Impaired drivers in Colorado have been targeted as part of a summer campaign.

The Colorado Department of Transportation (CDOT) has been supported by the Colorado State Patrol and 74 local law enforcement agencies for The Heat Is On Summer Blitz.

During the 14-day enforcement period held earlier this month, there have been saturation patrols, sobriety checkpoints and additional law enforcement officers on duty dedicated to arresting impaired drivers.

“Colorado summers are meant to be memorable for the right reasons, not because you got a DUI,” said Col. Matthew C. Packard, chief of the Colorado State Patrol.

“Remember that DUIs carry serious consequences like jail time, fines, license suspension and more. Colorado State Patrol remains dedicated to removing impaired drivers from Colorado roads this summer.”

The period between Memorial Day and Labor Day — known as the 100 Deadliest Days of Summer — historically sees a spike in roadway crashes and fatalities across the state.

CDOT said during the 100 Deadliest Days period in 2024, 221 people were killed on Colorado roads, and about one-third of those fatal crashes involved an impaired driver.

Last year, there were 3,325 serious injuries on Colorado roads — and more than half (55%) occurred between Memorial Day and Labor Day.

CDOT’S preliminary data has shown during the recent Memorial Day Weekend DUI enforcement period concluded with 170 arrests across 85 participating agencies.
