Driving Requirements
Cambodia accepts foreign driver's licenses for visitor use. But an International Driving Permit is strongly recommended alongside your home-country license. The IDP provides a translated, universally recognized document that simplifies police stops, without one, informal on-the-spot payments are common even when your license is technically valid. Some rental companies in Siem Reap require an IDP as a condition of rental, independent of what local law mandates.
Cambodia's legal minimum driving age is 18. Rental company age requirements are a separate matter and vary by operator: some companies rent to drivers from age 18, while others set a minimum of 21 or 25, for larger vehicles or higher-value cars. Confirm the age policy directly with your rental company before booking, as young-driver surcharges may also apply.
Third-party liability insurance is a legal requirement under Cambodian road law. Most rental companies include basic third-party coverage in their quoted rate. But the scope of that coverage varies by operator. Collision Damage Waiver (CDW) is typically offered as a paid add-on rather than included by default. Checking whether your travel insurance or credit card provides supplemental rental car coverage before you arrive is worthwhile.
Deposit requirements are set by individual rental companies, not by law, and vary considerably. Established operators generally place a hold on a credit card. Some smaller or budget operators may request your passport as a deposit, a practice that is inadvisable since it leaves you without identification. Clarify deposit terms and the release timeline in writing before signing any rental agreement.
Cambodia drives on the right-hand side of the road. Traffic in Siem Reap is often dense and unpredictable, with motorbikes frequently ignoring lane markings and signals, defensive driving is essential rather than optional. Speed limits are posted in kilometres per hour. Road surfaces outside the city centre can deteriorate significantly, and conditions worsen during the rainy season (roughly June through October), making higher ground clearance worthwhile for any routes beyond the main tourist area.
Helpful Tips
Siem Reap's newer Angkor International Airport (SAI) sits considerably further from the city center than the former airport did, so weigh the convenience of an on-arrival airport pickup against the longer drive into town, many travelers find collecting a car from a city-center office the next morning more practical and often less expensive.
Before accepting the vehicle, shoot a timestamped video walk-around covering every panel, the windshield, and the wheel rims, because damage deposit disputes are common with local operators whose paper inspection forms often omit pre-existing marks. Also check whether your credit card or travel insurance provides collision coverage before paying for the rental company's CDW, as policies vary significantly between companies.
Google Maps covers central Siem Reap and the main Angkor temple roads reliably. But download an offline Cambodia map in Maps.me before you go, unpaved access tracks to lesser-visited temples and rural routes north of the city are poorly represented in Google's data; built-in GPS units are rare in local rental fleets and typically outdated when present.
Virtually all rental vehicles here take regular unleaded petrol. Fuel stations are plentiful within Siem Reap town but become sparse quickly on roads heading toward Preah Vihear or the Cambodian countryside, so fill the tank before leaving the city on any day trip, full-to-full is the standard return policy, though some companies offer prepaid fuel at pickup, so confirm the terms in your rental agreement.
Parking at Angkor Wat and the main Angkor Archaeological Park is straightforward via clearly signed, paid lots managed by the site. Central Siem Reap near Psar Chas (Old Market) and the Pub Street corridor is congested with tuk-tuks and motos making on-street spots unreliable, so for overnight storage your hotel's car park is almost always the simplest and safest option.
Driving Warnings
Motorbikes routinely travel against traffic flow on one-way streets and along the wrong side of dual carriageways, this is prevalent on Sivatha Boulevard and side streets near the Old Market. Always check both directions before turning or pulling out, even when you technically have right of way.
Police conduct roadside document checks on National Road 6 and major arterials leading into the city. Foreign drivers are legally required to carry both a valid International Driving Permit and their home-country license simultaneously, and driving without one can result in on-the-spot fines.
The roads approaching the Angkor Archaeological Park experience severe congestion at sunrise (roughly 5:00, 6:30 AM) and again at sunset, when tour buses, tuk-tuks, and private vehicles converge at the main gate simultaneously. If you are not visiting the temples, avoid this corridor during those windows.
During the wet season (typically May through October), low-lying roads near the Old Market and residential streets in central Siem Reap can flood to a depth that stalls standard vehicles. Conditions can change within hours of heavy rain, so check road status before setting out and avoid crossing standing water of unknown depth.
