Some vehicles work on farms. Others go into space. They may even dive deep below the ocean. No matter where they go, vehicles get the job done. Vehicles on the Job looks at these machines in action. Discover how vehicles help save lives, construct buildings, and make scientific discoveries using science, technology, engineering, and math.
