The reasons why Thailand got the highest, don't get me wrong the Thais are nice &friendly people but once they gets into their car they turned into a monsters. There many ways to improve the roads systems in Thailand if the law is much more stricts. Reasons why so many accidents & so many road died. 1) The Thais drives ther car way too fast. 2)If you leave enough spaces so incase you have to brake in an emergency, they don't care, if they see even alittle space they squzee in. 3) They drives or the ride bikes like they own the road, they simply do not have 'ROAD MANNERS' , they don't give signls or warning what they are goinng to do. They overtake on the insde. 4) Big lorries drives on the right lane! 5) The Thai believe in giving ways! 6) Motor bikes driving on the wrong sde of the road ! I always tell my husband from England, the road signs does not mean anything to the Thais, because they don't especially you can these kind of drivers outside Bangkok. Especially many in Nonthaburi areas & Sai Noi whrre we live ! My English husband said that if the Thai Governments put 'SPEED CAMERAS' on all the roads even those in the provinces, the Thai Governments will be very rich ! Traffic polices should be out on the roads & be very strict with the laws, those who break the laws give them a really 'HEAVY FINE', take away their drving licence band from driving for a year, those can't to pay fine lock them up untill they can get someone to bail them also off course take their driving licence away also ban from driving fora year ! I have been to many countries, Thailand seem to have so many rude, selfish & no manners motorists. I believed the Thai Governments can change the systems for better & Thailand will be a better place to live, drivers don't only think about themselves.
