http://www.state.ma.us/doi/Consumer/CSS_auto.html is the site where Massachusetts auto insurance consumers can read the actual wording of the policy. Sorry, this is only option in Massachusetts.

http://www.state.ma.us/doi/Consumer/WaysToSave_Contents.html is the site where you can read what the Massachusetts Consumer Affairs Dept. has to say about buying a Massachusetts auto insurance policy. I can do this faster than you can read it but if you want to hear what an independent party has to say then this is the resource for you.

http://www.state.ma.us/rmv/ is the Massachusetts Registry of Motor Vehicles website. They have lots of good info there (i.e. wait times at registry offices, registration renewals, address changes).
