BOISE, Idaho – Idaho’s “100 Deadliest Days” sit between Memorial Day and Labor Day. The Idaho Transportation Department tracks these days because they result in the highest amount of traffic deaths during the year.
In 2025, the “100 Deadliest Days” resulted in 88 deaths, according to preliminary data from the Idaho Office of Highway Safety.
60 of these people were killed in motor vehicle crashes. 23 of them were not wearing seatbelts. Nearly a quarter of them were motorcyclists.
“Every death is a tragedy,” Jo Middleton, Highway Safety Manager, said. “We can save lives by always wearing a seat belt, driving engaged, driving sober, and slowing down so everyone can make it home safely.”
The Idaho Transportation Department said that the top ten contributing circumstances to fatalities during the “100 Deadliest Days” were:
No seat belt useFailure to maintain laneSpeedingAlcohol impairmentInattentionDriving left of centerOvercorrectionNo helmetAsleep, drowsy or fatiguedImproper overtaking
The Idaho Transportation Department and the Idaho Office of Highway Safety said that they are working hard to change the trend by gathering and sharing critical data to increase public awareness about high-risk behaviors.
They also said they are expanding enforcement efforts with local law enforcement, creating outreach programs to engage communities and working to enhance and modernize infrastructure to improve roadway safety.
“These efforts show ITD and OHS’s deep commitment to protecting Idahoans and saving lives, not just tracking statistics,” wrote the Idaho Transportation Department.
