A run-in between a cow and a semi full of milk sent the truck's driver to the hospital early Tuesday morning.

Just after 3 a.m., a big-rig driver hauling a full load of milk swerved to avoid a cow on Pond Road a quarter mile west of Rowlee Road, according to Kern County Fire Department spokesman Capt. Derek Tisinger. The milk truck still hit the cow, then rolled.

The front of the cab was compressed and twisted in the crash, pinning the driver's legs, Tisinger said. A passerby called for help and the Kern County Fire Department responded, along with the department's urban search and rescue team.

The unidentified driver was extracted after about three and a half hours and airlifted to Kern Medical Center with major injuries, according to firefighters.

The bovine died and the milk ended up spilled in a field.
