the ONLY way to get "cheap" rates is to have the minimum coverage required by law in your state.... meaning liability only with the minimum level (probably 15/30 and 5). as far as if this is recommended..... thats your decision. if you hit someone and the damage on their vehicle/property is more than 5g, then youre screwed if they come after you and sue. they get injured, and you have nothing near enough coverage and you live with your parents, say goodbye to your parents' house.
