Inderjeet Kaur, 29, is jailed after taking around 150 theory and practical tests for other drivers in the UK.
Kaur worked between 2018 and 2020 across Swansea, Carmarthen, Birmingham, and London.
The mother of one was caught after staff at centers started to get suspicious if she was impersonating others.
They alerted the Driver and Vehicle Standards Agency (DVSA), and an investigation was started by Tarian, the regional organized crime team for southern Wales.
Officers learned that Kaur took tests predominately for those who could not speak English in exchange for money.
Inderjeet from South Wales pleaded guilty o fraud at Swansea Crown Court and was jailed for eight months.
Detective Chief Inspector Steven Maloney of Tarian gave a brief statement:
"The crimes Kaur committed put innocent road users at risk by allowing unskilled and dangerous motorists to have seemingly legitimate licenses."
"Safety on our roads has always been a priority, and arresting those that flaunt the law ensures that we can keep unqualified drivers off the road."
He concluded that "by working with the DVSA, this complex criminal investigation highlighted the extent of Kaur's offending, which was purely out of greed."
Head of regulatory services and transformation at the DVSA, Caroline Hicks, also talked to the media, saying:
The DVSA's priority is to protect everyone from unsafe drivers and vehicles.
"Driving and theory tests exist to help ensure people have the correct knowledge, skills, and attitude to drive on our roads."
"Circumventing the tests puts lives in danger, we have methods in place to detect test fraud and will come down hard on the people involved."
"This includes canceling test passes that have been gained fraudulently."
