Cambodia for US Drivers 2026: A Cambodian Licence Rules
United States
Cambodia
Plan on a Cambodian driving licence: Canada says you must have and carry one, and UK advice requires it for long rentals or private cars. The U.S. State Department adds: do not drive at night outside cities.
Americans are used to a licence that works almost anywhere with an IDP stapled to it. Cambodia is the place where that habit stops being enough, and the U.S. State Department’s road guidance adds a second, more urgent warning: do not drive after dark outside the cities.
What the licence rule really is
The Government of Canada’s advice says drivers must have and carry a Cambodian driver’s licence. GOV.UK says the same for long-term rentals and private vehicles, while noting that hire shops sometimes ask to see a 1949 International Driving Permit for a car or a motorbike over 125cc. Read together, a US licence with an IDP is something a rental counter may inspect, not the document that makes you legal. If you want to drive yourself, budget time for a Cambodian licence before you collect keys; otherwise hire a car with a driver. Never hand over your passport as a deposit for a motorbike.
The State Department points the other way on one detail: it tells US citizens to carry photocopies of their passport and US licence and leave the originals in a hotel safe, because of the risk of theft or confiscation. Keep copies on you, and if you hold a Cambodian licence, carry that one.
Daylight driving only
The State Department is plain about timing. Do not drive at night in Cambodia outside city limits. It recommends travel in daylight between 6:30 a.m. and 5:30 p.m. Roads between major areas are adequate, but roads leading to rural areas are poor, and roadside assistance is non-existent. In the rainy season conditions get much worse: serious flooding occurs from June through November, dirt roads become hard to use after heavy rain, and only the National Route highways can be travelled, with caution.
Its description of other road users is blunt: drivers routinely ignore traffic laws, vehicles are poorly maintained, and intoxicated drivers are commonplace in the evening. Traffic is a mix of cars, trucks, motorcycles, bicycles and tuk-tuks, and there are frequent bus accidents. Plan your day around being off the road by late afternoon.
Speeds a US driver will find slow
The side of the road is the same as home, so the adjustment is speed and flow.
| Road | Limit | In mph |
|---|---|---|
| Towns | 40 km/h | 25 |
| Rural roads | 60 km/h | under 40 |
| Better highways | 100 km/h | 62 |
Compare that with the typical 65-75 mph on a US interstate. Cambodia’s alcohol limit is 0.05, against 0.08 at home.
If something goes wrong
If you are in an accident, the State Department says to cooperate with the police and contact your insurance company for guidance in dealing with the other party. Organised emergency services for accident victims are non-existent outside major urban areas, and those in the cities are inadequate. Our record lists 117 for police, 119 for an ambulance and 118 or 666 for the fire service. At home you dial 911 for everything, so save these separately before you go. Travel insurance that covers driving and evacuation matters more here than in most countries.
Alternatives to driving
The State Department advises caution on inter-city buses, including those to Siem Reap and Sihanoukville, and says not to use moto-taxis despite their wide availability, because of safety concerns. Personal belongings are easy to steal on tuk-tuks and cyclos. For a first visit, a hired car with a driver on daylight routes is the lower-risk option.
Wider rules are on the Cambodia driving guide, and the Driving Permit Checker covers other countries on your trip.
Before booking a hire, ask the company in writing which licence it accepts and whether its insurance still pays out when the driver holds only a foreign licence and an IDP. If the answer is vague, assume the cover does not apply and choose a car with a driver instead. Keep photocopies of your passport and licence with you and the originals in the hotel safe, as the State Department suggests.

Frequently Asked Questions
An IDP is not the document that counts. Government of Canada advice says drivers in Cambodia must have and carry a Cambodian driver's licence, and UK advice says one is needed for long-term rentals or private vehicles. Some hire shops ask to see a 1949 IDP for cars or bikes over 125cc, but treat that as their condition, not a licence to drive.
Yes. Cambodia drives on the right, the same as the United States, so your instincts at junctions carry over, even if local traffic flow does not.
The limit is 0.05, below the typical US 0.08. Intoxicated drivers are commonplace in the evening hours, according to the U.S. State Department, so treat any alcohol as a reason to stay off the road.
The State Department says you should not drive at night in Cambodia outside city limits, and recommends travel in daylight between 6:30 a.m. and 5:30 p.m.
