Your Travel Guide to Thailand
All information & tips to prepare your trip in Thailand
The roads in Thailand are generally of good quality. Especially in major cities like Bangkok, Chiang Mai, and Phuket, the main roads are well-maintained and paved. Highways and main roads (national roads) are in good condition and well-marked.
However, in rural areas and mountainous regions, roads can be in poor condition, with potholes and unpaved sections, even ending in dirt roads for the most remote corners. There are some areas where a 4x4 is indispensable. So, make sure to get proper information before venturing too far off the beaten path! Secondary roads can also be more challenging to navigate. Another important point, during the rainy season, torrential downpours can make traction very difficult and greatly reduce visibility (it's better to stop as soon as possible in a safe place and wait for the storm to pass). There can also be floods and occasional landslides.
Unfortunately, Thailand is known for having one of the highest road accident rates in the world. According to the World Health Organization (WHO), the Siam Routes regularly rank in the Top 10 most deadly roads in the world and the deadliest in ASEAN with a road mortality rate of 32.7 per 100,000 inhabitants in 2018, for example. This statistic places Thailand among the countries with the most dangerous roads in the world.
The main causes of accidents include:
It is important to note that deaths and injuries on the Siam Routes are mainly among people riding motorcycles or scooters. They represent 3/4 of the road victims in Thailand. That's why if you want to get around on your own during your trip to Thailand, I recommend renting a car rather than a scooter or motorcycle.

The driving rules, I am not talking about the traffic code in Thailand but those that apply on Siamese roads, are quite different from ours. And it's not just because in Thailand, you drive on the left but also due to a management, for example, of priorities and overtaking that is nothing like what is done in Europe. Here are some basic rules to know before driving in Thailand:
Renting a car in Thailand is relatively simple. And as I said, it is certainly more expensive than renting a scooter, but it's safer. Fatal accidents are much rarer and moreover, the requirements for renting a car in Thailand for a tourist and driving legally and covered by insurance are simpler than for a scooter (see my article on renting a scooter in Thailand). You can book your vehicle online via sites like Rentalcars.com or at car rental agencies located at airports and in major cities. Here are some important points to consider:
Driving in Thailand can be an enriching experience, giving you the freedom to discover less touristy places at your own pace, creating a customized trip to Thailand by going off the beaten path. However, it is crucial to be well-prepared and to stay vigilant to fully enjoy your stay safely.
By following these tips and being aware of potential challenges, you will be able to explore the Siam Routes with peace of mind and discover the wonders that Thailand has to offer.
