O'Fallon, MO Mobility & Curb Rules: Bike Lane Rules (2026)

060 combines three related driving restrictions in one Section of Chapter 340, Miscellaneous Driving Rules. It first bars a motor vehicle from driving 'within any sidewalk area except on a permanent or temporary driveway,' then turns to bicycle lanes: 'A designated bicycle lane shall not be obstructed by a parked or standing motor vehicle or other stationary object,' meaning a driver cannot leave a car parked in the lane even briefly to load groceries or wait for a passenger. The Section allows a narrow exception: 'A motor vehicle may be driven in a designated bicycle lane only for the purpose of a lawful maneuver to cross the lane or to provide for safe travel,' which covers a driver turning across the lane into a driveway or side street, or briefly using it to avoid a hazard.

Whenever a driver makes that kind of crossing or lawful maneuver, the ordinance requires the driver to 'yield to any bicycle in the lane,' putting the burden on the motorist rather than the cyclist to avoid a conflict. The Section also defines its key term: a 'designated bicycle lane' is a portion of a roadway that the governing body with jurisdiction over that road has marked off, by signing or by pavement striping, for the preferential or exclusive use of bicycles, tying the rule to lanes the City or County has actually striped rather than any shoulder a cyclist happens to use. Chapter 340 does not attach its own fine to this Section, so enforcement runs through the City's Title III traffic-enforcement structure under Chapter 310.
