The number of people killed in Michigan traffic fatalities this year has eclipsed 1,000 for the first time since 2007, the most recent statistics show.

The 1,009 deaths the Michigan Department of Transportation has recorded this year through Dec. 13, 2016, mark a nine-year high when compared to Michigan State Police yearly totals:

1,009 fatalities in 2016 through Dec. 13

876 in 2014

951 in 2013

936 in 2012

889 in 2011

937 in 2010

871 in 2009

An improved economy and lower gas prices leading to more vehicle miles driven is part of the rising traffic fatalities in Michigan and nationwide, Michigan State Police Office of Highway Safety Planning Spokeswoman Anne Readett said.

"The Office of Highway Safety Planning is continuing to support efforts that are proven to reduce traffic deaths and serious injuries: improving seat belt use and reducing impaired driving," she said.

Alcohol-involved fatalities increased 28 percent from 2014 to 2015 and drug-involved traffic deaths increased 19 percent during that same period in Michigan, she said.

Final numbers and details about 2016 are expected to be released sometime in the first part of 2017.

Research is needed to determine the factors contributing to the rise, Michigan State Police Spokeswoman Shanon Banner said.

"...but in the meantime we continue to stress the personal responsibility of driving and the role each of us can play in limiting crashes by being attentive to the main task of driving. Put down your phone, avoid distractions behind the wheel and say no to impaired driving," Banner said.

The MSP and OHSP urge drivers to be safe with messages posted on social media on topics of winter weather, distracted driving and driving impaired.
