A driver apparently lost control of an armored car on Highway 101 Thursday morning in Ukiah and crashed down an embankment.
The Garda truck was headed north when the large vehicle hit the center divide, shot across the highway and became airborne, emergency officials said.
It landed on its wheels down in an embankment alongside the highway.
No injuries were reported.
What caused the driver to crash remained under investigation Friday. Further information was not available from the CHP.
