well this thread has gone all over the place, but lets get to basics.. as
sign people we need to understand how the 1st ammendment affects our work. If the agency (a government or government funded one) uses the CONTENT of the message to restrict the message, then they are violating free speech, even commercial free speech, which is protected.
Now if they should choose to outlaw all commercial vehicles in a neighborhood, or restrict their use and parking during some time period, based solely on DMV registration records/licensing categories, then that is fine, as it is not related to the art or message on the vehicle. But that code cannot use the VISUAL CONTENT of the graphics as the means to determine whether you can drive it there.
you need to get the agency to say IN WRITING, that they made the determination based on your wrap. Then hire an attorney (
SignLawyer.com, lawyer, signlaw, lawyers, law, California, Electric, Sign , Association, Signs, Electrical, neon, sign, powerline, logo, sign users, members, Jeff, Aran, Sacramento) or get SGIA and OAAA to help you find counsel. There is already case law from SCOTUS on this from 2015 - Reed v Gilbert. it deals with signage and free speech. Using content as a test requires the code meet "strict scrutiny", a legal term meaning there is a compelling reason for govt to restrict your speech rights, and that there isnt any lesser means to deal with it. Any
sign code that uses the CONTENT of a
sign is most likely in fault and this has been well publicized in national magazines. The issue of graphics on vehicles is a point that
sign law experts have discussed as the next likely SCOTUS case given Reed v Gilbert. Is the ford logo an ad for Ford, or the FEDEX logo an ad or just identification? and what of a political group's tour bus in front of the senator's house?
Municipal governments may not
"restrict expression because of its message, its ideas, its subject matter, or its content" - P
olice Dept. of Chicago v. Mosley, 408 U.S. 92, 95 (1972).
I would make sure you DO NOT HAVE any codes covenants or restrictions (CCR's) on your property title. CCR's from property sales affect your rights. But in any case, making the distinction between commercial and not based solely on the graphics is not CONTENT NEUTRAL that Reed v Gilbert setup. SCOTUS-
"restrictions in the Sign Code that apply to any given sign [depend] entirely on the communicative content of the sign".
