That's according to the new report just released from the National Transportation and Safety Board.
The June 7th crash on the New Jersey Turnpike badly injured the comedian and killed one of his friends.
Now, the NTSB is releasing new images of the extent of the damage to Morgan's limo.
According to the report, the truck driver, Kevin Roper, was speeding about 60 seconds before the crash, which also caused significant damage to the truck.
Investigators are now looking at how long Roper was awake and driving when he reported to work the day before the crash.
Roper is charged with death by auto and four counts of assault.
