Evidential Breath Alcohol Testing

Intoxilyzer 9000 (I-9000)

The Intoxilyzer 9000 (I-9000) is the evidential breath alcohol testing instrument used by law enforcement agencies in Colorado to determine whether a person is driving under the influence of alcohol.


The instrument measures a person's breath alcohol content, expressed in grams of alcohol per 210 liters of breath.

 The results from the I-9000 have been proven to be scientifically accurate and precise. Results generated by the I-9000 are used for the state's prosecution of DUI/DWAI offenses.


In Colorado, it is a misdemeanor for any person to drive a vehicle while under the influence of alcohol or drugs or both (driving under the influence, DUI) or while impaired by alcohol or drugs or both (driving while ability impaired, DWAI).


The rules governing the DUI/DWAI program in Colorado are the Rules Pertaining to Testing for Alcohol and Other Drugs (5 CCR 1005-2). These rules are established by the Colorado Department of Health
and Environment and approved by the Colorado Board of Health.
