Mobile vending is loosely defined as selling food out of any portable vehicle, including trucks, carts, trailers, roadside kiosks, and stands. Mobile vendors are common in almost every community, whether as taco trucks in Los Angeles, hot dog carts in New York City, fruit stands on rural roadsides, or ice cream trucks on neighborhood streets. In underserved neighborhoods unlikely to attract a large grocery store, mobile vending can be a source of healthy food options.
