What is the updated procedure to renew a Thai driver's license in Bangkok?

To renew your Thai driver's license in Bangkok, you'll need to prepare several documents: your original and a copy of your passport, a medical certificate (recommended even if not always needed for licenses over 5 years), a copy of your visa, and a copy and original of your work permit or proof of residence. You can go to the Chatuchak main office without an appointment, typically arriving around 7:30 AM. Be prepared for a likely queue, as appointments can fill up quickly—one user reported waiting until late March for a time slot. Renewal may require attending a video class, a physical examination, and a doctor's certificate. The entire process can take over six weeks. Determining your specific transport office's requirements can influence wait times.
