In Mankato, Minnesota a truck driver put his rig in park and went into a nearby store. His dog was left in the vehicle and somehow got the huge semitrailer moving. The big rig rolled into a tree and parked car. A passerby saw only a Labrador Retriever at the helm and wondered if the dog had actually been the one who crashed the vehicle.
An investigation determined that was indeed what happened.
No one was hurt and no citations were issued.
