there are almost no rules when driving in Thailand. you can drive on the other side of the road if you like but must get out of the way of on coming traffic. but there is not a lot of cars on the road and everybody drives the same as everyone else so there are not a lot of accidents on the road. they don't have people speeding at a 100 miles an hour over here and no road rage. Everyone knows what to do. if someone honks there horn at you there not saying "YOU IDIOT GET OUT OF THE WAY". they are saying that they are concerned about your safety and do not want you or anyone else to get hurt. when you see someone on a scooter and they are driving on the road and you want to pass you honk your horn and they move to the side and smile at you. its different then America. if you honk at someone in America they get angry. over here they thank you.
