My sense is that young truckers today, being a more diverse audience than they were in the past, also have more diverse musical tastes. Many also prefer to listen to talk radio. The SIRIUS radio network, for instance, hosts several popular trucker-oriented shows on its Road Dog Network. The old all-night AM radio shows that targeted truckers with country songs and Peterbilt advertisements in the 1960’s and 1970’s are largely a thing of the past.
