Does National require an IDP in Hong Kong?

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.

Hong Kong has numerous toll tunnels and roads (fees roughly HK$0-HK$75 depending on tunnel and vehicle) now moving to the cashless HKeToll system, where a vehicle tag is read automatically and billed. Rental cars are tag-equipped and tolls are charged back to the renter.

On-street metered bays (30 minutes to 2 hours) are paid by Octopus card or the app, and commercial car parks dominate, with busy-area hourly rates above HK$50. Illegal parking draws a fixed penalty (raised to HK$400 from 2026), wheel-clamping or towing.

Fixed-penalty speeding fines run HK$320 (up to 15 km/h over) to HK$1,000 (over 45 km/h over), with demerit points and possible disqualification; phone use and no seatbelt are also penalised. Rental firms forward camera/fixed-penalty notices to the renter plus an admin fee.

Dial 999 for emergencies; you must stop, exchange details, and report any accident to police within 24 hours (immediately if there is injury). A police report is needed for the rental company and any insurance claim.
