With an average of more than 1,300 DUI arrests each month this year, Colorado is on track to surpass 16,000 total DUI arrests by the end of the year, according to CDOT and the Colorado Department of Insurance.

CDOT will support the Colorado State Patrol and 61 local law enforcement agencies for The Heat Is On New Year’s Eve DUI enforcement period.

The enhanced enforcement will occur between December 26, 2025, and January 1, 2026.

The Heat Is On campaign runs throughout the year, with 15 specific high-visibility impaired-driving enforcement periods centered on national holidays and large public events, the CDI said.

During last year’s New Year’s Eve enforcement period, Colorado law enforcement made 207 DUI arrests. Throughout all enforcement periods this year alone, there have been 4,916 DUI arrests.

Following New Year’s Eve, the next DUI enforcement period will be Winter Blitz from Jan. 8 to 21, 2026.

“Driving under the influence — whether you’ve consumed alcohol or cannabis — puts you at risk of a DUI arrest or crash,” said Col. Matthew C. Packard, chief of the Colorado State Patrol. “This New Year’s Eve, law enforcement across the state is prepared to conduct saturation patrols and arrest impaired drivers. Don’t drop the ball this New Year’s holiday — choose to drive sober and encourage others to do the same.”

Colorado State Patrol data shows that impaired driving citations spike between 10 p.m. and 2 a.m. — the timeframe of most New Year’s celebrations.

Even if blood alcohol content (BAC) is less than 0.05 percent, a DUI arrest can still be made if an officer observes signs of impairment.

To curb DUIs and impairment-related crashes on Colorado roadways this new year, Uber and Mothers Against Drunk Driving (MADD) are offering an $8 discount using Uber Voucher code JOYFULCO25 in the Uber app. The discount is valid for one-time use within the Denver metro area through January 2.

“So far in 2025, 223 people have died on Colorado roads in crashes involving impaired drivers. That’s 223 lives cut short, families affected and friends lost,” said CDOT’s Office of Transportation Safety Director Darrell Lingk. “If you plan to drink, use a ride-share service, public transportation, or a designated driver to get home safely.”

Under Colorado’s Expressed Consent Law, a driver in the state automatically consents to a toxicology test following a DUI arrest. Colorado has seen an increase in drivers who refuse a toxicology test in recent years. Refusing a test is illegal, and it hinders efforts to keep Colorado roads safe from impaired drivers.
