BLM reminds public to drive only on existing roads ROCK SPRINGS, Wyo. – There are hundreds of miles of roads to use when exploring public land in Wyoming. The Bureau of Land Management High Desert District (HDD) reminds people that it is illegal to travel off existing roads in a motorized vehicle. A citation for driving a motorized vehicle off existing roads or in a closed area, can result in fines. Off-road driving can cause significant damage anytime, but spring soils are especially susceptible. The resulting damage can cause erosion and serious impacts to important wildlife habitat. Another factor to consider is personal safety, e.g., not getting stranded on muddy or washed-out roads.
