What type of visa do I need to renew my Thai motorbike license?

Unfortunately I'm not seeing in the least how getting a thai drivers license is related at all to Thai Visa Advice :O

You can get a 2 year temporary Thai drivers license on ANY type of entry to thailand as long as you have proof of residence and a medical certificate. Makes no difference if you're on a 30 day visa exempt entry, a 15 day visa on arrival, a 60 day tourist visa, a 90 day Non-Immigrant visa or any type of extension on those things.

I think we're done :/ sorry people

I'm also interested in this (and have been trying to chat with a couple of visa agencies in CM about it recently). As far as I can tell, although

@Robert ******

seems to be correct from the perspective of the Department of Land Transport, the main sticking point seems to be getting the residence certificate on a short-term stay/visa-exempt entry (at least in CM - I know some immigration offices elsewhere are perhaps more flexible).

One of the visa agencies in CM told me today that it's necessary to have a visa of "more than 30 days" to get the residence certificate (their words, not mine - some info may have been lost in translation), and I've read elsewhere about generally needing an apartment contract longer than 3 months. So this might be the real issue for renewing a licence during a short-term stay. I haven't yet been able to figure out whether there's a solution to that?

(My situation is that my first two-year Thai licence expired a couple of months ago and I'd like to renew it so I can drive legally while I'm visiting CM next month for a couple of weeks on an exemption (or SETV, if necessary)).

It's also possible to get a license in Vietnam which doesn't expire and is valid across asean

You can renew your driving license on every visa or visa exempt entry. If you're inside Thailand using Visa Exempt or Toursit Visa you will get "temporary" driving license which is valid for 2 years.
