The Traction control flashed immediately before the wreck so my assumption is there was a traction lock malfunction. The road was wet due to rain. My husband was driving 55 mph when the truck's steering locked and we ended up in the right side ditch where we hit an electric power pole. My husband had several fractured ribs. My right lower arm was broken, required surgery and a week long stay in the hospital. They put a rod with screws into my arm. The truck was totally destroyed according to our insurance company.
