Does National require an IDP in Nepal?

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.

There are no electronic toll tags; tolls are minor cash booths on a few stretches such as the Nagdhunga and Kanti Lokpath sections and the Kathmandu-Tarai/Madhesh fast-track when fully open, typically a few hundred rupees per car. Most ordinary highways including the Prithvi Highway are toll-free.

City parking in Kathmandu is largely informal paid lots and attended kerbside spaces where a collector issues a paper ticket for roughly NPR 20-50 per hour; there are very few meters or apps. Illegally parked vehicles in core areas of Kathmandu and Lalitpur can be clamped or towed by the metropolitan traffic police.

Traffic police issue on-the-spot fines, often payable in cash, for speeding, no seatbelt and mobile-phone use, with drink-driving (zero-tolerance MaPaSe checks) drawing heavy fines and possible licence action. Rental firms pass any later-issued fines and damage to the renter, usually against the security deposit.

Dial 100 for police (or 102 for ambulance); in any injury or serious-damage crash do not move the vehicle and wait for traffic police, as crowds can gather quickly. Report immediately and exchange details, and notify the rental company at once since informal on-the-spot cash settlements are common but risky for foreigners.
