The death toll on America’s roadways continues to increase. The National Highway Traffic Safety Administration estimates 31,720 people died in motor vehicle crashes in the U.S. through the first nine months of 2021, the agency announced Tuesday.

The 2021 increase compared with the same time period in 2020 represents the highest number of deaths during the first nine months of a year since 2006. It is also the highest percentage increase for a year’s first nine months since the Fatality Analysis Reporting System was first initiated in 1975.

The 12% increase in fatalities correlates with a 11.7% increase in vehicle miles traveled during the same time period. Almost every region in the country experienced increases, except for Kentucky, West Virginia, Virginia, North Carolina, Delaware and Washington, D.C., which experienced a 2% decline.

The Westernmost portion of the U.S. saw some of the highest increases, with the region that includes California, Arizona and Hawaii seeing a 17% increase in fatalities and the region including Oregon, Washington, Idaho and Montana experiencing a 20% increase, NHTSA said.
