Pre-departure checklist for Cambodia

7 legal must-haves. Print it, tick them off, throw it in the glovebox.

  • 1968 IDP plus UK/EU licence

    Cambodia recognises the 1968 Vienna Convention IDP, which must be carried alongside your home UK or EU photocard licence; the older 1949 IDP is not officially accepted.

  • Passport with 6 months validity

    Carry your passport at all times when driving; police checkpoints routinely ask foreigners for ID and visa stamps.

  • Third-party motor insurance is compulsory

    Green Cards are not valid; buy local third-party cover (Forte, Asia Insurance) at the border or in Phnom Penh from around USD 30/year. Rental cars include it.

  • Drive on the right

    Cambodia drives on the right-hand side, opposite to the UK; many local vehicles are still right-hand-drive imports which complicates overtaking.

  • Speed limits 100 / 90 / 40 km/h

    Expressway 100 km/h, rural roads 90 km/h, urban areas 40 km/h, and 30 km/h past schools; limits are poorly signed and strictly enforced by mobile police.

  • BAC limit 0.5 g/L

    Blood alcohol limit is 0.50 g/L (0.25 mg/L breath); random roadside breath tests are common, especially around Phnom Penh on weekend evenings.

  • Seatbelts and helmets

    Front-seat belts are compulsory, and motorcycle helmets are required for the rider (passengers technically too, though widely ignored); fines start at around USD 15.

Documents

1968 IDP plus UK/EU licence

Required

Cambodia recognises the 1968 Vienna Convention IDP, which must be carried alongside your home UK or EU photocard licence; the older 1949 IDP is not officially accepted.

Passport with 6 months validity

Required

Carry your passport at all times when driving; police checkpoints routinely ask foreigners for ID and visa stamps.

Cambodian temporary local licence for stays >30 days

Recommended

For longer visits you must convert your IDP to a Cambodian licence at the Ministry of Public Works and Transport in Phnom Penh; cost around USD 40.

Third-party motor insurance is compulsory

Required

Green Cards are not valid; buy local third-party cover (Forte, Asia Insurance) at the border or in Phnom Penh from around USD 30/year. Rental cars include it.

Hire a car with driver instead of self-driving

Recommended

FCDO and most insurers advise visitors against self-driving due to road conditions and accident rates; a car with driver costs around USD 50-80/day and is the norm.

Driving rules

Drive on the right

Required

Cambodia drives on the right-hand side, opposite to the UK; many local vehicles are still right-hand-drive imports which complicates overtaking.

Speed limits 100 / 90 / 40 km/h

Required

Expressway 100 km/h, rural roads 90 km/h, urban areas 40 km/h, and 30 km/h past schools; limits are poorly signed and strictly enforced by mobile police.

BAC limit 0.5 g/L

Required

Blood alcohol limit is 0.50 g/L (0.25 mg/L breath); random roadside breath tests are common, especially around Phnom Penh on weekend evenings.

Chaotic traffic and unwritten rules

Good to know

Expect tuk-tuks, motos and livestock on all roads, frequent wrong-way driving, and an informal rule that the larger vehicle has priority; horn use is constant and expected.

Emergency number 119 / 117

Good to know

Dial 119 for ambulance, 118 for fire, and 117 for police; English-speaking operators are limited, and response times outside Phnom Penh are very slow.

Tolls

Phnom Penh-Sihanoukville Expressway toll

Good to know

The PPSHV Expressway charges by class at manned booths, roughly USD 12 (about EUR 11) one-way for a car over the 187 km route; pay in USD cash or KHR. No other motorways exist.

Required equipment

No mandatory in-car kit, but carry basics

Recommended

There are no legal requirements for hi-vis vest, triangle or extinguisher, but a first-aid kit, torch and spare tyre are strongly advised given remote breakdown risk.

Seatbelts and helmets

Required

Front-seat belts are compulsory, and motorcycle helmets are required for the rider (passengers technically too, though widely ignored); fines start at around USD 15.

Environment

Avoid driving at night and in monsoon

Recommended

Rural roads are unlit, with unmarked livestock and potholes; the May-October monsoon brings flash flooding that closes provincial roads without warning.

Money

Dual currency: USD and Riel

Good to know

US dollars are accepted everywhere alongside Cambodian Riel (KHR, ~4,100 to USD); fuel costs around USD 1.20-1.40/litre (EUR 1.10-1.30). Carry small USD notes.

Cash declaration limit USD 10,000

Good to know

You must declare cash equivalent to USD 10,000 or more at the border; fuel stations in towns take cards but rural pumps are cash-only and tipping is not expected.
