@jaan99, drivers' licenses have a picture printed on it and also have NIC number.
When police guys do not have to accept anything they won't, a bus had ran the light to hit me when I had the FIR (roznamche main indaraj) for my lost license and CNIC and he said there is no such entry in the register and I never had a license, but when an army officer called in they found out from computerized license office that I have a license. The sad thing is you need sources in such a scenario. Maybe Police guys do not die or made alive again, or they think so atleast.
MORALE OF THE STORY: do not depend on FIR or report, get your license and do not drive till then. Its just a couple of hours for renewal.
