DENVER -- There has been an increase in traffic deaths in Colorado.
The Colorado Department of Transportation said Tuesday that fatalities went up 10 percent during 2015. There were 545 deaths on Colorado highways.
The spike is alarming because so many of the deaths could have been prevented.
Half of those killed were not wearing seat belts. Another third of the deaths in traffic crashes are related to drunk or drugged driving, CDOT said.
In all, 104 people died in motorcycle crashes, with many of them not wearing helmets.
Authorities are researching the statistics in order to come up with plans to reduce the number of traffic fatalities.AlertMe
