i went to madina khalifa traffic dept and said that i was not in qatar or uae at that time. my car was in qatar as i away on vacation.
they advised me to get a letter from customs dept on corniche as to when my car had exited/entered qatar borders.
customs dept charged me 10 rial and issued me a letter indicating the dates when i had exited/re-entered qatar.
i submitted this at madina khalifa traffic dept.
my traffic fine of 700 uae dirhams was cancelled...
