Are you planning your dream holiday to Thailand? Wonderful! It’s a country that has stolen the hearts of millions, including ours. But before you start booking flights and packing your bags for this trip to Thailand, you probably have plenty of questions swirling in your head. What are the key attractions, what currency should you use, what’s the weather like at a given time, and what’s the time difference? And most importantly, the thing that keeps you up at night: is it safe in Thailand, and how do you cope with the fact that Thailand has left-hand traffic? This thought can be paralysing, especially if you’re planning an independent holiday rather than an organised all-inclusive trip. Don’t worry! We’ve prepared a complete guide for you, which is a treasure trove of knowledge for anyone planning a trip to Thailand. Whether it’s a last-minute trip or a carefully planned 14-day journey, with us, you’ll find out what’s worth knowing. We’ll explain the approximate cost of a trip to Thailand, what affects the price of a flight ticket, and how to make sure your adventure of a lifetime doesn’t break the bank. This is essential advice that will make you feel confident and comfortable in the Land of Smiles.

Where on earth did the idea for left-hand traffic come from?

Before we jump behind the wheel in Bangkok, it’s fun to satisfy our curiosity. Why exactly do nearly a quarter of the world’s countries, some 78 nations, stubbornly drive ‘against the flow’? Because it’s no accident at all, but a fascinating journey through history, conquests, and cultural quirks that will explain why driving on the left is the norm in so many places around the world.

From knights with swords to the British Empire

Where did this idea for left-hand traffic come from? Well, we need to go back to ancient and medieval times. In those days, roads were primarily used by horseback riders. For most people, who were right-handed, keeping to the left side was simply logical and safer. They held the reins in their left hand, while their right, stronger hand, remained free. They could use it to greet a friend, or – more importantly – draw a sword for defence against someone approaching from the opposite direction. Some sources even mention an edict by Pope Boniface VIII from 1300, who is said to have ordered pilgrims to keep to the left, but the real global exporter of this rule only became the British Empire. As Great Britain grew in power and conquered further territories, it instilled its law and customs there. And so, left-hand traffic became firmly rooted in its numerous colonies for good.

How Napoleon and France switched Europe to the right side

If the British preferred the left side, then who do we owe the right-hand traffic to that dominates most of Europe today? Here, France enters the stage, and, of course, Napoleon Bonaparte himself. There are several theories. One, quite a colourful one, says that before the French Revolution, the aristocracy drove on the left, pushing the poor onto the right side. After the revolution, as a gesture of rebellion, everyone started driving on the right. Napoleon himself, being left-handed, is said to have preferred the right side to better observe his troops. With his conquests, right-hand traffic spread across a significant part of the continent, including areas of the Netherlands, Germany, Switzerland, and Poland. Former French colonies also still drive on the right today. Interestingly, even in areas Napoleon never conquered, like Austria-Hungary, left-hand traffic persisted until the state’s collapse, and in Austria, Czechoslovakia, and Hungary itself, changes were introduced gradually, often under pressure from the Third Reich. And in our Austrian partition? In Krakow, trams switched to the right side only in 1925.

Who else drives ‘against the flow’ and why? The mysteries of Japan, Indonesia, and Thailand

Although most countries with left-hand traffic are former British colonies, there are also intriguing exceptions. The most famous is Japan, which was never under British rule. There, the tradition of driving on the left dates back to the 17th century and the era of the samurai. They wore their swords on the left side, so they needed space to draw them freely when passing others. This custom was codified by decree in 1872, when the first railway line was built with British assistance. Another interesting case is Indonesia, although in many similar cases, the key is colonial history. Here, the puzzle is the Netherlands. The Dutch originally drove on the left, so they introduced this custom in their colony. When Napoleon conquered their country and forced them to switch to right-hand traffic, Indonesia and other Dutch colonies, like Guyana and Suriname, stuck to the old rules. And that’s how they still drive today.

Currently, left-hand traffic is still in force in 78 countries. In Europe, these are only four islands: Great Britain, Ireland, Malta, and Cyprus. Outside our continent, the list is long and includes, among others, Australia, New Zealand, India, South Africa, Kenya, Malaysia, and Singapore. And of course – our protagonist, Thailand. It joined this group without explicit ties to Great Britain, most likely under the influence of neighbours and British advisors who helped modernise the country in the 19th century.

Navigating Thai traffic chaos: Can you get a handle on it?

Alright, enough theory, time for practice. The thought of driving on Thai roads alone can make your heart beat faster. Remember, left-hand traffic isn’t just a matter of keeping to the other side of the road. It’s the necessity of developing completely new habits to make driving a joy, not a stress. But don’t worry, with our tips, you’ll quickly get into the swing of things.

