  Except as provided in subsection (c), it is unlawful for any person to operate or drive a motor vehicle upon any highway or public road of this state in excess of sixty-five miles per hour (65 mph).   “Truck,” as used in this section, means any motor vehicle of one and one-half (1½) ton rated capacity or more.   On all controlled-access highways with four (4) or more lanes, which are designated as being on the state system of highways or the state system of interstate highways, it is unlawful for any person to operate or drive a motor vehicle or a truck at a rate of speed in excess of seventy miles per hour (70 mph). In the left-hand lane of all controlled-access highways with four (4) or more lanes, which are designated as being on the state system of highways or the state system of interstate highways, it is unlawful for any person to operate or drive a motor vehicle at a rate of speed less than fifty-five miles per hour (55 mph).     Except as provided for certain counties in subdivision (d)(2), counties and municipalities are authorized to establish special speed limits upon any highway or public road of this state within their jurisdiction, except at school entrances and exits to and from controlled access highways on the system of state highways, which is adjacent to school grounds that are devoted primarily to normal school day activity. Such speed limit shall be enacted based on an engineering investigation, shall not be less than fifteen miles per hour (15 mph) and shall be in effect only when proper signs are posted with a warning flasher or flashers in operation and only while children are actually present.   In any county or municipality where the local legislative body does not establish special speed limits as provided for above, any person who shall drive at a speed exceeding fifteen miles per hour (15 mph) when passing a school during a recess period when a warning flasher or flashers are in operation, or during a period of ninety (90) minutes before the opening hour of a school or a period of ninety (90) minutes after the closing hour of a school, while children are actually going to or leaving school, shall be prima facie guilty of reckless driving.   The department of transportation has the authority to establish such special speed limits at school entrances and exits to and from controlled access highways on the system of state highways.     In counties of not less than forty-three thousand seven hundred (43,700) nor more than forty-three thousand eight hundred (43,800) and counties of not less than one hundred forty-three thousand (143,000) nor more than one hundred forty-five thousand (145,000) and counties of not less than eighty-five thousand seven hundred twenty-five (85,725) nor more than eighty-five thousand eight hundred twenty-five (85,825) and counties of not less than four hundred seventy-seven thousand eight hundred (477,800) nor more than four hundred seventy-seven thousand nine hundred (477,900), according to the 1980 federal census or any subsequent federal census, counties and municipalities are authorized to establish special speed limits upon any highway or public road of this state within their jurisdiction, except at school entrances and exits to and from controlled access highways on the system of state highways, which is adjacent to or within one-fourth (¼) mile of school grounds that are devoted to normal school day activities. Such speed limit shall be enacted based on an engineering investigation and shall not be less than fifteen miles per hour (15 mph) and shall be in effect only when proper signs are posted with a warning flasher or flashers in operation. In any county or municipality where the local legislative body does not establish special speed limits as provided for above, any person who drives at a speed exceeding fifteen miles per hour (15 mph) when passing a school during a recess period when a warning flasher or flashers are in operation, or during a period of forty (40) minutes before the opening hour of a school or a period of forty (40) minutes after the closing hour of a school, while children are actually going to or leaving school, is prima facie guilty of reckless driving. The department of transportation has the authority to establish such special speed limits at school entrances and exits to and from controlled access highways on the system of state highways.      The fees of sheriffs, deputy sheriffs and other police officers, other than salaried officers, for making arrests for violations of the speed restrictions of this chapter, shall be one dollar ($1.00).   The reference to sheriffs, deputy sheriffs and other police officers in subdivision (e)(1) also includes constables in counties of this state having a population of:  not less than  nor more than   3,700 4,700   6,000 7,800   8,400 8,500   8,535 8,540   9,200 9,570   10,770 10,780   11,512 11,550   11,700 11,900   12,000 13,000   14,500 14,600   15,300 15,500   15,750 16,000   17,000 17,350   18,000 18,200   18,300 18,900   19,000 19,100   21,000 21,500   21,600 22,300   23,200 23,350   23,355 23,391   23,391 23,450   23,500 23,750   24,000 24,255   25,600 27,500   27,900 28,000   28,555 28,600   29,250 31,250   31,260 33,000   33,700 34,000   35,480 41,800   41,900 50,000   57,550 59,400   59,500 60,050   60,600 62,000   64,000 65,000   101,000 118,400   118,700 200,000   according to the 1960 federal census or any subsequent federal census, and Fentress and Hamblen counties.        Notwithstanding 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. This authorization to reduce the speed limits set by this section shall be in addition to the authority conveyed by § 55-8-153.   When the department determines 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.   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 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).     Notwithstanding any 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 that violation, nor shall any costs be imposed or assessed against the person. Costs shall be imposed in such cases should the person fail to appear or answer the traffic citation as required by law. The conviction shall not be reported to the department of safety under §§ 55-10-306 and 55-12-115. Such person shall not be required to attend driver education course as provided in § 55-10-301. The conviction for speeding shall not result in suspension or revocation of operator's or chauffeur's license unless the excess speed constitutes 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 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.      Notwithstanding any 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). This fine shall be in addition to any fine assessed under this or any other applicable section.   Fines collected pursuant to subdivision (g)(1) shall be placed in a fund to be established by such county. The fund shall be for the sole purpose of erecting and maintaining highway signs.   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.     Notwithstanding any 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.
