Food trucks are thriving in the District and Arlington County, but are a rare sight in Alexandria because of the city’s restrictive zoning ordinances.

The sale of goods is prohibited on public right-of-ways, roadways and from off-street parking, according to city code, so food trucks are barred from hawking lunches to hungry Alexandria residents and workers, the Alexandria Times reports.

City officials are moving slowly to adopt street vendors in the Old Town area by allowing four local restaurants to set up food carts in Market Square. But the latest effort is just a pilot program, run and financed by the city, and is designed specifically to promote local businesses. Food carts from out of town are still out of luck, as are trucks.
