Idaho Traveler shows you the current conditions of major roads and highways throughout Idaho. You can view traffic cameras, read alerts about road closures, get stats from weather stations, and read roadside signboard messages. You can also view road overlays that tell you the current surface conditions.
All this is displayed on an easy-to-use map. Only interested in certain areas? You can define your own regions and quickly view them, or use one of the several predefined areas.
