Two people were hurt after a pickup and semi crashed on Highway 151 near Anamosa.
Linn County sheriff's deputies believe the semi slammed on its brakes to avoid hitting a motorcycle Tuesday afternoon, causing a pickup to rear-end it.
The driver and a child in the pickup truck were injured in the crash. The sheriff's office says the driver was taken to the hospital in Anamosa. The child was airlifted to the University of Iowa Hospitals and Clinics.
Their conditions are unknown.
