Understanding DUI in Colorado
Colorado law sets the legal blood alcohol concentration (BAC) limit at 0.08%. But even a BAC between 0.05% and 0.08% can trigger a DWAI charge, while drivers under 21 with a BAC as low as 0.02% face zero‑tolerance penalties. If you've been pulled over:
Express Consent Law means refusing a chemical test may lead to administrative sanctions.
Standard penalties include fines from $600 to $1,500, court‑mandated alcohol education, license suspension, and possible jail time—especially if your BAC was 0.20% or higher, or if it's a second or third DUI.
Why Hiring a Denver DUI Defense Attorney Matters
Legal Expertise Tailored to DUI Cases
As a seasoned Denver dui defense attorney firm, MBS attorneys specialize in DUI/DWAI law. We can help deconstruct breathalyzer reports, question field‑sobriety testing protocols, and challenge the prosecution’s case every step of the way.
Protecting Your Constitutional Rights
From the moment of your traffic stop, our team ensures your rights are upheld. We'll evaluate whether law enforcement followed proper procedure and learn if evidence was obtained illegally. Any misstep may provide grounds to suppress evidence or dismiss the case altogether.
Evidence Review & Expert Resources
We partner with forensic specialists to analyze Intoxilyzer data, blood sample handling, and error rates—providing you with a defense built on science and scrutiny.
Skilled Courtroom Representation
Whether negotiating with prosecutors or standing before a jury, our DUI attorneys bring trial experience that can make a difference. We’re well-versed in plea negotiations and adversarial courtroom strategy.
Zero-Tolerance & Marijuana DUI Cases
Even though recreational marijuana is allowed in Colorado, driving under the influence of THC remains illegal. Possessing more than five nanograms of active THC per milliliter of blood can lead to charges. Unlike alcohol, there’s no universally accepted “legal limit,” making it possible to challenge the evidence.
For underage drivers, a BAC of just 0.02% could mean automatic license revocation. Our attorneys know how to protect minors’ rights under these strict rules.

First‑time DUI or DWAI
High‑BAC DUI (.20% or more)

FAQs
Can I still get a DUI if I tested under 0.08% BAC?
Yes. Colorado may still charge you with a DWAI if impairment is visible. Likewise, zero‑tolerance laws apply to drivers under 21—even with a BAC as low as 0.02%.
What if I refused a chemical test?
Refusing a test leads to automatic administrative penalties. Our attorneys challenge whether the officer properly advised you of those consequences and whether consent was lawfully invoked.
What about marijuana DUIs?
Since Colorado lacks a shelf‑set limit, prosecution must show actual impairment. That opens a path for defense arguing inaccurate testing, low THC levels, or lack of impairment.
