Aggressive DUI Enforcement Planned in Colorado

Colorado law enforcement agencies run coordinated DUI enforcement periods throughout the year, and stepping up patrols, sobriety checkpoints, and saturation enforcement around holidays and other high-traffic weekends can significantly increase the odds that an impaired driver is stopped and arrested. A DUI or DWAI arrest during one of these periods can lead to criminal charges, a separate administrative license process through the Colorado DMV, fines, and potential jail time, even for a first offense.

At Shazam Kianpour & Associates, P.C., we represent clients across the Denver area who are arrested during these enforcement pushes, and our DUI and DWAI defense team follows how these campaigns are staffed and structured each year so we understand exactly what a client is up against when a stop happens during a high-enforcement weekend. We defend both alcohol-related charges and cases involving drunk driving allegations tied specifically to these seasonal patrols.

What Colorado’s Seasonal DUI Enforcement Campaigns Involve

The Colorado Department of Transportation runs a statewide initiative known as The Heat Is On, which coordinates high-visibility impaired-driving enforcement periods around holidays and major public events throughout the year. These periods can include sobriety checkpoints, saturation patrols, and additional officers assigned specifically to look for signs of impairment, and they are typically publicized in advance to encourage drivers to plan ahead.

The Heat Is On campaign runs multiple enforcement periods across the calendar year, generally timed around events such as New Year’s Eve, St. Patrick’s Day, spring break, the Fourth of July, and Labor Day weekend, along with other high-travel stretches of the summer. Local police departments and the Colorado State Patrol coordinate staffing during these windows, which can mean more marked and unmarked patrol vehicles, more sobriety checkpoints, and officers specifically assigned to watch for signs of impaired driving rather than responding to other calls.

These enforcement periods are typically announced ahead of time through CDOT’s public safety channels, partly as a deterrent and partly to encourage drivers to arrange a sober ride in advance. Even with advance notice, arrests during these windows remain common, which means understanding your rights during a stop matters just as much during a heavily publicized enforcement period as it does at any other time of year.

Recent Enforcement Numbers in Colorado

According to CDOT, Colorado averaged more than 1,300 DUI arrests per month through much of 2025, putting the state on track to surpass 16,000 total DUI arrests for the year. CDOT has also reported that impaired-driving citations tend to spike overnight, particularly between 10 p.m. and 2 a.m., which is the window when many of these targeted enforcement periods concentrate their resources. These numbers reflect how consistently impaired driving enforcement remains a priority for Colorado law enforcement, not just around a single weekend.

Blood Alcohol Content Limits and DUI Versus DWAI in Colorado

Colorado uses a blood alcohol content, or BAC, of 0.08 percent as the per se limit for driving under the influence, meaning a driver at or above that level can be charged with DUI regardless of whether they appear impaired. A driver with a BAC between 0.05 and 0.079 percent can instead be charged with Driving While Ability Impaired, commonly called DWAI, which applies when an officer believes alcohol or drugs have affected a person’s ability to drive safely, even at a lower BAC level. Even a BAC below 0.05 percent does not automatically rule out a DWAI charge, since Colorado law also allows an officer to rely on observed driving behavior and performance on field sobriety exercises.

Drivers under 21 are subject to a separate zero-tolerance standard. A driver younger than 21 with a BAC between 0.02 and 0.05 percent can be charged with Underage Drinking and Driving, which carries its own penalty structure and can affect college enrollment or job opportunities down the road. A driver with a BAC of 0.17 percent or higher can face aggravated DUI charges, which carry increased penalties compared to a standard DUI.

Marijuana and Drug-Related DUI Charges

Colorado also enforces a legal limit for marijuana impairment, set at five nanograms of active THC per milliliter of blood, and driving above that threshold can result in DUI charges that carry consequences similar to an alcohol-related DUI, including potential jail time, fines, and license suspension. Because THC affects people differently than alcohol and can remain detectable in blood for varying periods, these cases often involve additional questions about how impairment was actually measured and interpreted at the time of the stop. A driver can also face DUI charges based on a combination of alcohol and drugs, even when neither substance alone would have reached the relevant legal threshold, which adds another layer of complexity to how these cases are investigated and defended.

Penalties for a First-Time DUI or DWAI Conviction

A first offense for DUI or DWAI is charged as a misdemeanor in Colorado, but the potential consequences are still substantial. Depending on the specific charge and the facts of the case, a conviction can potentially involve:

• Jail exposure ranging from a few days up to one year, depending on the offense and any aggravating factors
• Fines and court costs that can reach into the thousands of dollars once fees and required programs are included
• License suspension and, in many cases, a mandatory ignition interlock device requirement to regain driving privileges

Beyond the direct penalties, a conviction can also affect insurance rates, employment that requires driving or a security clearance, and, for repeat offenses, whether future charges are treated as felonies. Our first-time DUI defense attorneys walk new clients through exactly what these penalties can look like for their specific charge before any decisions are made about how to proceed.

Alcohol Education and Ignition Interlock Requirements

Drivers convicted of DUI or DWAI in Colorado are generally required to complete an alcohol and drug evaluation and, depending on the results, an alcohol education or therapy program before their driving privileges can be fully restored. Many convictions also require an ignition interlock device, a breath-testing unit wired into the vehicle that the driver must use before the car will start. Drivers are typically responsible for the installation and ongoing monthly cost of the device for as long as it remains required.

