The safety agency produces such calculations about once a decade.
The economic cost was the equivalent of nearly 2 percent of the U.S. gross domestic product in 2010. Factors contributing to the toll include productivity losses, property damage, and cost of medical and rehabilitation treatment, congestion, legal and court fees, emergency services and insurance administration and costs to employers. Overall, nearly three-quarters of these costs are paid through taxes, insurance premiums and congestion-related costs such as travel delay, excess fuel consumption and increased environmental impacts.
"While the economic and societal costs of crashes are staggering, today's report clearly demonstrates that investments in safety are worth every penny used to reduce frequency and severity of these tragic events," Transportation Secretary Anthony Foxx said in a statement.
The size of the impact detailed in the study may help Foxx make his case as he presses Congress to increase the amount the government can fine automakers for safety violations. Penalties currently are capped at $35 million. Foxx is urging that the lid be increased to $300 million, and some senators have endorsed eliminating the limit entirely.
The most prominent recent example of such violations is General Motors' delayed reporting of ignition-switch failures. GM says 13 people have died in crashes linked to the problem, but the head of the safety agency, David Friedman, says it is likely the final death toll will be higher.
The study cites several behavioral factors that contributed to the enormous price tag created by motor vehicle crashes:
—Alcohol-related driving accounted for $199 billion, or 23 percent.
—Crashes involving a speeding vehicle accounted for $210 billion, or 24 percent.
—Distracted driving accounted for $129 billion, or 15 percent.
—Preventable fatalities and injuries attributable to occupants who weren't wearing their seatbelts accounted for $72 billion, or 8 percent.
In 2010 alone, over 3,350 people were killed and 54,300 were seriously injured unnecessarily because they failed to wear their seat belts.
"Seat belt non-use represents an enormous lost opportunity for injury prevention," the report said.
