If you hit a cow or a horse with your vehicle, the first thing you should do is notify the police that it happened. The next thing you should do, if you’re able, is collect evidence. Things like hoofprints can be washed away in the rain, an opened gate can be quickly closed, and that evidence will disappear unless photos are taken at the scene. Then, if you’re injured as a result of hitting a cow or a horse, you should go see a doctor about your injuries. Then finally, you should contact an attorney who has experience with these kinds of claims to discuss what your options are.
