As used in this subsection, “agricultural commodity” means inputs limited to feed, seed and fertilizer and products of agriculture, as described in subsection (q) of section 1-1.

(c) The weight per inch width of tire on any single vehicle or combination of vehicles equipped with pneumatic tires, when loaded, shall be not more than six hundred pounds. The sum of the widths of all the tires on a wheel or combination of wheels shall be taken in determining tire width. For the purposes of this section, the width of pneumatic tires shall be determined in conformity with the manufacturer’s designated width on the tire. A vehicle or combination of vehicles equipped with any solid rubber tires shall not have weights more than eighty per cent of those permitted in this section for pneumatic tires. The width of solid rubber tires shall be ascertained by measuring the width of the tire base channel or between the flanges of the metal rim. No vehicle equipped with solid tires which have at any point less than one inch of rubber above the top or beyond the flange or rim shall be operated upon a public highway.

(2) Any person who violates any provision of this section shall be subject to the following penalties: (A) For an overweight violation of not more than five per cent of the gross weight or axle weight limits in subsection (b) of this section, a fine of three dollars per hundred pounds or fraction thereof of such excess weight; (B) for an overweight violation of more than five per cent and not more than ten per cent of either such weight limit, a fine of five dollars per hundred pounds or fraction thereof of such excess weight or a minimum fine of fifty dollars; (C) for an overweight violation of more than ten per cent but not more than fifteen per cent of either such weight limit, a fine of six dollars per hundred pounds or fraction thereof of such excess weight or a minimum fine of one hundred dollars; (D) for an overweight violation of more than fifteen per cent but not more than twenty per cent of either such weight limit, a fine of seven dollars per hundred pounds or fraction thereof of such excess weight or a minimum fine of two hundred dollars; (E) for an overweight violation of more than twenty per cent but not more than twenty-five per cent of either such weight limit, a fine of ten dollars per hundred pounds or fraction thereof of such excess weight or a minimum fine of three hundred dollars; (F) for an overweight violation of more than twenty-five per cent but not more than thirty per cent of either such overweight limit, a fine of twelve dollars per hundred pounds or fraction thereof of such excess weight or a minimum fine of five hundred dollars; and (G) for an overweight violation of more than thirty per cent of either such overweight limit, a fine of fifteen dollars per one hundred pounds or fraction thereof of such excess weight or a minimum fine of one thousand dollars.

(3) The court shall note on the record any conviction for an overweight violation in excess of fifteen per cent of the gross weight limits in subsection (b) of this section with respect to any vehicle with a gross vehicle weight of eighteen thousand pounds or more and shall cause such information to be transmitted to the Commissioner of Motor Vehicles. Upon receipt of such information with respect to a third or subsequent conviction for such overweight violation in a calendar year, the commissioner may schedule a hearing, in accordance with the provisions of chapter 54, to review the record of the motor vehicle registrant and shall notify the registrant of the hearing. In such cases, the Commissioner of Motor Vehicles may review information and evidence presented at the hearing including, but not limited to, frequency of the registrant’s commercial vehicle operations, the size of the registrant’s fleet and the culpability, if any, of the shipper. After the hearing, the commissioner may impose a civil penalty on the owner or lessee of such motor vehicle in the amount of two thousand dollars or revoke the registration, for a period of thirty days, of any commercial motor vehicle so operated and may refuse to issue a registration for such motor vehicle during such further time as the commissioner deems reasonable.

(4) An owner or lessee who is assessed penalties pursuant to this subsection for an overweight violation in excess of fifteen per cent of the gross weight limits in subsection (b) of this section five times during any calendar year shall be assessed by the court an additional five thousand dollars for the fifth violation and an additional five thousand dollars for each subsequent overweight violation in excess of fifteen per cent of such limits in such calendar year.

(5) No more than twenty-five per cent of any fine imposed pursuant to this subsection may be remitted unless the court determines that there are mitigating circumstances and specifically states such circumstances for the record.

(h) Whenever signs are displayed on a public highway, indicating that a scale is in operation and directing the driver of a motor vehicle described in subsection (a) of section 14-163c to stop at the weighing area, the driver shall stop and, in accordance with the directions of any state police officer, local police officer, Department of Motor Vehicles inspector, or Department of Motor Vehicles employee designated by the Commissioner of Motor Vehicles, allow the vehicle to be weighed or inspected.

(i) The driver of a vehicle which is weighed may remove from such vehicle any material, including, but not limited to, sand, debris, ice or snow, which may have accumulated on the outside of such vehicle, before any such official determines that the weight of such vehicle is unlawful.

(j) Whenever such an official, upon weighing a vehicle and load, determines that the weight is unlawful, such official may require the driver to remove from the vehicle that portion of the load that may be necessary to reduce the gross or axle weight of such vehicle to the limit permitted under this chapter, provided if the vehicle is in violation of an axle weight limit in subsection (b) of this section but not a gross weight limit under said subsection, such official shall allow the driver to manually shift the load in order to comply with such axle weight limit without penalty.

(k) (1) Any driver of a vehicle who fails or refuses when directed by such official, upon a weighing of the vehicle, to comply with such official’s directions shall be fined not less than one hundred dollars or more than two hundred dollars for the first offense and not less than two hundred dollars or more than five hundred dollars for each subsequent offense.
