DUI Cases in Denver
Denver is the only consolidated city-and-county in Colorado, and it operates its own court system distinct from the state county-court structure. Most misdemeanor DUI/DWAI charges are heard in Denver County Court; felony DUI, vehicular assault, and vehicular homicide cases proceed in the Denver District Court at the Lindsey-Flanigan Courthouse, 520 W Colfax Avenue, Denver, CO 80204. Denver makes up the entire 2nd Judicial District.
Denver Police, Colorado State Patrol, and University of Colorado / Auraria campus police all charge DUIs into the Denver courts. Stops cluster on I-25, I-70, I-225, US-6 (6th Avenue), Colfax, Speer, Federal, Broadway, and the LoDo / RiNo entertainment corridors. Late-night stops outside ballparks, concert venues, and bars are common, as are stops on holidays at sobriety checkpoints.
Daniel's recent Denver work includes a 2024 not-guilty jury verdict on a DUI charge with a breath test of .110 — well above the per-se 0.08 limit. He also obtained a 2024 dismissal of a Denver third-degree assault / domestic violence case that was later sealed.
OverviewHow a Denver DUI Starts: Two Cases at Once
A Denver DUI arrest triggers two parallel proceedings: a criminal case in Denver County or District Court, and a civil express-consent revocation before the Colorado Division of Motor Vehicles. Each has its own timeline, evidence standard, and strategy. Miss the DMV hearing window — just seven days from the date of your notice — and you may lose your license regardless of the criminal outcome.
Daniel H. Kyser handles both. He has defended Colorado DUI and DWAI charges in every metro-area county plus courts across the state, from Gunnison to Greeley, Fort Collins to Pueblo.
Types of Cases Handled
- First-offense DUI and DWAI (misdemeanor)
- Second and third DUI/DWAI (enhanced mandatory-jail cases)
- Felony DUI (fourth or subsequent conviction — C.R.S. § 42-4-1301)
- Underage drinking and driving (UDD)
- Marijuana and combined-drug DUI
- Prescription-medication impairment cases
- Refusal cases & implied-consent DMV hearings
- Vehicular assault & vehicular homicide
- Commercial driver (CDL) DUI and out-of-state license defense
Penalties at a Glance
Colorado's penalty scheme is driven by prior history and BAC. General ranges include:
- DWAI (1st): up to 180 days jail, up to $500 fine, 8 DMV points, possible probation and classes.
- DUI (1st): 5 days to 1 year jail (suspendable), $600–$1,000 fine, 9-month license revocation, interlock.
- DUI (2nd): 10 days mandatory jail (no suspension), 1-year license revocation, 2-year interlock, alcohol monitoring.
- DUI (3rd): 60 days mandatory jail, 2-year revocation, extended interlock, probation.
- Felony DUI: class 4 felony, 2–6 years prison presumptive (with mandatory aggravators possible).
Defense Strategies
A disciplined DUI defense attacks each link in the prosecution's chain:
- Stop: Was the initial traffic stop supported by reasonable suspicion?
- Investigation: Were roadside maneuvers properly instructed, performed on suitable terrain, and scored correctly under NHTSA standards?
- Arrest: Did the officer have probable cause — not just suspicion?
- Chemical test: Was the Intoxilyzer 9000 or blood draw conducted within the statutory two-hour window? Was the testing agency accredited? Were the operator certifications current?
- Disclosure: Did the prosecution timely disclose maintenance records, calibration logs, and officer body-worn camera?
Denver DUI Cases: Local Considerations
Denver's combined city-and-county structure creates two separate DUI paths. Denver County Court handles most DUI cases as misdemeanors; Denver District Court (2nd Judicial District) takes felony DUI prosecutions — fourth-and-up convictions under C.R.S. § 42-4-1301(1)(a), and DUI causing serious bodily injury or death. Both operate out of the Lindsey-Flanigan Courthouse complex at 520 W. Colfax Avenue.
Denver Police Department's DUI enforcement is concentrated on I-25, I-70, and major arterials including Colfax and Speer Boulevard. The department runs a dedicated DUI enforcement unit and consistently uses body-worn-camera footage from the initial stop through chemical testing. That footage is critical evidence in every defense — both for what it captures and for what it does not (uninstructed SFSTs, missing portions of the express-consent advisement, evidence of confusion or medical issue not reflected in the officer's report).
Denver runs one of the state's busiest DMV express-consent hearing operations. The seven-day deadline to request a hearing after a DUI arrest is non-negotiable; missing it forfeits the administrative case entirely, regardless of what happens in the criminal case. For many Denver DUI defendants, the DMV outcome is more consequential than the criminal-court outcome — particularly for CDL drivers, rideshare drivers, and anyone whose employment depends on a clean driving record.

Frequently Asked Questions
Where will my Denver DUI case be heard?
Most misdemeanor Denver DUI cases are heard in Denver County Court, which sits within the Lindsey-Flanigan Courthouse complex at 520 W Colfax Avenue. Felony DUI and vehicular cases proceed in Denver District Court (also at Lindsey-Flanigan). Denver is unique in Colorado as the only city-and-county that runs its own consolidated court system.
What is the difference between a DUI and a DWAI?
A DUI requires substantial impairment or a BAC of 0.08% or more. A DWAI is impairment "to the slightest degree," typically with a BAC between 0.05% and 0.079%. DWAI is a lesser offense but still carries jail, points, and probation exposure.
When does a DUI become a felony in Colorado?
A fourth or subsequent DUI/DWAI conviction is a class 4 felony under C.R.S. § 42-4-1301. DUIs involving serious bodily injury or death are separately charged as vehicular assault or vehicular homicide, which are always felonies.
Should I have refused the chemical test?
Colorado's express-consent law makes refusal a civil revocation (minimum one year). Whether refusal helped or hurt your case depends on the evidence — body cam, HGN results, and statements. Daniel reviews every angle to build the strongest defense available with what happened.
Can I keep driving with an interlock device?
In most first-offense cases, drivers can apply for an early reinstatement with an ignition-interlock device after an initial no-drive period. The specifics depend on BAC, refusal status, and prior history.
