Traffic crashes are costing the U.S. economy close to a trillion dollars a year, according to a new study.  The National Highway Traffic Safety Administration study found that wrecks in the year 2010 led to more than 870-billion dollars in economic loss and harm to society.

Those costs include property damage, medical expenses, legal costs, increased traffic congestion and the need for more expensive medical services.

The report released over the weekend found that the cost of traffic crashes was equal to almost two-percent of the nation's gross domestic product in 2010.
