I have posted this on another person who's insurance had just run out,eventhough the certificate had run out some insurance providers would still considder you to be on cover for 14 days after the expirery date as long as you intended to renew with them.Just because the expirery of the cartificate date had past the insurance company may still be covering you if this is the case you were not driving without insurance.Ask the insurance company if they have this policy to give 14 days grace to renew.if they have you were covered by insurance and cant be done for driving without insurance.