Your first moments behind the wheel: practical tips to get started

The first impression after getting into a car with the steering wheel on the right is… strange, to say the least. A mirror image. The steering wheel is on the right, and the gear stick (in a manual, if you encounter one) is operated with your left hand. Give yourself a moment to get used to this in the car park. Check where the indicators and windscreen wipers are – they are often swapped (which leads to comical situations when you’re trying to turn in the rain). Your new point of reference becomes the left edge of the road and the central line, which must now always be on your right side. It’s also worth knowing that the dipped headlights in such cars are asymmetrical and directed to illuminate the left side, not to dazzle oncoming traffic.

Junctions, roundabouts, and the unwritten rules of the Thai street

This is probably the hardest part. At uncontrolled junctions, the rule is the opposite of ours – theoretically, vehicles from the right have priority. But that’s the theory. In practice, especially in Thailand, the ‘bigger vehicle has priority’ rule reigns supreme. Or rather, it’s not so much a rule as a brutal reality. The biggest challenge, however, is roundabouts. Remember: you enter a roundabout by turning left, and move clockwise. Those already on it have priority.

Official rules are one thing, but life is another. As my friend, who has lived in Bangkok for years, says: “There are no rules here, only suggestions”. The most important rule: keep your eyes peeled and expect the unexpected. Using the horn isn’t a sign of aggression here, but rather a message like ‘watch out, I’m coming!’. Feel free to use it, but briefly. Give way to buses and lorries, and watch out for the countless scooters and motorbikes that appear out of nowhere and squeeze into every gap. Unfortunately, you also need to remember the risk posed by drunk drivers, so the principle of limited trust is your road safety motto.

Car and scooter hire: How not to get ripped off?

Hiring a vehicle is a great idea (and honestly, probably the best way to explore the country), but it requires caution. Choose reputable hire companies. Read the contract carefully, especially the insurance clauses. And most importantly – before you drive off, take detailed photos and videos documenting all existing scratches, dents, and the condition of the tyres. This will protect you from attempts to extort money for damage you didn’t cause. Check the brakes, lights, horn, and find out the current price of fuel to plan your budget. Also, make sure you have an International Driving Permit – it’s absolutely essential.

Safety off the road: potential dangers in Thailand

Thailand is generally a safe country, and its locals are incredibly friendly. However, as in any tourist destination, you need to be vigilant. Awareness of potential pitfalls will help you avoid trouble. Before you travel, it’s always worth checking the advice from the British Embassy in Bangkok and the FCDO (Foreign, Commonwealth & Development Office).

Scams, touts, and transport: how to travel cheaply and wisely

Plenty of traps await tourists. Watch out for touts who will try to convince you that the temple you’re going to is currently “closed to tourists”, but they’d be happy to take you to another, “better” one. This usually ends with a visit to a friendly shop where gold prices are inflated, or to a tailor. Another trick is selling fake gemstones. Always count your change, as some vendors might try to rip you off by quoting a higher price for souvenirs or even a bottle of beer. It’s also worth knowing the local realities, e.g., the approximate price of cigarettes, so you don’t overpay. And how to travel and what mode of transport to choose? The safest option is a licensed taxi with a meter. A tuk-tuk is a great adventure, but always agree the price with the driver before starting the journey, otherwise, an unpleasant surprise awaits you at the end. If a driver offers a suspiciously low price, they probably want to take you on a shopping tour. For longer distances, trains, buses, and budget airlines are great. Only buy tickets from official ticket offices, never from street touts.

Law and order: drugs and insulting the King are no joke

This is extremely important. Thai law is ruthless on two matters: drugs and the monarchy. Possession of even the smallest amount of drugs can lead to many years in prison, and trafficking can even result in the death penalty. There have been instances of provocation where police officers planted drugs on tourists and then demanded high bribes. Never take anything from strangers and keep an eye on your drinks.

The second sacred thing is the King and the entire royal family. Any lèse-majesté – an unfavourable comment, damaging a banknote with the King’s image, or even criticism online – is a crime punishable by severe imprisonment. It was widely reported that a man was sentenced for insulting… the King’s dog. So, on this matter, the rule is simple: speak about the royal family with respect, or not at all.

Longer stays and travel under special circumstances

What if you’re planning to move to Thailand permanently or at least for a longer period? It’s worth checking in advance what visa is needed and what formalities must be completed. A long-term stay is also associated with other costs, such as the price of an apartment or even a house. When planning a trip to Thailand with a child, remember to consider additional facilities and appropriate insurance. Travelling to Thailand while pregnant requires consulting a doctor, and travelling to Thailand with a dog is a complicated logistical operation, requiring numerous permits and veterinary checks.

