Driving in Thailand on a US license, Bangkok transit

Bring your US license and an International Driving Permit for the first stretch. Once you're living here, the Department of Land Transport expects you to get a Thai license, and in central Bangkok the train is usually faster than any car.

The short version

For short stays, carry your US license together with an International Driving Permit (IDP). In the US, AAA issues IDPs for USD 20 [1].
Living here? Convert to a Thai license at a Department of Land Transport (DLT) office. You'll need a Non-Immigrant visa, proof of address, a medical certificate and your US license [2][3].
Expect vision and reaction tests and a written theory test. The DLT has been tightening the rules for foreigners since 2025, and offices differ, so check before you go [2][3][4].
Thailand drives on the left, and its roads are among the world's deadliest: WHO estimated about 18,218 road deaths in 2021, and motorcyclists were 83.8% of them [5].
In Bangkok, most Americans get by on the BTS Skytrain, the MRT and Grab.

Can you drive on your US license?

Here's the simple version: a US license on its own isn't enough. Rental companies and police expect an International Driving Permit alongside it.

Getting an IDP before you leave

An IDP is a translation of your US license in a standard booklet. It's only valid with your actual license, and you must get it in the US before you go.

Who issues it: AAA is one of two organizations the State Department authorizes. AAA only issues IDPs to people with a valid US driver's license [1].
Cost: USD 20, plus photos. Online applications add a USD 10 photo fee and shipping [1].
Timing: Online takes about five business days plus shipping. AAA can't issue one more than six months before the date you want it to start [1].

An IDP is meant for visitors. Once you're a resident with a long-stay visa, plan on a Thai license. The DLT has also proposed that an IDP no longer counts as proof for the temporary Thai license, so don't rely on it as your way in [4].

Getting a Thai driver's license

In the US, moving states means a trip to the DMV. In Thailand, the DMV is the Department of Land Transport, and you book a slot through the DLT's online booking app [2].

What to bring

Passport with copies of the photo page, your current Non-Immigrant visa and your latest entry stamp [2].
Proof of address. Either your work permit, or a Certificate of Residence less than 30 days old [2]. Immigration issues residence certificates; at the Thailand Investment and Expat Services Center in Bangkok, for example, you apply with the form, a TM30 address receipt and your passport, and it takes about 15 days [6]. The page also says some embassies issue proof of residence.
Medical certificate from a Thai clinic or hospital on the standard form, less than a month old [2].
Your US license with copies, plus a certified translation or an IDP [2][3].

Tourist visas and visa-exempt entries generally don't qualify, however long you've been here [3].

The tests

Expect a short series of fitness checks (color vision, depth perception, peripheral vision and reaction time), a road safety video and a written theory test on Thai signs and right-of-way [2][3]. One 2025 guide puts the theory test at 50 questions with a 90% pass mark [2]. With a valid US license, the practical road test is often waived for a car, but some offices still ask for one, especially for motorbikes [3].

The rules here have been in flux. In June 2025, the DLT published a draft requiring foreigners with a foreign license to pass a written test, where they'd previously been exempt [4]. Requirements and renewals are set office by office, so call or check the DLT app first [3].

Fees and renewal

License	What you get	Rough fee [2]
First Thai license	Temporary, valid 2 years	About THB 205 for a car (about USD 6)
First renewal	5-year license	About THB 505 for a car (about USD 15)
Motorbike license	Separate license, same steps	About THB 105 to 205 (about USD 3 to 6)

These are figures from a November 2025 guide, not an official DLT fee table [2]. The medical certificate and any translation cost extra. Get the motorbike license at the same visit if you plan to ride.

Motorbikes: the real risk

Back home, a scooter is a beach-town rental. In Thailand it's how millions of people get around, and it's where the danger is.

The WHO estimates Thailand's road death rate at 25.4 per 100,000 people in 2021, ninth highest among 175 countries, or about 50 deaths a day. Motorcyclists accounted for 83.8% of those deaths [5].

If you ride anyway:

Wear a real helmet every time, and make your passenger wear one.
Get the motorbike license. Many travel and health insurance policies won't pay out if you crash without one.
Check your insurance. Ask in writing whether motorbike accidents are covered.
Be careful with motorbike taxis. The riders in orange vests are fast and handy for short hops down a soi (side street), but you're on the back with no protection.

Getting around Bangkok

Most Americans in central Bangkok don't drive. Traffic is famous for a reason, parking is scarce and the trains run above and below it.

BTS Skytrain and MRT

System	Lines	Paying
BTS Skytrain	Sukhumvit Line, Silom Line, Gold Line; about 70 km (43 miles) [7]	Rabbit card or single tickets; contactless bank cards not accepted as of 2026 [7]
MRT	Blue, Purple, Yellow and Pink lines [8]	Contactless credit and debit cards accepted on all four lines [8]
Airport Rail Link	Suvarnabhumi Airport to the city, connecting at Phaya Thai [7]	Tickets at the station

Fares on both systems go by distance [7][8]. The two networks connect at interchanges including Asok, Sala Daeng and Mo Chit, but they're separate systems: the Rabbit card works on the BTS, not the MRT [7]. So most people carry a Rabbit card and a contactless card.

Our full guide to the BTS, MRT and river boats in Bangkok covers lines, cards, the Chao Phraya river boats and how to get home late.

Grab, taxis and boats

Grab is Southeast Asia's version of Uber and the easiest ride-hail app here. It shows the price up front, lets you pay by card or cash, and does food delivery too.
Metered taxis are cheap by US standards. Insist on the meter.
Boats on the Chao Phraya river and the canals beat the traffic to the old city.

Should you drive at all?

If you live in central Bangkok and work near a train line, probably not. If you have kids at a school in the suburbs, live near Nichada Thani or plan road trips, a car makes sense. Get the Thai license sorted early and buy proper insurance.
