The truck driver in Chapter 2 represents the way in which the poor help the poor. Tom Joad has been walking home when he comes upon the truck at a roadside diner. A sticker on the windshield reads "No riders," but Tom Joad, walking home from a stint in prison, asks the driver for a ride anyway. When the driver asks Tom if he has seen the sticker, Tom replies, "But sometimes a guy'll be a good guy even if some rich bastard makes him carry a sticker."
The truck driver relents and decides to give Tom a ride. The way Tom asks the driver for a ride divides the world into two—the rich, who make capricious, heartless decisions, and the poor, who are good people who help others. The driver has no choice but to help, as he does not want to be classed with the rich "bastards" who make arbitrary rules. The driver symbolizes the unity of the poor in the face of the unfeeling rich.
