In 2016, Colorado had its deadliest year of traffic fatalities in a decade. According to the Colorado Department of Transportation, 605 people died on state roadways last year. CDOT officials gave a number of reasons for the increase in traffic deaths, but it all comes down to drivers making poor choices. "We have a problem in Colorado. We have a problem across the country," said CDOT Executive Director Shailin Bhatt. Bhatt says speed and not buckling up were two things to blame for Colorado’s 605 traffic fatalities last year. That’s up from 547 in 2015.
