Af fatal :: The Daily Herald, Provo Utah: "Phillips had a history of seizures, police learned, but they won't know for sure if Phillips suffered a seizure prior to the accident until extensive medical testing is completed. Drugs and alcohol were not a factor in the accident.

As a commercial vehicle operator, Phillips had to be seizure-free for 12 months. Phillips had been seizure-free for a long enough time that he qualified for the necessary medical card and was cleared to drive. To obtain a class D operator's license, the license used by regular drivers, one must be seizure free for six months."
