So you are the one who was driving on side road to over take complete lane from EZDAN 4 TO EZDAN 3. I have personally seen the policeman to write manually car numbers who were driving offroad to over take that lane in morning arround 6.15. ( check your time ) :)

I was irritated when i have seen same person trying to overtake almost 3 days. why he cant start only 5 minute early to save huge loss....(1000 bucks it much to me )

well hope you got the reason now. and that fine is real unusual,unexpected driving in Doha.
