Motor Vehicle Liability Insurance
requirements in Tennessee are well above the
average for claims. The Insurance Information
Institute reports the average claims for auto
liability losses, as compiled by the Insurance
Services Office (ISO Properties, Inc.).

For 2005,
private passenger auto liability losses averaged
$11,271 for bodily injury claims and $2,690 in
property damage claims. The bodily injury claims
average increased 17 percent from 1996 to 2005
(despite a 42 percent increase in the Consumer
Price Index for medical care
10
). The property
damage claims average increased 27 percent.
However, the average may not necessarily reflect
the range of claims.
In a 2003 study by the Insurance Research
Council on a sample of bodily injury claims, only
one percent of claims were over $50,000 and
three percent were over $25,000. However, these
claims represent 26 percent of total insurance
payments.
11
Information provided by one of the
larger insurance companies in Tennessee for 2005
indicated that the vast majority of claims were
within the state’s minimum insurance limits.
Eighty-six percent of bodily injury claims were less
than $25,000; 95 percent were less than $50,000.
Ninety-six percent of property damage claims
were less than $10,000.
State and insurance officials interviewed
indicated that the $10,000 property damage
liability insurance may no longer be sufficient
to cover many accidents because most cars
are worth more than $10,000. In 2006, the
average price of a new car was about $27,800 and
the average sales price of a used car was
estimated at $13,900.
12
However, motor vehicles
lose value over time and insurance pays only the
vehicle’s current value if the car cannot
economically be repaired. The average property
damage claim in 2005 of $2,690 was significantly
lower than the $10,000 minimum limit.
Cost of insurance at different levels of
coverage
Increasing the property damage limit from
$10,000 to $25,000 would require a six percent
increase in the base rate for auto liability
insurance. An increase in bodily injury limits
from 25/50 to 50/100 would increase the base
rate by 18 percent. Insurance companies start
with a “base rate” for different kinds and dollar
amounts of auto insurance and then apply
different factors to calculate a rate. The
Department of Commerce and Insurance provided
a comparison of base rates for personal vehicles
in Tennessee compiled by the Insurance Services
Office (ISO Properties, Inc.) for 2003. The base
rates show the increase resulting from changes in
liability coverage. Actual premium costs vary
significantly based on several factors including
location, gender, age, miles driven, driving record,
and coverage requested.
Increasing minimum limits from 25/50/10 to 50/
100/25 would increase insurance premiums an
estimated 12 to 22 percent and between $15
and $193 per six-months depending on several
factors. To determine the potential dollar impact
on premiums from increased liability limits, several
Tennessee insurers provided rate quotes at the
current limits of 25/50/10 as well as at limits of 50/
100/25 for several examples of drivers. Exhibit 4
shows average rates for different types of drivers.
The data was provided by several Tennessee
insurers that collectively wrote about 42 percent of
the state’s 2005 personal auto insurance
premiums. As shown in Exhibit 5, rates as well as
the increase in rates would be greater for higher
risk drivers including those insured by
nonstandard insurers, those with a poor driving
record, or other higher risk factors such as age.
Insurance company representatives interviewed
also warned of “claims inflation” if the minimum
requirements are increased. In many cases,
parties settle for the current policy limits even
when the actual damages exceed the limits. With
higher limits, average claim costs may increase,
resulting in potentially higher rates. One insurance
company noted that raising the limits in Georgia
made it more economically feasible for injured
parties to collect damages through hiring attorneys
to file lawsuits. Ultimately, claim amounts and
premiums increased.
Other potential issues to consider
Does Tennessee need to increase monitoring
and enforcement of Financial Responsibility
Laws?
The type of monitoring and the type and level of
enforcement of financial responsibility laws were
not within the scope of this study. However, the
high rate of uninsured motorists in Tennessee
indicates that additional action may be needed to
require motorists in Tennessee to be financially
responsible. Information below compares
Tennessee to other states in these areas.
Monitoring
Tennessee primarily uses a passive/reactive
approach to financial responsibility. The state
