In Boston's Dorchester section, drivers will see the average premium
fall to $1,670 from $2,033, a reduction of almost 18 percent.
The new rates apply to what insurance companies call experienced
drivers, who represent the most common category of insured driver.
The industry's calculations are based on a driver with six or more
years of experience, a vehicle that is a couple of years old, an average
driving record, and comprehensive and collision coverage with a
deductible of $500.
"We've said that if we could take fraud out of the system, rates
would come down," said Daniel Johnston, president of the Automobile
Insurers Bureau of Massachusetts. "Now we finally have proof."
The antifraud campaign has led to charges against or the arrest of
528 people, including lawyers and chiropractors, Johnston said.
Reduced fraud has also led to a reduction in claims filed with
insurers, which allows regulators to cut premiums.
In communities where fraud is less of a problem, and where the
average premiums are lower, the percentage reduction coming on April 1
is also less. For example, experienced drivers in Newton will see their
average premium drop 8.6 percent.
"This is exactly how the system should work, and we can lower
premiums even more in the future if we apply a similar approach to
reducing accidents," said Stephen D'Amato, a consultant to the Center
for Insurance Research in Cambridge.
Massachusetts is the only state where auto insurance rates are set by
state regulators.
Some insurers say rates would drop even further if regulation was
reduced and companies were allowed to compete for drivers' business.
