Good morning to you, R. Right now police are telling ABC News that the perliminary belief is that the trucker dozed off right before the crash. 

Kevin Roper, the man who police say slammed a Walmart big rig into Tracy Morgan's limo is sent to meet judge today for the first time after that horrific middle-of-the-night crash Saturday morning on the New Jersy Turnpike. Morgan and three others are still in critical condition right now. The comedian  recovering from a broken leg, femur, nose and several ribs. His * telling ABC News, the 30 Rock star is more responsive. Morgan's driver recounting the frightening moments:" Felt like an explosion, I just remember, the impact and the vehicle going by, seeing a little bit of the Walmart truck go by... We didn't know which way was up, which way was down..." The limo driver kicking the window out to get help," I climbed around and heard Tracy screaming for help but I couldn't reach them and pull them."Police say 35-year-old Roper ran this truck into Morgan's limo bus. Morgan and 6 others on their way back from a stand-up comedy show in Delaware. Sources say the truck swerved to avoid the limo but instead hit it, causing the limo to ose control,  slam into other cars and overturned. Morgan's long-time writing partner James McNair died at the scene. Roper turned himself in after the crash, charged with 1 count of death by auto and 4 counts of assault by auto. Walmart has placed him on a ministrative leave and promise to take full responsibility as the accident was indeed cause by their company's driver. 

And Morgan right now still in critical condition as we said. We're also told he had surgery on his legs Sunday but he could be here for several weeks.
