Where can I obtain an International Driving Permit to use my Thai license in Vietnam?

To obtain an International Driving Permit (IDP) in Thailand, you must have a valid 5-year Thai driving license. You can apply for the IDP at a Department of Land Transport (DLT) office. However, if you possess only a 2-year Thai license, it is generally considered temporary and may not be recognized for driving in other ASEAN countries, including Vietnam. Despite this, Vietnam recognizes domestic driving licenses issued by ASEAN countries through an agreement, so your Thai license may be valid. Ensure to check with car insurance providers for their requirements regarding driving in Vietnam.
