A 72-year-old woman is charged following a five car wreck in Roanoke.
It happened Thursday on Williamson Road, just before 4:30.
Investigators say Marjory Watson was turning onto Williamson Road, when her car struck a pickup truck traveling south.
That pickup truck hit two other cars.
That's when one of those cars hit a Roanoke County ambulance.
No one was seriously hurt.
Watson was charged with failure to yield to a highway sign.
