Avoiding riding at night on snowmobiles is particularly advisable because many animals are more active during twilight and nighttime hours. This increased animal activity raises the risk of collisions between snowmobiles and wildlife, which can lead to serious accidents and injuries. Animals, such as deer and moose, may cross trails unexpectedly, and their dark coloration makes them harder to see in low-light conditions.
While it's true that there may be fewer vehicles on the road at night, that reduces the risk of collision with other vehicles rather than addressing the specific hazards associated with wildlife. Improved visibility at night is not accurate; visibility typically decreases after sunset, which can further increase risks. Lastly, the availability of trails does fluctuate seasonally, but this does not have a direct impact on the specific dangers posed by nighttime riding.
Thus, the primary safety concern related to riding at night is the heightened activity of wildlife and the associated risks it presents to snowmobilers.
