Renting a Car in Thailand
A rental car lets you explore Thailand at your own pace, including places that buses and trains do not reach easily. It also brings responsibilities: traffic drives on the left, the paperwork rules are strict, and since April 2026 the police issue fines instead of warnings.
Here is what to know before you rent a car, and when a car with a driver is simpler.
Licence Requirements
International Driving Permit (IDP)
Visitors must carry two documents while driving: an International Driving Permit (IDP) and their home driving licence. The IDP is only valid together with a valid home licence, so always keep both with you.
- Get the IDP in your home country before you travel. The UK government specifies the 1968-convention IDP, which UK drivers must buy before leaving.
- The IDP must show the right vehicle class. A car-only IDP does not cover motorbikes (including scooters).
What Happens Without an IDP
Driving on a home licence alone can void both the rental car's insurance and your travel insurance, so you could have to pay for any damage yourself. A 2026 rental guide gives a fine of up to 2,000 THB for driving without an IDP.
Where to Rent
At Suvarnabhumi Airport (BKK), the self-drive car rental counters are on Level 2, Gate 7, in the main terminal. Two Thai options are also worth knowing:
- Haupcar is a Thai car-sharing and rental platform with over 1,000 pickup points, including Suvarnabhumi and Don Mueang airports, Chiang Mai, Phuket, Pattaya, Krabi, Khon Kaen and Hat Yai. It rents cars and vans, some with a driver. Website: Haupcar.
- EVme is the electric-car rental company of the PTT group (phone 02 028 2688). Website: EVme.
Insurance and Checks at Pickup
Before you sign, ask at the counter:
- What does the insurance cover, and how much do I pay myself if the car is damaged?
- Which fuel does the car take?
- How are M-Flow motorway tolls billed?
- Which number do I call after a breakdown or an accident?
Before you drive away, walk around the car and photograph every scratch and dent, including the wheels and the windscreen. Make sure existing damage is written on the rental form.
Traffic Rules and Fines in 2026
Thailand drives on the left, and the steering wheel is on the right.
A warning period ran from January to March 2026. From 1 April 2026, police issue fines instead of warnings, so assume every rule below is enforced.
Speed Limits
The default speed limits for cars are:
- 80 km/h in built-up areas
- 90 km/h outside built-up areas (some highways allow more; the signs show it)
- 120 km/h on motorways
Signs can also set lower limits locally, so always follow the posted sign. Motorbikes are not allowed on motorways.
Alcohol
The blood-alcohol limit is 0.05%. For drivers under 20 or holding a temporary licence, it is 0.02%. The safest rule is simple: do not drink at all if you are driving.
A first drink-driving offence can mean up to 1 year in prison and/or a fine of 5,000–20,000 THB, and a licence suspension of at least 6 months. Refusing the test carries the same penalty.
Seatbelts and Child Seats
Everyone in the car must wear a seatbelt, including passengers in the back seats (Road Traffic Act No. 13, 2022). The fine is up to 2,000 THB.
Children under 6 must ride in a child seat, and passengers under 135 cm need a seatbelt or a special seat. This has been enforced since 17 August 2023 (up to 2,000 THB), so book a child seat with the car or bring your own. Public vehicles such as buses, public vans and taxis are exempt from this rule.
Fines and Demerit Points
These are the maximum fines in 2026 for common offences:
| Offence | Maximum fine |
|---|---|
| Speeding | 4,000 THB |
| Running a red light | 4,000 THB |
| Not stopping at a pedestrian crossing | 4,000 THB |
| Driving the wrong way | 2,000 THB |
| No seatbelt or no helmet | 2,000 THB |
Holding a phone while driving is also an offence; sources disagree on the fine.
Thailand also uses demerit points. Every licence holder starts with 12 points, and losing all of them within a year means a 90-day suspension. Speeding, no seatbelt or helmet, and phone use cost 1 point each; running a red light or driving the wrong way costs 2; drink-driving costs 4.
Tolls and Fuel
M-Flow Tolls: No Booths
Some motorways now use M-Flow, a barrier-free toll system: there are no booths, and cameras read the number plate. M-Flow operates on Motorway 9 (the outer ring road) and, since 16 January 2026, on Motorway 81 (Bang Yai–Kanchanaburi). Motorway 7 (Bangkok–Pattaya) and Motorway 6 (Bang Pa-in–Nakhon Ratchasima) are expected to follow, so watch the signs at each toll point.
