Thailand on a Canadian Licence — IDP Required & the Left-Side Switch

Thailand is built for road trips — island-hopping in the south, hill country up north — but it is also one of the harder Southeast Asian countries for a Canadian to drive cold. Two things matter far more than the rest, and the paperwork is genuinely the strict one here.

The IDP is not optional

Unlike many countries where an International Driving Permit is a polite suggestion, Thailand requires it. Rental companies routinely refuse to hand over keys without one, and at the roadside checkpoints that dot the tourist provinces, an IDP plus your Canadian licence is what keeps a stop short. Sort it through CAA before you leave Canada — it is a five-minute counter job at home and impossible to arrange once you land. Check exactly what applies to you 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 is the single biggest hazard, and it 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. Pick the car up somewhere quiet, not in central Bangkok or Phuket town, and stay deliberate at every junction until left stops feeling alien.

Motorbikes are the traffic, not an exception

The thing photos never prepare you for: scooters and small motorbikes fill every gap, undertake, filter up both sides at lights and appear from side-sois without warning. Treat the lane edges as live at all times and shoulder-check constantly. Town limits are 50 km/h, rural roads 90, motorways 120 — but the realistic pace in any built-up area is set by the bikes, not the sign.

Money matters

The alcohol limit is 0.05 BAC, stricter than Canada’s 0.08, and checkpoints near the islands run hard in high season — treat it as no drinking before driving. A minor speeding penalty is roughly THB 500-1,000 (≈ €13-26), often paid on the spot, so carry cash. Petrol is about $1.25/litre and the emergency number is 191.
