Up to 85 per cent of the state's worst drivers do not hold a valid driver's licence, police will reveal today.
Police will also announce a five-week campaign to target the top 500 worst drivers including repeat hoons, drink-drivers and drivers who flee police.
Operation Road BIA will use road policing specialists, detectives and local police en masse to target high-risk areas, including Dandenong, Yarra, Casey, Darebin, Whittlesea, Hume and Geelong.
Assistant Commissioner for road policing Robert Hill said the behaviour of the top 500 worst drivers was criminal and the dangers to innocent road users was unacceptable. He said police research showed that unauthorised drivers were over-represented in road trauma and created extra risks on the road.
"We believe less than 15 per cent of drivers identified in the top 500 hold a current licence," Mr Hill said. "The rest are either unlicensed, disqualified, suspended, have surrendered their licence or had it cancelled. Most disturbingly, there are also a few who have never even had a licence. What are these people doing on our roads?"
Police will use covert and marked patrol cars, booze and drug buses and automatic number plate recognition technology in an effort to detect and take repeat-offender drivers off the road.
Mr Hill said the police had enlisted the help of other agencies, including VicRoads, Victorian Taxi Directorate, WorkSafe Victoria, Department of Immigration, Customs and Border Protection and the Sheriff's Office.
"We will work with our partners over the next five weeks to send a strong message to motorists, and that is - if you know you're not supposed to be behind the wheel, don't do it. It's that simple," he said.
Mr Hill said there had been 14 more deaths on the state's roads in August compared with the same month last year. "We all need to play our part and stop the carnage," he said.
