Does InterRent require an IDP in Cambodia?
Written by Daniel MercerUpdated July 2026
InterRent in Cambodia: the policy in plain terms
Asks for a licence translation for non-EU and non-Roman-alphabet licences across its European locations. Europcar's value brand for leisure travellers in Europe.
Cambodia drives on the right; an IDP is commonly requested for foreign drivers, and traffic in Phnom Penh is chaotic and best approached cautiously.
In Cambodia specifically, many rental companies and local authorities in Cambodia ask foreign drivers to present a translation of their licence alongside the original, so InterRent will typically ask for it at the counter. Self-drive desks ask for an IDP; many tourists hire a driver or tuk-tuk.
InterRent runs a europe network; at its Cambodia desks, foreign renters are asked for an International Driving Permit in the 1968 Vienna Convention format alongside the original licence. Cambodia drives on the right, uses the KHR, and sets a minimum driving age of 18, so an IDP is the document that removes any doubt at the counter.
What to bring to the InterRent counter in Cambodia
- Your original national driving licence (the IDP never replaces it).
- Your International Driving Permit in the 1968 Vienna Convention format.
- Your passport and a payment card in the main driver's name.
- Local payment for the KHR deposit; Cambodia drives on the right with a young-driver surcharge under 25.

InterRent's rental terms that affect your IDP booking
InterRent's minimum rental age is typically 19-21 depending on country (19 in Spain, 21 in the UK and France), and drivers aged roughly 21-24 (24 and under in some markets) pay a young-driver surcharge that varies by location, for example around 8.50 EUR/day (max ~93 EUR) in Spain, 12.95 EUR/day (max ~181 EUR) in France, and about 35 GBP/day (max ~350 GBP) in the UK; some vehicle categories require drivers to be over 25.
A refundable security deposit is pre-authorised (held, not debited) on the main driver's credit card at pick-up; the card (Visa or Mastercard, sometimes Amex) must be in the main driver's name with an expiry date after the return date, and debit cards are not accepted because their rules do not fit InterRent's deposit policy.
Additional drivers must present their own valid driving licence at the counter and sign the rental agreement at pick-up; InterRent charges an extra-driver fee per day that varies by location, though it is frequently included in promotional/package rates. The main driver must have held a full, valid driving licence for a minimum of 12 months (one year) prior to picking up the vehicle.
Cross-border travel and one-way rentals are restricted and must be authorised in advance; cross-border fees and one-way drop-off charges apply and vary by route, with certain countries (typically higher-risk or non-EU destinations) excluded entirely under the rental conditions.
InterRent requires a full, valid driving licence held for at least 12 months; for licences not written in the Latin/Roman alphabet (or otherwise not understandable to the rental agent), an International Driving Permit (IDP) must be presented alongside the original national licence, as the IDP is a translation and never replaces the physical licence.
Once you collect the keys in Cambodia
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.
