Oceanside, a coastal California city near San Diego, recently passed a motion to issue a request for proposals to solicit advertising on city vehicles. 

City vehicles except police vehicles, fire apparatus, and ambulances could potentially support advertising under this proposal, according to a report from the city manager's office. The revenue received from these ads would be allocated to support youth, senior, homeless, and environmental programs as decided by the city manager. 

Although the exact amount of revenue can't be determined until proposals are received, the city manager's report estimates $150,000 in annual revenue if the city fits 100 vehicles with advertising.

the city would have approval on all advertising, and plans to ban any advertising related to alcohol, tobacco, drugs, and entertainment, according to the San Diego Union-Tribune.

The issue came up after vendors began approaching the city about advertising options. Oceanside had a similar agreement with an advertiser between 1997 and 2002, which permitted advertising on the tailgates of city trucks.
