The Patrol said fatalities are down 41 percent since 2005.
The count for 2013 ended with 741 traffic fatalities. That number is down from 1,257 fatalities in 2005.
The Highway Patrol has seen a steady drop in the number of traffic-related deaths since 2005, with the exception of 2012. That year saw a slight increase.
"This is an important trend that the Patrol would like to see continue," said Col. Ron Replogle. "Every trooper is committed to working with other agencies to further reduce the number of traffic deaths in our state. We believe education and enforcement encourage safe driving, which results in fewer traffic fatalities. I want to thank the public for helping to make this year safer than last year."
The total number of traffic crashes is also down 21 percent from 2005 to 2012.
