摘要：	Idaho Transportation Department (ITD) uses a variety of methods to help ensure safe travel on the state highway system following winter storm events. These methods include plowing, use of sand to improve traction, and use of salt and chemical compounds for deicing. While the use of salt and salt brines can help keep roads free of snow and ice, improving safety and mobility, questions have been raised about their contribution to wildlife-vehicle collisions (big-game animals may be attracted to salt used on roadways), their environmental impacts, and the corrosive effects on vehicles. To better understand these impacts, ITD requested a review of literature and state practices in each of these three areas of concern.
