Denver DUI Per Se Lawyer
Colorado law draws a clear line: if a chemical test shows your blood alcohol concentration at 0.08 or above, you can be convicted of driving under the influence regardless of how you appeared, how you drove, or what any officer observed. That line is what DUI per se means in practice, and it is why many people find themselves charged even when they felt perfectly capable of driving. The per se framework removes the subjective question of impairment from the equation and replaces it with a number. That shift changes how a defense is built, what evidence matters, and where the real legal fights happen.
Denver law enforcement takes impaired driving enforcement seriously, particularly along corridors like Colfax Avenue, I-25 through downtown, I-70 heading toward the mountains, and in entertainment districts like LoDo and RiNo where late-night patrols actively look for impaired drivers after games, concerts, and bar closings. When a breath or blood result at or above the legal limit produces a per se charge, the prosecution’s case looks simple on paper. It rarely is, because the path between a roadside stop and a valid chemical result involves many steps, each governed by specific legal requirements that, when not followed correctly, can undermine the result entirely.
A DUI per se charge in Denver triggers two separate proceedings: a criminal case in Denver County District Court and a DMV Express Consent hearing that determines whether your license will be revoked. Both have their own timelines and their own consequences. Missing either one, or treating them as less urgent than they are, can cost you your license before your criminal case is ever resolved. An attorney who understands how both processes work, and how to fight on both fronts simultaneously, is what this specific charge actually requires.
What Per Se Actually Means and Why It Changes the Defense
A standard DUI charge in Colorado rests on proving that a driver was substantially incapable of safely operating a vehicle due to alcohol or drugs. That question involves field sobriety tests, officer observations, driving behavior, and other indicators of impairment. Per se is a different animal entirely. Under Colorado’s DUI per se statute, the chemical test result itself is the offense. If the prosecution can establish that your BAC was 0.08 or higher at the time of driving, the impairment question is legally irrelevant. You can walk a straight line flawlessly and the per se charge still stands if the number says otherwise.
This structure means the defense pivots toward the chemical test itself. Was the breath testing device properly calibrated and maintained? Was the blood draw conducted in a medically acceptable manner? Was the sample stored and handled correctly through the chain of custody? Was the test administered within the legally required timeframe? Did the arresting officer properly advise you of your Express Consent rights before requesting the test? Each of these questions is a potential avenue for challenging the reliability or admissibility of the test result that forms the backbone of the per se case. Without that result, the per se charge collapses.
Colorado law also recognizes a separate DWAI tier, with a BAC at or above 0.05 but below 0.08. That charge, driving while ability impaired, carries its own penalties but is distinct from DUI per se. Understanding exactly which charge or combination of charges has been filed, and whether the BAC reading genuinely supports each one, is the first step in knowing what you are actually up against.
Why Reid DeChant Is the Right Attorney for a Denver DUI Per Se Case
When the prosecution’s case rests on a chemical test result, you need a defense attorney who understands not just criminal law but the specific science, procedures, and regulatory requirements that govern how that result was obtained. Reid DeChant has spent his career building exactly that kind of practice. As a former public defender who handled high-volume criminal caseloads across Denver, Adams County, and Broomfield, Reid has cross-examined police officers over breath test administration, challenged blood draw procedures, and litigated Express Consent advisement issues in courts throughout the metro area.
The case results on DeChant Law’s record speak directly to this type of work. Multiple DMV Express Consent actions have been dismissed due to improper Express Consent advisements, failures to administer chemical tests within the required two-hour window, and other procedural deficiencies in how officers handled the testing process. A DUI and careless driving case resulted in a not guilty verdict at trial. A DUI out of Jefferson County was dismissed. A DUI out of Douglas County was dismissed. A DUI third offense out of Douglas County resulted in a not guilty verdict. These are not soft cases where the evidence was weak from the start. These are wins in the specific types of proceedings that follow a DUI per se arrest in Colorado.
Reid’s training at the Trial Lawyers College, the program founded by legendary trial attorney Gerry Spence, has shaped an approach to defense that goes beyond reciting legal arguments. He is a member of the National Association of Criminal Defense Lawyers and the Colorado Criminal Defense Bar, which keeps him connected to the latest developments in DUI science, testing challenges, and emerging defense strategies. For someone facing a per se charge where the number appears to speak for itself, that combination of trial record, procedural knowledge, and membership in the communities where defense strategy is developed is what actually matters.
