Luella Bates began working for the Four Wheel Drive Auto Co. During World War I, she worked as a test driver traveling throughout the state of Wisconsin in a Model B truck. After the war, when the company let the majority of the women go, Luella remained as a demonstrator and driver. In January 1920, Luella traveled to New York City where she attended the New York Auto Show. During her stay she became the first woman truck driver to receive a drivers license in New York. In 1920, Four Wheel Drive sent Bates on three transcontinental tours throughout the United States to introduce the idea that the truck was so easy to steer a women could drive it.
