2013 was the safest year for Missouri roads in more than six decades.
Patrol Capt. Tim Hull says that's the lowest number since 683 people died on Missouri roads in 1947.
Missouri officials have placed an emphasis on reducing traffic fatalities in recent years.
The Department of Transportation has installed cables in the medians of some four-lane highways to prevent cross-over crashes and rumble strips on the sides to warn drivers when they are close to running off the road.
Since 2005, Missouri traffic fatalities have declined 41 percent.
Of those killed in crashes last year, 63 percent were not wearing seatbelts as they were required to do.
