(ABC News) - A dozing truck driver didn't see traffic slowing in front of his 18-wheeler until it was too late, crashing into the vehicle carrying comedian Tracy Morgan and his entourage, police said today.
Morgan, 45, was in critical condition after the six vehicle crash this morning on the New Jersey Turnpike. Another person on the limo bus was killed and two others were injured, officials said.
"Driver failed to observe slow-moving traffic ahead," New Jersey State Police Sgt. First Class Gregory Williams said. "He observed at the last minute -- just prior to impact -- the limo bus carrying Morgan and his party."
Morgan, who starred in NBC's "30 Rock" and "Saturday Night Live," was taken to Robert Wood Johnson University Hospital in New Brunswick, N.J.

"His family is now with him, and he is receiving excellent care," read a statement from his rep, Lewis Kay. "We don't anticipate much of a change in his condition today."
James McNair, a passenger on board the limo bus with Morgan, was killed in the crash, police said. He was a comedy writer for Morgan.
Morgan's assistant, Jeff Millea, was also in critical condition after he was injured, an official briefed on the investigation said. Two others on board the limo bus were injured in the crash but their conditions hadn't been released as of midday.
The six-vehicle crash happened in the northbound lanes at mile marker 71.5 near New Brunswick about 1 a.m., according to N.J. State Police.
Police believe a truck rear-ended the Mercedes Sprinter bus that Morgan was riding in, causing the crash, an official briefed on the investigation told ABC News.
Morgan was returning from a performance of his "Turn it Funny" tour in Dover, Del., Friday night.
Morgan was scheduled to perform in Charlotte, N.C., tonight but the appearance has been canceled.
Morgan has four children, including a daughterto whom his fiancee Megan Wollover gave birth last July.
