Any person who, while driving a motor vehicle, is involved in a collision with a deer shall, if the deer is killed, immediately notify the nearest conservation ranger or sheriff's office. If there exists a charitable institution or prison within the county which can make use of the carcass, the conservation ranger may deliver the carcass to the institution for consumption and shall obtain receipts therefor. If no such institution exists within the county and there is no cause to question the accidental killing of the deer, the conservation ranger may, at his discretion, award the carcass to the person who hit the deer, to be possessed and consumed only by the immediate family of such person. Receipts shall be acquired for a deer so awarded.
