DUI Cases in Arapahoe County
Most Arapahoe County DUI cases are filed at the Arapahoe County Justice Center, 7325 S Potomac Street, Centennial, CO 80112. The Aurora Municipal Court at 14999 E Alameda Pkwy handles many Aurora DUIs charged under city ordinance, while state-charge cases proceed to the Justice Center. Daniel's law office is located at 5950 S Willow Drive in Greenwood Village — a short drive from the courthouse and from most of the cities the 18th Judicial District covers.
Stops cluster along I-25, I-225, E-470, C-470, Arapahoe Road, Parker Road, Hampden Avenue, and the busy Aurora corridors near Mississippi and Alameda. Aurora Police, Centennial-contracted patrol, Englewood Police, Littleton Police, Greenwood Village Police, the Arapahoe County Sheriff, and Colorado State Patrol all charge DUIs into this courthouse.
How an Arapahoe County DUI Starts: Two Cases at Once
An Arapahoe County DUI arrest triggers two parallel proceedings: a criminal case in Arapahoe County Court, District Court, or Aurora Municipal 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)

- 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?
Arapahoe County DUI Cases: Local Considerations
Arapahoe County's DUI docket runs through the Arapahoe County Justice Center in Centennial. After the 2025 judicial-district split, the 18th Judicial District now covers Arapahoe County alone — and the DA's office is recalibrating staffing, charging standards, and trial calendars for the smaller-but-denser configuration that followed the split.
Aurora's traffic enforcement is particularly active along I-225 and Colfax. Aurora Police Department brings a high volume of DUI arrests, many involving combined drug-and-alcohol allegations or marijuana DUI under Colorado's permissive-inference statute for blood-THC concentrations of 5 ng/mL or above (C.R.S. § 42-4-1301(6)(a)(IV)). That permissive inference is exactly what its name suggests — a presumption the defense can rebut on scientific and procedural grounds, particularly given the lag between roadside detection and the blood draw.
DUI cases from Centennial, Englewood, Littleton, Greenwood Village, and Cherry Hills Village are also filed at the Centennial courthouse. Some Aurora and Englewood matters originate as municipal-court filings instead of state-court DUIs — a forum choice that carries different procedural rights and a different sentencing posture, and one that the defense can sometimes influence.
Your First 30 Days After an Arapahoe County DUI Arrest
Days 1–7: The clock that matters most is the DMV's. You have seven days from your Notice of Revocation to request an express-consent hearing — miss it and the license revocation takes effect regardless of what happens in court. Request the officer's presence at the hearing, and talk to an attorney before deciding anything else.
Days 7–21: Your first court appearance (advisement) is set at the Arapahoe County Justice Center. Defense work starts now: preserving body-worn-camera footage, requesting dash camera video, obtaining the stop report, and — in breath cases — pulling Intoxilyzer 9000 maintenance and certification records before they go stale.
Days 21–30: With discovery in hand, the suppression review begins: was the stop lawful, were the roadside maneuvers properly administered, was the chemical test conducted within the statutory window? The answers shape everything that follows — plea posture, DMV strategy, and whether this is a case to try.

Frequently Asked Questions
Where will my Arapahoe County DUI case be heard?
Most state-law DUI charges from Arapahoe County are filed at the Arapahoe County Justice Center at 7325 S Potomac Street in Centennial. Misdemeanor DUI/DWAI charges are typically heard in Arapahoe County Court; felony DUI and vehicular cases proceed in Arapahoe County District Court. Aurora-charged DUIs under city ordinance go to Aurora Municipal Court at 14999 E Alameda Parkway. Englewood, Littleton, and Centennial have municipal courts that may handle related traffic matters.
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.
How long does a DUI case take in Arapahoe County?
Most Arapahoe County misdemeanor DUI cases resolve in three to six months from first appearance to plea or trial setting. Blood-draw cases run longer while lab results are pending, and the 18th Judicial District's post-split recalibration means trial calendars are still settling — contested cases can extend beyond six months. The DMV track is faster and unforgiving: seven days to request your express-consent hearing.
Do I need a local Arapahoe County DUI attorney?
You need an attorney who regularly appears at the Arapahoe County Justice Center and knows the 18th Judicial District's current charging and plea standards — which have been shifting since the district split. Daniel's office sits in the Denver Tech Center minutes from the Centennial courthouse, and Arapahoe County is one of his highest-volume DUI venues, with recent felony-DUI charges negotiated down to misdemeanor outcomes.
My DUI was in Aurora — is that Arapahoe County?
Usually, yes. Most of Aurora lies within Arapahoe County, so state-law DUI charges from Aurora Police stops are typically filed at the Arapahoe County Justice Center in Centennial. Portions of Aurora extend into Adams County, and Aurora also operates a municipal court for city-ordinance matters — so check your summons carefully. The charging document controls where you appear, and the answer changes which DA's plea practices apply to your case.
