The number of drivers failing to pay road tax has fallen in the past year, according to Government figures.
This year, the rate of untaxed vehicles on the roads is thought to be around 0.5%, compared to a figure of 0.7% last year.
The drop could mean vehicle tax evasion will cost £30 million less in lost revenue this year, at around £49 million for 2008-09 compared with £79 million in the previous year.
However, the amount of motorcyclists evading vehicle excise duty (VED) has increased in the past year, from 2.3% in 2008 to 3.2%.
Across the country, the East Midlands was the region with the least amount of tax evasion, with only 0.4% of drivers not paying, while Scotland had the highest amount with 0.7%.
Driver and Vehicle Licensing Agency (DVLA) chief executive Noel Shanahan said: "We've made it easier than ever to license a vehicle and our online road tax renewal system continues to be a great success.
"We are also cracking down on people who flout the law, so I am delighted that we have seen another fall in the level of road tax evasion.
"We know that the overwhelming majority of motorists comply with the law and properly license their vehicles, but we're committed to continue to take serious action against the very small minority who don't."
