Westminster DUI Lawyers — DUI and DWAI Defense Across Adams and Jefferson Counties
A DUI arrest in Westminster sets two legal processes in motion at once — a criminal case in either Adams or Jefferson County District Court depending on where the stop occurred, and a civil license revocation proceeding with the Colorado Department of Revenue. Westminster’s major corridors — US-36, Wadsworth Boulevard, Sheridan Boulevard, and the US-36/I-25 interchange — are among the most actively patrolled DUI enforcement zones in the north Denver metro. The Colorado State Patrol, Westminster Police Department, Adams County Sheriff, and Jefferson County Sheriff all conduct DUI enforcement in different parts of Westminster, and the agency that makes the arrest affects where the criminal case is filed. Burnham Law’s Westminster DUI attorneys defend both the criminal case and the DMV proceeding from the moment of arrest.
Meet our Westminster criminal defense team below — attorneys experienced in DUI and DWAI defense in both Adams County and Jefferson County District Courts.

DUI Law in Colorado
Colorado distinguishes between DUI — substantial impairment of the ability to safely operate a vehicle — and DWAI, which requires impairment to the slightest degree. A BAC of 0.08 or above creates a legal presumption of DUI. A BAC between 0.05 and 0.08 can support DWAI. Colorado also has a per se THC blood concentration threshold of 5 nanograms per milliliter for marijuana-impaired driving. Colorado’s expressed consent law requires drivers lawfully arrested for DUI to submit to chemical testing; refusal triggers automatic license revocation and can be used as consciousness of guilt evidence at trial.
DUI penalties escalate significantly with prior convictions. A first offense carries 5 days to one year in county jail (with probation eligibility), fines up to $1,000, 9 months to 2 years license revocation, and mandatory public service. A third DUI in Colorado is a Class 4 felony. Fourth and subsequent DUIs are also felonies. The 7-day deadline to request a Colorado DMV hearing runs from the date of arrest — not from any subsequent court date. Missing it results in automatic license revocation.
Westminster DUI cases present a jurisdictional wrinkle that attorneys without dual-county experience sometimes miss. A stop on the US-36 westbound lanes near Wadsworth may be in Jefferson County; the same highway a mile east may be in Adams County. A stop on Wadsworth south of 120th may be Jefferson County; north of certain points it may be Adams County. The arresting agency — CSP, Westminster PD, or a county sheriff — and the specific location of the stop determine where the criminal case is filed. We identify the correct jurisdiction immediately and take the first steps in both proceedings without delay.
What Our Westminster DUI Attorneys Challenge
The traffic stop: Law enforcement must have reasonable articulable suspicion to initiate a stop. US-36 and I-25 corridor stops in Westminster sometimes involve extended investigations that raise constitutional issues beyond the initial traffic stop justification. We scrutinize every Westminster DUI stop — whether made by Colorado State Patrol on the highway or Westminster Police in the city — for constitutional defects that require suppression of all evidence flowing from the stop.
Field sobriety tests: The standardized FSTs have real limitations. Westminster’s roadside conditions — busy highway shoulders on US-36, uneven commercial parking lots, traffic noise affecting test administration — can all affect the reliability of FST results. Medical conditions, anxiety, age, and officer administration errors further affect reliability. We challenge FST administration and interpretation in every Westminster DUI case.
Breath test results: Breathalyzer machines used by Westminster Police Department and both county sheriff’s offices must be properly calibrated and maintained. We obtain calibration and maintenance records for every device used in Westminster DUI stops and challenge results when those records reveal deficiencies.
Blood test results: Chain of custody, storage conditions, laboratory methodology, and analyst qualifications all affect the reliability and admissibility of blood test results. We review complete chain of custody documentation and request independent testing of preserved blood samples when appropriate.
Jurisdiction and filing accuracy: Cases filed in the wrong county — a Westminster DUI charged in Jefferson County when the stop occurred in Adams County, or vice versa — present jurisdictional challenges that experienced defense counsel identifies and raises appropriately.
