How much do you pay for car insurance?

I am going to Alaska and I require assistance about wellness insurance.?

Is there a list of ratings of leading auto insurance organizations? What is a good auto insurance company?

"Can i add my insurance policy and my brother and his vehicle? He doesn't have insurance cuz he cannot pay the total big down payment to start out their own policy. Can i only add him and his auto to quarry? I actually don't travel his car and he does not get quarry
