Winning a DMV express consent hearing (“administrative hearing”) following a Colorado DUI is actually more difficult than winning the criminal case. In DUI criminal cases, the stakes are serious – you could go to jail if convicted. Therefore, the prosecutor bears the burden of proving guilt beyond a reasonable doubt, a very high standard.
At DMV hearings – where only your driver’s license is on the line – the state has a much lower burden. Since the case is administrative and not criminal, the state just has to show that it was more likely than not (“by a preponderance of the evidence”) that you were in physical control of the vehicle:
- while impaired by alcohol/drugs or
- with an illegal BAC (blood alcohol level) level.1
Therefore, winning your criminal trial while losing your DMV administrative hearing based on the same evidence is not unusual. Although DMV hearings may be challenging to win, they are not impossible.
In this article, I discuss what you need to know about winning your DMV hearing in your DUI cases.
Best DUI Defenses
The most effective defenses to DUI allegations always turn on the specific facts of the case. Ten potential defense strategies you can use at your Colorado DMV express consent hearing include:
- The police lacked reasonable suspicion to pull you over, and/or the police lacked probable cause to arrest you for DUI.
- The police did not inform you of the “express consent” law.
- You were not the person driving the vehicle, and the police arrested the wrong person.
- You had a medical episode that mimicked intoxication. Examples include being in a diabetic coma or having a seizure.
- You had dental work such as a bridge that caused alcohol to pool, which caused the breathalyzer to return inaccurate BAC levels.
- You had a medical condition that caused falsely high breathalyzer results, such as acid reflux or GERD.
- The police officer administered the field sobriety tests incorrectly.
- The police officer did not observe you for 15 minutes prior to administering the breathalyzer, or more than two hours elapsed between the arrest and taking the breath or blood test.
- The breathalyzer was defective, it had not been calibrated recently, or the tech who last calibrated the breathalyzer let their certification lapse.
- The blood test results were contaminated or tampered with.
Depending on the case, potential evidence can include eyewitness testimony, surveillance video, breathalyzer maintenance records, and/or medical records.2 
Requesting DMV Hearings
You must request an administrative hearing in order to contest your license suspension. They are not automatic.
If you took a breath test (or refused to take any test), you must request a DMV hearing within seven days of the arrest. If you do not request a hearing, the license suspension begins after the seventh day. If you took a blood test following the DUI arrest, you may keep your driver’s license until the blood test results come back.
At that point, you have 10 days from the date the letter was sent to request a hearing. If you do not request a hearing, the license suspension will begin after the 10th day.3 It is very rare for the DMV to grant extensions, so you must request a hearing in a timely manner. See the table in the following section for how long the DMV will revoke your license if you fail to make a timely request.
If You Lose
If you lose your Colorado DMV hearing, then your license will be revoked. As the following table shows, the more DUIs you have, the longer the revocation period.4
| DUI Offense | Driver’s License Revocation by Colorado DMV |
| First offense | 9 months |
| Second offense | 1 year |
| Third or subsequent offense | 2 years |
| Chemical test refusal (refusing to take a breath or blood test following a DUI arrest) |
|
Since the DMV understands how vital driving is, you can usually reinstate your driving privileges immediately if you install an ignition interlock device (IID) in your vehicles. However, if you refused a chemical test, you have to wait two months into the revocation period before you can reinstate your license.
IIDs are breathalyzers that attach to your steering wheel and are wired through the ignition system. The device disables your vehicle if it detects alcohol on your breath.
You are also responsible for all costs associated with installing and maintaining the IID. You can appeal a lost DMV hearing, though most people choose not to since reversals are rare.
If You Win
If you win your DMV express consent hearing, your driver’s license will not be revoked. Any fines or fees assessed in relation to the case will be dismissed or refunded. Also, the DMV will remove any pending action from your driving record.
Remember that even if you win the DMV hearing, you can still get convicted of DUI in criminal court and have your license revoked after all. The DMV case and criminal case are separate, and the only way to keep your license is to win both.
Having an Attorney Represent You
Having an experienced Colorado criminal defense attorney increases the odds of winning DMV express consent hearings. In practice, administrative judges take you more seriously if you are represented by counsel. If you hire an attorney, you should expect them to:
- Request your hearing within the required time frame.
- Conduct an independent investigation of your case and compile all the relevant evidence that is favorable to your side, such as witness statements, accident records, your driving record, and certificates of completion of DUI School.
- Prepare all your defenses supported by the best facts and laws.
- Inform you of everything you need to know about the DMV process so that you feel confident you are getting the best defense.
