Which driving licence do I need in Thailand?

• Car — Both International Driving Permits are recognised: the 1949 Geneva model, valid one year and usable in the 101 countries party to that convention, and the 1968 Vienna model, valid three years and usable in the 84 countries party to it.
• Motorcycle — Thailand keeps entirely separate licence categories, and separate procedures for obtaining them, for cars on one side and motorcycles on the other, so a B licence alone does not let you ride a motorcycle there. Before leaving, it is recommended to have your international permit stamped for every A and A1 category you are entitled to: without the right category you risk fines and, after a crash, no insurance cover.

An International Driving Permit states the categories it covers: check yours covers what you will actually drive. A car licence does not cover a motorcycle, and a heavy camper or a truck can need a higher category.

At the wheel

• What insurance do I need to drive in Thailand? — No foreign policy is recognised, so you have to take out temporary cover at the border as you enter the country.
• Vehicle entry permit — Private vehicles need an entry authorisation issued by the Thai motor vehicle department, covering motorcycles, cars with up to 9 seats and vans up to 3,500 kg. Foreigners have to apply through a Thai travel agency, which gathers the documents, files them and then hands over the permit. Once all documents are in, the authorisation is issued within 30 days.
• Spare parts permit — Vehicle spare parts cannot be imported duty-free and need a permit from the Ministry of Industry.
• Fuel — Fuel supply difficulties may arise in Thailand, especially in outlying areas far from the larger cities, so take this into account when planning trips by car.
• Drive on the left — Traffic keeps to the left and overtakes on the right.
• What is the drink-driving limit in Thailand? — The blood alcohol limit is 0.05%, and rules on drink-driving were tightened on 1 June 2025. The same measures raised fines for riders and passengers caught without a helmet, even on very short trips, and stepped up checks and penalties for erratic driving, speeding and driving the wrong way.
• Are helmets and seatbelts compulsory in Thailand? — Helmets are compulsory for motorcyclists, and since 5 September 2022 seatbelts are compulsory in the rear seats as well as the front. Penalties for traffic offences are particularly steep.
• Scooters — The WHO places Thailand among the countries with the highest number of scooter and motorcycle riders killed on the road, an estimated 5,500 deaths a year, often because riders are not used to left-hand traffic and the traffic itself is chaotic. Scooters rented out by hotels and resorts are frequently unregistered and could not legally be ridden on public roads, so check the contract includes proper cover. Never leave your passport as security: leave a deposit instead.
• After a crash — If a crash involves other people you can face criminal consequences and be required to stay in the country until the local proceedings end. Before arriving, health insurance covering hospital stays after injuries and accidents, with an adequate ceiling, is strongly recommended, because hospital costs are very high.

What catches travellers out

• Land border stamp — Coming in overland, check that the Thai border officers actually stamp your passport. Travellers found without the stamp have had to go back to that crossing at their own expense before they could leave the country, and some were prosecuted for illegal entry and formally deported. Since 1 May 2025 every non-Thai traveller entering by air, land or sea must also complete the Thailand Digital Arrival Card online in the 72 hours before arrival and show the confirmation, which is not a visa; beware of fake TDAC sites.
• Visa-free stay — From 15 September 2026 Italian citizens get 30 days visa-free for tourism, extendable once by 30 days at an immigration office that decides case by case. At entry you must show a ticket out of Thailand within 60 days, and officers may ask for proof of funds, usually 20,000 THB in cash per traveller or 40,000 in cash per family. The exemption can be used at most twice in a calendar year. A visa is still needed for tourist stays of more than 30 days: it can be requested through the online e-Visa platform, ideally at least 15 days before arrival, and once it is approved you download and print the confirmation.
• Visa runs and overstaying — Leaving and re-entering the country within a few hours or days to get a new stay, a so-called visa run, is not allowed. Since November 2025 the authorities have announced stricter checks on anyone suspected of abusing the visa exemption to stay long in the country, with particular attention to those who use it for its full length and more than twice a year. Border officers have wide discretion over perceived visa runs, and a refusal of entry is not normally open to appeal. Overstaying is a criminal offence that can mean arrest, prison and formal deportation at your own cost.
• Passport condition — Your passport must be valid for at least 6 months on the day you enter and have at least two free pages for the entry stamp, and by law tourists must always carry the original. Under Thai immigration law a traveller without a travel document, or with one that is not intact and in good condition, is declared inadmissible to the kingdom, and the embassy cannot overturn a refusal at the border, so travel with a passport in perfect condition. Even minimal signs of wear could lead to a refusal of boarding when leaving Thailand, and border officers may treat souvenir stamps from tourist sites such as natural parks or archaeological sites as unauthorised tampering that invalidates the document and brings a ban on entry.
• Customs limits — Duty-free you may bring in at most one litre of alcoholic drinks and up to 200 cigarettes or 250 grams of cigars or tobacco; going over the limit means very heavy fines at the border crossing, which can lead to detention if not paid immediately. Firearms and ammunition need a special permit from the National Police, and information on bringing drones into Thailand is on the Italian embassy in Bangkok's website.
• E-cigarettes and cannabis — Possessing, using, selling, importing or exporting e-cigarettes and their parts is expressly forbidden, disposables included, and being caught is punishable by a fine of five times the item's value, to which a prison sentence may be added. Recreational cannabis remains illegal despite the 2022 medical legalisation, and since 26 June 2025 you need a medical prescription to buy cannabis even in licensed shops.
• Severe laws — Offences considered minor elsewhere generally bring immediate arrest and the start of a trial here, including theft of low-value items, small quantities of soft drugs and overstaying, and suspects are held in prison unless the judge sets a costly bail, with the passport kept by the police. Lèse-majesté under article 112 carries 3 to 15 years per count, cumulative, and can be applied to private remarks and social media posts, to insults to national symbols such as the flag and to political protest touching the monarchy. Even strongly negative online reviews of hotels or venues have occasionally brought defamation complaints.
• Hard drugs — The law on possessing and dealing hard drugs is very strict even for small doses: arrest is immediate when you are caught in the act, and the police run random urine tests. Penalties for dealing are extremely severe, and in the gravest cases local law provides for the death penalty.

Before you rely on this

This is our summary of advice written by the Italian Ministry of Foreign Affairs for Italian travellers, published on 22 September 2026. We summarise in good faith, but we cannot guarantee it is accurate, current or complete, and we take no responsibility for decisions made on the basis of it. Rules change without notice and are applied by officials at the border, not by websites. Always read the original source and the travel advice your own government publishes for Thailand before you travel. Where a guide's profile shows “Licence verified”, we found that licence in the official public register; otherwise GuideMeet has no way of checking whether an individual guide meets any standard mentioned here — ask them directly.
