Does National require an IDP in Papua New Guinea?

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.

Papua New Guinea has no toll roads or electronic toll/vignette system; the limited sealed highway network (such as the Highlands Highway) is free but often in poor, unsealed condition.

There are no formal paid-parking zones; in Port Moresby use guarded, fenced car parks at hotels and shopping centres (e.g. Vision City) rather than street parking, which carries a real theft and carjacking risk.

Speed limits are about 60 km/h in towns and up to 100 km/h on open highways; police issue on-the-spot fines for speeding, seatbelt and phone offences, and rental firms recover any fines from the renter. Roadblocks and informal demands occur.

The national emergency number is 000 (police), though response is slow and limited outside Port Moresby; after a serious crash do not stop in unsafe areas and instead drive to the nearest police station to report, as a report is required for insurance.
