To reduce the insurance premium, the insured party may offer to pay a higher excess (deductible) than the compulsory excess demanded by the insurance company. The voluntary excess is the extra amount, over and above the compulsory excess, that is agreed to be paid in the event of a claim on the policy. As a bigger excess reduces the financial risk carried by the insurer, the insurer is able to offer a significantly lower premium.
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.
