The first thing you should do after colliding with a larger animal (if no person has been seriously injured) is to warn other road users by turning on the hazard warning lights and putting out a warning triangle at a suitable distance from the car.
If someone has been seriously injured in the accident and needs emergency care you should help that person first, before doing anything else.
If the animal you collided with has died and is on the road, you must, as long as it is safe to do so, try to move off it the road. Then contact the police and mark the location* as clearly as possible. If the animal you collided with has been injured and has disappeared into the forest, you must mark the exact location where the animal disappeared. This makes it easier for hunters to track the injured animal.