The Colorado DUI Per Se Charges and Consequences You Need to Understand
- First-offense DUI per se: A first DUI per se conviction in Colorado carries mandatory jail time, fines, license revocation, alcohol education requirements, and potentially an ignition interlock device on your vehicle. The criminal record consequence is permanent unless addressed through post-conviction proceedings.
- Second and subsequent DUI per se offenses: Colorado significantly increases penalties for repeat offenders, with longer mandatory jail sentences, extended license revocations, and the possibility of felony classification for a third or subsequent offense under certain circumstances. The 2017 felony DUI law means prior convictions follow you differently than they once did.
- DMV Express Consent revocation: Colorado’s Express Consent law requires drivers to submit to chemical testing when lawfully arrested for DUI. A BAC at or above 0.08 triggers an automatic license revocation action that is separate from any criminal conviction. A hearing must be requested within seven days of the arrest to contest this action, a deadline that does not pause while you sort out the criminal side of the case.
- BAC between 0.08 and 0.149: In this range, first-offense DUI per se carries a specific statutory penalty framework. While still serious, these cases sometimes present more flexibility in negotiated outcomes depending on the strength of the evidence and the defendant’s driving and criminal record.
- BAC at 0.15 or above (aggravated range): Colorado treats a BAC of 0.15 or higher as a factor that triggers enhanced penalties and mandatory ignition interlock requirements. Prosecutors and judges treat these cases differently, and the defense strategy may need to account for that heightened posture.
- Commercial driver DUI per se: For holders of commercial driver’s licenses, the per se limit drops to 0.04 when operating a commercial vehicle. A DUI per se finding can trigger federal CDL disqualification independent of Colorado state penalties, with consequences that can end a professional driving career.
- Drug-based DUI per se: Colorado law establishes a THC per se limit of five nanograms per milliliter in blood for cannabis impairment, though this is treated somewhat differently than the BAC framework. For drugs other than cannabis and alcohol, per se standards apply at detectable amounts for certain scheduled substances.
After a DUI Per Se Arrest in Denver: What Needs to Happen and When
The seven-day deadline for requesting a DMV Express Consent hearing is the most urgent timeline following a DUI per se arrest in Denver. This request must be made to the Colorado Division of Motor Vehicles, and if it is missed, the license revocation proceeds automatically without any opportunity to contest it. Many people are not told about this deadline at the time of arrest, or they assume their criminal defense attorney will handle it without specifically confirming that task. Your attorney should confirm immediately that the hearing request has been submitted and that you have not already forfeited your opportunity to contest the revocation.
On the criminal side, your first appearance in Denver County will be an arraignment at the Lindsey-Flanigan Courthouse, located at 520 West Colfax Avenue. This is where charges are formally read and an initial plea is entered. The arraignment is not where the real defense work happens, but it is where conditions of release are set and where having an attorney already in place matters. If you are released from custody, do not assume the urgency decreases. Your attorney will need to begin gathering police reports, breath test calibration records, blood draw documentation, chain of custody logs, and dashcam or bodycam footage as soon as possible, because law enforcement agencies have their own retention schedules that do not wait indefinitely.
Avoid discussing the specifics of your arrest with anyone other than your attorney. This includes social media, which has become a meaningful source of evidence for prosecutors in DUI cases, and it includes conversations with other people involved in the incident. The instinct to explain what happened is natural, but those explanations can create problems when they conflict with what the evidence later shows or with the specific legal arguments your attorney needs to make.
If your license is revoked pending the DMV hearing outcome, look into whether you qualify for a restricted license or whether an ignition interlock device would allow you to continue driving during the proceeding. The Colorado DMV has provisions for this in some circumstances, and a Denver DUI per se attorney can advise you on whether you qualify while the case is pending.
Questions About DUI Per Se in Colorado and Denver
What exactly is DUI per se, and how is it different from a regular DUI charge?