The DMV hearing: The 7-day deadline to request a DMV hearing runs from the arrest date. We request this hearing immediately upon being retained — before any other action in the defense process.
How Westminster DUI Cases Work
A DUI arrest in Westminster results in booking — typically at the Westminster Police Department or the appropriate county jail depending on the arresting agency — and an initial advisement in the appropriate county district court within 48 hours. The 7-day clock for requesting a DMV hearing begins running from the date of arrest, independent of any court date. Our first action on every Westminster DUI case is to request the DMV hearing and preserve the client’s driving privileges pending both proceedings.
In the criminal case, the defense focus in the first weeks is on obtaining all evidence — the dashcam and body camera footage, the chemical test records, the officer’s training records, and the calibration documentation for the testing device. The quality and content of this evidence determines the strength of suppression and challenge motions. Cases with significant suppression issues often resolve with reduced charges or dismissal. Cases without viable suppression issues are evaluated for other defenses, including challenges to the reliability of the specific test results.
Westminster DUI cases in Adams County are handled by the 17th Judicial District DA’s office; those in Jefferson County by the 1st Judicial District. Each office has its own approach to DUI cases — their charging practices, their plea negotiation tendencies, and their positions on diversion for first-offense DUI defendants differ in ways that experienced local counsel navigates effectively. The defense strategy that produces the best outcome in one county may need adjustment for the same charge in the other.

Frequently Asked Questions — Westminster DUI
Which county handles a Westminster DUI?
Which county handles a Westminster DUI depends on where the stop occurred. Westminster straddles the Adams-Jefferson county line, and the county court that handles the case is determined by the specific location of the traffic stop. Stops on US-36 and areas north and east of the county line generally fall in Adams County (17th JD); areas south and west generally fall in Jefferson County (1st JD). The arresting agency can provide a clue, but the specific location of the stop is the determining factor. We identify the correct jurisdiction immediately in every Westminster DUI case.
What is the difference between DUI and DWAI in Colorado?
DUI requires proof of substantial impairment — the driver was substantially incapable of safely operating a vehicle. DWAI requires proof of impairment to the slightest degree, carries lesser penalties, but still results in a criminal conviction and license points. A BAC of 0.08 or above creates a presumption of DUI; between 0.05 and 0.08 can support DWAI. Negotiating a first-offense DUI down to DWAI makes a meaningful difference in both immediate consequences and long-term record impact.
What happens to my license after a DUI arrest in Westminster?
After a DUI arrest in Westminster, the arresting officer confiscates your license and issues a temporary driving permit valid for 7 days. Within those 7 days, you must request a DMV hearing to contest the revocation or your license is automatically revoked when the permit expires. If you timely request the hearing, driving privileges are preserved pending the outcome. An interlock restricted license may be available during any revocation period, allowing limited driving with an ignition interlock device installed.
Is a DUI stop on US-36 in Westminster a federal highway stop?
No — US-36 through Westminster is a state highway, and DUI stops on US-36 are conducted under Colorado law by Colorado State Patrol, Westminster Police, and county sheriff’s deputies. The constitutional standards for the stop, the field sobriety testing, and the chemical testing are all governed by Colorado law and the Fourth Amendment, just as with any other Westminster DUI stop. The arresting agency — CSP versus local police — can affect procedural details but does not change the fundamental legal framework for the defense.
How long does a DUI stay on my record in Colorado?
DUI and DWAI convictions in Colorado cannot be sealed and remain on the criminal record permanently. Prior DUI and DWAI convictions can be used to enhance subsequent charges to felony level with no time limit on how old the prior is. This permanence makes aggressive defense at the time of arrest — rather than accepting a plea to resolve the case quickly — critically important for Westminster residents. A DUI conviction on a Colorado record follows you indefinitely.
