At least 24 people were injured in a crash involving a charter bus and a tractor-trailer on a Virginia interstate on Sunday morning, the authorities said.

There were no fatalities reported, and the injuries ranged from minor to serious, the Virginia State Police said.

The crash took place at about 4:35 a.m. in the eastbound lanes of Interstate 64 near the Blue Ridge Parkway and west of Afton Mountain, about 25 miles west of Charlottesville, the authorities said.

James Proffitt , the driver of the tractor-trailer, lost control, and it overturned across the roadway, the police said. Andrew L. Burruss , who was driving a Silver Lining Tours bus in the same direction, was unable to avoid the tractor-trailer, and the bus struck it and split in half. The bus veered off the side of the highway and came to rest against a guardrail.
