Does National require an IDP in South Sudan?

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 system; the road network is overwhelmingly unpaved outside Juba, so visitors pay nothing in formal tolls but should budget cash for informal checkpoint demands.

There are no organised paid parking zones; in Juba parking is informal kerbside, often watched by self-appointed attendants who expect a small cash tip, and vehicles should never be left unattended with valuables visible.

Enforcement is largely manual at checkpoints with on-the-spot cash fines negotiated in person; foreign drivers without proper documents risk vehicle hold-ups, and a 4x4 with comprehensive insurance is strongly advised as cover can be voided without an IDP.

After a crash do not move the vehicles if there are injuries; call police (the general emergency line is 777) and remain at the scene, as a police report is required for any insurance claim and leaving can be treated as a serious offence.
