The “In the truck and out the truck” challenge has become super popular and is going viral on social media. It’s all about showing a dramatic transformation between two moments: one before a significant experience (like a long truck journey) and one after. “In the truck”: This is the “before” photo, where people show themselves at the start of a journey or task—fresh, excited, or maybe even a little nervous. “Out the truck”: This is the “after” photo, where people show how they look or feel after completing the journey—tired, accomplished, or completely transformed by the experience.
