A new study by the Insurance Research Council (IRC) finds that claimed losses for auto injuries have escalated at vastly different rates across four states with no-fault auto insurance regulations. From 1997 to 2002, the average amounts that personal injury protection claimants reported for expenses stemming from their injuries increased 122 percent in Colorado, 60 percent in New York, 37 percent in Florida, and just 2 percent in Michigan. The study finds escalating medical costs are the key factor behind the growth in losses in Colorado, New York, and Florida. Skyrocketing claim costs contributed to the 2003 Colorado decision to end the state’s no-fault auto insurance system.
