O'Fallon does not run a nightly curfew on street parking, but it bans leaving any vehicle on a roadway for longer than 48 consecutive hours. The limit applies City-wide under Chapter 355 and exists independently of any posted signage.

Full Breakdown
100 states flatly that no person shall park a vehicle upon any roadway for a period of time longer than 48 hours. Unlike some of the City's other stopping and standing rules, this provision does not depend on the City Traffic Engineer posting signs first; the 48-hour cap applies automatically to every street in O'Fallon. The section traces back to Ord. No. 247, adopted in 1962, and has carried the same 48-hour figure through the 1978 Code and the 2007 and 2008 recodifications. 010's general stopping and standing bans.
Because the 48-hour rule is roadway-wide rather than sign-dependent, a resident cannot avoid it by choosing an unsigned block; a vehicle that has not moved from the same stretch of street for more than two days is in violation regardless of location. The rule is distinct from Chapter 385's winter weather parking prohibition, which triggers automatically with snow or ice accumulation and is unrelated to how long a vehicle has sat in place.
Violations & Fines
Violating the 48-hour limit is punished under the general penalty in § 100.010: a fine of up to $500, up to three months in the St. Charles County Jail, or both. Vehicles left in place beyond the limit are also subject to towing under the City's abandoned/inoperable vehicle provisions enforced by the O'Fallon Police Department.
