A man who wore wigs and fake moustaches to impersonate drivers and help them illegally obtain licences has been jailed.
Gageen Preet Singh, 35, donned the disguises to help candidates across the country pass their practical and theory tests.
The Indian national charged people £3,000 for a practical driving test and £600 to sit a theory exam, investigators said.
Around £52,000 in cash was seized when Mr Singh was arrested, thought to be just a small proportion of his earnings from the crimes, officers said.
He is understood to have operated principally in Indian communities throughout the South East, London, the Midlands, the North East and East Anglia.
This marked the second time Singh had been brought to justice for driving test fraud, police said.
He was sentenced to eight months jail after being caught red-handed taking a test in Milton Keynes, Buckinghamshire, in October last year.
But following his release in February this year, he re-started his illegal operation but failed to evade investigators for long.
Four months later he was arrested again and he pleaded guilty at Reigate Magistrates' Court in Surrey to 15 offences of fraud by impersonating test candidates and of driving while disqualified.
Before he was sentenced at Guildford Crown Court on Friday, he also asked for 156 further offences to be taken into consideration, Sussex Police said.
When Mr Singh is eventually able to drive again he may be facing a hefty rise in hiscar insurance costs.
Singh, of no fixed address, received a 12-month prison sentence for the fraud offences and a two-month jail term to run consecutively for the driving while disqualified offences.
