National Food Truck Day is observed in the United States every last Friday of June. Celebrated since 2016, this holiday encourages people to support local food trucks by purchasing meals from them. The origins of food trucks in the U.S. trace back to the mid-19th century, with early versions like chuckwagons and lunch wagons. Today, food trucks offer a diverse array of foods, including hot dogs, tacos, ice cream, and sushi, making them a popular choice for affordable meals. The holiday was initiated by Roaming Hunger, a California-based food truck booking service, with the aim of promoting local food truck businesses. Participants are encouraged to share their food experiences on social media using the hashtags #NationalFoodTruckDay and #FoodTruckDay.
