Labor Day weekend can bring increased impaired-driving enforcement across Colorado. The Colorado Department of Transportation runs The Heat Is On throughout the year with high-visibility enforcement periods tied to national holidays and major public events. These periods can include saturation patrols, sobriety checkpoints, and added officers focused on impaired driving. CDOT also identifies the period from Memorial Day through Labor Day as the 100 Deadliest Days of Summer.
The legal standards for a Colorado DUI or DWAI case do not change because of a holiday. An arrest does not establish guilt. The prosecution must still prove the required elements of the charge, and the legality of the stop, the officer’s observations, roadside exercises, chemical testing, video, statements, and other evidence may all require review.
A Colorado DUI case can also move on two separate tracks. One is the criminal court case. The other is the administrative process through the Colorado Division of Motor Vehicles. The DMV process can affect driving privileges before the criminal case is resolved, and its deadlines can arrive quickly.
Why Labor Day Weekend Can Mean More DUI Enforcement 
Labor Day falls near the end of Colorado’s summer travel season. CDOT’s The Heat Is On campaign uses high-visibility impaired-driving enforcement periods throughout the year. Specific dates, participating agencies, and enforcement plans can change from year to year.
Extra enforcement does not create a separate Labor Day DUI offense. An ordinary traffic stop still needs a lawful basis. Sobriety checkpoints are evaluated under different constitutional rules, and Colorado courts have upheld properly conducted checkpoints. The planning and operation of a specific checkpoint can still matter when a DUI arrest begins at a roadblock.

What Can Lead to a DUI Stop in Colorado?
Many DUI investigations begin with a traffic stop. An officer may report speeding, drifting, crossing or touching lane markings, making a wide turn, failing to signal, braking late, driving unusually slowly, or operating a vehicle with an equipment problem.
The legal sufficiency of a stop depends on the full circumstances. A reported driving behavior does not automatically establish impairment.
After approaching the vehicle, an officer may document observations such as:
- Odor of alcohol or marijuana
• Red or watery eyes
• Unusual or slurred speech
• Inconsistent answers
• Open containers
• Difficulty locating documents
• Coordination concerns
• Statements about alcohol, cannabis, medication, or other substances
Those observations may become evidence, but no single observation proves DUI or DWAI by itself.
An officer may also ask a driver to perform roadside sobriety exercises. Common exercises include the horizontal gaze nystagmus test, walk-and-turn exercise, and one-leg stand. Performance can be affected by road conditions, lighting, traffic, footwear, fatigue, anxiety, age, injuries, medical conditions, and the instructions provided by the officer.

Colorado DUI, DWAI, and BAC Levels
Colorado distinguishes between DUI and DWAI.
DUI generally applies when alcohol, one or more drugs, or a combination affects a person to a degree that the person is substantially incapable, mentally or physically, of exercising clear judgment, sufficient physical control, or due care in the safe operation of a vehicle.
DWAI applies when alcohol, one or more drugs, or a combination affects a person to the slightest degree so that the person is less able than usual to exercise clear judgment, sufficient physical control, or due care in the safe operation of a vehicle.
Colorado also recognizes DUI per se. A driver commits DUI per se when the driver’s blood alcohol concentration is 0.08 or more at the time of driving or within two hours after driving, subject to the defenses and proof rules in Colorado law.
A BAC above 0.05 but below 0.08 creates a permissible inference that the driver’s ability was impaired by alcohol. A chemical test is not the only evidence that prosecutors may use. Driving behavior, officer observations, statements, video, witness testimony, and other evidence can also be part of the case.

Alcohol Is Not the Only Basis for a Colorado DUI Arrest
Colorado DUI law also covers drugs. A case may involve cannabis, prescription medication, illegal drugs, over-the-counter medication, or a combination of alcohol and drugs.
Drug DUI investigations may include:
- Driving observations
• Roadside sobriety exercises
• Body-camera and dash-camera footage
• Statements
• A Drug Recognition Expert evaluation
• Blood testing
• Toxicology reports
• The timing between driving and sample collection
In marijuana cases, Colorado law allows a permissible inference that a driver was under the influence of one or more drugs when a blood test shows five nanograms or more of delta-9 THC per milliliter of whole blood. That inference does not eliminate the need to evaluate the rest of the evidence.
Excellent Attorney
Collin McCallin performed EXCELLENTLY with my case. He kept in consistent contact with me throughout and showed diligence and extreme care for what I was dealing with.
He worked effectively with the district attorney to resolve my case, and I could not be more pleased with the work. Thanks again!

