i have a accident with a car many years back, i am cycling and the car turn left and i flew on top of his car. rescue workers came, told them i will go hospital by myself after going to the police station. officer say i can go private hospital, but the insurance will not pay doctor's fees. i pay, than go to the car driver's insurance company to file a report. they paid..
thai's first aid is manage by which ever rescue group (unpaid workers and money are donated by people who they have help etc.) that operates in the area that you are in. they will take you to the nearest hospital. if you want nice hospitals like bumrungrand etc, you have to call them to arrange a private ambulance to pick u up.
go to the 2nd floor of mfa near cheng wattana mrt station, there is a translation shop, after they are done, go to the mfa, they can post it back to you by ems, just pay extra.
