An automobile insurance company makes money by, in part, taking in premiums, and, over time, having lower operating costs [e,g, monies paid out in claims] than those premiums. Just how much are those premiums? Maryland car accident lawyers know that Maryland is an expensive place to insure a car, costing about $929 year for full coverage. Maryland car accident lawyers handling Baltimore car collision cases may know that it costs a hell of a lot more to insure that same car in Baltimore City- $2842 a year, on average.
