“Advertising” and “advertised” as used in this Section shall be deemed to include any display of the name of a business, the telephone number of the business, or the address of a business or a depiction of the function of the business.

It shall be unlawful to attach any sign to or upon any vehicle, trailer, skid or similar mobile structure where the primary use is to provide a base for the sign itself and where the vehicle is allowed to remain parked along a right-of-way in the same location or in the same vicinity at frequent or extended periods of time exceeding 8 hours.

Vehicles whose primary use is the regular delivery of goods or services may have such goods and services advertised upon the vehicle, provided that the owner can demonstrate, through a log or other documentation made contemporaneously with the vehicle usage, that the primary use of the vehicle is the regular delivery of goods or services.

Signs shall be permanently attached to the vehicle in a professional manner by being painted, adhered, bolted, screwed or magnetically affixed. No sign or advertising structure shall be erected or attached to any vehicle except for those signs which are painted directly or mounted flush to the surface or mounted directly on the roof of the vehicle. No roof-mounted signs shall project more than 12 inches above the roof of the vehicle or the bed of a pickup truck.

Banners or signs made of cloth or other light materials, secured with rubber, rope, string, tape or other similar adhesives shall be prohibited for vehicular advertising.

Vehicle advertising affixed to a vehicle which has been altered for purposes of circumventing these regulations shall be prohibited.

Vehicles that are inoperable, that are not properly licensed and/or are currently not registered shall not be used, parked or stored in a manner to provide advertising.

Vehicles displaying advertising shall not be parked off the site of the business primarily for the purpose of advertising.

Vehicles and trailers displaying advertising shall not be parked on property other than that of the advertised business unless such vehicle or trailer is being used by owners or employees of such business at the location where such vehicle is parked. The absence of any owner or employee of the advertised business at the site where the vehicle or trailer is parked shall be prima facie evidence that it is not being used by such owners or employees. It shall be an affirmative defense to this subsection if it is established that the vehicle was parked on property for the purpose of repair by a business operating at such location.
