You can get free quotes online at various insurance companies.  These quotes are easy to obtain.  You simply need to go online and fill out your personal information.  They will require such info as name, address, vehicle type, mileage to and from work etc.  In order to get an adequate and comparable quote be sure to include the same info and request the same deductible amounts.  After receiving the quotes call the insurance companies and ask if there is any way to get the insurance lower.  Check to see if they have plans that would require less money upfront.  Tell the company the quote that you received from another company.  They will do their best to beat the competition.  This will help you to find the best price available for your needs.

There are also online insurance comparison sites that will do all the comparisons for you.  They use the info that you put into their system such as name, address; vehicle type, mileage to and from work etc and they will compare all the major insurance carriers at one time.  This can save a lot of time.  You should still follow it up with a call to a representative at the companies that provide you with the best coverage and price.  Be aware of deductible costs and injury coverage.   These may reduce your premiums but can be costly if there is an accident or injury incurred.  Ask questions and make a wise choice based off of price, quality, and the experience and word of mouth of the insurance provider.  It may not be wise to choose a company that you have never heard of without finding sources that prove that it is a reliable provider.  Do not be afraid to ask the sales rep for stats on the services provided.  

Receiving free insurance quotes can be a great way to compare apples for apples and to save hundreds of dollars a year on insurance.  If you have had the same carrier for several years or if you have never done a comparison now might be a great time just to check on the cost of your carrier vs. the cost of another.  Free quotes are worth the time and effort.
