Motor vehicle litigation added $43.84 billion to U.S. auto liability insurance costs from 2015 through 2024. During 2024, there were 6,809 federal motor vehicle tort filings recorded.
Why it matters
The rise in litigation activity, coupled with increased claim severity and award amounts, has outpaced the frequency of underlying insurance claims. This shift has placed significant upward pressure on the overall costs of auto liability coverage.
Federal motor vehicle tort filings grew at a 5% compound annual rate from 2014 through 2024. Over this same period, 52.4% of all motor vehicle tort cases concluded in a settlement.
The details
Researchers determined that 50.6% of the U.S. population resides in the 11 states where complete tort filing and disposition data is available, allowing for state-level projections. These figures reflect an estimated $1.07 billion in excess litigation value in federal cases and $42.77 billion in state courts.
Timeline
From 1995 to 2004, the average plaintiff judgment award was $377,000.
Between 1995 and 2008, tort filings declined at an annualized rate of 2.8%.
Between 2014 and 2024, tort filings rose at a 5% compound annual rate.
From 2015 through 2024, litigation added $43.84 billion to insurance costs.
In 2024, federal motor vehicle tort filings reached 6,809.
Roadmap
The automotive insurance industry is currently contending with a reversal of long-term filing trends that previously saw a decline in litigation activity. This escalation marks a departure from the period between 1995 and 2008, when tort filings consistently trended downward.
The rise in excess litigation values directly contributes to higher auto liability insurance premiums for the average driver. These systemic cost increases are passed down as insurers adjust rates to account for the growing frequency and severity of legal awards.
The takeaway
Drivers should be aware that insurance costs are influenced by broader legal trends and the frequency of tort filings across the nation. Understanding these shifts can help policyholders navigate the changing landscape of auto liability coverage and premium adjustments.
