A police dashboard camera catches a spectacular crash involving a Kentucky police officer. Two officers stopped on I-75, which was icy at the time, to help motorist who had been involved in an accident. During the stop, the officers car was hit from behind and was pusehd into oncoming traffic. Right then, a tractor-trailer jackknifed, hit another car, and slammed it up against the police cruiser. Amazingly, no one was seriously injured.
