A Colorado DWAI — Driving While Ability Impaired — is the state’s lesser impaired-driving charge, and it applies when alcohol, drugs, or both diminish your ability to drive “to the slightest degree.” It kicks in at a lower blood alcohol level than a DUI: a BAC between 0.05% and 0.08% can support the charge, and prosecutors don’t even need a chemical test result if other evidence of impairment exists.1Justia. Colorado Code 42-4-1301 – Driving Under the Influence – Driving While Impaired – Driving With Excessive Alcoholic Content – Definitions – Penalties A first offense carries up to 180 days in jail. A fourth becomes a felony. And because Colorado cannot seal or expunge a DWAI conviction, the record follows you for life.
How Colorado Defines DWAI
The statutory standard is deliberately low. Any measurable reduction in judgment, physical control, or care while operating a vehicle qualifies. You do not need to be visibly intoxicated or weaving between lanes.1Justia. Colorado Code 42-4-1301 – Driving Under the Influence – Driving While Impaired – Driving With Excessive Alcoholic Content – Definitions – Penalties
BAC levels create presumptions that shape how a case is argued. A BAC at or below 0.05% creates a presumption that you were not impaired. Above 0.05% but below 0.08%, the law allows a “permissible inference” of impairment, which is where DWAI lives. At 0.08% or above, the inference shifts to DUI.1Justia. Colorado Code 42-4-1301 – Driving Under the Influence – Driving While Impaired – Driving With Excessive Alcoholic Content – Definitions – Penalties These are inferences, not absolute rules. A prosecutor can still pursue DWAI with a BAC below 0.05% if other evidence supports impairment, and a defendant with a BAC above 0.05% can argue they were not actually impaired.
Marijuana and Other Drugs
Colorado sets a separate threshold for marijuana. A blood test showing five nanograms or more of delta-9 THC per milliliter creates a permissible inference of driving under the influence of drugs.1Justia. Colorado Code 42-4-1301 – Driving Under the Influence – Driving While Impaired – Driving With Excessive Alcoholic Content – Definitions – Penalties For other drugs, including prescription medications and controlled substances, there is no fixed concentration threshold. Prosecutors rely on behavioral evidence and expert testimony. A driver can face DWAI charges for prescription drug impairment even when taking medication as directed, if that medication reduced their driving ability.
Criminal Penalties by Offense Number
DWAI penalties escalate sharply with each prior alcohol- or drug-related driving conviction. Prior DUI, DUI per se, DWAI, and vehicular assault involving alcohol all count. Colorado uses no lookback period, so a DWAI from decades ago still counts as a prior.
First Offense
A first DWAI is a traffic misdemeanor. It carries two to 180 days in jail, though the court can suspend the two-day minimum if you complete a court-ordered alcohol and drug evaluation and follow the recommended treatment. Fines run $200 to $500 and can also be suspended at the court’s discretion. Community service of 24 to 48 hours is mandatory with no option to suspend, and the court can impose up to two years of probation with treatment and monitoring conditions.
High-BAC cases are treated differently. If your BAC was 0.20% or higher at the time of driving, the minimum jail sentence jumps to ten days and the maximum increases to one year, even on a first offense.2Justia. Colorado Code 42-4-1307 – Penalties for Traffic Offenses Involving Alcohol and Drugs
Second Offense
A second conviction for any combination of DUI or DWAI carries ten consecutive days to one year in jail, fines of $600 to $1,500, and 48 to 120 hours of mandatory community service. The ten-day minimum is consecutive, meaning it cannot be split into weekends or staggered.3FindLaw. Colorado Code 42-4-1307 – Penalties for Traffic Offenses Involving Alcohol and Drugs Courts also require a Level II alcohol and drug education or treatment program, which runs significantly longer and costs more than the Level I program ordered for first offenses.
