okay i got it done today..the place i did it is not at the Woqod station in abu hamour, infact its jus close to it. If you are coming from the Medical mission side, exit the road when you are opposite to the medical mission..and afew metres down you should see a porta cabin and a few cars in line..on the rite site..

Its open till 5.15..lunch break is from 12 to 12.30..

The police is only available in the mornings..so if you have failed in the legal requirement thing..you may have to come back in the mornings or you can just go to Madinat Khalifa Traffic Dept to waive it off

Best of luck
