Thailand for Australian Drivers — Same Left Side, But You Still Need an IDP

Here is the rare bit of luck most travel guides bury: Thailand drives on the left, exactly like Australia. No mirror-image roundabouts, no reaching for a gearstick with the wrong hand, no fighting the reflex to drift to the right at a junction. For an Australian, that removes the single most dangerous part of driving abroad before you’ve even picked up the keys. The wheel sits on the right, you hug the left, and the road logic is the one you grew up with.

You still need an IDP — this part isn’t optional

Don’t let the familiar side fool you into thinking the paperwork is relaxed. Thailand legally requires a 1949-convention International Driving Permit carried with your Australian licence. It’s not a recommendation here the way it is in much of Europe — police checkpoints near tourist zones do ask, and a rental firm won’t hand over a car without it. Sort it through your state auto club (RACV, NRMA, RACQ and the rest) before you fly, because you cannot obtain one in Thailand. Confirm the exact requirement on the Driving Permit Checker.

The traffic is the actual challenge

The road rules are simple; the road itself is not. Thai traffic is dense, fast and dominated by motorcycles that filter past on both sides, undertake, and appear from side streets without much warning. In Bangkok the volume is relentless; outside the cities the danger flips to overloaded pickups, sudden stops and stray dogs. Speed limits — up to 80 km/h in towns (lower where signed), 90 rural, 120 on the newer motorways — are loosely observed by locals but firmly enforced on you by camera. Keep a generous following distance and assume any gap you leave will be filled by a scooter.

Smaller differences worth knowing

The alcohol limit is 0.05, matching most Australian states, but checkpoints near the islands and Bangkok nightlife are frequent, so treat it as zero. The only legally required equipment is a warning triangle. Petrol is cheap at around $1.25/litre, and the emergency number is 191 for police, with 1669 for ambulance — save both, as they differ from Australia’s 000.

If you’re touring the islands, factor in that many smaller routes and the ferries shape your days more than distance does. Full speed tables and regional notes sit on the Thailand driving guide.
