Colorado starts holiday DUI crackdown Nov. 20–Dec. 3, targeting drunk driving with increased patrols and zero tolerance, after 23 alcohol-related deaths last Thanksgiving.

Colorado law enforcement agencies are launching a holiday DUI enforcement campaign starting November 20 and running through December 3, targeting impaired driving during the Thanksgiving travel period. The effort, part of CDOT’s “The Heat Is On” initiative, includes increased patrols across the state, with a focus on drunk driving, speeding, and reckless driving. Authorities emphasize a zero-tolerance policy, citing 423 DUI arrests and 23 alcohol-related fatalities during the 2024 Thanksgiving period. Extra enforcement is also planned for December 11–25. Officials urge drivers to plan ahead using designated drivers, ride-sharing, or public transit to prevent crashes.
