have you tried to Google it. You will find plenty. But I would not drive in Thailand unless you are a big risk taker and have very good insurance. The comments about Thais and tourists doing amazing things on the road in Thailand are true. They do not follow the road rules. But just Google anything you want to learn about Thailand and get a Thai sim card at the airport when you arrive. Transport is good from hire car and driver,bus, minivan, train and plane. Enjoy your holiday. If you have very good insurance for car and hospital cover then you can drive, but like many have said it is very different to driving in your home country.
