The Dixie Chicks's tour bus was rear-ended early Thursday while parked along a highway on the outskirts of San Antonio, Texas, police there tell the Associated Press. Emily Robison, the only Chick onboard at the time, was not injured.
The Chicks, who also include Natalie Maines and Martie Maguire, played a Houston concert Wednesday night and a San Antonio gig Tuesday as part of their current international the Top of the World Tour.
According to the police report covering the accident, the tour bus pulled over on an overpass at 3:30 a.m. after being struck with an unknown object. Police say the parked bus was partially blocking a traffic lane.
As the driver, Ross Ellis, inspected the bus for possible damage, a pickup truck driven by Larry Cox of Corpus Christi struck the back of the vehicle. Police said Cox received treatment at a hospital for a cut on his right arm.
Cox also told police that his answering his cell phone caused him to briefly take his eyes off the road as he was approaching the parked bus, and he did not see it in time.
In their report, police said Ellis had properly activated the emergency flashers on the bus but was still partly to blame for the incident because the bus was parked in the roadway.
The Chicks are due to perform in Little Rock, Ark., Friday night.
