Vehicle Code 27001 prohibits honking a car horn except when reasonably necessary to warn of a safety hazard.  Plaintiff was ticketed for honking her horn in a show of support for demonstrators protesting outside a government official’s office.  Over a strong dissent, this decision holds that section 27001 is a content-neutral restriction on speech (to the extent a car horn is used to convey an idea).  Therefore, the statute is subject to only intermediate scrutiny which it passes because the statute is narrowly focused to further the state’s interest in traffic safety.  The dissent argues that as applied to those who honk their horns to show support for protestors, the statute should be subjected to more rigorous scrutiny.
