Driving under the influence is a serious charge in Colorado, but it becomes even more serious if you have multiple convictions on your record. Once you reach a fourth DUI, the potential penalties become very steep because under Colorado law a fourth DUI is a felony crime.
With the passage of HB-17-1288, everyone convicted of felony DUI in Colorado will now have to go to jail. Governor John Hickenlooper signed the bill on June 6, 2017, and the law goes into effect on August 9, 2017. From that date forward, anyone who is convicted of a fourth or subsequent DUI will have to serve between 90 to 180 days in county jail with no time off for good behavior.
