I think this plan will save 2p but ending up costing thousands. Is HMG really so short of decent ideas?

We haven't needed a paper disc in the windscreen for a decade. The info on the Police cars computers is far more reliable than any printed disc in the window. Getting rid of a needless piece of paper will cost nothing.

As for the 'insurance disc' I don't see how that'd be any more reliable than the insurance certificate which can be obtained before cancelling said insurance. Technology has stopped that practice working as well.

In Zambia the cars had to display a disc certificate that the car had passed its MOT.

Do the DVLA not check for insurance and MOT before issuing a tax disc?

Yes - but only for the day the tax is issued.

""Can anyone see the mistake in the article ?"

You mean the extra 'not' in para 3?"

Yes, Avant. That is sloppy editing and completely changes the sense of the paragraph.
