BOWLING GREEN, VA (AP) — A trial has been postponed for the driver of an interstate bus that crashed in Virginia in May, killing four passengers and injuring dozens more.

Caroline County Commonwealth’s Attorney Tony Spencer says a hearing in the case of Kin Yiu Cheung of New York will be held March 7. Cheung was scheduled to go on trial Thursday on four felony counts of involuntary manslaughter.

Court records show Cheung admitted to police that he fell asleep at the wheel when the low-fare Sky Express bus from Greensboro, N.C., to New York City swerved off Interstate 95 about 30 miles north of Richmond, hit an embankment and overturned with 60 people aboard May 31.

He faces up to 10 years in prison for each count if convicted.

Cheung has pleaded not guilty.
