This closed claim study updates IRC’s ongoing research on injuries in auto accidents based on a sample of more than 70,000 auto injury claims paid by major auto insurers countrywide. The report explores auto injury claim patterns under each of the five principal private passenger auto insurance coverages, comparing 2002 data to results from similar studies conducted in 1997, 1992, 1987, and 1977. The study examines trends in injury claim patterns including characteristics of the accidents and those injured, medical treatment, losses and payments, the claim settlement process, and the impact of attorney involvement.
