Is your friend okay? The guy who hit him is going to pay dearly for that. Also, tell your friend to not sign off on anything as far as personal injuries. One of my dairy farmers was hit from behind, they ran into the manure spreader behind one of the bigger tractors. It shoved him across the road, and tore up the back of the spreader, the guys truck and something under the tractor where the hitch bar was or something. The bad thing was, that about 2 days later, he went to get up and couldn't move one leg and had a headache that was so severe they called the rescue squad. It had done some damage to his spine from the jolt. He spent a couple of years in physical therapy and still has back problems. This is a guy who doesn't believe in "playing the system" he was really messed up.
