With fall in the air and winter on the horizon Colorado drivers need to be on the lookout for migrating wildlife. Fall is the breeding season for elk, deer and moose so they are especially active during this time period. Males will pursue mates aggressively and may not be deterred by traffic. Bears are also especially active during the fall season as they prepare for hibernation. An average of 3,300 animal and vehicle collisions occurs each year in Colorado predominantly during the dawn and dusk hours. These collisions can result in injuries and even death to drivers and passengers. It is recommended that drivers reduce speeds and use extra caution while driving in migration corridors. Drivers in Northwest Colorado should be extra cautious as numbers from the Colorado Department of Transportation show some of the highest incidence of wildlife-vehicle collisions in the state occur in Moffat County.
