Boston Globe:
A 27-year-old single woman with a perfect driving record could see her insurance premium increase an average of 5.2 percent this year, while an older married couple who each had major at-fault accidents every three years could have their premiums decrease by nearly 14 percent under the state's new competitive auto insurance system, which takes effect April 1, according to two consumer groups that analyzed rates.
The potential unintended consequence of the new system is the result of a rate-setting process in which a motorist's driving record is not given as much weight as credit rating, marital status, or other factors unrelated to driving, according to a study to be released today by the Massachusetts Public Interest Research Group and the Center for Insurance Research.
