§ 545.3561. AUTHORITY OF MUNICIPALITY OR COUNTY TO TEMPORARILY LOWER SPEED LIMIT AT VEHICULAR COLLISION RECONSTRUCTION SITE.
Status: in_force

(a) The governing body of a municipality by ordinance may give a designated official with transportation engineering experience establishing speed limits discretion to temporarily lower a prima facie speed limit for a highway or part of a highway in the municipality, including a highway of the state highway system, at the site of an investigation using vehicular collision reconstruction.

(b) A county commissioners court by order may give a designated official with transportation engineering experience establishing speed limits discretion to temporarily lower prima facie speed limits for a county road or highway outside the boundaries of a municipality at the site of an investigation using vehicular collision reconstruction. The authority granted under this subsection does not include a road or highway in the state highway system.

(c) The Texas Department of Transportation shall develop safety guidelines for the use of vehicular collision reconstruction in investigations. A municipality, county, or designated official shall comply with the guidelines.

(d) A designated official may temporarily lower prima facie speed limits without the approval of or permission from the Texas Department of Transportation. A designated official who intends to temporarily lower a prima facie speed limit at the site of an investigation using vehicular collision reconstruction shall, at least 48 hours before temporary speed limit signs are posted for the vehicular collision reconstruction site, provide to the Texas Department of Transportation notice that includes:

(1) the date and time of the collision reconstruction;

(2) the location of the collision reconstruction site;

(3) the entities involved at the site;

(4) the general size of the area affected by the site; and

(5) an estimate of how long the site will be used for the collision reconstruction.

(e) A temporary speed limit established under this section:

(1) is a prima facie prudent and reasonable speed limit enforceable in the same manner as other prima facie speed limits established under other provisions of this subchapter; and

(2) supersedes any other established speed limit that would permit a person to operate a motor vehicle at a higher rate of speed.

(f) A designated official who temporarily lowers a speed limit shall:

(1) place and maintain at the vehicular collision reconstruction site temporary speed limit signs that conform to the manual and specifications adopted under Section 544.001;

(2) temporarily conceal all other signs on the highway segment affected by the vehicular collision reconstruction site that give notice of a speed limit that would permit a person to operate a motor vehicle at a higher rate of speed; and

(3) remove all temporary speed limit signs placed under Subdivision (1) and concealments of other signs placed under Subdivision (2) when the official finds that the vehicular collision reconstruction is complete and all equipment is removed from the vehicular collision reconstruction site.

(g) A temporary speed limit established under this section is effective when a designated official places temporary speed limit signs and conceals other signs that would permit a person to operate a motor vehicle at a higher rate of speed as required under Subsection (f).

(h) A temporary speed limit established under this section is effective until the designated official under Subsection (a) or (b):

(1) finds that the vehicular collision reconstruction is complete; and

(2) removes all temporary signs, concealments, and equipment used at the vehicular collision reconstruction site.

(i) If a designated official does not comply with the requirements of Subsection (f)(3) for a vehicular collision reconstruction on a state highway associated with the reconstruction, the Texas Department of Transportation may remove signs and concealments.
