It’s Wednesday, November 25, 2026. You had a drink while cooking, took an edible later in the evening, and now a friend expects you at another Thanksgiving gathering. The question at the holiday table is simple: Are you too high or buzzed to drive? Because cannabis is legal in Colorado, you may view that decision differently from driving after alcohol. Under Colorado law, it isn’t different.
A legal cannabis purchase, a medical marijuana registration, or a belief that you feel fine doesn’t give you permission to drive while impaired. Colorado DUI law applies to alcohol, marijuana, prescription medication, and other drugs. If you’re arrested, the criminal charge is only one part of the process. A separate Colorado DMV license case begins quickly, and its deadline continues through the holiday week.
Thanksgiving Week Brings High-Visibility DUI Enforcement
You should expect increased enforcement on Colorado roads during Thanksgiving week. Thanksgiving Eve, often called Blackout Wednesday, brings restaurant gatherings, house parties, and trips between friends’ homes. Thanksgiving Day and the weekend add long-distance travel, football gatherings, and alcohol or cannabis use that may continue for several hours.
Colorado’s Heat Is On campaign uses high-visibility enforcement periods around holidays and major events. These efforts may involve the Colorado State Patrol and local law enforcement agencies conducting sobriety checkpoints where legally authorized and saturation patrols, which place additional officers in areas associated with impaired drivers.
As of November 13, 2026, CDOT had not announced a 2026 Thanksgiving Heat Is On enforcement period. The most recent confirmed Thanksgiving campaign ran from November 20 through December 3, 2025, with the Colorado State Patrol and 68 local agencies participating. Those dates and agency numbers are historical and don’t predict the 2026 schedule.
CDOT reported 423 DUI arrests during Colorado’s 2024 Thanksgiving Weekend enforcement period, nearly 20 percent more than in 2023. That figure doesn’t establish that every arrest led to a conviction. It does show why you should arrange transportation before the first drink or edible rather than make a last-minute judgment about whether you are “okay to drive.”
Legal Cannabis Doesn’t Create a Right to Drive Impaired
Colorado law distinguishes between legally possessing cannabis and driving after using it. A DUI charge alleges that alcohol, drugs, or a combination substantially affected your ability to drive safely. A DWAI, meaning driving while ability impaired, involves impairment to the slightest degree. The state must prove the charge, but you don’t need to be falling asleep at the wheel or unable to finish a drive for an officer to investigate a possible DWAI.
Colorado’s THC rule often creates confusion. When a blood test shows 5 nanograms or more of delta-9 THC per milliliter of whole blood, a jury is permitted to infer that you were under the influence. This is a permissible inference, not a mandatory conclusion or a bright-line limit that makes driving lawful below 5 nanograms. A lower result doesn’t automatically end an allegation, while a result at or above that level doesn’t replace the prosecution’s burden to prove impairment.
Investigators may consider your driving, the officer’s observations, roadside testing, statements, body camera footage, and other evidence. Legal possession also doesn’t resolve whether a stop or search was justified. The firm’s April post on marijuana odor and probable cause explains how that issue can arise during a vehicle investigation.
A medical marijuana registration doesn’t change the driving rule. Colorado law states that lawful entitlement to use a drug, including through a medical marijuana registration, isn’t a defense to DUI or DWAI. The same principle applies to a prescription drug that affects your driving ability: legal use and safe driving are separate questions.
Edibles require particular caution because their effects may arrive later and last longer than expected. You may feel different an hour after taking an edible, just as you’re preparing to leave. Products marketed as Delta-8, hemp-derived THC, or similar alternatives don’t create a driving exception. Colorado also restricts open marijuana containers in a vehicle’s passenger area when there’s evidence that marijuana was consumed in the vehicle. Keep cannabis sealed and stored appropriately, but remember that proper storage doesn’t answer whether you’re safe to drive.
Alcohol & Cannabis Can Both Matter in a DUI Investigation
When you mix alcohol and cannabis, one number doesn’t tell the entire story. You might focus on having only one drink or assume that a small edible doesn’t matter because you use cannabis regularly. Officers and prosecutors may consider the combined effects rather than evaluate each substance in isolation.
Colorado’s Division of Criminal Justice reported that, among people involved in a crash and convicted of DUI whose toxicology data appeared in a report using information through 2022, 41 percent had alcohol and THC in their systems. Another 48 percent had alcohol, cannabis, and another drug present. Those findings don’t prove that every substance caused a particular crash, but they show how frequently tested cases involved multiple substances.
