A study conducted by Marquette University found that, when winter storms turn roads to ice, deicing them with salt reduces accidents by 88 percent and injuries by 85 percent.
Road salt also saves money. When snow and ice make roads impassable, it can cost state economies as much as $700 million a day—and these are losses that salt can mitigate.
All told, deicing with road salt pays for itself in just 25 minutes. If only every investment were as sure a thing.
