Canadian Licence in Thailand 2026: IDP Required, 0.05 BAC

Yes, a Canadian licence is usable in Thailand, but not on its own. Global Affairs Canada puts it plainly: you must carry an international driving permit or a Thai driver’s licence to drive there. Then comes the physical change: Thailand drives on the left, towns allow up to 80 km/h unless signs say less, and the alcohol limit is 0.05, below the 0.08 you know from Canada.

Your case: That 0.05 is the number most likely to catch a visiting Canadian out, because it is stricter than the limit you calibrate against at home. The BAC calculator turns your own weight, drinks and hours into the reading a checkpoint breathalyser would give.

Get the permit through CAA

Canada and Thailand are both parties to the 1949 Geneva Convention, and the Canadian permit is issued through the Canadian Automobile Association. Global Affairs Canada notes that it is valid for one year from the date of issue and covers only the vehicle classes on your Canadian licence. Apply before you leave; it cannot be arranged in Bangkok. Scooters need more: riding a motorcycle is illegal without a Thai motorcycle licence or an IDP carrying a motorcycle endorsement. Check the rest of your route with the Driving Permit Checker.

You drive on the left here

Canada drives on the right; Thailand drives on the left. The mirror image of everything you do by reflex bites in the first hour: pulling out of a 7-Eleven car park, taking a roundabout the wrong way, glancing left when the threat is on your right. Collect the car somewhere quiet rather than in central Bangkok or Phuket town.

Motorbikes are the traffic

Scooters and small motorbikes fill every gap, filter up both sides at lights and appear from side sois without warning. The WHO’s 2023 profile gives the legal maximums as 80 km/h in towns, 90 on rural roads and 120 on motorways, but the realistic pace in any built-up area is set by the bikes, not the sign.

Alcohol, rentals and emergencies

The limit is 0.05 g/dl, and 0.02 for young or novice drivers. Global Affairs Canada warns that drunk driving and crashes spike around 1 January and Songkran in mid-April. It also reports hire firms falsely claiming damage or holding passports as collateral, so photograph the vehicle before you sign and never leave your passport. Call 191 for police and 1669 for an ambulance. The Thailand driving guide has the full rulebook.
