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.
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.
It is an offence to use a motor vehicle, or allow others to use it without insurance that satisfies the requirements of the Act. This requirement applies while any part of a vehicle (even if a greater part of it is on private land) is on the public highway. No such legislation applies on private land. However, private land to which the public have a reasonable right of access (for example, a supermarket car park during opening hours) is considered to be included within the requirements of the Act.
In September 2012, it was announced that the Competition Commission had launched an investigation into the UK system for credit repairs and credit hire of an alternative vehicle leading to claims from third parties following an accident. Where their client is considered to be not at fault, Accident Management Companies will take over the running of their client's claim and arrange everything for them, usually on a 'No Win - No Fee' basis. It was shown that the insurers of the at-fault vehicle, were unable to intervene in order to have control over the costs that were applied to the claim by means of repairs, storage, vehicle hire, referral fees and personal injury. The subsequent cost of some items submitted for consideration has been a cause for concern over recent years as this has caused an increase in the premium costs, contrary to the general duty of all involved to mitigate the cost of claims. Also, the recent craze of "Cash for crash" has substantially raised the cost of policies. This is where two parties arrange a collision between their vehicles and one driver making excessive claims for damage and non-existent injuries to themselves and the passengers that they had arranged to be "in the vehicle" at the time of the collision. Another recent development has seen crashes being caused deliberately by a driver "slamming" on their brakes so that the driver behind hits them, this is usually carried out at roundabouts, when the following driver is looking to the right for oncoming traffic and does not notice that the vehicle in front has suddenly stopped for no reason. The 'staging' of a motor collision on the Public Highway for the purpose of attempting an insurance fraud is considered by the Courts to be organised crime and upon conviction is dealt with as such.
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.
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.
Providers can also offer sub-divisions of auto repair insurance. There is standard repair insurance which covers the wear and tear of vehicles, and naturally occurring breakdowns. Some companies will only offer mechanical breakdown insurance, which only covers repairs necessary when breakable parts need to be fixed or replaced. These parts include transmissions, oil pumps, pistons, timing gears, flywheels, valves, axles and joints. 
You’ll notice that none of that liability coverage pays for your car or injuries, nor for any injuries your passengers sustain if you cause a wreck. This is why many people — particularly those whose car isn’t yet paid off — want “full coverage” car insurance. This isn’t actually a type of coverage, but instead typically refers to policies that include liability coverage, plus comprehensive and collision coverages.
