A campaign to remove uninsured cars from the roads is being rolled out across London.
The ANPR system checks number plates against vehicle databases
The Metropolitan Police traffic unit will train borough officers to detect and seize illegal vehicles to help reduce crime.
A police spokesperson said there is a link between uninsured vehicles and crime, including hit and run incidents.
Uninsured vehicles can be impounded and their drivers could get a £120 fine and six penalty points on their licence.
If they do not pay to retrieve their vehicle within seven days, it will be crushed or sold on.
London's traffic officers seized almost 13,000 uninsured vehicles between January and November 2007, often using Automatic Number Plate Recognition which checks number plates against vehicle databases.
The Metropolitan Police is now planning to extend the scheme so every borough officer will be able to use the tactic by the end of 2008.
During the launch in Brent this morning, 30 drivers had their vehicles seized and two were arrested for other offences.
Jenny Jones, road safety ambassador for the Mayor of London, said: "We are going to see more illegal drivers being caught this year.
"This has come from local communities who are saying we want these drivers off the road, so local police will now be able to do this as well."
Officers in Hammersmith and Fulham, Ealing, Lewisham, Hillingdon and Brent are already part of the scheme.
Ch Supt David Snelling, from the traffic unit, said: "Uninsured drivers are a danger to all road users.
"Each and every one of my traffic officers has seen first hand the long lasting and real pain caused by uninsured drivers who have been involved in fatal collisions."
