Driving in Greece with an Idaho Driving Licence: IDP Requirements and Rules
Greece's Road Traffic Code recognises a valid U.S.-issued driving licence, including an Idaho licence, for mopeds, motorcycles, motor tricycles, quadricycles and passenger cars during the holder's stay, provided the licence covers the vehicle and Greek minimum-age rules are met. An International Driving Permit (IDP) and a separate translation are not required by that U.S.-specific rule. Some rental companies and insurers can impose stricter documentation requirements.
Quick answer
For ordinary visitor driving in a passenger car, a valid Idaho licence is directly recognised by the Greek U.S.-licence provision. The legal answer and the rental answer are not identical: Greek law does not make an IDP mandatory for this licence, but some rental companies do. AAA also recommends IDPs for overseas driving, so an IDP can still be useful even though it is not the legal basis for recognition.
How Greek law treats an Idaho licence
Article 98(3)(η) of Greece's Road Traffic Code, Law 5209/2025, expressly covers valid driving licences issued by the United States. Idaho is a U.S. licensing jurisdiction, so an Idaho licence falls within that country-level rule. The clause covers mopeds, motorcycles, motor tricycles, quadricycles and passenger cars during the holder's stay in Greece. Article 98 also requires the appropriate licence category and the Greek minimum age for that category.
For an ordinary Idaho Class D holder, the relevant covered use is a passenger car. Motorcycle use requires an Idaho credential carrying the appropriate motorcycle entitlement. The U.S.-specific clause does not expressly establish visitor recognition for commercial truck or bus privileges, so an Idaho commercial driving licence should not be assumed to carry those privileges in Greece.
IDP requirement, recommendation and model
An IDP is not legally required for the vehicle categories covered by article 98(3)(η) when the driver holds a valid Idaho licence. The U.S.-specific clause also has no separate translation condition. This is different from nearby provisions in article 98 that expressly impose translation conditions on other licence groups.
If an IDP is obtained for rental, insurance or practical use, the U.S. permit is issued under the 1949 Geneva Convention framework. The U.S. Department of State identifies AAA and AATA as the authorized U.S. issuers, and AAA explains that the permit supplements rather than replaces the valid U.S. licence. AAA recommends obtaining an IDP for overseas driving. That recommendation is not a Greek legal requirement.
Visitor stays and becoming resident
The current Greek code describes the U.S.-licence permission as applying during the holder's stay and does not state a numeric day limit in article 98(3)(η). U.S. Department of State Greece guidance says a Greek licence is required if a person stays more than 185 days. Greece's National Registry of Administrative Public Services also maintains a procedure for converting a valid U.S. licence after acquisition of usual residence and uses residence documentation tied to a 185-day period. Because these sources frame the time condition differently, this record does not convert 185 days into an unqualified statutory visitor maximum.
A person becoming usually resident should use the Greek conversion procedure rather than assuming the visitor rule continues indefinitely. The resident-conversion procedure has its own documentation requirements, including a translation of the foreign licence. That conversion requirement is separate from the no-translation position for visitor driving under article 98(3)(η).
Rental-car requirements
Rental companies can set document rules that are stricter than the legal minimum for driving. The companies checked do not publish one uniform rule.

| SIXT Greece | A valid licence is required and its Greece terms say a licence from outside the EU must be complemented by an international driving licence. Its Greece rental page tells customers to bring a valid licence and IDP. | First-party SIXT Greece pages checked 2026-09-28 |
| Avis Greece | Avis states that the driver must present a licence held for at least one year and ID or passport. Its FAQ says the licence must be EU-issued or the driver must hold an IDP, which must be accompanied by the national licence. | Avis Greece FAQ checked 2026-09-28 |
| Hertz Greece | Hertz's country-specific licence table lists the United States as accepted with a national driving licence. A broader Hertz page uses stricter wording for non-EU licences, so the booking-specific requirement should be confirmed. | Hertz Greece pages checked 2026-09-28 |
Documents to carry and insurance
Article 103 of the Greek Road Traffic Code requires a driver to carry the lawful driving licence. It also lists vehicle registration, proof of insurance and road-tax documentation. For rental and leasing vehicles, article 103 specifically allows a copy of the registration document and removes the requirement to carry proof of insurance and the road-tax receipt in the vehicle.
Coverage rules are separate. The U.S. Department of State warns that insurance companies may require both a valid U.S. licence and an IDP for coverage in Greece. SIXT's published terms also link rental protections to the driver possessing the required driving licence. Check the applicable insurance or rental contract rather than treating legal recognition of the Idaho licence as proof that every policy condition is satisfied.
Important limits and exceptions
The direct U.S.-licence recognition rule is limited to the vehicle types it names and remains subject to appropriate-category and minimum-age requirements. It should not be stretched to cover Idaho commercial truck or bus privileges without separate authority. Rental-company document rules can also be stricter than Greek law, and resident conversion has documentation requirements that do not apply to the same short-term visitor situation.

Practical recommendation
For a short visit in a passenger car, carry the valid physical Idaho licence that covers the vehicle. Greek law does not require an IDP or a separate translation under the U.S.-specific recognition rule, but obtain the 1949 Geneva Convention IDP before travel if the chosen rental company or insurer requires it. Confirm the rental terms before paying. If the stay is approaching 185 days or you become usually resident, confirm the conversion timing with the competent Greek Regional Unit transport authority.
