On Wednesday the Chicago City Council approved an ordinance that allows food truck operators to cook onboard.
Under the ordinance, food trucks can't park closer than 200 feet from a restaurant entrance unless they're in designated food-truck parking spots. Food trucks also will be required to have GPS to track their movements.
Chicago is known for high-end restaurants but has lagged behind other cities when it comes to the food truck craze.
Mayor Rahm Emanuel and the city's aldermen say the ordinance approved Wednesday is a good first step to expand the industry.
The trucks have been able to operate in Chicago, but chefs couldn't cook and prepare food in their vehicles.
