Motorists who keep an uninsured vehicle - even if it is off the road - face a fine or could even have their car destroyed under new laws coming into force from June 20.
Under the new Continuous Insurance Enforcement law it will be an offence to keep an uninsured vehicle. Warning letters will be sent to the offenders.
Failure to act on the warning - either by taking out insurance or declaring their vehicle off the road - will lead to a fine of £100. Offenders could also face a court prosecution, or have their car clamped, seized and destroyed.
Road safety minister Mike Penning said: "Anyone who receives a warning letter should take action immediately by getting insurance or contacting the DVLA (Driver and Vehicle Licensing Agency) to declare their vehicle off the road."
Ashton West, chief executive of the Motor Insurers' Bureau, said: "We know who the registered keepers are with vehicles that have no insurance and letters will be dropping on to their doormats from this week. It's no longer a case of if you will get caught, but when you will get caught.
"An estimated 1.4 million drivers are flouting the law by driving without insurance. This is a serious offence and results in accidents that cause about 160 deaths each year and more than 23,000 people are injured by uninsured drivers. It also adds around £30 per year to honest drivers' motor insurance policies."
