An area of great misunderstanding in motor insurance is the scope of the cover to drive. Two specific problems arise. When other named drivers appear on the certificate of insurance, this does not give them cover to drive other vehicles, unless that other vehicle is insured for that driver. The misunderstanding arises because the certificate does give the policyholder, but not the other driver, the cover to drive another vehicle. But that leads to the second problem. The extension to drive another vehicle does not usually give comprehensive cover to the second vehicle, but only the basic requirements of the Road Traffic Act 1988, namely, cover against third party liability. The Ombudsman makes no criticism against insurers for this, it is merely apart of motor insurance law. He does suggest, however, that it might be worthwhile for certificates to reflect this all important point in clearly expressed language.
