The U.S. Department of Transportation’s National Highway Traffic Safety Administration today announced its latest estimate of traffic deaths, which show a steep 9.3 percent increase for the first nine months of 2015. The news comes as the agency kicks-off its first in a series of regional summits with a day-long event in Sacramento, Calif., to examine unsafe behaviors and human choices that contribute to increasing traffic deaths on a national scale. Human factors contribute to 94 percent of crashes according to decades of NHTSA research.

“For decades, U.S. DOT has been driving safety improvements on our roads, and those efforts have resulted in a steady decline in highway deaths,” said U.S. Transportation Secretary Anthony Foxx. “But the apparent increase in 2015 is a signal that we need to do more. The safety summits that NHTSA is kicking off today in Sacramento will provide us with new approaches to add to the tried-and-true tactics that we know save lives.”

NHTSA estimates that more than 26,000 people died in traffic crashes in the first nine months of 2015, compared to the 23,796 fatalities in the first nine months of 2014. U.S. regions nationwide showed increases ranging from 2 to 20 percent. View the report
