The driver of a bus that overturned on a Virginia highway told State Police he was going about 70 mph (113 kph) when he "turned suddenly" and tried to take an exit ramp before the deadly crash.

Citing an affidavit for a search warrant, the Richmond Times-Dispatch reports that 40-year-old Yui Man Chow made the statement to a trooper. The New York resident is charged with two counts of involuntary manslaughter. He appeared in court Monday.

Police say the bus was traveling from Florida to New York with 57 people aboard when it overturned last week. Two people were killed and dozens were injured.

The crash was the ninth at the exit since 2014. Officials are investigating if any occurred because signs had confused drivers.

Chow's attorney Adam Jurach declined to comment.
