Motorists are being urged to remember that all vehicles have to be insured by spring this year when a new law comes into play, unless their vehicles are being kept off the road and the DVLA knows about it.
Information about the legislation will be issued with all new V11 tax renewal forms but will also be available on the direct.gov website.
The DVLA's David Evans said: "We know that uninsured drivers are a menace on our roads and add around £30 to honest motorists' premiums.
"It is vitally important that motorists understand the change and how it will impact on them. That is why we have added new information today to direct.gov which offers clear advice to help motorists understand the new rules."
Neil Drane, a manager at the Motor Insurers' Bureau, said: "The change in law is a stepping-up of enforcement activity, so that not only those vehicles driven without insurance will be caught, the registered keeper must make sure that their vehicle is insured all the time.
"And if it is, then they need not be concerned.
"The DVLA and MID will be systematically checked, so that the levels of uninsured driving are reduced even further."
The British Insurance Brokers Association's Graeme Trudgill said: "Continuous insurance enforcement will help reduce the £500 million burden on innocent motorists caused by uninsured drivers.
"Vehicle keepers should ensure they stay insured or SORN their vehicle if it is laid up. Vehicle keepers can always check at www.askmid.com or speak to their insurance broker or company if they have any doubt."
