Black ice is a treacherous killer on Utah highways.
In high mountain areas where the winter sun rises late in the morning or may never warm the highway at all, black ice is patchy. Slow down to stay in control, especially along highways sheltered by the mountains. An ounce of prevention should include a full tank of gas and some water. Visitors from the city may be delighted, but are generally unprepared for the hazards associated with critters grazing along the highway. In areas where open grazing is permitted, frequent accidents occur involving cattle.
