True. Restrictive relative clauses (also called defining relative clauses) are essential to the meaning of the sentence and are not separated by commas. Example: 'The book that I'm reading is interesting.' (Specifies which book). Non-restrictive clauses provide extra information and use commas: 'My brother, who lives in London, is visiting.' (We already know which brother). Removing a restrictive clause changes the meaning, while removing a non-restrictive clause doesn't.
