You’ll notice that none of that liability coverage pays for your car or injuries, nor for any injuries your passengers sustain if you cause a wreck. This is why many people — particularly those whose car isn’t yet paid off — want “full coverage” car insurance. This isn’t actually a type of coverage, but instead typically refers to policies that include liability coverage, plus comprehensive and collision coverages.
The registration number of the vehicle shown on the insurance policy, along with other relevant information including the effective dates of cover are transmitted electronically to the UK's Motor Insurance Database (MID) which exists to help reduce incidents of uninsured driving in the territory. The Police are able to spot-check vehicles that pass within range of automated number plate recognition (ANPR) cameras, that can search the MID instantly. It should be noted, however, that proof of insurance lies entirely with the issue of a Certificate of Motor Insurance, or cover note, by an Authorised Insurer which, to be valid, must have been previously 'delivered' to the insured person in accordance with the Act, and be printed in black ink on white paper.
Auto insurance is financial protection, and not just for the investment you made when you bought your car. After a really serious accident, bills for damage and injuries can easily reach into hundreds of thousands of dollars. If you happen to cause such a wreck, the victims could sue you. In the worst case scenario, assets such as your savings and home could be seized.
