I will advise to keep the cash ready and go.
earlier, i Had 500 QR fine for overspeed, and had to go to Dubai. I was tense that I may be caught, but nothing happened.

but traffice offence ( jumping signals ) are different, I heard , it is linked to you personally, rahter than overspped which is lnked to the vehicle number.

I am not sure, but dont pay now,, keep cash ready at airport :-)
