DUI Cases in Westminster
Westminster PD and Colorado State Patrol write a large share of the metro’s DUI cases along the US-36 corridor, plus Sheridan Boulevard, Federal Boulevard, Wadsworth Parkway, and the 88th, 92nd, and 104th Avenue crossings. Because the city straddles two counties, the location of your stop decides everything: arrests in the Adams County portion are prosecuted by the 17th Judicial District at the Adams County Justice Center, 1100 Judicial Center Drive, Brighton, CO 80601; arrests in the Jefferson County portion are prosecuted by the 1st Judicial District in Golden.
The two DA offices differ in plea posture, diversion availability, and trial readiness on refusal and marijuana cases. Daniel has defended DUI cases in both courthouses for over nineteen years and adapts strategy to the venue. Some city-ordinance traffic matters are heard at Westminster Municipal Court, 3030 Turnpike Drive, Westminster, CO 80030.
OverviewThe Seven-Day DMV Deadline Applies Either Way
Whichever county the criminal case lands in, the DMV express-consent action runs on its own clock: seven days from the Notice of Revocation to request a hearing. That hearing is often the defense’s first chance to question the arresting Westminster officer under oath.
Defense StrategyHow Daniel Defends Westminster DUI Cases
- The stop: Was there reasonable suspicion for the initial contact — or a pretext?
- The roadside: Were maneuvers instructed and scored to NHTSA standards, on suitable terrain, on camera?
- The chemical test: Intoxilyzer 9000 operator certification, blood-draw chain of custody, and the two-hour statutory window
- The disclosure: Calibration logs, maintenance records, and body-worn-camera footage, produced on time
The venue: Adams and Jefferson County prosecutors handle refusal and THC cases differently — the defense should too. Adams County prosecutors are consistently aggressive on refusal and marijuana-DUI cases. Daniel has tried and won both at the Brighton courthouse — a 2025 not-guilty verdict on a marijuana DUI with a blood result at twice the per-se limit, and a 2024 not-guilty on a refusal DUI. See past results. Past results do not guarantee future outcomes.
Common QuestionsFrequently Asked Questions
Will my Westminster DUI go to Adams County or Jefferson County?
The location of the stop controls, not your home address. Roughly, the newer northern and eastern sections sit in Adams County and the southwestern sections in Jefferson County. Daniel confirms venue from the charging documents on day one.
Where is Westminster Municipal Court?
3030 Turnpike Drive. City-ordinance matters can be heard there; state DUI/DWAI charges proceed in county court.
Does the county change my defense?
It can. Diversion availability, plea posture on refusal cases, and courtroom logistics differ between the 17th and 1st Judicial Districts.
