The highest rated car insurance companies in California are the major companies. This includes Allstate and State Farm car insurance companies.
Currently the state of New Jersey has the highest auto insurance rates.
I have found that State Farm has the some of the highest quality insurance. State Farm is not always the cheapest however. It is normally quite expensive.
Detroit has the highest car insurance rates in the state of Michigan. On average, drivers pay 50% more for auto insurance in Detroit than in other Michigan cities.
Insurance in the state of NJ is some of the highest in the nation. I would suggest trying Geico for low rates.
The car insurance in Georgia is much cheaper than the insurance in Florida. Florida has some of the highest car insurance in the nation.
Car insurance is required in Massachussets.
The government requires you to get car insurance but they are not a car insurance provider. You could get insurance from Progressive, or State Farm, or Geico.
That state is about average between the highest and lowest states. Check the info here http://www.tiffanyinsurance.com/2007/10/average-car-insurance-rates-by-state.html
This may vary from state to state. In Mass, you have to have insurance in order to register a car (the insurance company has to stamp the registration form)
When you have no insurance on your vehicle, you void your registration - insurance is required by law. Yes, they can impound a car from out-of-state in that instance.
if you do not own a car you do not have to have insurance the insurance is tied to the registration when you register plates for a car and that is how the state keep track of you for insurance purposes I live in Ohio
