Treasure Valley DUI Task Force Launches Idaho Cinco de Mayo Emphasis Operation
The Treasure Valley DUI Task Force launched a two-day DUI enforcement emphasis on Friday evening ahead of Cinco de Mayo, a holiday frequently associated with alcohol-fueled celebrations. The operation, announced by the Idaho State Police, runs through Saturday and involves law enforcement agencies across the Treasure Valley — including the Nampa Police Department, the Caldwell Police Department, and the Canyon County Sheriff’s Office — working in coordination to identify and remove impaired drivers from Canyon County and Treasure Valley roadways.
Background: A Coordinated Regional Effort
The Treasure Valley DUI Task Force is a multi-agency operation designed to concentrate law enforcement resources during periods of elevated risk on Idaho roads. The task force brings together agencies from both Canyon County and Ada County, including the Idaho State Police, the Meridian Police Department, the Boise Police Department, the Ada County Sheriff’s Office, and the Garden City Police Department.
Canyon County residents who travel the highways and surface streets connecting Nampa, Caldwell, and the broader Treasure Valley corridor face real risk whenever impaired drivers are on the road. Multi-agency operations like this one are among the most effective tools law enforcement has to reduce that risk in a concentrated period.
The task force’s reach extends across a wide swath of southwestern Idaho, serving Ada, Canyon, Gem, Owyhee, Payette, and several other counties in District 3 — Western Idaho.
DUI Arrests in Prior Operation Underscore the Stakes
During the same operation period in 2025, the Treasure Valley DUI Task Force arrested 37 impaired drivers over the course of the two-day emphasis. That figure underscores why law enforcement agencies treat holidays like Cinco de Mayo as high-priority enforcement windows.
The goal of the current operation, according to the Idaho State Police, is to prevent crashes and keep the public safe — a straightforward mission that Canyon County families traveling area roads this weekend can benefit from directly.
For Canyon County communities like Nampa and Caldwell, where major roadways serve tens of thousands of commuters and families daily, removing even a handful of impaired drivers from circulation during a high-risk holiday weekend can make a measurable difference. Law enforcement officers across the Treasure Valley deserve recognition for volunteering extra effort during holiday periods to keep roads safe.

Impact on Canyon County Residents
Canyon County residents heading out to celebrate Cinco de Mayo — or simply traveling for everyday purposes this weekend — should be aware that increased law enforcement presence will be visible on roads throughout the region. Officers will be actively looking for signs of impaired driving, and the task force’s multi-agency makeup means coordination across county lines.
Families near Lake Lowell, along the State Highway 55 corridor, and on the arterial roads connecting Nampa and Caldwell to the greater Treasure Valley should exercise additional caution this weekend and plan for designated drivers or alternative transportation if they plan to consume alcohol.
As the summer recreation season picks up across Canyon County — including at Lake Lowell, which opened for boating on April 15 — law enforcement presence during holiday weekends is expected to remain elevated. Residents are encouraged to report suspected impaired drivers immediately rather than waiting or attempting to intervene themselves.
What Comes Next: How to Report an Impaired Driver
The Idaho State Police is asking the public to assist in the effort. If you observe a suspected impaired driver on any Idaho road this weekend, call 911 or dial ISP (477) to reach Idaho State Police dispatch directly.
