plains). Cheap enough to take for shoulder-season south-coast drives.
- What standard packages never cover- water damage from river crossings, driving on closed roads, wind-caught doors in many contracts, and undercarriage damage in some. Wind-caught doors are the most common “wait, that's not covered?” claim in Iceland.
- The exception worth knowing- a few local companies sell a top-tier waiver that goes further: Blue Car Rental's Liability Waiver, for example, brings the excess to zero and, unusually, includes river-crossing water damage, wind-caught doors and underside damage (as of mid-2026 - always read the current terms). Gross negligence still voids it.
What about my credit card's rental insurance?
Premium cards do offer rental CDW and it can work in Iceland, with caveats: you usually must decline the rental company's own waivers (putting the full excess on you until the card reimburses you later - you pay first, claim afterwards), and card policies typically mirror the local exclusions: gravel, ash, water, wind doors, underbody, and often anything on an F-road or unsealed surface. Some exclude 4x4s entirely. The Iceland-specific damage types are exactly the ones cards don't cover. Reasonable use: a backstop for ordinary collision damage on a paved summer trip. Not a substitute for gravel protection, never for highlands.
The kilometer tax (new in 2026)
Since 1 January 2026 Iceland charges a per-kilometer road tax (kílómetragjald) on all cars: 6.95 ISK per km for normal passenger cars and SUVs, replacing the old fuel taxes (pump prices dropped roughly 80-105 ISK per liter in exchange). Rentals handle the reporting and pass the cost on - per actual km or as a flat daily fee - so compare how each company charges it. Driving the full Ring Road (1,332 km) adds about 9,300 ISK.
Tyres: what's legal, and whose problem it is
Minimum tread depth is 3.0 mm in the winter-tyre period (1 November to 14 April) and 1.6 mm the rest of the year; studded tyres are allowed 1 November to 15 April. The rental company is responsible for handing you a road-legal car, but the driver answers for the vehicle's condition at a roadside check. Thirty seconds at pickup checking tread and photographing the tyres with the rest of your walk-around protects you twice.
Local vs. international, and who's at Keflavík
Local Icelandic companies generally include more insurance in the headline price, keep newer winter tyres, and are used to explaining F-road rules. International brands can be cheaper on the sticker but stricter on excess and add-ons. Compare the price WITH SCDW and gravel protection, not the naked rate; the gap usually shrinks or flips.
At Keflavík airport a couple of international desks (Hertz, Sixt) operate at or in the terminal, and nearly everyone else - big brands and Icelandic companies alike - sits within about five minutes by free shuttle. The shuttle costs you ten minutes, not an hour; don't overweight “on-site” in the decision.
Five mistakes that cost real money
The Gullfoss shortcut
Booking a 2WD in July, then deciding at Gullfoss that Kjölur “looks fine”. It's an F-road. The GPS tracker knows.
The wind-caught door
Ignoring the wind forecast when opening doors. Hold the door with both hands in gusts; repairs run into hundreds of thousands of ISK.
The river detour
Crossing a river to save a detour. No standard insurance covers water.
The gravel transition
Speeding onto gravel. The paved-to-gravel edge is where tourists roll cars. Slow to 60-70 before the surface changes.
The Keflavík fuel fee
Returning the car un-fueled at airport prices plus a service fee. Fill up in Njarðvík first - the cheapest petrol in the country is 180 ISK/l right now. Compare fuel prices →
Common questions
Can I drive a rental car on F-roads in Iceland?
Only a 4x4 rented with F-road use allowed in the contract, only on F-roads that are currently open, and river crossings remain your own risk - no standard insurance covers water damage.
Is a 4x4 required by law in winter in Iceland?
No. Winter tyres are required (1 November to 14 April); the drivetrain is your choice. In practice a 4x4 is more forgiving outside the capital area in snow.
How much does a rental car cost in Iceland?
Rough 2026 numbers: a small 2WD from about 7,000-9,000 ISK per day in summer, a compact 4x4 from about 15,000, and a proper highland-capable 4x4 from 25,000 and up. Winter runs 30-50% cheaper outside the holidays.
Do I need an international driving permit for Iceland?
Not if your license is in Latin script (EU/EEA, UK, US, Canada and most others). Licenses in non-Latin scripts need an International Driving Permit alongside the original.
What is the Iceland kilometer tax on rental cars?
Since 1 January 2026 Iceland charges 6.95 ISK per kilometer for passenger cars, replacing the old fuel taxes. Rental companies pass it on per kilometer driven or as a flat daily fee - the full Ring Road adds roughly 9,300 ISK.
