Does Alamo require an IDP in Croatia?

Alamo's standard minimum rental age in the US is 21 (18 in Michigan and New York where state law requires it); renters aged 21-24 pay a "young/youthful driver" surcharge that averages about $25 per day but varies by location (for example roughly $13/day in Michigan and $20/day in New York), and under-25 renters may be restricted to certain car classes.

A major credit card in the primary renter's name is required at most locations; debit/check cards bearing a Visa, Mastercard or Discover logo are accepted at airport locations only with a ticketed return travel itinerary (Discover not accepted in Canada), and the name/address on the card and license must match, with a hold placed at pickup that reduces available funds.

Additional authorized drivers typically cost about $15 per day each (around $5/day in New York), and every additional driver must also meet the minimum-age and license requirements; some promotions or contracted/corporate rates waive the fee. Alamo requires each driver to hold a valid, unexpired driver's license; the license must have been issued before the rental and held for the qualifying period, with locations commonly expecting it to have been held for at least 1 year.

Vehicles rented in the US may typically be driven throughout the US and Canada but cannot be taken into Mexico; vehicles rented in Canada may be driven in Canada and the US. Cross-border and one-way rentals must be disclosed and authorized at the counter, and one-way availability and drop fees vary by location.

Alamo states an International Driving Permit cannot be used on its own and the home-country license must always be presented; an IDP is recommended (not required) when the license uses Roman/English letters, but is required when the license is in a non-Roman alphabet (e.g. Russian, Japanese, Arabic), with a typed professional translation as a substitute if no IDP is available.

Croatia still uses a ticket-based toll system on most motorways (A1/A3/A5/A6 etc.), not a vignette: take a ticket on entry and pay on exit by cash (euros) or card; an ENC electronic tag gives a discount. Costs vary by distance, e.g. roughly EUR 30+ for Zagreb to Split.

Cities use colour-coded paid zones controlled mainly by SMS/app: in Zagreb Zone 1 is about EUR 1.60/hr (max 2 hrs), Zone 2 about EUR 0.70/hr (max 3 hrs), with cheaper outer zones. Coastal towns get extremely congested in summer; illegal parking risks towing.

Foreign drivers face on-the-spot fines from about EUR 70 for moderate speeding up to roughly EUR 2,000 for extreme speeding; the alcohol limit is 0.5 g/l (0.0 for drivers under 25). Speed cameras typically tolerate only about 10 km/h over, and rental firms pass camera fines to the renter with an admin fee.

Call 112 (or police 192) and report any accident involving injury or significant damage; for minor damage-only crashes, move vehicles clear and complete a European Accident Statement form. Leaving the scene of an injury accident is a serious offence.
