Drivers in Colorado racked up 53.7 drunken driving arrests for every 10,000 residents in 2014, or more than 28,000 DUIs. Its drunken driving fatality rate reflected the national average, with 3 deaths per 100,000 residents, or 160 in 2014.
Until 2015, Colorado was one of only five states without a felony DUI law, which limited jail time, even for serial drunk drivers, to one year.
After a repeat offender killed a father and two young boys, Coloradoans passed a law classifying a fourth DUI conviction in one's lifetime a felony, punishable by up to six years in prison. Drivers busted for DUI in Colorado will see annual car insurance rates go up an average of 52 percent.
