Almost one in four disqualified motorists are consistently escaping being put off the roads despite being the subject of a court-imposed driving ban.
Figures published by the Department of Transport show the authorities have been unable to enforce the disqualification of over 12,200 motorists since 2017 because their identities cannot be matched with records of the National Vehicle and Driver File operated by the department.
The figures show the annual proportion of cases where court disqualifications cannot be given effect has consistently ranged between 22% and 25% over the past six years.
