What you need to drive legally in Iceland

You can drive in Iceland with your valid U.S. driver's license alone for up to three months. You do not need an International Driving Permit (IDP) to rent a car or drive on Icelandic roads if your U.S. license is current and written in English. However, carrying an IDP alongside your U.S. license removes any ambiguity with police or rental companies and is inexpensive to obtain before you leave.

The IDP is not a separate license — it is a translation document that explains your U.S. license to authorities who may not read English fluently. Icelandic police recognize U.S. licenses directly, but some rental car companies prefer the IDP as proof that you have read and understood local traffic rules. Having both documents in your wallet takes the guesswork out of a roadside stop.

Key Takeaways

  • Your valid U.S. driver's license is sufficient to drive in Iceland for stays up to three months without an International Driving Permit.
  • An International Driving Permit is a translation document issued by the American Automobile Association (AAA) and costs $20, with a passport photo required.
  • You must be at least 20 years old to rent a car in Iceland, and some rental companies charge extra for drivers under 25.
  • Icelandic traffic rules differ from U.S. standards — headlights must be on at all times, and speed limits are strictly enforced with heavy fines.
  • If you stay longer than three months, you must convert your U.S. license to an Icelandic one through the Icelandic Road and Coastal Administration.

How to get an International Driving Permit from AAA

The American Automobile Association (AAA) is the only organization in the United States authorized to issue International Driving Permits. You can obtain one in person at any AAA office or by mail. The permit costs $20 and is valid for one year from the date of issue.

To explore in person, bring your valid U.S. driver's license, a passport-sized photo (2 by 2 inches), and $20 cash or card. The AAA office will complete the process on the spot and hand you the permit when ready. If you explore by mail, read the process form from the AAA website, include a passport photo, a photocopy of your license, and a check or money order, then mail the packet to your nearest AAA office. Processing by mail typically takes one to two weeks.

The IDP is printed in multiple languages and fits in your wallet. It does not replace your U.S. license — you must carry both documents together. The permit is not required by Icelandic law but is recognized by rental companies and provides a safeguard if a police officer questions whether you understand local traffic rules.

Age requirements and rental car restrictions in Iceland

You must be at least 20 years old to rent a car in Iceland. Most rental companies allow drivers aged 20 to 24 but charge a young driver surcharge, typically $15 to $25 per day. Drivers 25 and older pay standard rates with no additional fee.

Some rental companies set their minimum age at 21 or 23, so confirm the policy when you book. If you are under 25, you may also face restrictions on vehicle type — some companies do not rent four-wheel-drive vehicles or larger SUVs to younger drivers. Check the rental agreement carefully, as these policies vary by company and can affect your ability to drive on unpaved roads in the highlands.

Icelandic traffic rules that differ from U.S. standards

Iceland enforces several traffic rules that are stricter or different from those in most U.S. states. Headlights must be on at all times, even during daylight hours — this is a legal requirement, not a recommendation. Speed limits are enforced with automated cameras and heavy fines; speeding tickets start at around 10,000 Icelandic króna (roughly $75 USD) and increase sharply for higher speeds.

Seatbelts are mandatory for all passengers, and children under six must sit in a car seat. Drink-driving laws are strict — the legal blood alcohol limit is 0.04 percent, lower than the 0.08 percent standard in most U.S. states. Fines for driving under the influence begin at 50,000 króna and can include license suspension or jail time.

Road conditions in Iceland change rapidly, especially in winter and in the highlands. Many roads are unpaved gravel, and some are closed seasonally. Check the Icelandic Road and Coastal Administration website before you drive to confirm road status. Driving off marked roads is illegal and can result in fines and damage charges from your rental company.

What to do if you plan to stay longer than three months

If you will be in Iceland for more than three months, you must convert your U.S. driver's license to an Icelandic one. You cannot continue to drive on your U.S. license after the three-month mark. Contact the Icelandic Road and Coastal Administration (Samgöngustofa) to begin the conversion process.

The conversion requires your U.S. license, a valid passport, proof of residency in Iceland (such as a rental agreement or utility bill), and a medical certificate if you are over 70 years old. You will also need to pass an eye test at an Icelandic optometrist. The process takes several weeks, so start it well before your three-month mark expires.

Insurance and liability when driving in Iceland

All rental cars in Iceland come with mandatory third-party liability insurance, which covers damage you cause to other vehicles or property. This insurance is included in your rental rate and is required by law. However, it does not cover damage to the rental car itself.

You can purchase a collision damage waiver (CDW) or super collision damage waiver (SCDW) from the rental company to cover damage to your vehicle. These are optional but strongly recommended, as repair costs in Iceland are high and gravel roads cause frequent damage. Read the rental agreement to understand what is and is not covered — some policies exclude damage to the windshield, undercarriage, or tires, which are common on Icelandic roads.

Documents to carry while driving in Iceland

Keep your U.S. driver's license and International Driving Permit (if you have one) in your wallet at all times while driving. You should also carry your rental car agreement, proof of insurance, and your passport. Icelandic police may ask to see any of these documents during a traffic stop.

If you are renting a car, the rental company will provide a document showing the vehicle registration and insurance details. Keep this in the car. You are also required to carry a reflective safety vest, a warning triangle, and a headlight bulb kit — most rental cars include these, but confirm before you leave the lot. If you are stopped without these items, you can be fined.

Frequently Asked Questions

Do I need an International Driving Permit to rent a car in Iceland?

No, you do not need one. Your U.S. driver's license is sufficient. However, some rental companies prefer to see an IDP alongside your U.S. license as proof you understand local traffic rules. It costs $20 and takes one to two weeks to obtain by mail, so it is worth getting if you want to avoid any questions at the rental counter.

What happens if I get pulled over by Icelandic police without an International Driving Permit?

You will not be breaking the law. Your U.S. license is valid in Iceland for three months. A police officer may ask questions if they cannot read English fluently, but they will recognize your license as legitimate. Having an IDP avoids this conversation entirely, but it is not required.

Can I drive in Iceland's highlands and F-roads with a regular rental car?

No. Highlands roads (F-roads) require a four-wheel-drive vehicle with high clearance. Regular sedans and two-wheel-drive SUVs are not permitted on these roads, and rental companies will charge you heavily if you damage the car by driving it where it should not go. Book a four-wheel-drive rental if you plan to explore the highlands.

What is the speed limit in Iceland, and how are speeding tickets enforced?

Speed limits are 50 kilometers per hour (31 mph) in towns, 80 kph (50 mph) on rural paved roads, and 80 kph on unpaved roads. Limits are enforced with automated cameras and handheld radar. Speeding fines start around 10,000 króna and increase with the amount you exceed the limit. Rental companies may also charge you an administrative fee if they receive a speeding ticket in your name.

What should I do if my U.S. license is expired or suspended?

You cannot drive in Iceland on an expired or suspended license. Your license must be valid and current. If your license is suspended in the U.S., you are not permitted to drive in Iceland, even though Iceland does not have access to U.S. driving records. Rental companies will not rent to you without a valid license, and driving without one is a criminal offense in Iceland.
