not quite true. If you get your international driver’s license before you leave your home country it needs to state that you have both car and motorcycle licenses to get both here in Thailand otherwise you’ll only be allowed the one that you have in your home country.
Thailand has recently said that they are looking into travel bubbles between them and countries that are managing well with Covid and have also started rolling out the vaccine but this will take time and for the moment it’s a 15 night 16 day quarantine. I can’t see anything changing until at least the end of the year. I hope it is sooner.
