– that is, the revenue would be exclusively dedicated to a particular expenditure, namely the newly established Road Fund. Excise duties specifically for mechanically propelled vehicles were first imposed in 1921, along with the requirement to display a vehicle licence (tax disc) on the vehicle. End of hypothecation The accumulated Road Fund was never fully spent on roads (most of it was spent on resurfacing, not the building of new roads), and became notorious for being used for other government purposes, a practice introduced by Winston Churchill when he was Chancellor of the Exchequer. In 1926, by which time the direct use of taxes collected from motorists to fund the road network was already opposed by many in government, the Chancellor, Winston Churchill is reported to have said in a memo: "Entertainments may be taxed; public houses may be taxed ... and the yield devoted to the general revenue. But motorists are to be privileged for all time to have the tax on motors devoted to roads? This is an outrage upon ... common sense." Hypothecation came to an end in 1937 under the 1936 Finance Act, and the proceeds of the vehicle road taxes were paid directly into the Exchequer. The Road Fund itself, then funded by government grants, was not abolished until 1955. 1990s Since 1998, keepers of registered vehicles which had been licensed since 1998, but which were not currently using the public roads, have been required to submit an annual Statutory Off-Road Notification (SORN). Failure to submit a SORN is punishable in the same manner as failure to pay duty when using the vehicle on public roads. It was announced in the 2013 Budget that SORN declarations would become perpetual, thus removing the need for annual renewal after the initial declaration has been made. In June 1999, a reduced VED band was introduced for cars with an engine capacity up to 1100cc. The cost of 12 months tax for cars up to 1100cc was £100, and for those above 1100cc was £155. Emissions ratings tax During the 1990s, political arguments were put forward for the abolition of VED. Among the proposals was a suggestion that VED could be replaced by increased fuel duty as an incentive for consumers to purchase vehicles with lower emission ratings. The proposal was politically unappealing, as it would increase costs for businesses and for people living in rural areas. Rather than
