The limo bus carrying Morgan lost control and began rotating clockwise and then turned over onto its left side. While it was out of control, the limo bus hit a Buick, which crashed into a Ford F150 pickup truck. The limo also hit another tractor-trailer.
The truck that caused the crash came to rest on the left shoulder after hitting a guardrail.
National Transportation Safety Board spokesman Keith Holloway told ABC News that the NTSB was dispatching a team to investigate the crash along with the N.J. State Police.
The NTSB was going to focus on the "broad issues concerning commercial traffic safety," Holloway said.
Morgan has four children, including a daughter to whom his fiancee Megan Wollover gave birth last July.