- Arrive at the hearing on time with all the relevant documentation and be ready to cross-examine the arresting officer in your case and argue to the hearing officer why you should keep your license.
Why DMV Hearings Are Worth It
Even though DMV hearings are hard to win, you should still have them.
Firstly, the DMV hearing is a good dry run for your DUI criminal case. Even though the DMV case is far more informal than a criminal trial, the DMV hearing is a valuable setting for your defense lawyer to test certain arguments and probe the police’s testimony.
What happens at the hearing can also give your attorney material with which to impeach the state’s witnesses at trial. Plus, there is always the chance that the hearing officer will find in your favor and allow you to keep your driving privileges.
Location of Hearing
When the DMV replies to your request for a hearing, they will provide the address, date, and time to be there. Your attorney may be able to go in your place.
What the Hearing Is Like
Compared to criminal trials, DMV hearings are generally less formal. The only people present are the hearing officer, you (and/or your attorney), and the arresting officer. The hearing officer is not a real judge and probably not an attorney either.
The hearing officer will review your case’s “express consent” packet, which contains materials relevant to your case, such as the police report and any chemical test results. Depending on your case, your attorney can object to some or all of this material being admitted as evidence. Eventually, the hearing officer will swear in the arresting officer.
The officer will then recount what led up to your DUI arrest and why they believed there was probable cause that you were committing DUI. Your attorney can also cross-examine the officer. If you wish to testify on your behalf, your attorney should have prepared you beforehand about what to say and what not to say.
The hearing must comply with the Colorado Rules of Administrative Procedure (rather than the stricter Rules of Criminal Procedure). The Colorado Rules of Evidence do apply to DMV hearings, but they are also more relaxed in criminal cases. 
Why DMV Hearings Are Called “Express Consent” Hearings
If you are pulled over on suspicion of drunk driving in Colorado, you are required to give “express consent” to take a chemical breath test or blood test. If you are suspected of drugged driving (with or without alcohol), you must submit to a chemical blood test since breath tests cannot detect drugs.
Failing Chemical Test Scores
In Colorado, driving with a blood alcohol content (BAC) of .08% or higher is DUI per se. As long as your BAC is illegal, you can be convicted of driving under the influence even if you are not technically impaired.
Note that the BAC threshold is only .04% if you are a commercial driver. Meanwhile, if you are under 21, you face underage drinking and driving (UDD) charges for driving with a BAC of only .02%.
Also note that driving with a BAC above .05% but below .08% is the lesser crime of DWAI (driving while ability impaired). 
Reasons for DMV Hearings
DMV hearings are not just for DUI cases. You are entitled to a hearing anytime you are at risk of having your license
- suspended,
- revoked,
- canceled, or
- denied by the Colorado DMV.
This typically happens if you:
- accumulate too many points on your license or
- develop a medical condition that inhibits your driving.
As with DUIs, it is important to hire an attorney to represent you in any DMV cases where your license is at issue.
Criminal Penalties
If you are convicted of DUI in Colorado, you face criminal punishments even if you win the DMV case. The following table spells out these penalties.
| DUI Offense | Colorado Criminal Sentence |
| First-time DUI or DUI per se | Misdemeanor:
|
| Second-time DUI or DUI per se | Misdemeanor:
|
| Third-time DUI or DUI per se | Misdemeanor:
|
| Fourth or subsequent DUI or DUI per se | Class 4 Felony:

Frequently Asked Questions
What issues does the hearing officer decide at a Colorado DMV express consent hearing?
A Colorado DMV hearing officer generally decides whether you drove a vehicle with a blood or breath alcohol concentration of at least 0.08% at the time of driving or within two hours afterward, or whether you refused to take, choose, or cooperate with a required chemical test. Depending on the case, the hearing may also address whether the officer had reasonable grounds to believe you drove under the influence or while impaired, whether you were properly advised under Colorado’s express consent law, and whether the initial police contact and arrest were lawful.
In my experience, narrowing the case to the exact findings the hearing officer must make is critical. I do not approach a DMV hearing as a general debate about whether my client seemed intoxicated. I identify each required element and look for missing, inconsistent, or unreliable evidence that prevents the DMV from proving it.
Can I challenge an unlawful traffic stop at a Colorado DMV hearing?
Yes. Colorado law permits a driver to challenge the legality of the law enforcement officer’s initial contact and the subsequent DUI arrest during an administrative license-revocation proceeding. This can include an argument that the officer lacked reasonable suspicion for the traffic stop or lacked probable cause for the arrest.
