Drunken driving, speeding, distracted driving and not wearing a seatbelt are the major causes of injuries and deaths in motor-vehicle crashes in the United States, according to the National Highway Traffic Safety Administration.

According to the U.S. Census Bureau, there were 35,900 traffic deaths nationwide in 2009; according to the Insurance Institute for Highway Safety, there were 32,719 traffic deaths in 2013.

“Given that fact that the majority of collisions are caused by human behaviors that are preventable, there is hope that these fatality rates can continue to be reduced,” the Accident Data Center reports.
