LAYTON — A Layton man was killed Saturday after being ejected from his car on U.S. 89.

The 75-year-old man, whose name was not released Saturday, was traveling north on U.S. 89 when witnesses say he veered off the right side of the road and struck a pole near 750 North, according to Layton Police Lt. Jeff Roderick. The accident occurred just before 9 a.m.

"We don’t know if he had a medical issue or fell asleep," Roderick said. "There were no obvious reasons."

Roderick said the man was pronounced dead at the scene. After colliding with the pole, the man's vehicle, a Buick sedan, caught on fire, which Roderick said makes it difficult to determine whether the man was wearing a seat belt.

The man was the sole occupant of the vehicle, and no other vehicles were involved in the incident. According to Roderick, witnesses on the road said the man was maintaining the speed of surrounding traffic and was not acting erratic prior to veering off the road.
