WASHINGTON (AP) — Investigators say they are focusing on driver fatigue, truck safety and seatbelt use in a highway accident last year that severely injured comedian Tracy Morgan and killed another comedian.

Chris Hart, chairman of the National Transportation Safety Board, speaking at a meeting to determine the cause of the accident, that the board will “ask what safeguards operators can adopt to address driver fatigue,” as well as highway work zone hazards.

Hart also says Tuesday the limousine-van Morgan and several other entertainers and friends were riding in had been customized, leaving the passengers no way to escape the vehicle after it was struck from behind by a Wal-Mart truck on June 7, 2014. The accident happened as the limousine slowed down for construction on the New Jersey Turnpike.

Investigators have said the truck driver had been awake for 28 hours and failed to slow down due to fatigue.
