Driving without the necessary insurance for that vehicle is an offence that can be prosecuted by the police and fines range from 841 to 3,287 euros. Police forces also have the power to seize a vehicle that does not have the necessary insurance in place, until the owner of the vehicle pays a fine and signs a new insurance policy. The same provision is applied when the vehicle is standing on a public road.
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.
Two of the most important factors that go into determining the underwriting risk on motorized vehicles are: performance capability and retail cost. The most commonly available providers of auto insurance have underwriting restrictions against vehicles that are either designed to be capable of higher speeds and performance levels, or vehicles that retail above a certain dollar amount. Vehicles that are commonly considered luxury automobiles usually carry more expensive physical damage premiums because they are more expensive to replace. Vehicles that can be classified as high performance autos will carry higher premiums generally because there is greater opportunity for risky driving behavior. Motorcycle insurance may carry lower property-damage premiums because the risk of damage to other vehicles is minimal, yet have higher liability or personal-injury premiums, because motorcycle riders face different physical risks while on the road. Risk classification on automobiles also takes into account the statistical analysis of reported theft, accidents, and mechanical malfunction on every given year, make, and model of auto.
According to the Insurance Information Institute, in the United States in the early 21st century, about two-thirds of the money spent on premiums for private passenger auto insurance went to claims. More than half of this amount covered car damage. The rest covered personal injuries. The remaining third of the money spent on premiums covered insurance companies’ expenses—such as commissions, dividends to policyholders, and company operations—and contributed to their profits.
