What are the requirements for renewing a Thai driving license as a resident with travel frequently?

I understand how confusing these processes can be. Here’s what I can confirm:

For the residence certificate, a TM30 is not sufficient on its own. You’ll need an official residence certificate from immigration or a yellow house book if you have one. The TM30 just proves you’re registered at a residence, but for the license renewal, immigration will need to issue the residence certificate.

You’ll also need:

• 2 photos

• A copy of your passport with visa and entry stamps (as you mentioned)

Regarding the house contract, this is not always required, but it’s good to have on hand in case they ask for further proof of residence. Since you’ve just done this in Pattaya for your dad, it sounds like you’re familiar with the process there.

90-day report: You’re right, if you travel frequently, you won’t have this, and it shouldn’t be a problem as long as your visa and TM30 are in order.

Appointment: You can go directly to the Department of Land Transport (DLT), but it’s highly recommended to make an appointment online. Walk-ins can lead to longer wait times or limited availability, especially if you’re in a busy location.

I had only TM30 from the hotel i was staying.

Suggest you make an appointment with DLT (need proof with QR code, otherwise you'll be waiting many hours. You can save time renewing by completing the multiple choice exam by doing it online showing DLT the QR code.

If you have car and bike license you’ll need two of everything Chonburi DLT accepted a copy and one original

Certificate of residence and medical need

You will need to make an appointment at the DLT.

Requirements are well defined in comments.

If you don’t have a long stay visa you’ll only get another two years.

Residents certificate needed from immigration

Here you go...

You need a medical certificate, a residence certificate issued by immigration (not a TM30) and your passport containing a long term non-immigrant visa/extension of stay. You'll need photocopies of anything you can't leave with them
