Liability insurance pays for damage to someone else’s property or for injury to other persons resulting from an accident for which the insured is judged legally liable; collision insurance pays for damage to the insured car if it collides with another vehicle or object; comprehensive insurance pays for damage to the insured car resulting from fire or theft or many other causes; medical-payment insurance covers medical treatment for the policyholder and his passengers.
Motor insurers in the UK place a limit on the amount that they are liable for in the event of a claim by third parties against a legitimate policy. This can be explained in part by the Great Heck Rail Crash that cost the insurers over £22,000,000 in compensation for the fatalities and damage to property caused by the actions of the insured driver of a motor vehicle that caused the disaster. No limit applies to claims from third parties for death or personal injury, however UK car insurance is now commonly limited to £20,000,000 for any claim or series of claims for loss of or damage to third party property caused by or arising out of one incident.
Insurance companies have started using credit ratings of their policyholders to determine risk. Drivers with good credit scores get lower insurance premiums, as it is believed that they are more financially stable, more responsible and have the financial means to better maintain their vehicles. Those with lower credit scores can have their premiums raised or insurance canceled outright. It has been shown that good drivers with spotty credit records could be charged higher premiums than bad drivers with good credit records.
