More than one million drivers across the UK do not have insurance, according to new research.
East London is the worst place in the country with one in eight cars uninsured followed by Liverpool, Bradford and Manchester.
Since 2011, the Metropolitan police have seized 119,000 cars in the capital – approximately one third of the total across the UK.
The findings are based on analysis of data from the Motor Insurers’ Bureau (MIB) by insurance company Churchill.
Ashton West, chief executive of the MIB, said: “Only four years ago, east London was the home of the Olympics, a focus of immense pride. It’s been given a less welcome title: that of the home of uninsured driving.
“But actually it’s a nationwide issue and affects many other key UK cities including Manchester, Birmingham, Bradford and Leeds.
“MIB is committed to raising awareness about the problem and driving down levels of uninsured driving.”
Churchill’s Mark Chiappino told the Guardian : “The number of uninsured vehicles on the roads is alarming. Car insurance is a legal requirement but hundreds of thousands of motorists continue to flout the law.
“Drivers across the UK are paying higher premiums as a result of unscrupulous drivers that fail to insure their vehicles.“
If motorists are hit by an uninsured driver, there is no insurance company to foot the bill for damage to their car or personal injury. However, claims can still be made via the MIB which is funded by insured driver’s premiums.
Anyone hit by an uninsured driver should try to make a note of the vehicle make, model and registration number, the name, address and contact details of the driver and any independent witnesses.
Mr Chiappino added: “We care calling for a greater recognition of the risks of uninsured motoring in the UK and far tougher penalties for those convicted of this offence.”
