My wife had a very good instructor in Chiang Mai. He told her the most important rules, and to watch around every time she maneuvered....He was really good. She had her driving license easy ! (That's no Guarantee I Know)
A couple of years later she did her driving lessons again in Europe and that was a lot of studying,...She studied a couple of months, did her exam and got it the first time. And I swear the exams were very hard and strict. They tried to trick her into making mistakes, but she did it excellently. She is now a excellent and safe driver. I let her drive as much as possible to get as much experience as possible, she drove in Germany, Switzerland, France The Nederlands and Belgium,...without a problem.
