Driving in Belgium with an Arizona Driving Licence: IDP Requirements and Rules
A visitor aged 18 or over can drive an ordinary car in Belgium with a valid Arizona licence. A separate International Driving Permit (IDP) is not legally required for that recognised licence, although U.S. guidance recommends one and some rental companies require it. No separate visitor translation is specified. Belgium does not state a fixed tourist driving-day limit, but registration as a resident changes the rules.
Quick answer
For a short visit, the main practical distinction is between permission to drive and what the rental counter will accept. Enterprise requires an IDP for non-EU licence holders, while Hertz Brussels Airport recommends one.
How Belgium treats an Arizona licence
Arizona is a U.S. state licensing jurisdiction, not a separate treaty party. Belgium's federal guidance accepts recognised non-European national licences for visitors, and the U.S. Department of State expressly confirms that adults with valid U.S. licences may drive during a tourist or short visit. Arizona's ordinary operator licence is Class D.
Belgium's published United States annex lists Arizona Class D as corresponding to Belgian category B for licence exchange. It also lists A to B, BE, C1, C1E, C and CE, B to B, BE, C1 and C, and C to B. These are administrative exchange equivalences, not permission to drive every listed vehicle on a short trip.
International Driving Permit: law, advice and model
Belgium's licence rules allow a non-resident to use a recognised national foreign licence without adding an IDP. U.S. government travel advice nevertheless recommends obtaining one before driving abroad, and AAA describes it as a translation that supplements the state licence. This is a recommendation, not an extra Belgian legal condition for a valid Arizona licence.
For an Arizona-issued licence, the authorised U.S. IDP is the 1949 Geneva Convention model, available from AAA or the American Automobile Touring Alliance (AATA). It is valid for one year subject to the underlying licence's validity. Belgium also uses the 1968 Vienna Convention for Belgian-issued IDPs, but that does not change the model issued by the United States.
Visitor driving and becoming resident
For a tourist or short-term visitor, official U.S. guidance permits an adult with a valid U.S. licence to drive. The verified Belgian rule sets no universal fixed maximum measured from tourist arrival, so the 185-day figure must not be presented as a 185-day tourist allowance.
For someone registered in Belgium, the federal rule permits driving on a recognised non-EU licence during the first 185 days of registration. After that threshold, ordinary residents need a Belgian or European licence. An exchange application may start earlier, but a Belgian replacement is normally issued only after the registration threshold, provided the original licence model and other conditions qualify. A Belgian municipality may request a sworn translation during exchange.
Renting a car with an Arizona licence
Enterprise's published Belgium guide requires a valid licence, a passport, a major credit card in the renter's name and an IDP from anyone holding a non-EU licence. It also sets a minimum rental age of 21. Hertz's Brussels Airport page instead requires a valid national licence held for at least one year and says an IDP is highly recommended for non-EU renters. Hertz does not accept a digital licence there.

Roadside documents and insurance
Belgian Federal Police guidance calls for original driving and vehicle documents at checks. Carry the physical Arizona licence and make sure the vehicle has its registration and insurance certificate. Inspection documentation is also relevant when applicable. An IDP, if carried, does not replace the national licence.
Belgium requires motor vehicles in traffic to have at least third-party liability insurance and an insurance certificate in the vehicle. This does not establish that an Arizona auto policy covers Belgium. If renting, review the insurer and rental contract for applicable liability and damage protection.
Exceptions relevant to Arizona drivers
An Arizona graduated Class G licence is issued to drivers under 18, whereas the State Department's Belgium visitor guidance expressly covers drivers aged 18 or older. The Belgian Arizona exchange table assigns no exchange category to Class G or motorcycle Class M. That absence is an exchange limitation, not proof that a visitor's motorcycle authorisation is invalid. Ask the Belgian licensing authority about motorcycle and commercial categories before driving those vehicles.

Practical recommendation
For a short trip in a standard rental car, bring the original Arizona Class D licence and get a genuine U.S. IDP if your selected renter asks for it. The 1949 Geneva-model permit is the appropriate U.S.-issued document. Before a permanent move, ask your Belgian municipality to check the exact Arizona licence and exchange requirements rather than relying on visitor rules.
