Driving Requirements
Cambodia recognizes foreign driving licenses. But carrying an International Driving Permit (IDP) alongside your home-country license is strongly recommended and may be treated as legally required at traffic stops, where officers may not be able to read a foreign-language license. An IDP must be obtained from your home country's automobile association before departure, it cannot be issued once you are abroad. Without one, you risk fines or informal payments at checkpoints.
Cambodian traffic law sets the legal minimum age to drive a passenger car at 18. Rental company age thresholds are a separate, independent policy that varies by provider: some local operators rent from 21, while international agencies and those with newer fleets often require drivers to be 25 or older and may charge a young-driver surcharge below that threshold. Always confirm the age requirement directly with your specific rental company before booking.
Cambodian law requires all vehicles to carry third-party liability insurance covering injury or property damage to others, and rental companies build this into their base rate to comply. Collision Damage Waiver (CDW) and theft protection are additional products offered by rental companies, they limit your personal financial exposure for damage to the rental vehicle itself. But they are rental company policies, not legal requirements. Coverage limits and exclusions vary by provider, so read the policy details before accepting or declining.
Rental companies in Cambodia vary considerably on deposit requirements: international agencies typically place a credit card pre-authorization hold, while smaller local operators may require a cash deposit or, in some cases, retain your passport as collateral, a practice that carries its own risks. Confirm the deposit amount, the hold method accepted, and the refund timeline in writing before signing. Some operators do not accept debit cards for the security hold.
Cambodia drives on the right-hand side of the road. Traffic enforcement is inconsistent, and outside Phnom Penh and Siem Reap many roads are poorly lit, unpaved, or unmarked. Motorbikes, tuk-tuks, and livestock routinely share the carriageway, and right-of-way is often negotiated informally rather than by posted rules. Driving after dark outside major urban areas carries meaningfully higher risk and is generally discouraged for visitors unfamiliar with local conditions.
Helpful Tips
Phnom Penh's airport (PNH) has rental counters inside the terminal, making pickup convenient. But Siem Reap's newer SAI airport sits roughly 50 km from the city center, picking up a vehicle in town rather than at SAI can save significant transfer time and typically costs less.
Photograph every scratch, dent, and interior scuff before leaving the lot and confirm the agent countersigns a written condition report. Insurance terms vary widely between companies, with some budget operators offering only a high-excess option rather than a true collision damage waiver, so ask explicitly what excess you are liable for and whether your credit card covers CDW in Cambodia, many do not.
Google Maps covers Cambodia's national highways and main city streets reliably. But rural and unpaved roads are frequently missing or outdated. Download an offline map pack (Google Maps offline or Maps.me) before departing the city, as mobile data becomes unreliable once you leave the major corridors.
Most rental vehicles run on petrol (gasoline); full-to-full fuel policies are standard at established agencies, and stations are plentiful along the national highway network. But in remote provinces roadside vendors sell fuel by the bottle with inconsistent quality, fill up at a proper station before heading off the main routes.
In Phnom Penh, informal fee collectors operate at most curbside spots throughout the day and expect a small payment. Overnight hotel parking is generally available but should be confirmed at check-in, and leaving an unattended vehicle on the street overnight in the capital is not advisable.
Driving Warnings
Cambodia legally requires a valid International Driving Permit (IDP) alongside your home country license, driving without one is a fineable offense, and police checkpoints on national highways, including National Road 6 between Phnom Penh and Siem Reap, routinely check documents and vehicle registration.
During the rainy season (roughly May through October), provincial roads and sections of national highways can flood rapidly and become impassable within hours. Always check local conditions before departing on routes outside major cities, as GPS will not reflect water levels.
Motorcycles and tuk-tuks frequently travel against traffic flow, run red lights, and spread across all lanes simultaneously, treat every urban intersection in Phnom Penh and Siem Reap as an uncontrolled merge point regardless of which direction the signal favors you.
Night driving outside Phnom Penh and Siem Reap carries serious risk: rural roads are largely unlit, and vehicles without functioning headlights, pedestrians, and livestock on the carriageway are common hazards after dark, most experienced drivers avoid rural travel between dusk and dawn.
