Honk If You Love Incitement Law:

From Goedert v. City of Ferndale, 2008 WL 928315 (E.D. Mich.), a case decided last year, but just posted on Westlaw — a fun fact pattern, and one that rarely leads to First Amendment litigation. I offer the opinion as an interesting bit of First Amendment analysis for First Amendment buffs; I leave it to you to figure out whether and to what extent you think this is right.

Plaintiffs challenge the City of Ferndale's suppression of automobile horns as a form of expression. The City has enforced an ordinance to prohibit the display of signs asking motorists to "honk" their horns to express their support for the demonstrators, and prohibiting motorists from honking their horns for that purpose. Plaintiffs allege that the City's prohibition violates the First Amendment's guarantee of freedom of speech.

In support for peace in Iraq, Plaintiffs Nancy Goedert, Victor Kittila, and Jim Grimm have participated in a Vigil on the corner of Woodward Avenue and Nine Mile Road in the City of Ferndale on Monday evenings. The Vigil has been conducted at that location for nearly five years. At one point, Vigil participants began to display signs stating "Honk for Peace" and later "Honk if You Want Bush Out." Over the years, hundreds of motorists have communicated their agreement with the demonstrators by honking their horns as they passed by the Vigil. Plaintiffs characterize the honks in support of the Vigil as citizens electing to join in a conversation among the citizens on perhaps the most pressing public issue of the day.

For the first three and a half years of the Vigil, there were no traffic problems or accidents associated with the Vigil. Ferndale changed its approach towards the Vigil in June of 2006, when Police Captain Timothy Collins witnessed the same intersection crowded with health care reform demonstrators. Demonstrators were on every corner of the intersection, the sidewalks, and alongside the median. A concerned Captain Collins felt that the demonstrators were unruly and were causing a safety hazard by leaning into traffic with their signs, and he felt that the honking of vehicle horns was a distraction that could lead to safety problems. The next morning, Captain Collins discovered a Michigan Statute, M.C.L. 257.706(a), which provides that "the driver of a motor vehicle shall when reasonably necessary to insure safe operation give audible warning with his horn but shall not otherwise use the horn when upon a highway." This "Honk Statute," like the rest of Michigan's Motor Vehicle Code, has been incorporated into Ferndale's ordinances....

Captain Collins then contacted the City Attorney's Office to ascertain whether both statutes could be enforced against the demonstrators. The City Attorney's Office approved the enforcement of the statutes against those at the Vigil, and the decision to apply them to ban the use of the word "honk" on any signs at the Vigil. After receiving a warning from the Ferndale police department, Plaintiff Kittila revised his sign to read "Ferndale Cops Say: Don't HONK if you want BUSH OUT." Plaintiff Nancy Goedert was holding a similar sign that read "POLICE SAY DON'T HONK for PEACE." On July 3, 2006 Plaintiff Kittila was arrested for holding his sign, while two weeks later, on July 17, 2007 Nancy Goebert was ticketed by the City for violation of the "Honk Statute ." On October 9, 2006, Officer Carroll stopped and ticketed a motorist who honked in support of the Vigil, Plaintiff Brian Price....
