Section 304.130 - Regulation of vehicular traffic - notice, hearings - approval - publication of notice (first class counties)1. For the purpose of promoting the public safety, health and general welfare and to protect life and property, the county commission in all counties of the first class is empowered to adopt, by order or ordinance, regulations to control vehicular traffic upon the public roads and highways in the unincorporated territory of such counties and to establish reasonable speed regulations in congested areas upon such public roads and highways in the unincorporated territory of such counties. Such regulations shall not be inconsistent with the provisions of the general motor vehicle laws of this state.2. Except as provided in subsection 3 of this section, before the adoption of such regulations, the county commission shall hold at least three public hearings thereon, fifteen days' notice of the time and place of which shall be published in at least two newspapers having a general circulation within the county, and notice of such hearing shall also be posted at least fifteen days in advance thereof in four conspicuous places in the county; provided, however, that any regulations respecting stop signs, signal lights and speed limits on state or federal highways shall be approved by the state highways and transportation commission before the same shall become effective.3. Regulations relating solely to increasing speed limits shall be exempt from the procedural requirements of subsection 2 of this section and shall take effect immediately upon approval of the county commission.4. The regulations adopted shall be codified, printed and distributed for public use; provided, however, that adequate signs displaying the speed limit must be posted along the highways at the points along such highways where such speed limits begin and end.L. 1947 V.
