Does Alamo require an IDP in Cambodia?

Alamo's standard minimum rental age in the US is 21 (18 in Michigan and New York where state law requires it); renters aged 21-24 pay a "young/youthful driver" surcharge that averages about $25 per day but varies by location (for example roughly $13/day in Michigan and $20/day in New York), and under-25 renters may be restricted to certain car classes.

A major credit card in the primary renter's name is required at most locations; debit/check cards bearing a Visa, Mastercard or Discover logo are accepted at airport locations only with a ticketed return travel itinerary (Discover not accepted in Canada), and the name/address on the card and license must match, with a hold placed at pickup that reduces available funds.

Additional authorized drivers typically cost about $15 per day each (around $5/day in New York), and every additional driver must also meet the minimum-age and license requirements; some promotions or contracted/corporate rates waive the fee. Alamo requires each driver to hold a valid, unexpired driver's license; the license must have been issued before the rental and held for the qualifying period, with locations commonly expecting it to have been held for at least 1 year.

Vehicles rented in the US may typically be driven throughout the US and Canada but cannot be taken into Mexico; vehicles rented in Canada may be driven in Canada and the US. Cross-border and one-way rentals must be disclosed and authorized at the counter, and one-way availability and drop fees vary by location.

Alamo states an International Driving Permit cannot be used on its own and the home-country license must always be presented; an IDP is recommended (not required) when the license uses Roman/English letters, but is required when the license is in a non-Roman alphabet (e.g. Russian, Japanese, Arabic), with a typed professional translation as a substitute if no IDP is available.

National Road tolls and the country's first expressway, the Phnom Penh-Sihanoukville Expressway, use distance-based tolls (about USD 12 each way for a car), paid in cash, by ANPR plate-billing, or via an ETC on-board unit topped up through local banking apps.

In Phnom Penh park in guarded paid lots at malls and markets, where attendants give a ticket and may chock motorbikes; street parking is informal and congested, and illegally parked cars risk clamping or removal by district authorities.

Speeding (the leading crash cause), no seatbelt/helmet and phone use draw fines that traffic police frequently collect on the spot in cash; enforcement and amounts vary, and fines were even temporarily suspended in 2025 amid fuel-price pressure.

Dial 112 (or 117/119 for police/ambulance); do not move vehicles after a serious crash and wait for traffic police, as a report is needed and at-fault foreign drivers are often expected to negotiate on-the-spot compensation.
