Alcohol & Driving

Drink-Driving Rules in Cambodia

General limit: 0.05 g/dL

Reaction time, judgement and night vision all degrade well below any legal threshold — the only limit that guarantees safety is 0.00. Alcohol is a factor in a large share of the world's fatal crashes, and enforcement in Cambodia can include checkpoints, licence loss and jail.

FAQ

Which side of the road does Cambodia drive on?

Cambodia drives on the right-hand side of the road (like most of the world).

What is the drink-driving limit in Cambodia?

The general limit is 0.05 g/dL BAC. Remember: impairment starts well below the legal limit.

Do I need an International Driving Permit in Cambodia?

Yes — an IDP (or a locally issued permit) is required or strongly enforced for foreign visitors driving in Cambodia. Get one in your home country before you travel.

Is it safe to drive in Cambodia?

By the numbers, Cambodia has a WHO-estimated road death rate of 17.1 per 100,000 people (global average about 15), which is close to the global average — it ranks 71 of 195 countries from most to least deadly.

Most road deaths anywhere happen at night, at higher speeds and on rural roads, so plan long drives in daylight and follow the posted limits.
