The incident happened Saturday evening.
A female driver told Evansville Police she was driving west bound with her 11-month-old child when she passed Clifford Johns.
Johns became upset and followed her, pulling his truck beside her car on Diamond and Fulton Avenue.
She says the two began to argue about her allegedly cutting Johns off.
She says Johns pulled out pepper spray and sprayed it into her car, hitting her face and arms.
Johns told EPD the woman tried to make contact with his truck several times and that he sprayed her out of fear.
Johns was arrested and has since been released on bond.