A standard DUI requires proving you were substantially incapable of safely driving due to alcohol or drugs. DUI per se means your BAC was at or above 0.08 at the time of driving, and that fact alone supports the charge regardless of how you appeared or behaved. Both charges can be filed together based on the same arrest, which is common in Colorado cases where a breath or blood result is obtained.
Can I fight a DUI per se charge if the breathalyzer showed 0.08 or higher?
Yes. The chemical test result has to be obtained correctly to be used against you. Defense challenges include whether the testing device was properly calibrated and certified, whether the officer followed the required observation period before administering the test, whether the Express Consent advisement was properly given, whether the test was administered within two hours of driving, and whether the blood sample was handled through a proper chain of custody. Any of these failures can support a motion to suppress the result, and without the result, the per se charge cannot stand.
What happens to my driver’s license after a DUI per se arrest in Colorado?
The Colorado Division of Motor Vehicles initiates a separate Express Consent revocation proceeding based on the chemical test result. You have seven days from the date of arrest to request a hearing to contest this revocation. If you do not request the hearing in time, your license will be revoked automatically. The DMV proceeding is entirely separate from your criminal case, and you can win or lose in one proceeding without that determining the outcome in the other.
What are the penalties for a first DUI per se conviction in Colorado?
A first offense generally carries mandatory minimum jail time, significant fines and surcharges, a license revocation period, required alcohol education or treatment, community service, and probation. If your BAC was 0.15 or above, enhanced penalties apply including mandatory use of an ignition interlock device on any vehicle you drive. The exact terms depend on the specific facts of your case and how it resolves, whether through a plea, dismissal, or trial.
Is the two-hour rule for chemical testing a real defense in Colorado?
Yes. Colorado law requires that the chemical test be administered within two hours of the time of driving. If the test was taken outside that window, it may not be usable to support the per se charge. The actual enforcement and outcome of this argument depend on the specific timeline of events in your case, which is why securing dashcam footage, police report timestamps, and other documentation early in the process is critical.
Will a DUI per se conviction affect my professional license in Colorado?
It can, depending on your profession and the licensing board that governs it. Healthcare professionals, attorneys, teachers, commercial drivers, and those holding security clearances may face separate professional licensing consequences from a DUI per se conviction independent of the criminal penalties. Some boards require self-reporting within a specific timeframe after conviction. If you hold a professional license, this is a conversation to have with your defense attorney early, because the professional licensing implications may affect how the criminal case is resolved.
Can a DUI per se charge be reduced to DWAI in Denver?
Reduction to DWAI (driving while ability impaired) is a negotiated outcome that sometimes occurs when the evidence supports it or when the prosecution has weaknesses in its case. A DWAI is a lesser charge with lower penalties, though it still carries a criminal conviction and DMV consequences. Whether a reduction is available in your case depends on your BAC level, your driving history, the strength of the suppression issues, and the discretion of the Denver County DA’s office. This is a case-by-case analysis, not a standard outcome.
How long does a DUI per se case typically take to resolve in Denver courts?
Simple cases with straightforward evidence sometimes resolve relatively quickly, but cases involving suppression motions, scientific challenges to the testing equipment, or trial tend to take significantly longer. Denver County courts handle a high volume of cases, and scheduling for hearings and trials can add months to a case that goes further into the litigation process. Expect the process to take several months at minimum, and potentially over a year if the case proceeds to trial.
What happens if I refused the chemical test after being arrested for DUI in Colorado?
Refusing the chemical test after a lawful DUI arrest in Colorado triggers its own consequences under the Express Consent law, including a longer license revocation period than a test failure in some circumstances. Refusal also does not guarantee that no chemical evidence exists, because blood draws can sometimes be obtained by warrant. The strategic question of what the refusal means for your criminal defense is separate from the DMV consequences, and both need to be addressed.
Does the DUI per se BAC limit change if I am under 21 in Colorado?
Yes. Colorado applies a stricter standard for drivers under 21. Any detectable BAC at or above 0.02 can trigger a UDD (underage drinking and driving) charge, while the standard DUI per se threshold of 0.08 still applies if the higher result is reached. This dual-framework means younger drivers face a much lower bar for per se exposure and also face additional administrative license consequences through the DMV.
