Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate has she made of the number of vehicles with a SORN certificate that are still being driven on the public highway.

The Department for Transport last carried out a roadside survey in 2023 which estimated the rate of vehicle excise duty evasion among vehicles seen on UK roads. The survey results were published on 7 December 2023 and can be found at https://www.gov.uk/government/statistics/vehicle-excise-duty-evasion-statistics-2023/vehicle-excise-duty-evasion-statistics-2023. Out of the unlicensed vehicles observed during the latest survey, five per cent were shown on the Driver and Vehicle Licensing Agency’s database as having a current Statutory Off Road Notification in place.
