(f) (1) (A) Notwithstanding any provision of this section to the contrary, the department is authorized to lower the speed limits prescribed in this section, and on the state system of roads and highways, as it deems appropriate due to concerns regarding the roadway, traffic, or other conditions. Such authorization to reduce the speed limits set by this section shall be in addition to the authority conveyed by § 55-8-153.

(B) When the department shall determine that it is necessary to reduce the speed limits set in subsection (a), the commissioner shall so indicate the reduced speed limit via a letter of policy statement, and the commissioner shall cause signs indicating the new speed limit to be erected.

(C) Subject to § 55-8-153(c), the municipalities of the state are authorized to set speed limits on the public roads and streets within their jurisdictions that are not a part of the interstate and national defense highway system nor any access controlled highway on the state road and highway system. In addition, the counties of this state are hereby authorized to set speed limits on the public roads and highways within their jurisdiction that are not a part of the interstate or state highway system. The speed limits for both municipalities and counties shall not exceed fifty-five miles per hour (55 mph).

(2) Notwithstanding any provision of the law to the contrary, during the period in which this subsection (f) is in effect, any person who is arrested or receives a traffic citation for driving or operating a motor vehicle in excess of fifty-five miles per hour (55 mph) but less than seventy-five miles per hour (75 mph) on a highway of the interstate and defense highway system or a four-lane controlled-access highway which are federal or state highways, or in excess of fifty-five miles per hour (55 mph) or less than sixty-five miles per hour (65 mph) on a highway or road which has an existing speed limit of sixty-five miles per hour (65 mph) as of March 1, 1974, shall be charged with speeding and upon conviction shall not be fined more than the maximum fine nor less than the minimum fine for speeding as provided by law for such violation, nor shall any costs be imposed or assessed against such person. Costs shall be imposed in such cases should such person fail to appear or answer the traffic citation as required by law. Such conviction shall not be reported to the department of safety under the provisions of §§ 55-10-306 and 55-12-115. Such person shall not be required to attend driver education course as provided in § 55-10-301. Such conviction for speeding shall not result in suspension or revocation of operator's or chauffeur's license unless the excess speed is such as to constitute reckless driving, as set out herein. This subsection (f) shall not apply to trucks as defined in subsection (b) when traveling in excess of sixty-five miles per hour (65 mph) on all highways of the interstate and defense highway system and four-laned controlled-access highways, which are federal or state routes of this state or when traveling in excess of fifty-five miles per hour (55 mph) on any other highways of this state. A violation of this subsection (f) is a Class C misdemeanor. However, notwithstanding any provision of the law to the contrary, a violation of the reduced speed limits set by the department of transportation, pursuant to § 55-8-153, is a Class B misdemeanor, punishable by fine only, when employees of the department or construction workers are present. The amount of the fine imposed pursuant to § 55-8-153 shall not be less than two hundred fifty dollars ($250) nor more than five hundred dollars ($500). Notwithstanding any provision of this subsection (f) to the contrary, no provision of this subsection (f), nor of § 55-8-153, shall be construed so as to prevent the entry of a suspended sentence upon the conviction of a defendant for the first violation of the enhanced penalties provided for when the violation occurs within a work zone and when employees of the department of transportation or construction workers are present and when the trier of fact determines that extraordinary circumstances lead to the violation.

(g) (1) Notwithstanding any provision of the law to the contrary, any county having a population of not less than sixty-seven thousand five hundred (67,500) nor more than sixty-seven thousand six hundred (67,600) according to the 1980 federal census or any subsequent federal census may assess any person who is arrested or receives a traffic citation for driving or operating a motor vehicle in excess of the posted speed limits an additional fine of five dollars ($5.00). Such fine shall be in addition to any fine assessed under this or any other applicable section.

(2) Fines collected pursuant to subdivision (g)(1) shall be placed in a fund to be established by such county. Such fund shall be for the sole purpose of erecting and maintaining highway signs.


(3) This subsection (g) shall have no effect unless it is approved by a two-thirds (2/3) vote of the legislative body of any county to which it may apply. Its approval or nonapproval shall be proclaimed by the presiding officer of the county legislative body and certified by the presiding officer to the secretary of state.

(h) Notwithstanding any provision of law or regulation to the contrary, only the department of transportation has the authority to set speed limits on access-controlled roadways designated as being on the state system of highways and on roadways designated as being on the state system of interstate highways.
