Does National require an IDP in Comoros?

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 motorway toll systems or vignettes in Comoros; the road network is short island roads with no electronic tolling. Budget only for fuel and the occasional informal road-block, not tolls.

Parking is informal and unmetered, mostly on-street in Moroni; there are no colour-coded paid zones or apps. Informal attendants may watch your car for a small tip, and you should avoid blocking narrow village lanes.

Drink-driving is treated strictly with a near-zero tolerance, carrying fines and possible detention. Police checkpoints are common near town exits; fines are typically settled on the spot in cash, so keep your documents visible and ask for a receipt.

Stop at the scene, do not move vehicles if there are injuries, and wait for police; contact the gendarmerie/police (emergency 17) to file a report needed for insurance. Exchange details with the other driver where possible.
