Does National require an IDP in Sierra Leone?

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 is no national electronic toll or vignette scheme; the main paved corridors (such as the Freetown-Bo highway and the Freetown toll road / Wellington-Masiaka stretch) may levy a cash toll at barriers, otherwise roads are free.

Street parking in central Freetown is congested and largely informal, with attendants expecting a small cash tip; use hotel or guarded lots where possible and avoid leaving vehicles unattended on busy streets.

Foreign drivers most often encounter on-the-spot police checks for documents and seatbelt/phone use, with fines typically paid in cash; enforcement is uneven, so always carry your IDP, licence and rental papers to avoid roadside disputes.

Call the police (emergency line 999, or 019) and wait for an official report; do not move vehicles after a serious or injury crash, and note that road signage and accident protocols are inconsistent so document the scene yourself with photos.
