Former-Prosecutor DUI Defense for Your Criminal Case & Driving Privileges

A DUI, DWAI, or DUID arrest can create two connected proceedings: a criminal case and a separate administrative matter involving your driving privileges. The immediate steps depend on the alleged offense, breath or blood test results, refusal status, prior history, and deadlines in the paperwork you received.

We defend clients in DUI-related cases throughout Jefferson, Douglas, Arapahoe, and El Paso Counties. As a former prosecutor, Attorney Bresee understands how impaired-driving cases are investigated and how the government evaluates evidence.

Call (303) 747-4032 or reach us online for a complimentary in-office or virtual consultation with our Denver DUI defense attorney. We’re available 24/7.

DUI Defense Strategies in Denver

We review the stop, the investigation, the testing process, and any related DMV issues. Attorney Bresee’s former-prosecutor background helps us assess how law enforcement and prosecutors built the case, where the evidence may be vulnerable, and which issues require further investigation.

The Colorado Express Consent process is separate from the criminal case and may move on a shorter timeline. A DMV license hearing generally must be requested within seven days in specified breath-test or refusal situations, or within seven days after notice of qualifying blood-test results. The test type, notice, paperwork, and current Colorado DMV rules control the applicable deadline.

Our evidence review may address:

Whether police officers had reasonable suspicion or another lawful basis to stop you
Whether probable cause supported the arrest
How breath or blood testing was administered, documented, and handled
Whether field sobriety observations match body-camera footage and police reports
Whether law enforcement followed required procedures and constitutional protections

We use that review to develop a defense strategy based on the evidence and circumstances. Depending on the case, the strategy may involve negotiations, motions challenging evidence, preparation for trial, or a combination of those steps.

We defend DUI-related charges and refusal matters involving:

First-time DUI, DWAI, and DUID offenses
Repeat or felony DUI cases
DUI per se allegations based on alcohol-concentration evidence
Underage drinking and driving (UDD)
Refusal to submit to a breath or blood test

DUI Consequences & Choosing Defense Counsel

Depending on the charge, prior history, test evidence, court disposition, and administrative driving record, a drunk driving allegation can involve criminal penalties and separate license consequences.

Potential DUI Consequences

Potential requirements and consequences may include:

Jail or other court-imposed sentencing conditions
License suspension or revocation
Probation and alcohol education
Fines and court costs
Installation of an ignition interlock device

A conviction or administrative action can also affect insurance, employment, professional licensing, education, housing, and daily transportation. The significance of each concern depends on the offense, the outcome of the criminal case, and the driver’s circumstances.

Choosing a DUI Defense Attorney

Our practice is focused on criminal defense, including DUI defense. Attorney Bresee is a former Colorado prosecutor who has handled thousands of criminal matters and tried hundreds of jury cases. His courtroom experience informs how we investigate the evidence, evaluate negotiations, prepare motions, and approach trial when appropriate.

Attorney Bresee received a Distinguished peer-reviewed rating from Martindale-Hubbell in 2026. That rating reflects peer assessment of legal knowledge, judgment, communication, capability, and experience.

When choosing a DUI defense attorney, consider whether counsel can address both the criminal case and the separate driving-privilege issue, explain the evidence, and prepare beyond an early negotiation.

Understanding Colorado DUI Laws

Colorado DUI law (C.R.S. § 42-4-1301) distinguishes among several alcohol- and drug-related driving allegations. The charge and available defenses depend on the alleged level of impairment, the prosecution’s legal theory, test evidence, and documented police observations.

The main allegations include:

DUI: Driving when alcohol, drugs, or a combination of substances allegedly affects a person to a degree that they’re substantially incapable of safely operating a vehicle
DUI per se: Driving with an alcohol concentration at or above the statutory threshold within the period addressed by Colorado law
DUID: Driving under the influence of drugs, which may involve marijuana, prescription medication, or controlled substances
DWAI: Driving while ability impaired to the slightest degree by alcohol, drugs, or both

Colorado’s Express Consent law governs chemical testing and related administrative license issues.

The Colorado DUI Legal Process

The specific steps depend on the charge, prior history, evidence, procedural issues, and deadlines in the driver’s paperwork.

The process may include:

DMV or Express Consent hearing: A timely hearing request may allow the driver to contest an administrative action. We can represent clients in this separate proceeding.
Arraignment or advisement: The court addresses the pending charge, rights, and future dates.
Discovery review: We examine police reports, body-camera footage, witness information, breath or blood results, and field sobriety testing.
Pretrial motions: Legal issues may include the stop, probable cause, testing procedures, statements, and constitutional violations.
Negotiation or trial: Some cases resolve through negotiation, while others require trial preparation and courtroom litigation.
Sentencing: If there is a conviction, the court determines the sentence under the applicable law and facts.

At Law Offices of M. Colin Bresee, we draw on Attorney Bresee’s former-prosecutor perspective and experience trying hundreds of jury cases to examine both proceedings and prepare for negotiation or trial when appropriate. You can message our firm online to request case-specific advice.
