(a) The commissioner shall prepare and currently maintain a master road and highway map which will show all of the state roads and highways located, created and classified as provided by law; the mileage of roads and highways; the status of improvements; and travel conditions when practical. The commissioner may make economical reproductions of the map for official use and public information purposes, including a digital road map. The goal is for the maps to be computerized and searchable by the public to map routes for travel throughout the state.
(b) The digital road map shall indicate whether public roads are unpaved and unimproved, unpaved and improved, unlined and paved, or lined and paved. The digital road map shall further indicate the types of vehicles that may use each road, including full-size vehicles and off-highway vehicles, such as all-terrain vehicles, utility-terrain vehicles, motorcycles and off-road vehicles.
