Extreme DUI Attorney in Arapahoe County

Personal Defense Against High-BAC Charges in Arapahoe County, With 25+ Years in Colorado Courts

An Extreme DUI charge in Colorado isn’t just a more serious label for the same offense. Under C.R.S. 42-4-1301, a blood alcohol content (BAC) of 0.15% or higher triggers a legally distinct charge with its own penalty tier, its own mandatory minimums, and consequences that begin before you ever set foot in the Arapahoe County Justice Center. I’m Joseph Lazzara, and I handle every Extreme DUI case personally. No paralegal, no associate. You get direct access to an attorney with 25+ years of Colorado criminal defense experience from the first call to the final resolution.

Time matters immediately after an Extreme DUI arrest. Call (303) 429-6200 to schedule your free consultation and help protect your right to a DMV hearing before the 7-day deadline expires.

What Separates an Extreme DUI from a Standard DUI in Colorado

Most people know that a BAC of 0.08% or higher supports a DUI charge. What many don’t realize is that Colorado law creates a second, harsher tier once that number reaches 0.15%. At that threshold, the law automatically applies the Persistent Drunk Driver (PDD) designation, a classification that treats even a first-time offender as though they have prior DUI history.

The PDD designation carries consequences that extend well beyond the courtroom:

• Ignition interlock device (IID) requirement: Installation is mandatory for a minimum of two years, longer than what applies to a standard DUI conviction.
• Mandatory jail time at 0.20% BAC: If your BAC reached 0.20% or higher, C.R.S. 42-4-1307 requires a minimum 10-day jail sentence, though the court retains discretion to apply certain sentencing alternatives.
• Compounding future exposure: Any subsequent alcohol-related offense is treated as a repeat offense, making the long-term stakes higher than the current charge alone suggests.
• Felony escalation: A first offense is typically a misdemeanor, but the charge can become a felony when aggravating factors are present, including three or more prior convictions for DUI, DUI per se, DWAI, or qualifying vehicular offenses.

Two Legal Battles Running at the Same Time

An Extreme DUI arrest in Arapahoe County launches two simultaneous proceedings. The criminal case moves through the 18th Judicial District at the Arapahoe County Justice Center in Centennial. At the same time, the Colorado Department of Revenue’s Division of Motor Vehicles initiates an administrative license revocation through the Express Consent process. These run on separate tracks with separate deadlines.

You have exactly 7 calendar days from the date of arrest to request a DMV Express Consent hearing. Missing that window means automatic license revocation, regardless of how the criminal case turns out. For an Extreme DUI, the DMV revocation period and IID requirement are more severe than for a standard DUI, which makes defending the administrative track as important as defending the criminal one. I handle both.

How I Challenge Extreme DUI Evidence

High BAC results feel definitive on paper. They aren’t always reliable in practice. My defense work draws on a network of forensic toxicologists, private investigators, and other professionals I’ve built over more than two decades of trial work. I’m also certified in Colorado Standardized Field Sobriety Tests through the same training program that certifies law enforcement officers statewide, which means I know exactly what officers are required to do and where their administration can be challenged.

Common defense angles in Extreme DUI cases include:

• BAC test accuracy: Breathalyzers must be properly calibrated and maintained; blood testing equipment and procedures must follow strict protocols. Failures in either can undermine the result.
• Legality of the traffic stop: An officer must have reasonable suspicion before initiating a stop. Evidence gathered without it may be subject to suppression.
• Field sobriety test administration: NHTSA-standardized procedures must be followed precisely. Deviations by the officer can create grounds to challenge the observations recorded.
• Blood evidence chain of custody: Refrigeration, handling, and laboratory procedures are all subject to scrutiny. A break in that chain can call results into question.

I prepare every case as if it’s going to trial. No issue goes unaddressed, and no potential challenge goes unexamined.
