Denver (AP) - A Denver Post analysis has found that about 10,000 drunken drivers arrested in Colorado each year are repeat offenders.
Police arrest roughly 31,000 drunken drivers a year, so about one in three has at least one previous DUI.
The Post examined records of arrests made from 2005 to 2007.
From 2005 to 2007, an average of 31,011 suspected drunken drivers were arrested each year in Colorado, according to statistics from the Colorado Bureau of Investigation.
An average of 10,835 drunken drivers each year had at least one prior DUI arrest, according to division of behavioral health data from probation-department evaluations of drivers facing DUI charges.
Jefferson County District Attorney Scott Storey says getting drunken drivers off the road for good is a constant struggle.
