Question to the Department for Transport:

To ask the Secretary of State for Transport, what percentage of ANPR misreads occurred in each of the last five years of the DfT's roadside surveys.

The Department does not readily hold figures on the percentage of ANPR misreads from vehicle excise duty evasion statistics roadside survey. Misreads are managed through quality assurance and correction processes, with any remaining uncertainty reflected in the confidence intervals published alongside Vehicle Excise Duty evasion estimates.
