Many drivers who cause accidents expect to see an increase in their auto insurance premiums.
But even those who are deemed not culpable could end up paying more for coverage, a report from a consumer group finds.
The Consumer Federation of America sought online price quotes from five of the largest auto insurers in 10 cities to see what happens to premiums after drivers are in accidents.
The study found that based on the quotes, drivers in New York City and Baltimore tend to pay the most after being involved in accidents that they did not cause.
The penalties add to the costs of auto insurance, which is required for drivers in most states, said Doug Heller, the researcher who conducted the analysis for the consumer federation.
"Innocent drivers who don't cause accidents should not be charged more because someone else hit them," J. Robert Hunter, the consumer group's director of insurance, said in a telephone conference call this week with reporters.
It is the latest in a series of reports that the federation has published on car insurance costs.
The new study said that the average annual premium increase quoted drivers with a not-at-fault accident on their records ranged from $60 in Atlanta to more than $400 in Queens, New York.
