The best position for an injured person is to place them on their side, with the knee of their top leg bent just a little, and their top arm placed so that the lower part of their hand is closer to the ground. This is to prevent the person from rolling over on their stomach, or on their back. This stabilizes the patient until help arrives.
An exception to this would be if the person has (or you suspect they have) a neck or back injury. In this case, the person would be place on their back, moving them as little as possible, and securing their head so they can't turn it to either side.
