WASHINGTON (AP) — Traffic fatalities rose 5 percent last year, according to an analysis of preliminary state data, reversing a seven-year decline in which the number of annual traffic deaths reached their lowest level in more than six decades.

An estimated 36,200 people died motor vehicle accidents in 2012, the National Safety Council said Tuesday. That's up from 34,600 deaths the previous year. It's the first increase since 2004 to 2005.

Crash injuries requiring medical care also rose 5 percent last year to 3.9 million, the council said. The estimates are based on monthly fatality data the council receives from every state and the District of Columbia.
