Rules for overlanding in Thailand

Our summary of the country advice published by the Italian Ministry of Foreign Affairs (Viaggiare Sicuri) on 3 September 2026.

Which licence you need

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, 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

Insurance — 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.
Drive on the left — Traffic keeps to the left and overtakes on the right.
Alcohol and 2025 crackdown — 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.
Helmets and belts — 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, around 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 cash 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.

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 everyone 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 per traveller or 40,000 per family. The exemption can be used at most twice in a calendar year, border officers have wide discretion over suspected visa runs, and overstaying is a criminal offence that can mean arrest, prison and deportation at your own cost.
E-cigarettes and cannabis — Possessing, using, selling, importing or exporting e-cigarettes and their parts is expressly forbidden, disposables included, and being caught brings a fine of five times the item's value plus possible imprisonment. 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 bring immediate arrest and 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 applies 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.
