WASHINGTON (AP) — A lottery system for food truck operators in the District of Columbia is about to start.

The new system, which begins Monday, will allot assigned spaces to participating trucks for their exclusive use every weekday. They’ll be able to park in the spaces for four hours.

The assigned spaces are located in spots where trucks tend to congregate to serve the lunch crowd, including Franklin Square, Farragut Square, L’Enfant Plaza and Metro Center.

Trucks that don’t participate can still sell food on district streets, but they have to stay at least 200 feet away from the designated locations and pay parking meter fees.
