BOISE, ID – Preliminary data from the Idaho Office of Highway Safety (OHS) shows that 88 people were killed in crashes across the state during the 2025 “100 Deadliest Days,” the period between Memorial Day and Labor Day when traffic deaths historically spike.
Of the 60 people killed in motor vehicle crashes, 23 were not wearing seat belts. Nearly one-quarter of all fatalities were motorcyclists. Highway Safety Manager Jo Middleton emphasized that lives can be saved with simple precautions: “Every death is a tragedy. 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 (ITD) and OHS said they are taking multiple steps to address the trend, including statewide public-awareness campaigns, increased enforcement with local law enforcement, community outreach programs, and infrastructure improvements aimed at reducing crash severity.
