Full Breakdown
Rather than write its own stopping-and-parking code, St. Charles County adopted the state's Model Traffic Ordinance (RSMo. Chapter 300) by reference for every unincorporated road, county highway, and street: the same body of law that bars parking that blocks driveways, blocks intersections, or faces the wrong way against traffic. The County Police Department enforces it, and violations are misdemeanors under Section 300.001(E). Layered on top, the County Council designates its own no-parking zones street-by-street (Schedule III, Table III-A) and bans parking within ten feet of any mailbox (Section 307.200).
Violations & Fines
Violating the adopted Model Traffic Ordinance is a misdemeanor punishable by up to a $1,000 fine, up to one year in County Jail, or both; each day counts as a separate offense.
