Why This Is Important

Even one death on Idaho's highways is one death too many.  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. 

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.
