Tracy Morgan -- Truck Driver Wants Criminal Charges Dismissed

The Walmart truck driver who crashed into Tracy Morgan's limo wants the criminal charges against him dismissed, because he says the superstore has made it impossible for him to get a fair trial.

Kevin Roper claims in legal docs there have been a flood of admissions over the accident since he was criminally charged back in June, 2014 ... including Walmart issuing a press release saying it was responsible for the accident.

Roper says between Walmart, the NTSB and Morgan's lawyer, the media has been saturated with stories already convicting him, thus making a fair trial impossible.
