(c) Violations of any speed limit fixed pursuant to this section shall be prosecuted in the district court of Wabaunsee county.
(d) For purposes of this section, the governing body of an improvement district specified in subsection (a), shall be deemed a "local authority" for purposes of K.S.A. 8-1432 and 8-1560, and amendments thereto.
