July was the deadliest month so far in 2025 for impaired driving-related crashes in Colorado, with 26 fatalities reported. Since the beginning of the year, 124 people have died in traffic incidents involving suspected impaired drivers. As Labor Day weekend approaches, the Colorado Department of Transportation (CDOT) will join forces with the Colorado State Patrol and 56 local law enforcement agencies for The Heat Is On Labor Day Crackdown DUI enforcement period, which runs from August 15 to September 3.
Labor Day marks the conclusion of what is known as the “100 Deadliest Days of Summer,” a period between Memorial Day and Labor Day that typically sees an increase in fatal crashes. CDOT is encouraging motorists to plan ahead and arrange sober transportation options during this holiday weekend.
“July historically has some of the highest numbers of impaired-related crash fatalities when compared to other months. Impaired driving-related crashes, injuries and fatalities are tragic and completely avoidable,” said Col. Matthew C. Packard, chief of the Colorado State Patrol. “Don’t make excuses or exceptions. If you’ve been drinking, put down the keys and call a sober friend. You’ll be glad you did.”
Over the past five years, July has consistently ranked among the top months for impairment-related deaths on Colorado roads. During this year’s 20-day Labor Day enforcement period, drivers can expect increased patrols, sobriety checkpoints, and additional officers focused on arresting impaired drivers.
“No celebration or convenience is worth a life,” said CDOT’s Office of Transportation Safety Director Darrell Lingk. “Whether you use a ride-sharing service, taxi or public transportation, it’s always better to find a safe ride home than risk a DUI, crash or worse.”
Impaired driving carries serious legal consequences beyond safety risks. A DUI conviction in Colorado can result in jail time, license suspension, ignition interlock requirements, job loss, and an average financial burden of $13,530 due to fines, legal fees, higher insurance costs and lost work time. Certain professions such as trucking or law enforcement may also be jeopardized by a DUI conviction.
Earlier this year, CDOT began a campaign informing drivers about Colorado’s Expressed Consent Law: anyone operating a vehicle automatically consents to toxicology testing after a DUI arrest. Refusing such tests is illegal under state law and has become more common recently; doing so hinders road safety efforts statewide.
Following The Heat Is On Labor Day Crackdown enforcement period, another round focused on Fall Festivals will take place from September 11 through October 22.
CDOT is offering new footage from DUI checkpoints free for media use to show real-life interactions between law enforcement officers and drivers at these stops.
