Claims on multi car policies are usually dealt with similarly to single car policies. All multi car policies are different so it’s important to check with your insurer, but the best multi car insurance policies will not penalise one driver if another makes a claim. If someone else on the policy makes a claim, for example if your partner makes a claim on their car, your no claims bonus will not be affected.
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.
A compulsory car insurance scheme was first introduced in the United Kingdom with the Road Traffic Act 1930. This ensured that all vehicle owners and drivers had to be insured for their liability for injury or death to third parties whilst their vehicle was being used on a public road. Germany enacted similar legislation in 1939 called the "Act on the Implementation of Compulsory Insurance for Motor Vehicle Owners."
Police forces have the power to seize vehicles that do not have the necessary insurance in place, until the owner of the vehicle pays the fine and signs a new insurance policy. Driving without the necessary insurance for that vehicle is an offence that will be prosecuted by the police and will receive penalty. Same provision is applied when the vehicle is standing on a public road.
Any car insurance comparison tool you look at should have your state’s minimum car insurance requirements pre-loaded into its options. States requiring PIP or medpay are generally referred to as “no-fault” states, meaning that when injuries occur, each driver in a crash makes a claim with their own insurance company to pay for them. Beyond the PIP or medpay limit, the at-fault driver’s liability insurance kicks in to cover the rest.
