According to the NTSB, the left front tire, which was a spare, failed and caused the vehicle to pull hard to the left, crossing into the opposing lane.

“Various aspects of highway safety have been on the NTSB’s most wanted list for a number of years; DUI, distracted driving, youthful driving, tire safety, post crash fire, excess of speed on rural highways, seatbelt use and ejections. We’re not here to speculate on the probable cause at this point, nor are we involved in any criminal aspect of this investigation,” said NTSB Vice Chairman Bruce Landsberg.
