Renting a car in Iceland, and what the insurance skips

Icelandic rentals include a collision damage waiver, and the counter will offer a Super CDW that cuts your deductible toward zero. The important thing to understand is what the upgrade does and does not do: it reduces what you pay on a covered claim, but it carries the same exclusions as the basic waiver. Paying more does not broaden the list.

The excluded list is the problem, because it is essentially a description of Iceland. Gravel and stone chips, windscreen and window glass, tires, and damage from blown sand and volcanic ash all sit outside standard CDW and Super CDW at most Icelandic companies. Roughly 30% of the road network is unpaved, and even the paved Ring Road has gravel patches and construction stretches where a passing truck can pepper your front end.

The numbers make it concrete. A windscreen crack is commonly 70,000 to 200,000 ISK to fix or replace, about $575 to $1,600. Gravel paint damage runs roughly 37,000 to 122,000 ISK, about $300 to $1,000. Sand and ash damage to paint, glass and lights, if you are caught in it without cover, can exceed 1,000,000 ISK.

Gravel Protection is the one most people should take, and it is usually the cheaper of the two at roughly $5 to $15 a day, though some companies price it nearer $29 bundled with wind cover. It handles the stone chips and glass damage that are the single most common surprise charge on an Icelandic rental. Some operators now include it by default, so check before you buy it twice.

Sand and Ash Protection (SAAP) is more seasonal and more specific. Strong winds lift loose sand and volcanic ash off dry ground and sandblast paint, glass, lights and trim. The worst window is February through April, when the snow has thawed but vegetation has not grown back to hold the sand down, and the exposed areas are mainly along the South Coast and in the Northeast. Expect around $13 to $15 a day. With it, your exposure typically drops to a fixed deductible in the region of 90,000 ISK; without it, you are liable for the lot.

Naming is inconsistent and worth reading carefully: some companies fold gravel into a product they call SAAP, others sell wind and gravel together, others separate all three. Rather than matching the label, ask which of gravel, glass, tires, sand and ash each line item actually covers, and what the deductible is on each.

F-roads are the mountain and highland tracks. They require a genuine 4x4, they are open only in summer, and taking a 2WD onto an F-road is illegal in Iceland. Do it and any damage is entirely yours, regardless of what you bought at the counter. Even in a 4x4, check whether your specific rental agreement permits F-roads at all, because some contracts and some third-party excess policies exclude them.

River crossings are the absolute. Many F-roads include unbridged fords, and no insurance sold in Iceland covers water damage to the engine or underbody. Not CDW, not Super CDW, not the add-ons, not a standalone excess policy. An engine flooded at a crossing is a bill you own outright, and it is a large one. If a ford looks deep, that is the end of the drive.

Two smaller ones worth knowing. Iceland's wind is strong enough to tear a car door off its hinges when you open it, which is a real and frequent claim, so open doors holding the handle and pointing into the wind. And single-vehicle damage and underbody strikes are treated separately by many policies, which is another reason to read the deductible list rather than the product name.

The counterintuitive advice is to prioritise breadth over deductible. A Super CDW that lowers your excess but still excludes glass and gravel is worse value in Iceland than basic cover plus the gravel add-on. Work out what each option covers, then decide, and remember that a standalone excess policy bought before you travel often covers glass, tires and underbody that the counter's waiver will not.

Budget the vehicle honestly. A small 2WD runs roughly $40 to $80 a day in shoulder and winter season, while a 4x4 in peak summer is more like $120 to $200 and up. If your route has no F-roads, you may not need the 4x4 at all; if it does, you are not choosing.

One newer cost people miss: since 1 January 2026 Iceland charges a per-kilometre road tax in place of much of the old fuel tax, and rental companies pass it on with a margin, so long-distance driving now carries a line item beyond fuel. The Iceland guide has the current rates, and the Iceland cash and cards guide covers paying for fuel on the road.

More on Iceland

The little money things nobody warns you about.

• Do I need cash in Iceland, or can I use cards?Short answer: barely any. Iceland is one of the most cashless countries on earth, and plenty of visitors complete a whole trip without touching a banknote. The money problem here is not payment, it is the prices.
• Tipping in IcelandThis is the easiest tipping page we write. Service is included, wages are decent, and nobody is waiting for a percentage. You can put your mental arithmetic away for the whole trip.
• Taxis in Iceland, and why there is no UberThere is no widespread Uber here, which surprises people. Taxis are licensed, metered, card-friendly and expensive, and the usual way to get one is to book it rather than wave at the street.
