They say the girl's mother quickly retrieved the 9-month-old off the road on April 1, but the girl suffered cuts to her mouth, stomach, sides and legs.
Prosecutors say 23-year-old Erik Johnston was driving his car when he became angry, pulled over, grabbed his daughter by the arm and threw her. He faces charges of domestic battery, child endangerment and false imprisonment.
A person who partially saw the incident called the sheriff's office.
It could not be immediately determined whether Johnston had a lawyer. A message left at the prosecutor's office seeking to find out was not immediately returned Tuesday.
