Snowmobiles have minimal environmental impact when used properly.
- Impact on grasses and other ground cover is minimal when vegetation is covered by at least four inches of snow. Since a snowmobile distributes its weight over a wide area, the pressure (weight per square inch) is much lower than the pressure created by a person on foot.
- Snowmobiles are built to federally mandated noise control standards. Engine noise has little or no effect on humans when trails are properly located away from residential or business areas.
- Scientific studies indicate that compaction of snow by snowmobiles has no negative effect on crops such as winter wheat or alfalfa.
- Compaction often eliminates snow mold and increases yields.
- Compaction may decrease soil erosion.
