I attempted to renew my driver's license back in August and it was not done then. I was advised that I needed to provide the following as per the handwritten text from the personnel at the driver's license center east of Bangkok:
Passport + visa + certificate of residence from the embassy or immigration + medical certificate
Or:
Pink card + yellow book + medical certificate
And I was advised to do online training at https://www.dlt-elearning.com/forignerhome. Once you have completed that training session, you would need to print the QR code and bring it with you or do it on your mobile phone and log in to that site and show the QR code.
And I was issued with an appointment for November 1, 2022 on that day back in August.
I suspect if the OP has none of the above, he will be advised to provide the documentation as noted above and an appointment date will likely be issued.
