Why on earth would you "always honk at road crews"?
It's illegal:
V C Section 27001 Use of Horns
Use of Horns
27001. (a) The driver of a motor vehicle when reasonably necessary to insure safe operation shall give audible warning with his horn.
(b) The horn shall not otherwise be used, except as a theft alarm system which operates as specified in Article 13 (commencing with Section 28085) of this chapter.
While I suppose they could file a complaint and the police would come out and write you a ticket, I would find that unlikely. Perhaps they are going to create a "Rude Drivers of California" website?
