Police arrested Tahir Malik, 49, Friday after he allegedly offered his services to a 65-year-old man, whose name was not reported, the Chicago Tribune reported Saturday.
The older man told police Malik said he would "help him with traffic offenses" in exchange for $1,400 in cash.
Malik previously served one year of a two-year prison sentence for another impersonation of a lawyer charge, the Illinois Department of Corrections said. He was paroled in December 2011.
Police said Malik, who manages an auto repair shop, hasn't spent a single day in law school.
