Does National require an IDP in Bosnia and Herzegovina?

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 vignette - tolls are paid at manual booths on tolled A1 motorway sections (e.g. Sarajevo-Zenica, Sarajevo-Tarcin, Banja Luka-Doboj); pay in cash in Convertible Marks (BAM) or euros, with most booths also accepting cards.

Towns like Sarajevo, Mostar and Banja Luka use signed paid zones and car parks payable by ticket machine, SMS or attendant; spaces in old-town centres are scarce, so guarded lots or hotel parking are the safest option.

Police issue on-the-spot fines for speeding, no seatbelt, daytime-headlight and phone offences, often payable in cash; the blood-alcohol limit is a strict 0.03% (zero for new and professional drivers), and headlights must be on 24/7 year-round.

Dial 122 for police (124 ambulance, 112 general). Do not move vehicles, switch on hazard lights and set out the warning triangle; a police report is required for insurance, and any visible damage should be reported because driving a visibly damaged car out of the country can be questioned.
