1.34

Why This Is Important

Even one death on Idaho's highways is one death too many.  An estimated total of 1113 people lost their lives on Idaho roads between 2013 and 2017.  Each death is a personal tragedy for the individual's family and friends, and has an enormous financial cost to the community.  Every life counts.

How We Measure It

The measure is calculated by dividing the number of fatalities that occur over a five-year period by the number of vehicle miles traveled over the same five-year period.  The five-year rate for 2013 to 2017 is 1.33 fatalities per 100 million vehicle miles traveled. (Note: This rate is based on Idaho's estimate of vehicle miles traveled rather than the required Federal estimate which is not yet available.) Next year, the low fatality number from 2014 falls off the five-year average.

What We're Doing About It

The department advances programs to eliminate traffic deaths, serious injuries, and economic losses.  These programs focus on engineering, education, enforcement and emergency response.
