On 29 November 2017, a driver with a private car transport company sued Herzi after receiving a series of SMS insults, including "dirty Arab", for events occurring during a trip. She pleaded not guilty as she claimed she used 'dirty Arab' as a tone of ironic meaning, however she has been known for acting hostile against Arabs. On 13 November 2019, she was found guilty of racial insults by the Paris Court of Appeal.
