BOISE—At least 92* people were killed in crashes during the 100 Deadliest Days on Idaho roads, according to preliminary data from the Idaho Transportation Department’s Office of Highway Safety (OHS). Vehicle crashes caused the majority of fatalities, followed by motorcycle crashes, and crashes involving pedestrians.
The 100 Deadliest Days are the time between Memorial Day and Labor Day when Idaho sees a spike in fatal and serious injury crashes. During this time more people are out of school or work, on vacations, and celebrating. This increase in traffic can lead to more distracted, aggressive, and impaired driving, making the roads more dangerous.
“Thinking about the gravity of the loss is heartbreaking. Ninety-two people are gone too soon, and families and communities across Idaho are mourning their loved ones,” Highway Safety Manager Josephine Middleton said. “It’s a solemn reminder of the importance of buckling up, putting down the distractions, and driving sober.”
OHS has compiled a preliminary list* of contributing factors to these fatalities. Please note that the numbers in this list add up to more than 92 because most crashes have more than one contributing factor. For example, a fatal crash could involve both impaired driving and no seat belt or inattention, speeding, and failing to yield, etc.
- No seat belt – 34
- Fail to maintain lane – 20
- Speed – 11
- Alcohol-impaired – 10
- Fail to yield – 10
- Inattention – 9
- Overcorrected – 5
- Drove left of center line – 5
- Improper overtaking – 4
- Wrong side or wrong way – 4
- Drug-impaired – 3
- Asleep, drowsy, or fatigued – 2
- Fail to obey a stop sign – 2
- Distracted in or on the vehicle (GPS, cell phone, etc.) – 2
- Improper lane change – 2
- Tire Defect – 1
