Kin Yiu Cheung faces up to 40 years in prison, after a judge convicted Cheung on four counts of involuntary manslaughter in connection with a May 2011 crash on Interstate 95, about 30 miles north of Richmond.
Cheung was driving the Sky Express Bus from Greensboro, N.C. to New York, when he swerved off the road, hit an embankment and overturned. Passengers on the bus say Cheung was driving erratically before the crash.
A state trooper testified that Cheung nodded when asked whether he'd fallen asleep behind the wheel.
A Caroline County Circuit judge told Cheung that his conduct was "so gross and wanton," that he had no choice but to find him guilty of the four counts.
Cheung faces up to 40 years in prison, and is scheduled for sentencing on Jan. 23.