In cases I handle, the legality of the stop can be one of the most important issues. Dash-camera footage, body-camera footage, dispatch records, and the officer’s own report sometimes tell different stories about why the vehicle was stopped. I compare those materials carefully rather than assuming the officer’s written conclusion is enough.
Should I subpoena the arresting officer to my Colorado DMV hearing?
It often makes sense to subpoena the arresting officer when the defense needs live testimony or cross-examination, but the correct strategy depends on the case. A subpoena for a law enforcement officer must generally be approved and personally served at least five calendar days before the hearing. Subpoenas for most other witnesses must be served at least 48 hours beforehand.
In my experience, subpoenaing the officer is not an automatic decision. Live testimony can expose contradictions, missing observations, testing errors, or weaknesses in the refusal allegation. On the other hand, calling the officer may give the DMV an opportunity to repair omissions in the paperwork. I evaluate what the written packet proves before deciding whether the officer’s presence is likely to help or hurt.
Will I automatically win if the police officer does not appear at the DMV hearing?
No. An officer’s absence does not necessarily result in an automatic victory because the hearing officer may consider the express consent packet and other admissible documentary evidence submitted by the DMV. The significance of the officer’s absence depends partly on whether the officer was properly subpoenaed and whether the existing documents establish every required element. The hearing officer reviews the DMV packet along with any evidence and testimony offered by the driver.
What I often see is that an officer’s absence matters most when live testimony is needed to fill an important gap or resolve a factual dispute. I look for statements that are ambiguous, internally inconsistent, unsigned, incomplete, or unsupported. If the paperwork already establishes the DMV’s case, the officer’s absence alone may not be enough.
What documents should I review before a Colorado DMV hearing?
You should review the complete express consent packet, which may include the officer’s affidavit, police reports, chemical-test results, advisement documents, and other materials submitted to the DMV. Once a hearing request is granted and the DMV receives the documents from law enforcement, the DMV generally mails a copy to the driver. A driver may also request an additional copy using the DMV’s document-request procedure.
In my experience, small paperwork details can become major hearing issues. I check dates, times, signatures, BAC collection times, advisement language, descriptions of the alleged refusal, and whether the report establishes who was driving. I also compare the packet with videos, dispatch records, medical evidence, and witness accounts whenever those materials are available.
Can I introduce my own evidence at a Colorado DMV hearing?
Yes. A driver may present relevant evidence and testimony at the hearing, and may question opposing witnesses. Potential defense evidence can include body-camera or dash-camera footage, medical records, photographs, witness testimony, test-maintenance records, proof of environmental or medical interference, and evidence contradicting the officer’s account. The hearing officer considers this evidence together with the express consent packet.
I tell clients that simply attending and denying the allegation is rarely the strongest approach. Whenever possible, I try to support the defense with objective evidence. A timestamp, video recording, hospital record, or independent witness can be more persuasive than competing recollections of a stressful roadside encounter.
Should I testify at my Colorado DMV hearing?
You have the opportunity to testify, but you are not always required to do so. Testimony may help explain a medical condition, a testing problem, what the officer said, whether you actually refused testing, or whether someone else was driving. However, the testimony is given under oath, may be questioned by the hearing officer, and can create statements that affect the related criminal DUI case.
In my experience, the decision to testify should be made only after reviewing the police reports and other evidence. Testimony can be very useful when the driver possesses facts no other witness can establish. It can also be risky when the prosecution may later use an inconsistent or poorly phrased answer. I prepare clients carefully and weigh the licensing benefit against the possible criminal-case consequences.
Can a Colorado DMV hearing be rescheduled?
A DMV hearing may sometimes be rescheduled for just cause, such as a medical problem, law enforcement emergency, or conflict with another court or administrative hearing. The Hearings Division must be notified before the case is dismissed, and Colorado treats some scheduling requirements as jurisdictional rather than optional.
What I have seen is that drivers should never assume a continuance will be granted merely because the scheduled date is inconvenient. Requests should be made promptly, supported with a specific reason, and handled through the correct procedure. Missing the hearing without obtaining approval can result in the revocation being sustained without the driver presenting a defense.
Can I keep driving while waiting for my Colorado DMV hearing?
A timely hearing request can generally preserve temporary driving privileges while the administrative case is pending, depending on the type of notice and the circumstances of the chemical test. The DMV provides an opportunity to request a hearing before the license restriction takes effect, but the request must be made within the applicable deadline.
