Does National require an IDP in Sri Lanka?

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.

Expressways (E01 Southern, E03 Airport, E02 Outer Circular) are tolled with cash booths and the contactless 'TAGRush'/expressway pass; tourists typically pay cash, with charges of a few hundred to roughly LKR 1,000+ depending on distance.

Urban parking in Colombo and tourist towns is largely paid on-street with attendants/wardens collecting cash, plus private and mall lots; unattended or restricted-zone parking can be ticketed or wheel-clamped.

Police issue on-the-spot fines (spot-fine slips paid later at post office or now via online/eRL channels) for speeding, no seatbelt and mobile-phone use; tourists driving without a valid Recognition Permit risk prosecution and rejected insurance claims.

In any injury accident you must stop, not move vehicles, and call Police on 119 (ambulance 1990 Suwa Seriya); a police report is needed for insurance, and driving without the Recognition Permit can void your claim and lead to prosecution.