Safety after dark: clubs, beaches, and falling coconuts

After dark, especially in resorts, petty thieves become active, targeting wallets and smartphones. In nightclubs, don’t leave your drinks unattended. Women travelling solo should avoid walking alone down deserted streets after dark. Even on the paradise beaches of Thailand, you need to be vigilant – don’t leave valuables on your towel when going for a swim. And one more thing, though it sounds like a joke: watch out for the forces of nature and don’t walk under palm trees. Falling coconuts really can cause injury.

Health in the tropics: how to eat and stay well

An exotic trip is a challenge for the body. Different bacterial flora, scorching sun, and mosquitoes require preparation. Taking care of your health is essential to ensure tummy troubles don’t spoil your holiday.

The Flavours of Thailand: Is street food safe?

Thai cuisine is poetry! It’s healthy, delicious, and often very spicy. Bangkok is famous for its brilliant street food. Don’t be afraid of it, but be smart about it. Choose stalls where there’s a crowd of locals – that’s a guarantee of freshness. Avoid dishes that look like they’ve been sitting around for a long time. Stale food or water from an unknown source is a direct route to diarrhoea, and in worse cases, even hepatitis infection. And if you’re not a fan of spicy food, always ask for a milder version (‘mai pet’). An interesting point is durian – a fruit with a divine taste and… a smell that knocks you sideways. It’s so ‘aromatic’ that bringing it into hotels is forbidden.

Vaccinations and other health issues: what you need to know before you fly?

A key issue to be aware of before travelling is health. Are you wondering what vaccinations are needed for Thailand? Before your trip, ideally 4-6 weeks in advance, you must visit a travel doctor or clinic to discuss recommended vaccinations. There are no compulsory vaccinations, but there are several recommended ones that will give you peace of mind. The most important ones are against:

• Hepatitis A (a ‘dirty hands’ disease).
• Hepatitis B (transmitted through blood).
• Diphtheria and Tetanus (DT) and Measles, Mumps, and Rubella (MMR) – it’s worth checking they are up to date.
• Typhoid – also transmitted through food and water.
• Rabies – if you plan contact with animals.
• Japanese Encephalitis – especially if you are going to rural areas.

What about malaria? The risk is low and confined to forested areas near the borders with Cambodia, Myanmar, and Laos. In popular places like Bangkok, Phuket, or Koh Samui, it’s practically zero.

Water, ice, fruit, and sun protection

The golden rule in the tropics: only drink bottled water that’s originally sealed. Use it to brush your teeth too. Ice in drinks? In reputable establishments, it’s safe, made from purified water (it’s tube-shaped with a hole in the middle). Wash fruit and vegetables in bottled water or peel them. And most importantly – wash your hands often. When you can’t, have antibacterial gel with you. It’s a simple thing that protects against many illnesses.

The tropical sun can be relentless. So, what to pack in your travel first-aid kit? The absolute essentials are high-factor sun cream (SPF 30-50), a hat, and sunglasses. Also protect yourself from mosquitoes, which can carry dengue fever. Use repellents with a high DEET content, especially at sunrise and sunset.

Natural forces and the country’s situation: is there anything to be afraid of?

Thailand is located in a region where nature can be unpredictable, and politics can be dynamic. But is there really anything to fear? Awareness of potential risks is key to peace of mind.

Many people associate this country with the tragic tsunami of 2004, which devastated Phuket and Khao Lak, among other places. This tragedy, depicted in the film ‘The Impossible’, led to the creation of a modern early warning system. Today, you’ll find signs for evacuation routes on the beaches. A more realistic threat is seasonal flooding during the rainy season. As for politics, it can be unstable. In the past, there have been demonstrations and civil unrest, and isolated terrorist attacks have occurred. Tourists are rarely the target, but the British Embassy and FCDO advise avoiding all demonstrations and remaining vigilant.

Your guardian angel abroad: the Embassy and staying informed

Before every trip, especially one so far away, the Foreign, Commonwealth & Development Office (FCDO) encourages travellers to stay informed and register their trip details. This free registration of your journey where you provide your details, could literally save your life. In case of a natural disaster or other crisis, the consul will know you are there and can quickly contact you. Also save the number and address of the British Embassy in Bangkok. It’s your point of contact in case you lose your passport or have other serious problems.

Ready for the road and adventure? Your final preparation before you fly

Your trip to Thailand is almost within reach! Your head is full of images of paradise beaches, exotic temples, and the smell of street food. To ensure nothing spoils this idyll, it’s worth calmly going through the final checklist. Good preparation is the foundation of a successful trip, regardless of whether it’s your first trip to Thailand or another tour around the country. If you’re looking for more inspiration, plenty of travel blogs offer ready-made itineraries and advice. For those who value convenience, organised tours are a great option. I remember feeling a mix of excitement and slight fear before my first trip to Southeast Asia – that’s completely normal! But with the knowledge you now have, you’re ready for anything. The Land of Smiles awaits!
