A 43-year-old man suffered a crushed finger and broken ankles during an argument in Pinjarra on Tuesday.
Police were called to Cobb and Co Road just after 10am where they found the injured man.
Mandurah detectives have since charged a Pinjarra man with acts intended to cause grievous bodily harm.
It is alleged the accused man tried to hit the victim with his car after the pair were involved in a dispute at a Moores Road property.
The man narrowly avoided being run over but his left ring finger was partially severed when the car crashed into another vehicle. He also suffered fractures to both ankles and was taken to Peel Health Campus for treatment.
A 59-year-old man has been bailed to appear in the Mandurah Magistrate’s Court on September 9.
