To rent a car in Iceland, you need a valid driver's license, a card in the main driver's name, and to meet the minimum age requirement, which is typically 20 but can be 23 for certain vehicle categories. Your regular driver's license from your home country is valid for up to one year if it's in Roman script. If it's not in Roman script, an International Driving Permit (IDP) is required alongside your original license.
The most critical, and often overlooked, aspect is securing the right insurance. While basic Collision Damage Waiver (CDW) is included, Iceland's unique driving conditions make additional coverage essential.
Essential Documents & Requirements:
| Requirement | Details | Why It's Important |
|---|---|---|
| Valid Driver's License | Must be held for at least one year. Non-Roman script licenses need an IDP. | Legal requirement for driving. Police will check this during any traffic stop. |
| Credit Card | In the main driver's name. Debit cards or pre-paid cards are almost never accepted. | Used for the security deposit hold (block) during the rental period. |
| Minimum Age | Typically 20 years old for standard cars; 23 for 4x4s or premium vehicles. | Younger drivers face high young driver surcharges or may be ineligible to rent. |
| Passport | Required as a form of ID during pickup. | Verifies your identity and legal entry into the country. |
Beyond the paperwork, your choice of vehicle and insurance is paramount. For travel outside Reykjavik, especially on gravel roads like those leading to major waterfalls or highland tracks (F-roads), a 4x4 vehicle is mandatory by law. Declining added insurance like Gravel Protection (GP) and Sand and Ash Insurance (SAAP) is a significant financial risk, as standard CDW does not cover damage from Iceland's pervasive gravel roads or volcanic sandstorms.
Be prepared for a thorough vehicle inspection at pickup. Document any existing scratches, dents, or interior issues with photos or video before you drive off the lot. This protects you from being charged for pre-existing damage upon return.

Don't overthink it, but don't skip the essentials. You need your regular driver's license (as long as it's in English), a card—not a debit card—with your name on it, and your passport. You gotta be at least 20. The real pro tip? Get the full gravel and sand insurance. The roads are rough, and the rental companies will charge you for every tiny chip. It’s worth the peace of mind.

The three non-negotiable items are a valid driver's license held for a minimum of one year, a major card issued in the primary driver's name, and a passport for identification. You must meet the age requirement, which is usually 20. I strongly advise carefully reviewing the insurance options offered at the counter. Standard coverage often excludes damage from gravel, which is extremely common on Icelandic roads outside the city.

When we went, the key was ahead. You need the basics: license, credit card, and you must be 20. But the real lesson was about the car itself. For a family trip, even if you're sticking to the Ring Road, spring for a 4x4 for the extra space and stability. And absolutely, without a doubt, add the gravel protection insurance. We saw so many cars with cracked windshields. It’s better to pay a little extra upfront than a huge bill later.

Focus on the card and insurance. The rental agreement is secured by a credit card in the driver's name; debit cards are not accepted for the deposit hold. Then, critically assess your insurance. Basic CDW has a high liability amount. I opted for full coverage, including Gravel Protection and Sand and Ash Insurance. This decision saved me from stress when driving on gravel roads to iconic sites like Diamond Beach, where flying stones are a real hazard.
