Auto insurance isn’t only great protection for your vehicle, it’s also the law. All states require some degree of insurance for your vehicle to protect you and other motorists. Coverage requirements will vary based on your financial responsibility for your car and your state’s requirements. Some states even require you to have liability insurance before you even get a license.
Some classes of vehicle ownership, or use, are "Crown Exempt" from the requirement to be covered under the Act including vehicles owned or operated by certain councils and local authorities, national park authorities, education authorities, police authorities, fire authorities, health service bodies, the security services and vehicles used to or from Shipping Salvage purposes. Although exempt from the requirement to insure, this provides no immunity against claims being made against them, so an otherwise Crown Exempt authority may choose to insure conventionally, preferring to incur the known expense of insurance premiums rather than accept the open-ended exposure of effectively, self-insuring under Crown Exemption.
There are many factors such as IDV, deductibles, seating capacity, cubic capacity, previous insurance history etc. that affect the insurance premium that you would pay. For comprehensive insurance plans, premium charges vary insurance provider per insurance provider on the basis of the coverage provided. Compare insurance premiums so that you get the best quote.
