Animals on the road can be dangerous. While city drivers may encounter rabbits, squirrels, and an occasional cat or dog, or even a gaggle of geese attempting to cross the road on foot, rural drivers tend to encounter deer, moose, and other animals that can cause serious damage to the vehicle and even kill the occupants in a collision. In the dark, it can be almost impossible to see the animals until they are in front of the vehicle, making it difficult to avoid a crash. Cattle or other farm animals can also be a problem at times.
