Insurancewide.com is urging ladies to carry their woman car insurance documentation in their vehicles so that they can prove they are covered if stopped by police.
The motor insurance quote comparison company is advising women to keep their certificate with them in the light of a recent case where a lady had her car confiscated because the Motor Insurance Database had not been updated correctly.
A spokesperson for Insurancewide.com said: "This is a case of guilty until proven innocent. If an insurer is late in reporting a new policy owner's details to the Motor Insurance Database then the unsuspecting driver could mistakenly be deemed 'uninsured' and then fined if stopped by police.
"Every driver can avoid this hassle and embarrassment by simply keeping photocopied proof of insurance in the glove compartment as soon as they receive the certificate from the insurer."
He added that in the future, more woman car insurance companies will supply electronic versions of the certificate which will allow motorists to print them off straight away.
"This will reduce the risk of being wrongly perceived as uninsured in the first couple of days while the certificate is still in the post," he said.
At present, UK car insurance companies have 14 days in which to update the Motor Insurance Database, although this timescale is being cut to seven days from January 2008.