M-Flow tolls must be paid within 7 days, on the M-Flow website or app, or through an Easy Pass Plus account. Late payment costs 10 times the toll plus 200 THB, so ask the rental company how it handles M-Flow bills before you drive.
Fuel Prices
PTT fuel prices in Bangkok from 24 September 2026:
| Fuel | Price per litre |
|---|---|
| Gasohol 95 | 39.94 THB |
| Gasohol 91 | 39.57 THB |
| Gasohol E20 | 34.94 THB |
| Diesel | 41.44 THB |
| Diesel B20 | 36.44 THB |
| Benzine (petrol without ethanol) | 48.93 THB |
| Super Power Gasohol 95 (premium) | 47.79 THB |
Fuel prices change often. The third-party prices, fines and rules in this article were checked in September 2026; confirm them with the rental company or the operator before you travel.
Renting a Motorbike or Scooter
In this section, "motorbike" also means a scooter. The rules are stricter than many visitors expect:
- Licence: you need a home motorcycle licence plus an IDP that shows the motorcycle class. A car licence does not cover a motorbike. Police check licences at roadside checkpoints, and travel insurance may refuse to pay for an unlicensed rider.
- Helmets: compulsory for the rider and the passenger. Since 1 June 2025 police enforce this with fines of up to 2,000 THB, doubled for a rider who carries a passenger without a helmet.
- Registration: many hire motorbikes in tourist areas are unregistered and cannot legally be ridden on public roads. Ask to see the registration before you rent.
- Deposit: never leave your passport as a deposit with a motorbike or jet-ski renter. Offer a copy of your passport and a cash deposit instead.
The UK government's Thailand safety and security advice covers these risks in more detail.
If Something Goes Wrong
After an accident, stop and do not leave the scene. Call for help first, then the rental company. Take photos of the vehicles, the road and the other car's number plate.
| Service | Number |
|---|---|
| Police | 191 |
| Ambulance | 1669 |
| Fire | 199 |
| Tourist Police (24 hours) | 1155 |
| Highway Police (24 hours) | 1193 |
The "Thailand Tourist Police" app lets you contact the Tourist Police online without a Thai SIM card.

When a Driver Makes More Sense
A rental car is not always the best choice: after a long flight, in Bangkok traffic, or on an evening when you want a drink with dinner, a driver is simpler.
Smile Taxi Service offers private transfers at fixed prices per vehicle, one way, with expressway tolls included. For example, from Suvarnabhumi Airport to Pattaya a sedan costs 1,200 THB, an SUV 1,500 THB and a van 1,800 THB: book a sedan from Suvarnabhumi to Pattaya. Airport pickups include 60 minutes of free waiting, counted from the actual landing time. A child seat costs +100 THB on request, and an English-speaking driver can be requested when booking, subject to availability. You pay the driver in cash (THB) at the end of the trip; if you can only pay by card, message the team for a PayPal payment link (a 5% fee is added). Cancellation is free up to 24 hours before pickup. After that, a cancellation or change costs 25% (less than 24 h), 35% (less than 12 h) or 50% (less than 2 h) of the price, and a no-show 100%, also when you pay the driver in cash (details).
For a day of sightseeing, a full-day private tour (up to 10 hours) gives you a car and driver. The Bangkok Tour costs 2,700 THB by sedan, 3,000 THB by SUV, 3,700 THB by van and 4,000 THB by VIP van. See tours and day trips or all routes and prices. For the public transport options on popular routes, read how to get from Bangkok to Pattaya and how to get from Bangkok to Khao Yai.
FAQ
Can I drive in Thailand on my home licence alone? No. Carry an International Driving Permit together with your home licence. Without an IDP you risk a fine (up to 2,000 THB according to a 2026 rental guide) and your insurance may not pay.
Does my car IDP let me ride a motorbike or scooter? No. You need a home motorcycle licence and an IDP that shows the motorcycle class.
How do I pay tolls on motorways without booths? M-Flow reads your number plate. Pay within 7 days on the M-Flow website or app, or through Easy Pass Plus, or you pay 10 times the toll plus 200 THB. With a rental car, ask the company how it bills these tolls.
How much is petrol in Thailand? In the PTT prices for Bangkok from 24 September 2026, Gasohol 95 is about 40 THB a litre and diesel about 41 THB. Prices change often.
What is the drink-driving limit? 0.05%, or 0.02% for drivers under 20 and holders of a temporary licence. A first offence can mean a fine of 5,000–20,000 THB and/or up to 1 year in prison, so do not drink at all if you are driving.