Penalties for a Second or Subsequent DUI Conviction, Including Felony DUI

A second DUI or DWAI conviction generally carries harsher penalties than a first offense, including a longer potential jail term, higher fines, and an extended license revocation period that can require applying for a restricted license. A third conviction increases these consequences further and can result in an indefinite license revocation, with reinstatement typically requiring a formal application process through the Colorado DMV after a set waiting period.

For both second and third offenses, courts can also require an extended ignition interlock period, often measured in years rather than months, along with continued alcohol education requirements. The specific fines, jail exposure, and interlock length in any individual case depend on the facts, any aggravating circumstances, and how the case is ultimately resolved.

When a DUI Becomes a Felony

A fourth or subsequent DUI or DWAI offense is generally charged as a felony under Colorado law, which carries the possibility of a multi-year prison sentence rather than time in county jail. This shift from misdemeanor to felony treatment reflects how seriously Colorado law treats repeat impaired driving offenses, and it makes an early, thorough defense review especially important for anyone facing a third or later charge. Prior convictions from other states can sometimes count toward this total, depending on how the underlying offense compares to Colorado’s DUI and DWAI statutes, which adds another layer of analysis for drivers who have moved to Colorado or who were previously convicted elsewhere.

The Administrative License Process and DMV Hearings

A DUI or DWAI arrest in Colorado sets two separate processes into motion. According to the Colorado Department of Revenue’s Division of Motor Vehicles, the administrative process and the court process operate independently of one another, on separate timelines, and a result in one process does not automatically decide the other. The administrative process addresses your driving privileges directly, while the court process addresses the criminal charge itself.

You generally have a limited window after an arrest to request a DMV hearing before license restrictions take effect, and missing that window can mean losing the chance to challenge the administrative suspension separately from your criminal case. Because the two processes do not always move at the same pace, coordinating a strategy across both from the outset can make a meaningful difference in how the overall situation resolves.

Requesting a Hearing Through the Colorado DMV

Hearing requests are generally submitted through the Colorado DMV’s online driver services portal, and the request needs to identify the specific hearing officer and arresting officer involved in your case. Because the request window is short and the paperwork requirements are specific, drivers who wait to address the administrative side of their case often lose the opportunity entirely, even if their criminal case is still in its early stages.

Colorado’s Express Consent Law and Chemical Test Refusal

Under Colorado’s Express Consent Law, driving on Colorado roads means a driver has already agreed to submit to a chemical test for alcohol or drugs if a law enforcement officer has reasonable grounds to request one following a DUI arrest. Refusing a requested test carries its own administrative consequences, separate from the underlying DUI charge, and can result in a mandatory ignition interlock device requirement regardless of whether the criminal case results in a conviction.

Colorado has reported an increase in drivers refusing chemical testing in recent years, which is one reason state agencies continue to publicize the consequences of refusal alongside enforcement campaigns. Understanding how refusal affects your license, separate from how it may affect your criminal case, is an important part of deciding how to respond during a stop.

Persistent Drunk Driver Classification

A driver with a BAC of 0.15 percent or higher, or a driver who refuses chemical testing, can be classified as a Persistent Drunk Driver under Colorado law. This classification generally comes with an extended ignition interlock requirement, often around two years, that applies regardless of whether the underlying DUI case ends in a conviction, since the classification is tied to the administrative process rather than the criminal outcome alone. Because this classification attaches early in the process, it is worth reviewing with an attorney as soon as possible after an arrest, rather than waiting until the criminal case is further along.

The Financial and Personal Cost of a DUI Beyond Fines

The direct fines and court costs tied to a DUI conviction represent only part of the overall financial picture. A cost analysis published by No DUI Colorado, a state-supported impaired driving prevention organization, estimated that the average first-time DUI in Colorado costs a driver more than $13,000 once attorney fees, fines, increased insurance premiums, interlock device fees, and required education programs are added together.

Beyond the financial cost, a DUI case also consumes a significant amount of time, including court appearances, DMV hearings, required classes, and, in many cases, a mandatory Victim Impact Panel presented by Mothers Against Drunk Driving. Understanding the full scope of what a case may involve, not just the headline fine or jail range, can help you make more informed decisions from the very beginning of the process. Missed workdays for court dates and classes, transportation challenges during a license suspension, and the ongoing cost of an ignition interlock device can add up in ways that are easy to underestimate immediately after an arrest.

Your Legal Rights During a DUI Checkpoint or Stop

You have the right to remain silent beyond providing basic identifying information at a checkpoint or traffic stop, and you have the right to speak with an attorney before answering detailed questions about where you were coming from or how much you had to drink. Field sobriety exercises and roadside breath tests raise their own legal questions about reliability and administration, and how an officer conducted these tests can become an important issue in your defense.

Checkpoint-Specific Considerations

Sobriety checkpoints operate under specific legal requirements regarding how they are announced, staffed, and conducted, and deviations from those requirements can sometimes become relevant to a case. Drivers are generally permitted to turn away from a checkpoint before reaching it, provided the turn does not itself violate a traffic law, though this alone does not eliminate the possibility that an officer follows to observe further driving behavior. Officers are also expected to follow specific, documented procedures when administering field sobriety exercises, and any deviation from standardized instructions can become a point of dispute later in the case.
