DUI & DWI Defense in Denver, Colorado

A DUI or DWAI charge in Colorado carries consequences that extend far beyond the courtroom. A conviction can result in jail time, heavy fines, license revocation, and a permanent criminal record that affects your employment, housing, and reputation. Whether this is your first arrest or you are facing enhanced penalties for a subsequent offense, the decisions you make in the days following your charge will shape the outcome of your case.

Types of DUI & DWAI Charges in Colorado

Colorado law distinguishes between several impaired driving offenses. DUI (Driving Under the Influence) applies when a driver’s BAC is 0.08% or higher, or when the driver is substantially incapable of safely operating a vehicle due to alcohol or drugs. DWAI (Driving While Ability Impaired) carries a lower threshold of 0.05% BAC and reflects that the driver’s ability was affected to the slightest degree. DUI per se charges are based solely on chemical test results, while aggravated DUI applies at BAC levels of 0.15% or higher and carries enhanced penalties. Colorado also enforces strict underage DUI laws with a BAC limit of just 0.02% for drivers under 21.

Penalties and Consequences

First-offense DUI in Colorado can result in up to one year in jail, fines up to $1,000, up to 96 hours of community service, and a nine-month license revocation. Subsequent offenses escalate dramatically — a fourth DUI is charged as a Class 4 felony under C.R.S. 42-4-1301, carrying two to six years in prison. Beyond criminal penalties, you face mandatory alcohol education classes, probation, increased insurance premiums, and the installation of an ignition interlock device on your vehicle. A DUI conviction remains on your Colorado driving record permanently.

Defense Strategies

Effective DUI defense begins with scrutinizing every element of the stop, arrest, and testing process. Our attorneys challenge cases on multiple fronts:

• Illegal traffic stops — Law enforcement must have reasonable suspicion to initiate a stop. If the officer lacked proper justification, all evidence obtained may be suppressed.
• Breathalyzer and chemical test challenges — Breath testing devices require precise calibration and maintenance. We examine device records, operator certifications, and testing protocols to identify errors that undermine results.
• Field sobriety test reliability — Standardized field sobriety tests are inherently subjective and affected by medical conditions, fatigue, footwear, road conditions, and officer bias.
• Rising BAC defense — Alcohol absorption continues after you stop drinking. Your BAC at the time of testing may have been higher than your BAC at the time of driving.
• DMV hearing representation — You have only seven days after a DUI arrest to request a hearing with the Colorado DMV to contest your license revocation. Missing this deadline results in automatic suspension.
