ET Investigates Tracy Morgan's Horrific Car Crash

Following the car crash that left Tracy Morgan in critical condition, ET's Rocsi Diaz is on the ground looking into the accident and how it could have been worse.

According to Sgt. Gregory Williams of New Jersey State Police who spoke to ET, the 45-year-old comedian was a passenger in a limo bus when the accident occurred in Cranbury Township at 1 a.m. on the turnpike. In a preliminary assessment, Williams said it appears that a tractor trailer rear-ended the limo, but police don't believe drugs or alcohol were involved. Seven people were in the limo bus, and the two people in the front seat were fine. The five passengers in the backseat (including Morgan) were rushed to the hospital, but one of those five was killed.

Rocsi spoke to Richard Fertig, president and founder of luxury transportation company Brilliant, who deals with vehicles that are similar to the one that Tracy was in at the time of the crash. Richard explained that the accident could have had an even darker turnout.

"Given the size of this vehicle and the weight, this would absorb the blow of a semi-truck much more than say a stretch or a sedan," said Richard. "If you take a look at the size of this trunk, which is enormous, this may have acted as a barrier to that blow."

It is important to note that Tracy was not in a Brilliant vehicle at the time of the crash.

While the vehicles are equipped with seatbelts, it has yet to be determined if Tracy was wearing one. The stars that we talked to gave the impression that most passengers don't wear a seatbelt on a bus like the one Tracy was in.

"The first thing I thought of was, 'When you're in a limo, people tend not to wear seatbelts, and it's easy to get hurt,'" said Fran Drescher.

According to Tracy's rep, the actor will remain in the hospital for several weeks.

According to The New York Times, the Walmart driver charged in the crash hadn't slept for more than 24 hours before the accident.

The truck driver, Kevin Roper, 35, has been charged with one count of death by auto and several counts of assault by auto, NYT reports.
