The DUI Law in Colorado
Drunk driving is charged as DUI in Colorado, at a blood alcohol level of 0.08 or more; driving while ability impaired (DWAI) is charged from 0.05.
Driving in Colorado is consent to a breath or blood test when an officer has cause to suspect DUI; the license case that follows a refusal or a failed test is run by the Division of Motor Vehicles, separately from the criminal case.

The Court Case
The District Attorney files the charge, and the case is heard in the County Court.

Colorado has no single public index of every trial court case; each court's records are looked up through that court.
The License Case
The court case is only half the record. The Division of Motor Vehicles runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Colorado Division of Motor Vehicles keeps the driving record the conviction goes on.
The Records a DUI Leaves
- The arrest report: from the agency that made the arrest, under the Colorado Open Records Act.
