Once you're driving in Cambodia
Destination-specific detail sourced from national road authorities, motoring clubs and rental policies — the things that catch cross-border drivers out.
Driving on a foreign licence
Foreign tourists need their national licence plus a 1949 International Driving Permit, which Cambodia has accepted since 2020; carry the original licence as photocopies are not accepted. Long-stay drivers should convert to a Cambodian licence.
Tolls & road charges
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.
Parking in the cities
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.
Fines & camera enforcement
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.
If you have an accident
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.
Driving in the capital
Phnom Penh traffic is dense and unpredictable, dominated by motorbikes and tuk-tuks that filter from all sides; vehicles often ignore lane markings and turn across traffic, so defensive driving is essential.
