Idaho’s statistics do not classify these injuries. The state’s accident reports use the KABCO scale to rate injuries at the accident scene. This acronym stands for the following:
- K: A fatal injury
- A: An incapacitating injury that prevents the victim from normal activities
- B: A non-incapacitating injury that is visible
- C: A possible injury that causes complaints but without an evident injury
- O: No injury evident or reported
One way to compare the traffic safety of cities with different populations is to calculate the injury accident rate. In 2023, Idaho Falls had the state’s lowest rate at 2.3 fatal and injury crashes per 1,000 residents. For comparison, Meridian led the state with a fatal or injury crash rate of 6.2 per 1,000 residents.
Causes of Idaho Falls Car Collisions
Across the state, the leading causes of car accidents include the following:
Impaired Driving
In Idaho, 22% of fatal crashes were caused by a driver impaired by drugs or alcohol. Intoxicants affect a driver’s judgment, reflexes, and focus. As a result, the driver is less able to identify and respond to traffic and road conditions.
Inattentive and Distracted Driving
Inattentive and distracted driving are the top reasons for injury crashes in Idaho. Distracted driving occurs when a task takes a driver’s hands, mind, or eyes away from driving. Inattentive driving happens when drivers fail to focus their entire attention on driving. Here are some examples of tasks that can lead to inattentive or distracted driving:
- Daydreaming
- Talking
- Writing or reading texts
- Adjusting your stereo
- Eating or drinking
Distracted drivers, like impaired drivers, cannot spot or respond to changing conditions, such as traffic slowing ahead of them.
Failing To Yield the Right of Way
Most intersection collisions happen when a driver fails to yield the right of way. The right-of-way rules determine which driver can proceed while the others must wait.

However, despite its good traffic crash record, you can improve your odds of avoiding a crash by driving sober, exercising caution at intersections, and paying attention to the road.
