Does National require an IDP in Greece?

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.

Major motorways (Attiki Odos, the A1, the Olympia Odos and others) use staffed cash/card toll plazas charging fixed per-section amounts of roughly EUR 1.50-3; there is no national vignette, and Crete has no toll roads at all. An optional e-pass transponder exists but tourists normally just pay at the booth.

City-centre parking in Athens and Thessaloniki is controlled-zone paid parking (white/blue marked bays) paid via app or kiosk ticket, and is genuinely scarce. White-and-yellow kerbs and resident-only zones are off-limits and towing/clamping is common, so a guarded public garage is the safer choice.

Under the September 2025 Traffic Code fines are steep and digital: exceeding the limit by even up to 20 km/h is EUR 150, and handheld phone use and no-seatbelt each draw large fines with possible licence-point penalties. Camera and digital violations are increasingly forwarded to rental firms and billed to your card.

Call 112 for emergencies; for any injury or dispute you must wait for and obtain a police report, which insurers and rental firms require. Vehicles should not be moved until documented if there is injury, and both driver and rental company can each be fined EUR 1,000 if the driver lacked a required IDP.
