How can I obtain a temporary motorcycle license in Thailand with a tourist visa?

Do you hold a MC licence in your own country? Get an International Driving Permit from your national motoring association. If you don't have a MC licence and rent a MC in Thailand, ensure your travel insurance has an "idiot" provision.

For real i just rented a bike with copy of passport and rode if they stop you it will be because you dont have a helmet or they want a bribe. They didnt even ask me for any license just told me i had to goto court to somewhere down the road and it would take about 4 hours and i asked if i could just accept guilt and pay them now and they took me into a building and scared shit out of me thinking OMG i just bribed him now he is taking me in here to beat me and arrest me to put in thai jail but he just wanted the cash without his coqorkers seeing then he told me to go and i drove away with my helmet which is what i was stoppex for no helmet i had in though but dealer who rented to me said no need helmet up to me and i sa2 thai not wearing so i thought good to go but they had traffic roadblick and told me to pull over and asked why i wasnt wearing helmet and it 2as illegal and to go to court for 4 hours . Someone had told me to just offer to pay them that they just want a bribe and it worked . So my take is just rent n ride if stopped ask them can you just pay them fine right now to them and they will gladly accept and send you on your way. No probl3m.

get a i d p from post office only a fiver

Get a international driver’s license from RAA

Interaction with the local police is the least of your issues if unlicensed. When you ride a scooter (or whatever) without a licence, whatever form of insurance you might have bought (like travel insurance or local health insurance) will not cover you when you have an accident. You are breaking the law so the insurance company has an instant "out". This lack of coverage includes the deductible/excess on the vehicle, damage to other people/vehicles/things and your own medical bills. You will be yet another GoFundMe page that is pleading for donations. Please don't put yourself in this situation. Don't listen to all these brave souls that tell you they have been driving/riding for 300 years without a licence. Get the right licence and travel insurance at home.

I dont know Chiang Mai so well but every other place, the police are predictable. They set-up shop at the same locations at the same times and the locals know this. They mostly get the tourists who do not know. The ticket/bribe/tea money is 500 baht ($15).

I have been driving in Thailand about 8 or 9 years and I have never had a proper license. Even if you do have a proper license, the system is set-up so that its easier to pay than it is to be in the right. It's just generally understood.

If you feel the need you can get a IDP but I have found those are useless, in Thailand, Australia and US, they don't have much meaning. If you can produce an actual license in any country then its understood that you have a license in some other country, which is all the IDP states.

International driving licenze and u are ok

If you're just coming as a tourist for month or two just make sure you have an IDP from your home country covering you for scooters and your good to go

You’re not going to get the “residence certificate” that’s needed for a license in Bangkok. They only issue those for people who’ve done a 90 day report, which you can’t do on a short term visa or exempt entry.

Not 100% sure of the policy in CM. You probably can get one on a tourist visa or even an exempt entry. I’ll let others with direct experience confirm.

Make sure you have an international driving permit with your motorcycle endorsement. For 30 days, that's all you'll need. AAA will provide them.

There's no such thing as a 30 day tourist visa. The only way to get a tourist visa is to apply for and pay for one from a Thai embassy before you travel.

If you go without a visa you'll receive 30 days visa exempt.

Neither of these will allow you to get a certificate of residency in Bangkok which you'll need for a drivers license.

Chiang Mai will be possible if you pay 500₿ for "expedited service" and have a TM30 from where you're staying.

I'm not sure if you can get a license on visa exempt though. You might need to be on a tourist visa to do so.
