Unidentified code 20-20 (2001–2005 TLC summonses)
The code 20-20 appears on about 445 TLC summonses written between 2001 and 2005. No TLC chapter 20 existed then, and Title 20 of the City's Administrative Code is consumer-affairs law, not TLC law. The public data gives no description and shows no fine amounts, so what it stood for is not known. It may have been an internal TLC code rather than a rule number.
