A mobile billboard is a device used for advertising on the side of a truck or trailer that is typically mobile. Mobile billboards are a form of out-of-home advertising (OOH); radio, static billboards, and mall/airport advertising fall into this same category. Using a mobile billboard for advertising is an advertising niche called mobile outdoor advertising.
