BOISE, ID — The Idaho Transportation Department’s Office of Highway Safety is encouraging drivers to make safe choices on the road this summer as the state enters what is traditionally known as the “100 Deadliest Days” between Memorial Day and Labor Day.
State officials said they are working with national partners to reframe the period as the “100 Safest Days of Summer” in an effort to promote safer driving habits and reduce fatal crashes statewide.
According to ITD, Idaho has seen improvements in summer crash fatalities since 2021, though officials say seat belt use, speeding and aggressive driving remain major concerns.
Idaho summer traffic fatalities
| Year | Fatalities Between Memorial Day and Labor Day |
|---|---|
| 2021 | 100 |
| 2022 | 81 |
| 2023 | 93 |
| 2024 | 82 |
| 2025 | 87 |
ITD said five Idaho counties — Camas, Franklin, Gem, Teton and Lewis — recorded zero traffic fatalities in 2025.
“Everyone wants zero fatalities for their family, and that is only possible when Idahoans make safe choices behind the wheel,” Office of Highway Safety Manager Josephine Middleton said. “We want drivers and passengers to be proactive about their safety as we head into the summer season.”
The department also reported improvements in safety for pedestrians and bicyclists after fatalities in those categories dropped by more than half following a spike in 2023.
Officials said nearly half of all people killed in passenger vehicles in 2024 were not wearing seat belts, while speeding and aggressive driving contributed to nearly half of all crashes statewide.
“As families and teens spend more time on the road, the safest choice is still the simplest one: buckle up, slow down, and stay focused,” Middleton said. “Together, we can make this Idaho’s safest summer yet.”