There’s no separate holiday rule for drug-impaired driving. A Thanksgiving DUI in Colorado may involve alcohol, marijuana, prescription medication, or a combination. Colorado’s statute doesn’t require a distinct drug-driving charge simply because cannabis forms part of the allegation.
Trying to calculate whether two substances will “cancel out” or remain below a personal limit isn’t a reliable transportation plan. If you have used alcohol and cannabis during the same evening, don’t drive. Arrange a sober driver, rideshare, or overnight stay before dinner begins.
A Traffic Stop Creates a Separate Evidence Trail
A DUI investigation often begins with an alleged traffic issue, such as speeding, lane movement, a signal violation, or an equipment problem. During the stop, an officer may ask questions, observe your speech and appearance, request roadside tests, and seek a breath or blood test. An arrest doesn’t establish guilt, and each stage matters when the evidence is reviewed.
Colorado permits DUI arrests based on observed signs of impairment even when your blood alcohol concentration is below 0.05 percent. Chemical testing also involves procedures, records, and handling requirements. Breath-machine calibration records, blood collection records, laboratory processing, and lab-accreditation issues may affect how test evidence is evaluated.
Keep every paper you receive after an arrest. While the details are fresh, write down where the stop occurred, what the officer said, when tests were requested, and whether you received a notice about your license. A review of the case should address the reason for the stop, roadside procedures, arrest reports, available body camera footage, and chemical-test records rather than assume the report tells the whole story.
The DMV Clock Runs Through the Holiday
The most immediate deadline after a Thanksgiving DUI in Colorado may arrive before your first court date. The Expressed Consent Hearing is an administrative proceeding through the Colorado DMV concerning your driving privilege. It’s separate from the criminal DUI or DWAI case.
If you took a breath test or refused testing, you generally have seven calendar days from the date of arrest to request an Expressed Consent Hearing. If your case involves a blood test, the seven-calendar-day period generally begins on the date listed on the DMV letter. Missing the deadline waives the hearing right and results in license revocation.
The DMV doesn’t wait for the criminal case to finish before acting on your driving privilege. Your court case may involve later filings, hearings, negotiations, or trial preparation, but the administrative track follows its own timeline. The firm’s August guide to the seven-day DMV deadline explains this separate process in more detail.
A Wednesday, November 25 arrest makes the timing easy to underestimate. Seven calendar days includes Thanksgiving Day, the weekend, travel days, and the beginning of the following week. A holiday closure or busy work schedule doesn’t extend the deadline. Review the notice, test type, arrest date, and any DMV letter promptly rather than waiting until the seventh day.
Once you properly request a hearing, the DMV issues additional paperwork and a hearing notice. The hearing gives you an opportunity to address the DMV allegations, but only if your request is timely. The license issue may have practical consequences even with a first-offense DUI allegation, while a felony DUI allegation may involve prior convictions or serious injury. In either situation, the DMV deadline remains separate from the eventual path of the criminal case.
Plan the Ride Before the First Drink or Edible
Your safest transportation decision happens before the meal starts. Make the plan specific enough that no one needs to improvise at the end of the night:
- Choose a designated driver who will remain genuinely sober.
- Schedule a rideshare before peak pickup times.
- Use public transportation when it fits the route.
- Arrange in advance to stay overnight.
- If you’re sober, offer a ride to someone without a safe plan.
A designated driver isn’t simply the person who drank or used the least. Someone who has used cannabis, taken a sedating prescription medication, or had drinks earlier in the evening shouldn’t be assigned the drive home based on a group guess. Decide where the keys will go and how everyone will get home before the gathering begins.
Rideshare promotions and ride-credit programs sometimes appear during holiday enforcement periods, but CDOT had not announced a 2026 Thanksgiving ride-credit code as of November 13, 2026. Don’t build your plan around an unconfirmed code. A paid ride or planned overnight stay prevents you from trying to solve transportation after alcohol or cannabis has affected your judgment.
If an arrest has already happened, focus first on the paperwork. Preserve your documents, identify the Expressed Consent deadline, and avoid drawing conclusions from a breath, blood, or THC result before the underlying records are reviewed. That review should account for the stop, the officer’s observations, field tests, chemical testing, police reports, available video, and the DMV process.
