Does National require an IDP in Austria?

The minimum age to rent is typically 21 (18 in Michigan and New York, as required by state law); renters aged 21-24 pay a "Youthful Surcharge" of approximately $25 per day (varies by location, lower in some states such as $5/day in New York) and may be restricted to certain car classes.

A major credit card (Visa, MasterCard, Amex) in the primary renter's name with sufficient available credit is required; National generally does not accept debit cards, and renters without a ticketed return travel itinerary must provide a hold/deposit typically between $300 and $400 depending on location and vehicle class.

The renter's spouse or domestic partner who meets the same age and licence requirements drives free; other additional authorized drivers cost about $15 per day (typically $5/day in New York), and must be at least 21 with a valid licence. National requires a valid, unexpired full driver's licence held by the renter; for under-25 drivers some locations require the licence to have been held for at least one year, though National does not publish a uniform minimum tenure across all locations.

Vehicles rented in the U.S. or Canada are prohibited from being driven into Mexico; U.S.-Canada cross-border travel is generally permitted but one-way US/Canada drop-offs are limited to participating locations, and rentals originating in certain Mexican cities (e.g. Tijuana, Mexicali, Hermosillo, Monterrey, Saltillo) may cross into the U.S. after purchasing an extension of liability protection (about $10 USD/day).

National states that an International Driving Permit (IDP) is commonly requested in select countries and is generally recommended when travelling abroad; specifically, overseas travelers whose licence uses a non-Roman alphabet may need to present an IDP alongside their home-country licence.

All motorways and expressways require a vignette (digital or sticker): a 1-day digital vignette was introduced in 2025, plus 10-day, 2-month and annual options. Several Alpine routes (Brenner, Tauern, Arlberg tunnel, Grossglockner) charge separate tolls; driving without a vignette risks a minimum substitute toll/fine around EUR 120.

Cities use Kurzparkzone short-stay zones marked by blue lines and signs, paid by paper ticket/Parkschein or apps like HANDY Parken/EasyPark; Vienna's entire inner districts (1 to 9 and beyond) are a paid Kurzparkzone on weekdays. Illegal parking fines start around EUR 20 and wrongly parked cars are towed.

Police are strict and can demand immediate cash payment of fines up to about EUR 90 (a deposit for larger amounts); speeding, handheld phone use and no seatbelt are routinely enforced including by camera. Rental companies pass on camera fines with an administrative fee.

Call 133 for police or the pan-European 112 (ambulance 144); police must be called if anyone is injured or if drivers cannot agree, otherwise a police report is not mandatory for minor damage where details are exchanged. Place the warning triangle, wear the hi-vis vest, photograph the scene and complete the European Accident Statement; do not move vehicles if there are injuries.