I regularly warn clients that requesting a hearing and obtaining valid temporary driving authority are procedural matters that must be handled correctly. A person should not assume that a hearing request, a copy of an email, or an upcoming hearing date automatically authorizes driving. I verify the client’s license status and temporary permit rather than risking a separate charge for driving under restraint.
What happens if I lose my Colorado DMV hearing?
If the hearing officer sustains the revocation, the DMV will impose the applicable loss of driving privileges. A driver may seek judicial review in Colorado district court, but the court generally reviews whether the agency exceeded its authority, misapplied the law, followed the required procedure, or entered a decision unsupported by the administrative record. An appeal is not ordinarily a completely new hearing with new evidence.
In my experience, the best opportunity to create a favorable record is at the DMV hearing itself. Evidence, objections, and legal issues that are not properly raised may be difficult to introduce later. That is why I treat the administrative hearing as a genuine evidentiary proceeding rather than merely a preliminary step in the DUI case.
How long do I have to appeal an adverse Colorado DMV decision?
A petition for judicial review generally must be filed within 35 days after the DMV’s final agency action. This deadline is strict, and filing an appeal does not necessarily stop the license revocation automatically. The driver may need to request a stay while the district court reviews the administrative decision.
I tell clients to discuss an appeal immediately after an unfavorable ruling. A successful appeal usually requires an identifiable legal, procedural, or evidentiary error—not simply disagreement with the hearing officer’s credibility findings. Prompt review of the recording, exhibits, and written order helps determine whether there is a viable basis for judicial review.
How long do I have to request a DMV hearing in Colorado?
If you took a breath test or refused chemical testing, you have exactly seven days from the date of your arrest to request a hearing. If you took a blood test, you can keep your license until the results come back, at which point you will be mailed a letter and given a strict deadline (usually 10 days from the mailing date) to request your hearing. If you miss the deadline, your license will be automatically suspended.
In my experience, missing the hearing deadline is one of the most preventable mistakes people make after a DUI arrest. Many drivers understandably focus on the criminal case and do not realize the DMV has its own separate deadlines. I encourage clients to request the hearing immediately so they preserve every available option and give their attorney time to prepare the strongest possible defense.
Is the DMV hearing the same as my criminal court date?
No. The DMV Express Consent hearing is a civil administrative process that only deals with your driving privileges. Your criminal court case is entirely separate and handles potential jail time, fines, and criminal convictions. It is possible to win your criminal case but still lose your driver’s license at the DMV hearing.
What I have seen is that many clients are surprised to learn they are essentially fighting two different battles at once. I often use the DMV hearing not only to protect a client’s driving privileges but also to gather testimony, identify weaknesses in the state’s evidence, and obtain information that can be valuable later in the criminal DUI case.
What happens to my license if I refused the breath or blood test?
Refusing a chemical test carries stricter administrative penalties. A first-time refusal results in an automatic one-year license revocation, compared to a nine-month revocation if you took the test and failed. You also have to wait two months into the revocation period before you are eligible to reinstate your license with an Ignition Interlock Device (IID).
In my experience, many people refuse testing because they believe it will improve their chances of beating the DUI charge. Unfortunately, I have seen that the refusal itself often creates significant DMV consequences. Every refusal case is different, though, and I carefully examine whether the officer properly advised the driver under Colorado’s Express Consent law and whether the alleged refusal was legally valid.
Can I still drive if I lose my DMV hearing?
If your license is revoked, you may not drive normally. However, in most cases, you can reinstate your driving privileges early by installing an Ignition Interlock Device (IID) in your vehicle and carrying SR-22 insurance.
I know that losing the ability to drive can jeopardize a person’s job, education, and family responsibilities. One of the first things I discuss with clients after an adverse DMV ruling is whether they qualify for early reinstatement with an IID and what steps they need to take to get back on the road as quickly as the law allows.
Do I really need a lawyer for a DMV hearing?
While you are not legally required to have an attorney, it is highly recommended. The state only needs a “preponderance of the evidence” (51% likelihood) to suspend your license, making DMV hearings surprisingly difficult to win. An experienced attorney can object to evidence, cross-examine the arresting officer, and use the hearing to build a stronger defense for your upcoming criminal trial.
In my experience, people often underestimate how technical DMV hearings can be. Success frequently turns on procedural rules, evidentiary objections, inconsistencies in the officer’s testimony, or defects in the DMV paperwork that are easy to overlook without substantial experience.
Even when preserving the license is difficult, a well-handled hearing can provide valuable testimony and evidence that strengthens the defense in the criminal case.
