At least nine firefighters were injured Monday in a crash in Palmdale.
Authorities are investigating to determine what caused the crash of the U.S. Forest Service truck near Angeles National Forest.
"Who knows what happened out here," said Nathan Judy, of the U.S. Forest Service. "It could have been an animal in the road, it could have been anything."
The crash occurred at about 9:30 p.m. Monday on Mount Emma Road east of Cheseboro Road, California Highway Patrol Officer Krystal Carter said. The truck tumbled about 15 feet down an embankment and landed on its side.
Los Angeles County firefighters extricated three firefighters from the truck. They were transported by ground ambulance and helicopters to hospitals, said Los Angeles County Fire dispatcher Ed Pickett.
The Associated Press reported that authorities said the driver of the U.S. Forest Service truck swerved to avoid a dog. The dog was not injured, according to the AP report.
Eastbound Mount Emma Road was closed at Cheseboro Road while the CHP investigated the crash, Carter said.
