Thailand on a UK Licence — Same Side, But an IDP Is the Law

For once, a destination where British drivers do not have to retrain the most basic instinct: Thailand drives on the left, exactly as you do at home. Roundabouts turn the way you expect and your mirror checks point the right way. The thing that catches Britons out has little to do with which side you sit on.

Which permit, and why you cannot sort it out in Bangkok

GOV.UK’s Thailand advice is specific: you need to carry both the 1968 version of the International Driving Permit and your UK licence while driving. It also says you cannot buy an IDP outside the UK, so the permit has to be in your hand before the flight. Our record shows the IDP as required for Thailand and valid for the length of your entry permit, normally up to three months. Carry the IDP, the licence and the passport as a set.

If you hold a Thai licence because you live there, the advice is different: residents can apply for a Thai licence using their UK one. This page is for visitors.

GOV.UK adds an insurance warning that matters more than any fine. Driving a car or riding a motorcycle without a valid licence could invalidate your travel insurance, so you would be unable to claim after an accident or injury. Many policies also expect you to hold the right UK licence category for the vehicle you ride.

Motorbikes are the real driving challenge

GOV.UK says Thailand has a high number of road traffic accidents, particularly with motorcycles, and that the WHO ranks it as one of the world’s deadliest countries for motorcycle fatalities. In a car you will share the road with a constant swarm of bikes that filter, undertake and emerge from side streets with little warning. Lane discipline is loose by British standards. In Bangkok and on the islands expect bikes on both sides at once.

Build in extra following distance, check the nearside mirror often, and accept that progress is slower than the map suggests. If you plan to hire a scooter instead, GOV.UK points out that machines in tourist areas are often unregistered and cannot legally be used on a public road, so read the lease and the insurance small print. By law you must wear a helmet.

Speed limits in mph

The town figure is well above a British 30 mph street, though lower limits apply where signed. The 120 km/h tollways feel faster because surrounding traffic varies so wildly in speed.

Fines: small in Thailand, with larger ones for serious cases

Thirty or more km/h over costs THB 2,000-5,000, with a possible court appearance. A rental firm will pass a ticket on to you, as covered in our guide to who pays driving fines abroad.

Alcohol

The British drink-drive question gets a straight answer: Thailand’s limit is 0.05, against the 0.08 used in England and Wales. Checkpoints around nightlife districts are common. The honest answer is zero before you drive.

In the car and on the phone

A warning triangle is required in Thailand, while the UK lists it as only recommended. Emergency numbers are 191 for police, 1669 for an ambulance and 199 for fire, nothing like 999. Save them before you leave the airport. Check the permit rule again with the driving permit checker and read the Thailand driving guide for local habits. To price a ticket, use the speeding fine calculator.

What about driving from the UK to Thailand?

People do search for it, but it is not a practical holiday plan: there is no road link you can treat as a normal route, and the permit, visa and insurance requirements multiply with every border. Most visitors fly and hire a car locally, which keeps the paperwork in one place.
