             12          This bill:
             13          .    authorizes the Department of Transportation to establish a posted speed limit that

             37          Section 1. Section 41-6a-602 is amended to read:
             38           41-6a-602. Speed limits established on state highways.
             39          (1) (a) The Department of Transportation shall determine the reasonable and safe speed
             40      limit for each highway or section of highway under its jurisdiction.
             41          (b) For each highway or section of highway, each speed limit shall be based on a traffic
             42      engineering and safety study consistent with the requirements and recommendations in the
             43      most current version of the "Manual on Uniform Traffic Control Devices."
             44          (c) The traffic engineering and safety studies shall include:
             45          (i) the design speed;
             46          (ii) prevailing vehicle speeds;
             47          (iii) accident history;
             48          (iv) highway, traffic, and roadside conditions; and
             49          (v) other highway safety factors.
             50          (2) In addition to the provisions of Subsection (1), the Department of Transportation
             51      may establish different speed limits on a highway or section of highway based on:
             52          (a) time of day;
             53          (b) highway construction;
             54          (c) type of vehicle;
             55          (d) weather conditions; and
             56          (e) other highway safety factors.
             57          (3) (a) Except as provided in Subsection (3)(b) and (c), a posted speed limit may not
             58      exceed 65 miles per hour.


             59          (b) [A] Except as provided in Subsection (3)(c), a posted speed limit on a freeway or
             60      other limited access [highways] highway may not exceed 75 miles per hour.
             61          (c) (i) The department may establish a posted speed limit on a freeway or other limited
             62      access highway that exceeds the maximum speed limit in Subsection (3)(b) if the speed limit
             63      is:
             64          (A) based on a highway traffic engineering and safety study; and
             65          (B) is located on a portion of the interstate system that is between milepost 222 and
             66      milepost 64.
             67          (ii) The department shall consider the roadway geometry and population density that
             68      may be appropriate for a higher speed limit when establishing a speed limit under this
             69      Subsection (3)(c).
             70          (iii) If the department establishes a posted speed limit that exceeds the limit under
             71      Subsection (3)(b), the department shall evaluate the results and impacts of increasing a speed
             72      limit under Subsection (3)(c).
             73          (iv) The department shall report the findings of an evaluation conducted under
             74      Subsection (3)(c)(iii) to the Transportation Interim Committee no later than one year after a

             77      (2).

             80          (a) the county for state highways in an unincorporated area of the county;
             81          (b) the municipality for state highways within the municipality's incorporated area;
             82          (c) the Department of Public Safety; and
             83          (d) the Transportation Commission.
             84          (5) The speed limit is effective when appropriate signs giving notice are erected along
             85      the highway or section of the highway.
             86          Section 2. Section 41-6a-704 is amended to read:
             87           41-6a-704. Overtaking and passing vehicles proceeding in same direction.
             88          (1) (a) On any highway:
             89          [(a)] (i) the operator of a vehicle overtaking another vehicle proceeding in the same


             90      direction shall:
             91          [(i)] (A) except as provided under Section 41-6a-705 , promptly pass the overtaken
             92      vehicle on the left at a safe distance; and
             93          [(ii)] (B) enter a right-hand lane or the right side of the roadway only when safely clear
             94      of the overtaken vehicle;
             95          [(b)] (ii) the operator of an overtaken vehicle:
             96          [(i)] (A) shall give way to the right in favor of the overtaking vehicle; and
             97          [(ii)] (B) may not increase the speed of the vehicle until completely passed by the
             98      overtaking vehicle.
             99          (b) The exemption from the minimum speed regulations for a vehicle operating on a
             100      grade under Section 41-6a-605 does not exempt the vehicle from promptly passing a vehicle as
             101      required under Subsection (1)(a)(i)(A).
             102          (2) On a highway having more than one lane in the same direction, the operator of a
             103      vehicle traveling in the left general purpose lane:
             104          (a) shall, upon being overtaken by another vehicle in the same lane, yield to the
             105      overtaking vehicle by moving safely to a lane to the right; and
             106          (b) may not impede the movement or free flow of traffic in the left general purpose
             107      lane.
             108          (3) An operator of a vehicle traveling in the left general purpose lane that has a vehicle
             109      following directly behind the operator's vehicle at a distance so that less than two seconds
             110      elapse before reaching the location of the operator's vehicle when space is available for the
             111      operator to yield to the overtaking vehicle by traveling in the right-hand lane is prima facie
             112      evidence that the operator is violating Subsection (2).
             113          (4) The provisions of Subsection (2) do not apply to an operator of a vehicle traveling
             114      in the left general purpose lane when:

             116      accordance with Subsection (1)(a);
             117          (b) preparing to turn left or taking a different highway or an exit on the left;
             118          (c) responding to emergency conditions;

             120      or merging lane; or


             121          (e) following the direction of a traffic-control device that directs the use of a designated
