Pre-1992 TLC rule (text not online)
This code comes from the TLC's numbering used before mid-1992 (2 charges in OATH's data, violation dates May 20, 1992 to May 22, 1992). The text of that rule is not available online, so we can't say exactly what it covered. There are too few cases to tell whether it applied to drivers or to vehicle owners. The written description on your summons is the best guide.