What Happens After a Labor Day DUI Arrest?
After a DUI arrest, the driver will usually receive paperwork that starts the criminal court process. The documents may include a summons, bond conditions, a court date, and other instructions. The local prosecutor decides which charges to pursue.
The DMV process is separate. Colorado DMV guidance describes the criminal court case and the administrative license case as two distinct paths with different timelines and requirements. A result in one process does not automatically control the other.
The DMV hearing deadline can be critical:
- If a breath test was given at the time of the stop, the hearing generally must be requested within seven days of the arrest.
• If a chemical test was refused at the time of the stop, the hearing generally must be requested within seven days of the arrest.
• If a blood test was completed, the seven-day period generally begins when the driver receives notice of the blood-test result.
DMV DEADLINE: Depending on the test or refusal, the seven-day clock can begin at the arrest or when the blood-test result is received. A future court date does not preserve a separate DMV hearing deadline.

What Is Colorado’s Express Consent Law?
Colorado’s Express Consent law requires a driver to cooperate with chemical testing when an officer has the legal grounds required by statute. A roadside handheld breath test is different from the post-arrest evidentiary breath or blood testing used for the Express Consent process.
A refusal can create separate driver’s license consequences and may also become evidence in the criminal case. Colorado DMV guidance states that a first refusal results in a one-year revocation and a Persistent Drunk Driver designation. Reinstatement requirements can include Level II alcohol and drug education and treatment, ignition interlock, SR-22 insurance, and other requirements based on the driver’s record and restraint.
The exact consequences depend on the driver’s history, the type of test, the result, any refusal, and other facts. Review every DMV document promptly rather than treating the criminal court date as the only deadline.

Possible Penalties for a Colorado DUI or DWAI
Penalties depend on the offense, prior record, BAC, and other facts.
A first DUI or DUI per se conviction can include:
- A $600 to $1,000 fine
• 48 to 96 hours of useful public service
• Jail time
• Probation and treatment requirements in some cases
• Separate driver’s license consequences through the DMV
For a first DUI per se conviction, Colorado law provides a jail range of 5 to 364 days. A BAC of 0.20 or higher can trigger a higher minimum jail term under Colorado law.
A first DWAI conviction can include:
- 2 to 180 days in jail
• A $200 to $500 fine
• 24 to 48 hours of useful public service
Those ranges do not predict the result in a specific case. Prior convictions, refusal issues, injuries, and other circumstances can change the potential consequences.
A new DUI, DUI per se, or DWAI can become a class 4 felony when the offense occurs after three or more qualifying prior convictions arising from separate and distinct criminal episodes.

What Evidence Can Matter in a Labor Day DUI Defense?
A holiday enforcement campaign does not decide whether the government can prove a DUI or DWAI charge. A defense review can compare the officer’s report with video, testing records, laboratory documents, and other evidence.
The review may include:
- The legal basis for the traffic stop
• Checkpoint planning and operating procedures
• Body-camera and dash-camera footage
• Dispatch records
• Roadside exercise instructions and performance
• Road, lighting, traffic, weather, and footwear conditions
• Breath-testing records and device maintenance
• Blood collection, labeling, storage, transport, chain of custody, and laboratory records
• Statements made before and after arrest
• Medical conditions, injuries, medications, fatigue, or anxiety
• Witness statements
• Receipts, photographs, messages, and location information
• The time between driving and chemical testing
• Whether the prosecution can prove driving or actual physical control
• Whether the evidence proves the required level of impairment
No single defense applies to every case. The strongest issue may involve the stop, checkpoint, officer observations, roadside exercises, chemical testing, statements, or another part of the investigation.
What Should You Do After a Labor Day DUI Arrest?
The first days after an arrest can matter because DMV deadlines may arrive before the criminal case develops.
Consider these steps:
- Keep every document from police, the jail, the court, and the DMV.
• Photograph or scan the paperwork so that you have backup copies.
• Write down what you remember about the stop, route, officer instructions, roadside exercises, arrest, and testing.
• Record the timing of alcohol, cannabis, prescription medication, or other substances if relevant.
• Preserve receipts, photographs, messages, location information, parking records, and witness contact information.
• Keep the clothing and footwear worn during roadside exercises if their condition may matter.
• Avoid altering records or evidence.
• Avoid posting details about the case on social media.
• Confirm your current driving status before driving.
• Calendar both court dates and DMV deadlines.
• Have the evidence and deadlines reviewed before making major case decisions.
The criminal case and the license case can follow different timelines. A later court date does not mean that the driver’s license remains valid or that a DMV deadline has been preserved.
