I have around 10 vehicles I need to make sure are all legal and road worthy and the visual windscreen tax disk expiry date was a simple but efficient way of ensuring this but the more crucial fight against un-taxed vehicles I believe is much harder to monitor now that the visual disks are gone.
With police budgets stretched over the past two years the number of police vehicles with built in license plate recognition cameras can't be as much as predicted so I'm not surprised revenue is down and I would bet that any new survey figures would show the number of un-taxed vehicles would now be greater than before the tax disk was culled.
