A foreigner can drive a car or motorcycle in Thailand using an international driving permit. However for long term residents it is necessary to acquire a Thai driving license. This is automatically issued to those carrying an international driving permit , you will also require proof of address(obtained from the local immigration police), a medical certificate and your passport along with recent passport photographs. If you do not have an international driving permit then you will require all of the above and have to sit a written and practical test. We can arrange appointments for you to meet with the local transportation office and assist you in obtaining the necessary documentation.
