Driving in Krabi: Left Side Traffic, IDP and the Karst Roads
What the left side of the road, the roundabouts and the checkpoints around Krabi actually feel like, and the permit you need before you land.

The road network does the teaching, not a rulebook
Nobody learns to drive on the left from a paragraph. It happens road by road, and Krabi hands you four different ones in the first hour, each asking for something slightly different.
Highway 4
Phetkasem Road
Two lanes each way, sealed and wide, and the road most arrivals meet first. It is a forgiving place to get used to sitting on the right and steering with the karst towers on your left instead of your right.
Route 4034
toward Ao Nang
Wide and well surfaced the whole way, with a scatter of roundabouts that slow everyone down to walking pace. Treat those as practice, not an obstacle.
Route 4202
the northern beaches
Narrower, with tighter bends as it threads between limestone outcrops toward Klong Muang and Tubkaek. Shade drops suddenly where the rock overhangs the road.
Inland lanes
off Highway 4
Patched surfaces, no painted centre line in places, and a scooter or a dog around most bends. Slow down before you can see what is coming, not after.

Roundabouts, checkpoints, and what happens in between
Four things actually change the way you drive here. None of them are complicated once you have met them once.
The roundabout
Give way to traffic already on the roundabout, which now approaches from your right instead of your left. Slow in, look right, and let one gap pass if you are not sure. Every driver new to the left treats their first roundabout as an event, and it is over in a few seconds.
The scooter beside you
Scooters run along the inside of the lane, often where your left mirror is not pointed. Check that mirror before every turn and every pull away from a stop, not just the one behind you.
The rain that arrives without warning
A downpour can start and stop inside twenty minutes here, and the road surface stays slick under the karst shade after it passes. Ease off the accelerator earlier than feels necessary and add distance to the scooter ahead.
The checkpoint
Officers on Highway 4 and around the Ao Nang turn do stop hire cars. Slow down, pull in where waved to, and have your passport, home licence and International Driving Permit together rather than loose in a bag.
The permit paperwork, sorted into three pieces
The International Driving Permit is the one document a road rule cannot substitute for, so it earns its own section rather than a line inside the FAQ.
What the permit actually is
An International Driving Permit is a translation of your home licence into a standard format, issued by a motoring body in your own country before you travel. It rides alongside your licence, never in place of it, and Thailand does not issue one to a visitor after arrival.
What sits in the glovebox
Passport, home driving licence, International Driving Permit and the booking confirmation together, in one place, every time you drive. Splitting them between a hotel safe and a day bag is how one goes missing on the day it matters.
What an officer usually asks for
Licence and permit first, sometimes the rental paperwork after. Answers are short and the stop is short. Nothing here differs from what the roadside signage already expects of a Thai-registered driver.
What first-timers on the left told us afterward
The first roundabout out of the airport had my hands tight on the wheel. By the Ao Nang turn ten minutes later I had stopped thinking about which side I was on.
Henrik Kallio
Turku, Finland
Nobody mentioned the scooters would sit so close on the inside. Once I started checking that mirror on purpose it stopped bothering me.
Marisol Guzman
Guadalajara, Mexico
Got waved into a checkpoint near the airport turn on day one. Permit and licence were in the glovebox together and the whole stop took under a minute.

Six things worth knowing before you turn out of the yard
Every car here is automatic
One gearbox habit you do not have to learn while you are also learning the side of the road.
Highway 4 is the spine
Wide and sealed the whole way through the province.
IDP arranged at home
It cannot be issued once you land.
Checkpoints do check
Keep the paperwork together, not scattered.
Scooters ride the inside lane
Mirror discipline matters more than speed. Most close calls happen at a slow turn, not on the open road, when a rider comes up on the left just as you commit to the corner.
Rain clears fast
The shade under the karst stays slick after it does.
