Your Travel Guide to Thailand
All information & tips to prepare your trip in Thailand
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 signposted.
However, in rural and mountainous areas, roads can be in poor condition, with potholes and unpaved sections, even turning into dirt tracks in the most remote corners. In some areas, a 4x4 is essential, so make sure you get proper information before venturing too far off the beaten track! Secondary roads can also be more difficult to drive on. Another important point: during the rainy season, torrential downpours can make the roads very slippery and greatly reduce visibility (it's best 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 among the 10 deadliest in the world and are the deadliest in ASEAN, with a road death rate of 32.7 per 100,000 inhabitants in 2018, for example.
The main causes of accidents include:
It is important to note that deaths and injuries on the Siam Routes mainly involve motorcycle and scooter riders, who account for 3/4 of 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 rules of the road – I don't mean the official traffic code, but the way people actually drive on Thai roads – are quite different from what you may be used to. And not just because in Thailand, you drive on the left, but also because of the way priorities and overtaking work, which is nothing like what you see in Europe or North America. Here are some basic rules to know before driving in Thailand:
Renting a car in Thailand is relatively simple. As I said, it is certainly more expensive than renting a scooter, but it's safer: fatal accidents are much rarer and, what's more, the requirements for a tourist to rent a car and drive legally with insurance cover are simpler than for a scooter (see my article on renting a scooter in Thailand, in French). You can book a vehicle online on sites like Rentalcars.com or at car rental agencies at airports and in major cities. Here are some important points to consider:
Driving in Thailand can be a rewarding experience, giving you the freedom to discover less touristy places at your own pace and create a tailor-made trip to Thailand off the beaten track. However, it is crucial to be well prepared and to stay alert so you can fully enjoy your stay safely.
By following these tips and being aware of the potential challenges, you will be able to explore the Siam Routes with peace of mind and discover the wonders the country has to offer.
