Thai Driving License renewal

[Scout]

My driving licence, the one that I obtained 5 years ago after starting this thread, expires at the end of this month. I renewed it at Pranburi last week.

I believe if you renew a license the day after it expires, you receive an extra year of validity for the new license. I know I get 6 years (instead of only 5) by following this strategy. It probably also works when renewing while on a tourist visa, I suspect you would get 3 years instead of only 2.
