Does National require an IDP in Dominican Republic?

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.

Toll booths ('peajes') sit on the main highways radiating from Santo Domingo and on the Samana toll road; pay cash in Dominican pesos (booths rarely take cards), with charges of roughly RD$60-300 (about US$1-5) per booth depending on the route.

Parking is free in most areas but paid or attended in larger town centres; in Santo Domingo's Zona Colonial use guarded lots, tip the informal car-watchers, and never leave valuables visible.

DIGESETT issues fines for speeding, phone use and no seatbelt (commonly RD$500-1,500, rising for serious excess and possibly licence points/bans); officers may seek payment roadside, and rental firms pass camera and unpaid-toll fines back to the renter's card.

Dial the nationwide 911; call the rental company and do not move the car unless it is unsafe to leave it where it stopped, and wait for DIGESETT traffic police to document the scene.
