Road Traffic Act Only Insurance differs from Third Party Only Insurance (detailed below) and is not often sold, unless to underpin, for example, a corporate body wishing to self-insure above the requirements of the Act. It provides the very minimum cover to satisfy the requirements of the Act. Road Traffic Act Only Insurance has a limit of £1,000,000 for damage to third party property, while third party only insurance typically has a greater limit for third party property damage.
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.
Several jurisdictions have experimented with a "pay-as-you-drive" insurance plan which utilizes either a tracking device in the vehicle or vehicle diagnostics. This would address issues of uninsured motorists by providing additional options and also charge based on the miles (kilometers) driven, which could theoretically increase the efficiency of the insurance, through streamlined collection.
