provided in this section.
(b) The Indiana department of transportation may conduct an
investigation of a bridge or other elevated structure constituting a
part of a highway. If the Indiana department of transportation finds
that the structure cannot with safety to the structure withstand
vehicles traveling at the speed otherwise permissible under this
chapter, the Indiana department of transportation shall determine and
declare the maximum speed of vehicles that the structure can
withstand. The Indiana department of transportation shall cause or
permit suitable signs stating the maximum speed to be erected and
maintained at a distance of one hundred (100) feet or as near as
practicable before each end of the structure.
(c) Upon the trial of a person charged with a violation of this
section, proof of the determination of the maximum speed by the
Indiana department of transportation and the existence of signs
erected under subsection (b) constitutes conclusive evidence of the
maximum speed that can be maintained with safety to the bridge or
structure.
