ATLANTA - In a one-year period, the cost of medical care and productivity losses associated with injuries from motor vehicle crashes exceeded $99 billion – with the cost of direct medical care accounting for $17 billion, according to a study by the Centers for Disease Control and Prevention.

The total annual cost amounts to nearly $500 for each licensed driver in the United States, said the study in the journal Traffic Injury Prevention.

The one-year costs of fatal and non-fatal crash-related injuries totaled $70 billion (71 percent of total costs) for people riding in motor vehicles, such as cars and light trucks, $12 billion for motorcyclists, $10 billion for pedestrians, and $5 billion for bicyclists, the study said.

"Every 10 seconds, someone in the United States is treated in an emergency department for crash-related injuries, and nearly 40,000 people die from these injuries each year. This study highlights the magnitude of the problem of crash-related injuries from a cost perspective, and the numbers are staggering," said Dr. Grant Baldwin, director of CDC's Division of Unintentional Injury Prevention, National Center for Injury Prevention and Control.

The study also found:

• More men were killed (70 percent) and injured (52 percent) in motor vehicle crashes than women. Injuries and deaths among men represented 74 percent ($74 billion) of all costs.

• Teens and young adults made up 28 percent of all fatal and nonfatal motor vehicle injuries and 31 percent of the costs ($31 billion). These young people represented only 14 percent of the U.S. population.

• Motorcyclists made up 6 percent of all fatalities and injuries but 12 percent of the costs, likely due to the severity of their injuries.
