Jefferson County, MO Parking Rules: Street Parking Limits (2026)

Jefferson County's Traffic Code, enforced by the Sheriff's Department outside cities and towns, sets the ground rules for parking along county roads. 010 bars anyone from stopping, standing, or parking within eighteen inches of the traveled portion of any county road, a narrow buffer that keeps vehicles off the shoulder edge on rural two-lane roads. 030 goes further for private roads dedicated to public use and alleyways: parking cannot leave less than ten feet of roadway width open for vehicles to pass, and no vehicle may be stopped, stood, or parked so as to block the entrance to any abutting property, the county's direct ban on blocking driveways.

040 unless the County Council has adopted an ordinance allowing it and posted signs at the location. 050 layers on a list of specific no-stop zones, including sidewalks, intersections, crosswalks, within fifteen feet of a fire hydrant, within thirty feet of an intersection approach, and within fifty feet of a railroad crossing; the Department of Public Works can extend several of those distances up to one hundred feet where signs are posted. 060 requires the officer to record the plate and affix a written notice giving the driver five days to respond, with a copy forwarded to the Violations Bureau. 090 that carry time limits, location restrictions, and proof of liability insurance.
