Tailgating, speeding, weaving through traffic—everyone has witnessed, experienced or even been guilty of road rage. New federal data reveals that, per capita, Colorado is second in the nation for deaths caused by road rage and aggressive driving. Almost one in 10 deadly car accidents in the state in 2016 were related to road rage.

Aggressive driving fatalities are back on A1 Colorado news after an incident in Westminster in June left one child dead and his mother and brother critically injured. Colorado State Trooper Gary Cutler talked to Colorado Matters about the state's road rage problem, and how to report aggressive driving when you see it.
