Hi safisk619. check on this http://www.moi.gov.qa/TFCViolations/English/EnglishInput.jsp. Just enter the details to see if anything has been logged under your vehicle. (usually it takes about 24 hours to update online)

Recently something like this happened to couple of my friends, and the moment they realized that they did a mistake, they went to the nearest traffic office and explained the situation and the officers have asked them to pay a lesser fine. and the amount was waaaayyyy less than the actual fine.

But im not sure if you could do this since now it has taken sometime.
