A rep for Tracy Morgan released a new positive report about the status of the comedian's health.

According to publicist Lewis Kay, the 45-year-old actor is showing great improvement after surviving a deadly six-vehicle accident on the New Jersey Turnpike on June 7.

"Happy to pass along that Tracy has been upgraded to fair condition, which is a great improvement," Kay said, according to CNN. "His personality is certainly starting to come back as well."

The comic was badly injured when a Wal-Mart truck slammed into a limo bus carrying Morgan and four others. The collision killed Morgan's mentor, comedian James McNair, aka Uncle Jimmy Mack, while injuring the other passengers, including his assistant, Jeffrey Millea, who was seriously injured.

The former "Saturday Night Live" star was hospitalized with broken ribs, a broken nose, a broken femur and a broken leg. He had been in critical but stable condition.

Kay added that Millea has also improved to fair condition.

The Wal-Mart truck driver, Kevin Roper, turned himself in to police the night of the crash and has pleaded not guilty to vehicular homicide and assault by auto charges. In a criminal complaint, police said Roper hadn't slept for more than 24 hours before the accident and that he swerved to avoid slowed traffic and plowed into "30 Rock" star's limo, SFGate.com reported.

In the wake of the crash,, New Jersey Senators Cory Booker and Robert Menendez are planning to block a measure that would roll back safety regulations on the trucking industry.

The officials are pushing legislation to repeal an amendment approved last month by the Senate Appropriations Committee that would roll back regulations on the length of driver workday.

"A new effort has arisen in the U.S. Senate to roll back protections that limit how many hours a week truck drivers can work. We should be looking to strengthen protections, not undermine them," Menendez said, according to CBS New York. "We wouldn't consider rolling back FDA-approved safety regulations during an E. coli outbreak."
