Smart Breathalyzers in Colorado: Are AI Devices the Future of DUI Arrests?

By Colorado Attorney-at-law on May 21, 2025

In recent years, technological innovation has touched nearly every aspect of modern life—including the tools law enforcement uses in criminal investigations. One of the latest developments that’s gaining traction in Colorado and beyond is the integration of artificial intelligence (AI) into smart breathalyzer devices.

What does that mean for individuals facing DUI charges in Colorado? Are AI-powered breathalyzers truly the future of DUI arrests? If so, this will bring new challenges and opportunities for defending drivers against DUI charges.

At Whitaker & Penix, LLC, we have extensive experience defending clients against DUI charges across the 6th Judicial District. As former prosecutors and seasoned trial attorneys, we stay up to date on emerging legal and technological trends so we can deliver strong, informed defense strategies.

What Are Smart Breathalyzers?

Smart breathalyzers are digital devices that go beyond simply measuring a person’s blood alcohol concentration (BAC). These AI-enhanced tools often include features such as:

  • Cloud Connectivity: Real-time data transfer to law enforcement databases.
  • Facial Recognition: To verify the identity of the person taking the test.
  • Location Tracking: To confirm where and when the test was taken.
  • AI Algorithms: To detect anomalies or inconsistencies in readings.

Some models are even designed for continuous remote monitoring, often used as part of probation or pretrial release conditions.

Legal Challenges Posed by AI Breathalyzers

While smart breathalyzers may seem like a silver bullet for law enforcement, their use raises several red flags from a legal standpoint.

Data Privacy

These devices often collect personal data, including facial images, GPS location, and timestamps. This information is stored and transmitted via cloud servers, which creates questions about who owns the data and how it may be used in other investigations or contexts. Defendants may have valid constitutional concerns under the Fourth Amendment.

Software Transparency

If AI is used to interpret results or flag inconsistencies, Breckenridge DUI defense attorneys have a right to know how those algorithms work. Unfortunately, many AI-driven tools are protected by proprietary code, making it nearly impossible to scrutinize the software for errors or bias. This undermines a defendant’s ability to challenge the validity of the results.

Chain of Custody Issues

With data automatically uploaded to cloud servers, questions can arise about how securely that information was handled and whether it was subject to tampering or unauthorized access. The chain of custody must be airtight for any evidence to be admissible in court.

False Positives and Calibration Errors

Despite the promise of accuracy, no device is infallible. Environmental conditions, physiological differences, or even recent use of mouthwash can still lead to false positives for DUI testing. Additionally, if calibration logs are maintained only digitally and become corrupted, critical evidence may be lost or compromised.

Are AI Breathalyzers Admissible in Colorado Courts?

The short answer is: not always. For breathalyzer results to be admissible in Colorado, the device used must be on the state’s approved list, and the test must be administered in accordance with strict procedural guidelines.

If law enforcement uses a smart or AI-enabled device that isn’t approved or fails to follow protocols, the results may be challenged and potentially excluded. Even with court-approved devices, defense attorneys can question whether the device was properly calibrated, whether the officer was trained to use it, and whether the AI software introduced any bias or misinterpretation.

What If You’re Asked to Use a Smart Breathalyzer?

Under Colorado’s express consent law, drivers are generally required to submit to a chemical test (breath or blood) after a lawful DUI arrest. Refusing can lead to automatic license suspension and other penalties. However, the specifics of how the test is administered and on what type of device can still be contested.

You are not required to submit to a preliminary roadside breath test (commonly known as a PBT) before arrest. These devices, which may include smart technology, are not as reliable and are primarily used to establish probable cause.

If you’re asked to take a roadside test, you can respectfully decline. If arrested, your best move is to comply with the test and then immediately contact a qualified DUI defense attorney to evaluate the circumstances and prepare your defense.

How We Defend Breckenridge DUI Cases Involving Smart Breathalyzers

At Whitaker & Penix, LLC, we take a comprehensive and strategic approach to DUI defense. If your case involves a smart or AI breathalyzer, we’ll examine every aspect of the evidence, including:

  • Whether the device is approved and properly maintained.
  • Whether the officer followed all necessary protocols.
  • How the data was stored, accessed, and transferred.
  • The role of AI in interpreting results and whether that role is legally valid.

We work to identify weak points in the prosecution’s case, uncover procedural errors, and raise challenges to the credibility of the breathalyzer evidence itself. Our experience as former prosecutors gives us an edge—we know how these cases are built and how to take them apart.

Is This the Future of DUI Enforcement?

AI-enhanced tools like smart breathalyzers may become more common in DUI enforcement, but that doesn’t mean they’re beyond challenge. In fact, the more complex the device, the more opportunities there are for error. As technology evolves, so must our legal defenses.

What remains unchanged is the need for experienced, aggressive legal representation. No device—AI or otherwise—can replace the role of a seasoned defense attorney in protecting your rights, ensuring fair treatment, and challenging questionable evidence.
