Season four starts in Los Angeles, under the Hollywood sign, where host and chef Tyler Florence greets the eight teams fighting for their chance to win the grand prize of $50,000 and their own food truck! For the first challenge, the teams must go high class, selling one signature dish in Beverly Hills, Calif., but that dish must be sold for at least $20. The second challenge takes place in San Francisco, where they teams can only sell a NEW signature dish. The team to sell the least amount with their two signature dishes is sent home.
The seven remaining teams head to Portland, Ore., where they're challenged to make the most with what they've got: In their first Speed Bump, they have to go the entire first day without restocking their supplies. On day two, they're given geoduck, which must be the main ingredient in all menu items. After selling $200 with their geoduck menus, they race to a local lumber mill, for a chance to win a reward, which might be enough to save them from this week's elimination.
The six teams remaining enter the mountains of Pocatello, Idaho. For their Speed Bump challenge, they have to rework their dishes to get rid of all starches on their menus. On day two, they're given their Truck Stop challenge: they have to dig up the potatoes they need at a nearby farm, and they'll need a lot, as the potatoes must be the main ingredient in all menu items. After reaching their sales goal, they race to a vista high above the city, where the first three teams to arrive win a reward, and the team who sold the least over the weekend is eliminated.
The five remaining teams meet Tyler at the Crazy Horse Memorial, where they’re given their seed money before heading out to shop in Rapid City, S.D. How will they manage when their follow car is taken during the Speed Bump? On day two, they race to the Wild Idea Buffalo Co., where they find a side of bison that they must butcher for use in all menu items. After selling $1,500 worth of their bison menu, they rush to be one of the first three teams to reach a vista and win a reward, and the next day the losing team is eliminated.
Four teams remain as they enter the Twin Cities — Minneapolis and St. Paul. In honor of the Twin Cities, Tyler gives the teams twin Truck Stops. On day one, to honor the Minnesota state fair, the teams must serve all of their menu items on a stick. On day two, the teams head into St. Paul and must make $500 selling SPAM dishes. The first team to make $500 and meet Tyler at the Peace Officers Memorial at the State Capitol building wins a huge reward, and with only four teams left, this reward could save a team from elimination and send them on to the next city.
Tyler starts the finalists off with a Chicago-style pizza challenge judged by Chicago Mayor Rahm Emanuel. After the mayor chooses the winner, the teams get ready to sell and are given their Speed Bump. The teams must keep a minimum of five dishes on their menu for the rest of the race. On day two, the teams must use another famed Chicago food in all their dishes — polish sausage. Once the teams sell 300 sausages, they race to Mike Ditka's restaurant, where he himself awards the prize and punishment. The winning team will get a five-hour head start to the next city.
With their eyes on the grand prize, the final teams are sent to the east coast in this last leg of The Great Food Truck Race. After a stop in Annapolis, Md., the teams meet Tyler on a Chesapeake Bay island where they haul the crab that will become part of an original crab dish. It may be the most important dish they've ever cooked — as the team with the best crab dish wins a potentially game-changing $1,500 prize. After a surprise elimination, the final two teams are sent to the D.C. suburbs and then into Washington, D.C. where they meet Tyler in front of the U.S. Capitol building and find out who will win $50,000 and ride off in their new food truck.
