Fort Collins Driving Under the Influence Attorney: DUI vs. DWAI in Larimer County

Colorado recognizes two levels of impaired driving. A DUI (Driving Under the Influence) applies when a driver is substantially incapable of operating a vehicle safely due to alcohol, drugs, or both. A blood alcohol content (BAC) of 0.08% or higher creates a presumption of DUI.

A DWAI (Driving While Ability Impaired) is a lesser charge, applicable when a driver’s ability is impaired “to the slightest degree” even if not substantially. DWAI typically applies at a BAC between 0.05% and 0.08%, though it can be charged based on observed impairment alone, regardless of BAC.

While DWAI is often seen as the lesser offense, it’s still a criminal charge in Colorado, carrying fines, potential jail time, license points, and a permanent record.

Lawyer for DWAI Charges in Loveland: Colorado’s Express Consent Law

Colorado is an “express consent” state. Under C.R.S. § 42-4-1301.1, anyone who drives on Colorado roads has already agreed, by virtue of holding a license, to submit to chemical testing (breath or blood) if lawfully arrested for suspected impaired driving.

Refusing this test carries serious consequences separate from the criminal case itself. A refusal typically triggers an automatic driver’s license revocation through the Colorado DMV, and prosecutors can use the refusal as evidence of guilt in court. Unlike the criminal case, license revocation for refusal proceeds through an administrative hearing, which is a separate track with its own strict deadlines.
