Being arrested for DUI in Colorado is overwhelming. One moment you’re pulled over, and the next you’re facing criminal charges, possible jail time, and the loss of your driver’s license. For many people, the most stressful part is not knowing what comes next.

Our DUI attorney will walk you through exactly what happens after a DUI arrest in Colorado, from the roadside stop to court appearances, DMV hearings, and potential case outcomes. Understanding the timeline can help you avoid costly mistakes—and protect your future.

Step 1: The Traffic Stop and Initial Investigation

Most DUI cases begin with a traffic stop. Law enforcement must have reasonable suspicion to pull you over, such as:

  • Swerving or drifting between lanes

  • Speeding or driving too slowly

  • Broken taillights or equipment violations

  • Reports of erratic driving

Once stopped, the officer looks for signs of impairment, including slurred speech, bloodshot eyes, odor of alcohol, or difficulty following instructions.

At this stage, the officer may ask you to perform roadside sobriety tests. In Colorado, these tests are voluntary, not mandatory. However, refusing them does not prevent arrest.

Important: What you say and do during this phase often becomes evidence later.

Step 2: Arrest and Chemical Testing (Express Consent Law)

If the officer believes there is probable cause, you will be arrested for DUI or DWAI and taken into custody.

Under Colorado’s Express Consent Law, drivers are required to submit to a chemical breath or blood test after a lawful DUI arrest.

What Happens If You:

  • Take the test:
    • A BAC of 0.08% or higher typically results in DUI charges
    • A BAC between 0.05% and 0.079% may result in DWAI charges
  • Refuse the test:
    • Automatic DMV license revocation
    • Refusal can be used against you in court

Blood tests are often sent to the Colorado Bureau of Investigation (CBI), and results may take weeks to return.

Step 3: Booking, Bond, and Release

After testing, you are taken to jail for booking. This includes fingerprints, photographs, and paperwork.

Depending on the circumstances, you may:

Your release paperwork will usually include:

  • A court date

  • Temporary driving paperwork

  • Conditions of release (such as no alcohol consumption)

Step 4: DMV License Revocation Starts Immediately

This is where many people get caught off guard.

Your criminal DUI case and your DMV case are separate. Even if your criminal case is dismissed, you can still lose your license through the DMV.

After a DUI arrest:

  • You typically have 7 days to request a DMV Express Consent hearing

  • If you do nothing, your license is automatically revoked

Typical Revocation Periods:

  • First DUI: up to 9 months

  • Refusal: 1 year or longer

  • Prior offenses: longer revocation periods

A knowledgeable DUI attorney can handle the DMV hearing and explore early reinstatement options.

Step 5: First Court Appearance (Advisement)

Your first court date is often called an advisement hearing. This usually occurs within a few weeks of your arrest.

At this hearing:

  • The judge explains the charges and penalties

  • You are advised of your rights

  • Bond conditions are reviewed

  • A future court date is scheduled

You are not required to plead guilty at this stage, and doing so prematurely can seriously harm your case.

Step 6: Pretrial Phase and Evidence Review

This is where DUI cases are often won or lost.

Your attorney will:

  • Review police reports and body-cam footage

  • Analyze breath or blood test procedures

  • Examine traffic stop legality

  • Look for constitutional violations

Common defense issues include:

  • Improper traffic stop

  • Faulty breath testing equipment

  • Blood draw errors or contamination

  • Inaccurate police observations

Many DUI cases are resolved during this phase through dismissals, reductions, or favorable plea negotiations.

Step 7: Motions Hearings and Negotiations

If legal issues are identified, your attorney may file motions to suppress evidence or challenge the legality of the arrest or testing.

Simultaneously, negotiations with the prosecutor may occur. Depending on the facts, charges may be:

Every case is different, and outcomes depend heavily on the strength of the evidence.

Step 8: Trial (If Necessary)

If no acceptable resolution is reached, your case may proceed to trial.

At trial:

  • The prosecution must prove guilt beyond a reasonable doubt

  • Evidence and witness testimony are challenged

  • Expert witnesses may testify about testing flaws

Many DUI cases never reach trial, but preparation for trial strengthens negotiation leverage.

Step 9: Sentencing (If Convicted)

If you plead guilty or are found guilty, the court will impose sentencing and penalties.

Possible DUI Penalties Include:

  • Jail time or home detention

  • Fines and court costs

  • Alcohol education and therapy

  • Community service

  • Probation

  • Ignition interlock device

Penalties increase with:

  • Prior DUI convictions

  • High BAC levels

  • Accidents or injuries

  • Child passengers in the vehicle

Step 10: Life After a DUI Case

A DUI conviction can impact:

  • Your criminal record

  • Employment opportunities

  • Professional licenses

  • Insurance rates

  • Driving privileges

This is why early legal intervention is so critical.

Why Hiring a Colorado DUI Attorney Early Matters

An experienced Colorado DUI defense attorney can:

  • Protect your license

  • Challenge evidence

  • Negotiate reduced charges

  • Fight for dismissal when possible

  • Guide you through every step of the process

Frequently Asked Questions About DUI Arrests in Colorado

How long does a DUI case take in Colorado?

A DUI case in Colorado can take several weeks to several months, depending on the complexity of the case, whether motions are filed, and whether the case goes to trial. Cases involving blood tests often take longer because lab results can take weeks to return.

Will I lose my license immediately after a DUI arrest?

Not immediately—but the process starts right away. After a DUI arrest, you generally have 7 days to request a DMV Express Consent hearing. If you miss this deadline, your license will be automatically revoked, even if your criminal case is still pending.

Is the DMV case separate from the criminal DUI case?

Yes. The DMV license revocation case is completely separate from the criminal court case. You can win one and lose the other. This is a common source of confusion for DUI defendants in Colorado.

What happens if I refuse a breath or blood test in Colorado?

Refusing a chemical test triggers automatic license revocation under Colorado’s Express Consent Law. A refusal can also be used as evidence against you in court and often results in longer license suspensions than failing a test.

Do I have to go to jail for a first DUI in Colorado?

Not necessarily. While jail is a possible penalty for a first DUI, many first-time offenders avoid jail through probation, treatment programs, or alternative sentencing—especially when represented by an experienced DUI attorney.

Can a DUI charge be reduced or dismissed in Colorado?

Yes. Depending on the evidence, a DUI charge may be reduced to DWAI or reckless driving, or dismissed entirely. Issues such as illegal traffic stops, faulty breath tests, or improper police procedures can significantly weaken the prosecution’s case.

Should I plead guilty at my first court appearance?

In most cases, no. The first court date (advisement) is not the time to plead guilty. Important evidence may not yet be available, and pleading too early can eliminate defense options. Speaking with a DUI attorney before entering any plea is strongly recommended.

How soon should I contact a DUI attorney after an arrest?

Immediately. Early legal representation can help protect your driver’s license, preserve evidence, handle DMV deadlines, and position your case for the best possible outcome. The first few days after a DUI arrest are often the most critical.