Third Offense
A third conviction raises the mandatory minimum to 60 consecutive days in jail, with a one-year maximum. Fines and community service stay in the second-offense range. During the 60-day mandatory period, the court cannot substitute alternatives like home detention or electronic monitoring, though limited work release or educational programs may be allowed.3FindLaw. Colorado Code 42-4-1307 – Penalties for Traffic Offenses Involving Alcohol and Drugs
Fourth or Subsequent Offense
A fourth or later DUI or DWAI is a Class 4 felony. The case moves from county court to district court, and a conviction carries two to six years in state prison, plus three years of mandatory parole. Fines also increase substantially. At this level, the practical difference between DWAI and DUI disappears: both count equally toward the felony threshold, and the felony penalties are the same either way.
License Consequences
License consequences run on a separate track from the criminal case, and the two proceedings can move at the same time.
Points and Suspension Thresholds
A DWAI conviction adds eight points to your driving record. The Colorado DMV can suspend an adult license after 12 or more points in any 12-month period, or 18 or more points within 24 months.4Justia. Colorado Code 42-2-127 – Authority to Suspend License – To Deny License – Type of Conviction – Points A single DWAI conviction alone won’t hit those thresholds, but combined with any other moving violation in the same window, you can be at risk. Drivers under 18 face a stricter threshold: more than five points in 12 months can trigger suspension.
Administrative Revocation
A first-time DWAI at a BAC between 0.05% and 0.08% does not trigger an automatic administrative license revocation. That process applies at BACs of 0.08% or higher, which would typically be a DUI. For those cases, the DMV revokes for nine months on a first violation, one year on a second, and two years on a third or subsequent.5Justia. Colorado Code 42-2-126 – Revocation of License Based on Administrative Determination So a DWAI often carries lighter immediate license consequences than a DUI, at least on a first offense.
Underage Drivers
Colorado applies a lower BAC threshold for drivers under 21. Any driver under 21 with a BAC between 0.02% and 0.05% faces an Underage Drinking and Driving (UDD) charge, separate from DWAI.6Colorado State Patrol. DUI – Don’t Underestimate Impairment A first UDD violation brings a three-month license revocation, a second brings six months, and a third results in one year.5Justia. Colorado Code 42-2-126 – Revocation of License Based on Administrative Determination If an underage driver’s BAC exceeds 0.05%, standard DWAI or DUI charges apply with the same penalties an adult would face.
Ignition Interlock
Drivers with multiple DUI or DWAI convictions must hold an interlock-restricted license for at least two years, and up to five, after reinstatement before an unrestricted license is available. The device requires you to blow into a breath sensor before the vehicle will start. An interlock-restricted license also opens a path to early reinstatement: drivers whose license has been revoked for a year or more due to a DUI or DWAI can apply for early reinstatement if they accept the interlock requirement and maintain SR-22 insurance for the longer of three years or the full interlock period.7FindLaw. Colorado Code 42-2-132.5 – Interlock-Restricted License
Habitual Traffic Offender
Three or more major traffic convictions within seven years qualifies a driver as a habitual traffic offender. Qualifying offenses include DUI, DWAI, reckless driving, driving on a suspended license, vehicular assault, and vehicular homicide.8FindLaw. Colorado Code 42-2-202 – Habitual Offenders – Frequency and Type of Violations Once designated, the DMV immediately revokes the license.9Justia. Colorado Code 42-2-203 – Authority to Revoke License of Habitual Offender Reinstatement is not automatic; it requires petitioning the DMV after the revocation ends.
Refusing a Chemical Test
Colorado’s express consent law requires anyone driving on the state’s roads to submit to chemical testing when an officer has probable cause to believe the driver committed DUI or DWAI. Drivers 21 and older can choose blood or breath testing for alcohol cases. If you decline a blood draw, officers will administer a breath test instead.10Justia. Colorado Code 42-4-1301.1 – Expressed Consent for the Taking of Blood, Breath, Urine, or Saliva Sample – Testing – Fund – Rules – Repeal When drug impairment is suspected, the officer can require blood, saliva, or urine.
