The album marked a significant musical shift for Dylan, who embraced more pop-rock arrangements, collaborated with a large group of backing vocalists, and decisively moved towards black music.
From the title itself, Street Legal is a statement of intent: "street illegal" referred in the fifties to gambling machines, but "street legal," in street language, meant a "cool guy," a "hip," or a "straight shooter."
Moreover, "Street legal" also refers to modified car engines that, after passing safety inspections, become legitimate and legal. (source: wiki)
