Speed limits greater or lesser than reasonable; alteration by local authority; engineering and traffic investigations; validity of speed limits; conditions
Sec. 6. (a) Except as provided in subsections (e) and (f), whenever a local authority in the authority's jurisdiction determines that the maximum speed permitted under this chapter is greater or less than reasonable and safe under the conditions found to exist on a highway or part of a highway, the local authority may determine and declare a reasonable and safe maximum limit on the highway. The maximum limit declared under this section may do any of the following:
(1) Decrease the limit within urban districts, but not to less than twenty (20) miles per hour.
(2) Increase the limit within an urban district, but not to more than fifty-five (55) miles per hour during daytime and fifty (50) miles per hour during nighttime.

(b) Except as provided in subsection (f), a local authority in the authority's jurisdiction shall determine by an engineering and traffic

investigation the proper maximum speed for all local streets and shall declare a reasonable and safe maximum speed permitted under this chapter for an urban district. However, an engineering and traffic study is not required to be performed for the local streets in an urban district under this subsection if the local authority determines that the proper maximum speed in the urban district is not less than twenty-five (25) miles per hour.
(c) An altered limit established under this section is effective at all times or during hours of darkness or at other times as may be determined when appropriate signs giving notice of the altered limit are erected on the street or highway.
(d) Except as provided in this subsection, a local authority may not alter a speed limit on a highway or extension of a highway in the state highway system.

(1) The limit is not less than twenty (20) miles per hour.
(2) The limit is imposed only in the immediate vicinity of the school.
(3) Children are present.
(4) The speed zone is properly signed. After June 30, 2011, there must be:

(ii) as near as practical to the point where the reduced speed zone begins;
indicating the reduced speed limit; and
(B) a sign located at the end of the reduced speed zone indicating:
(i) the speed limit for the section of highway that follows; or

(3) The speed zone is properly signed.
(f) A city, town, or county may establish speed limits on a street or highway upon which a school is located if the street or highway is under the jurisdiction of the city, town, or county, respectively. However, a speed limit established under this subsection is valid only if the following conditions exist: (1) The limit is not less than:
(A) twenty (20) miles per hour within an urban district; and
(B) thirty (30) miles per hour outside an urban district.
(2) The limit is imposed only in the immediate vicinity of the school.
(3) Children are present.
(4) The speed zone is properly signed. After:
(A) June 30, 2011, there must be:
(i) a sign located where the reduced speed zone begins or as near as practical to the point where the reduced speed zone begins indicating the reduced speed limit; and
(ii) a sign located at the end of the reduced speed zone indicating the end of the reduced speed zone; and

IC 9-21-5-8
Minimum speed limits
Sec. 8. Whenever the Indiana department of transportation within the department's jurisdiction or a local authority within the authority's jurisdiction determines, based on an engineering and traffic investigation, that slow speeds on a part of a highway consistently impede the normal and reasonable movement of traffic, the Indiana department of transportation or local authority may determine and declare a minimum speed limit below which a person may not drive a vehicle except when necessary for safe operation or in compliance with law. A limit determined under this subsection and declared by appropriate resolution, regulation, or ordinance becomes effective when appropriate sign or signals giving notice of the limit of speed are erected along the affected part of a highway.

Sec. 10. (a) A person may not drive a vehicle over a bridge or other elevated structure constituting a part of a highway at a speed that is greater than the maximum speed that can be maintained with safety to the bridge or structure, when the structure is signposted as 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.
As added by P.L.2-1991, SEC.9.

IC 9-21-5-11
Temporary maximum speed limits; worksite speed limits; penalties
Sec. 11. (a) Subject to subsection (b), the Indiana department of transportation, the Indiana finance authority, or a local authority may establish temporary maximum speed limits in their respective jurisdictions and in the vicinity of a worksite without conducting an engineering study and investigation required under this article. The establishing authority shall post signs notifying the traveling public of the temporary maximum speed limits established under this section. (b) Worksite speed limits set under this section must be at least ten (10) miles per hour below the maximum established speed limit.
(c) A worksite speed limit set under this section may be enforced only if:
(1) workers are present in the immediate vicinity of the worksite; or
(2) if workers are not present in the immediate vicinity of the worksite, the establishing authority determines that the safety of the traveling public requires enforcement of the worksite speed limit.
(d) Notwithstanding IC 34-28-5-4(b), a judgment for the infraction of violating a speed limit set under this section must be entered as follows:
(1) If the person has not previously committed the infraction of violating a speed limit set under this section, a judgment of at least three hundred dollars ($300).

The differing limit is effective when appropriate signs giving notice of the limit are erected.
(b) A maximum speed limit under this section may be declared to be effective at all times or at times indicated on the signs. Differing limits may be established for different times of day, different types of vehicles, varying weather conditions, and other factors bearing on safe speeds.