Refusing any required test triggers automatic license revocation. First refusal: one year. Second: two years. Third or subsequent: three years.5Justia. Colorado Code 42-2-126 – Revocation of License Based on Administrative Determination Those periods run whether or not you are ultimately convicted. A refusal also classifies you as a “persistent drunk driver” under Colorado law, which triggers mandatory ignition interlock requirements and longer treatment programs if you later reinstate your license.
Field sobriety tests are different. They are voluntary, and refusing them carries no immediate legal penalty. Officers can still note the refusal and arrest you based on other observations like slurred speech, the smell of alcohol, or erratic driving.
Consequences That Outlast the Sentence
What the judge orders is only part of the picture. Some effects of a DWAI conviction continue long after the fine is paid and the jail time is served.
A Permanent Record
Unlike many misdemeanors, a DWAI conviction in Colorado cannot be sealed or expunged. The conviction stays on your record permanently, visible to employers, landlords, and licensing boards. That also means a DWAI from twenty years ago still counts as a prior if you are charged again. Some countries, including Canada, restrict entry for people with alcohol-related driving convictions, which can affect business and personal travel.
Employment and Commercial Driving
Employers in healthcare, transportation, government, and education often run background checks and treat alcohol-related driving offenses as disqualifying. For holders of a commercial driver’s license, federal regulations disqualify CDL holders from operating commercial vehicles after an alcohol-related driving conviction, even if the offense occurred in a personal vehicle. A first disqualification lasts one year. A second is a lifetime bar.
Insurance and SR-22
Insurance premiums typically spike after a DWAI conviction. The DMV may also require you to file an SR-22, a certificate from your insurance company confirming you carry at least the state’s minimum liability coverage. The SR-22 is not a separate policy; it is a monitoring mechanism that alerts the DMV if your coverage lapses.11Colorado Department of Revenue – Motor Vehicle. SR-22 and Insurance Information If the policy is canceled or expires while the SR-22 is active, your license faces additional suspension. For drivers with interlock-restricted licenses, the SR-22 must be maintained for at least three years or the length of the interlock restriction, whichever is longer.7FindLaw. Colorado Code 42-2-132.5 – Interlock-Restricted License
Deferred Sentencing and the Court Process
Colorado allows deferred sentencing for some DWAI cases if the defendant, defense attorney, and district attorney all agree. You plead guilty, but the court delays entering the conviction for up to two years on a misdemeanor. During that time, you comply with conditions like alcohol education, treatment, community service, and no new offenses. Complete them, and the plea is withdrawn and the charge dismissed with prejudice, opening the door to sealing the arrest record. Violate them, and the court enters the conviction and proceeds to sentencing on the original plea. Deferred sentencing is most realistic for first-time offenders without aggravating factors; prosecutors are far less likely to agree on repeat offenses, high-BAC cases, or accidents.
After a DWAI arrest, the case moves through arraignment, pretrial discovery, and either a plea agreement or trial. Discovery is often where DWAI cases turn: police reports, body camera footage, chemical test results, and calibration records for testing equipment all become available for review. A defense attorney looks for a traffic stop without reasonable suspicion, improperly administered field sobriety tests, breath-test machines out of calibration, or blood samples that sat too long before analysis. Serious problems can support motions to suppress, which often lead to reduced charges or dismissal. At trial, the prosecution must prove impairment beyond a reasonable doubt under the “slightest degree” standard.
When a Lawyer Matters
The most common mistake with a DWAI is treating it like a traffic ticket. “Ability impaired” sounds less serious than “under the influence,” and some people figure they can handle it themselves or plead guilty and move on. That calculation tends to cost more in the long run. An experienced defense attorney can identify whether the traffic stop was lawful, whether the officer followed proper testing procedures, and whether the chemical evidence actually supports the charge.
Legal representation becomes critical for a second or subsequent offense, where mandatory jail time is on the table and a felony is one conviction away. An attorney can also represent you at the DMV administrative hearing, which is a separate proceeding from the criminal case and has its own deadlines. Miss the window to request that hearing, and you lose the chance to challenge a license revocation before it takes effect.
