1. Why does NDDOT spray water or liquids on the road on a clear day?
NDDOT is applying liquid ice melting material. The liquid melts snow and ice in temperatures well below zero degrees Fahrenheit and is generally a blend of water, salt, and a product that comes from sugar beets. Applying the liquids early helps melt snow and ice as they form and helps prevent snow or ice from bonding to the road. This method called anti-icing, or pre-treating, is a proactive approach to fighting snow and ice buildup. Effective anti-icing can reduce costs, reduce environmental impacts, improve service to the motorists, and enhance safety.
