Does National require an IDP in Yemen?

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 developed motorway or electronic toll network; long-distance routes instead pass through numerous military and tribal checkpoints where informal payments or document checks, rather than formal tolls, are the norm. Carry cash and copies of your IDP, passport and any travel permits at every checkpoint.

There are no organised paid parking zones or apps; in Sana'a and Aden you simply park on the street, ideally in a guarded hotel compound or where an attendant watches the car for a tip. Vehicle theft and carjacking are real risks, so never leave a car unattended in an unsecured spot.

Formal traffic-fine enforcement is weak and inconsistent amid the conflict; the bigger risks are detention or fines at checkpoints for missing permits, and a strict nationwide alcohol ban means any drink-driving is treated severely. Do not photograph checkpoints, police or military.

Stop and do not move the vehicles; there is no reliable single emergency line nationwide, so contact local police or the nearest checkpoint/military post, which often handle incidents. Obtain whatever written report you can for insurance, and be aware that injury crashes can trigger tribal blood-money (diya) claims that are settled locally.
