(4) The Department of Transportation may establish light-traffic roads and further restrict the axle weight limit on such light-traffic roads lower than the statutory limits. The Department of Transportation has the authority to designate any highway on the State Highway System, excluding routes designated by I, U.S. and N.C., as a light-traffic road when in the opinion of the Department of Transportation, the road is inadequate to carry and will be injuriously affected by vehicles using the road carrying the maximum axle weight. All such roads so designated shall be conspicuously posted as light-traffic roads and the maximum axle weight authorized shall be displayed on proper signs erected thereon.
(c) Exceptions. – The following exceptions apply to subsections (b) and (e) of this section:
(1) Two consecutive sets of tandem axles may carry a gross weight of 34,000 pounds each without penalty provided the overall distance between the first and last axles of the consecutive sets of tandem axles is 36 feet or more.
(2) When a vehicle is operated in violation of subdivision (b)(1), (b)(2), or (b)(3) of this section, but the gross weight of the vehicle or combination of vehicles does not exceed that permitted by subdivision (b)(3) of this section, the owner of the vehicle shall be permitted to shift the load within the vehicle, without penalty, from one axle to another to comply with the weight limits in the following cases:
a. Where the single-axle load exceeds the statutory limits, but does not exceed 21,000 pounds.
b. Where the vehicle or combination of vehicles has tandem axles, but the tandem-axle weight does not exceed 40,000 pounds.
(3) When a vehicle is operated in violation of subdivision (b)(4) of this section, the owner of the vehicle shall be permitted, without penalty, to shift the load within the vehicle from one axle to another to comply with the weight limits where the single-axle weight does not exceed the posted limit by 2,500 pounds.
(4) A truck or other motor vehicle shall be exempt from the light-traffic road limitations provided for pursuant to subdivision (b)(4) of this section, when transporting supplies, material, or equipment necessary to carry out a farming operation engaged in the production of meats and agricultural crops and livestock or poultry by-products or a business engaged in the harvest or processing of seafood when the destination of the vehicle and load is located solely upon a light-traffic road.
(5) The light-traffic road limitations provided for pursuant to subdivision (b)(4) of this section do not apply to a vehicle while that vehicle is transporting only the following from its point of origin on a light-traffic road to either one of the two nearest highways that is not a light-traffic road. If that vehicle's point of origin is a non-light-traffic road and that road is blocked by light-traffic roads from all directions and is not contiguous with other non-light-traffic roads, then the road at point of origin is treated as a light-traffic road for purposes of this subdivision:

These penalties apply separately to each weight limit violated. In all cases of violation of the weight limitation, the penalty shall be computed and assessed on each pound of weight in excess of the maximum permitted.
(2) The penalty for a violation of the single-axle or tandem-axle weight limits by a vehicle that is transporting an item listed in subdivision (c)(5) of this section is one-half of the amount it would otherwise be under subdivision (1) of this subsection.
(3) If an axle-group weight of a vehicle exceeds the weight limit set in subdivision (b)(3) of this section plus any tolerance allowed in subsection (h) of this section or axle-group weights or gross weights authorized by special permit under G.S. 20-119(a), the Department of Public Safety shall assess a civil penalty against the owner or registrant of the motor vehicle. The penalty shall be assessed on the number of pounds by which the axle-group weight exceeds the limit set in subdivision (b)(3) of this section, or by a special permit issued pursuant to G.S. 20-119, as follows: for the first 2,000 pounds or any part thereof, two cents (2) per pound; for the next 3,000 pounds or any part thereof, four cents (4) per pound; for each pound in excess of 5,000 pounds, ten cents (10) per pound. Tolerance pounds in excess of the limit set in subdivision (b)(3) of this section are subject to the penalty if the vehicle exceeds the tolerance allowed in subsection (h) of this section.
These penalties apply separately to each axle-group weight limit violated. Notwithstanding any provision to the contrary, a vehicle with a special permit that is subject to additional penalties under this subsection based on a violation of any of the permit restrictions set out in G.S. 20-119(d1) shall be assessed a civil penalty, not to exceed ten thousand dollars ($10,000), based on the number of pounds by which the axle-group weight exceeds the limit set in subdivision (b)(3) of this section.

(h) Tolerance. – A vehicle may exceed maximum and the inner axle-group weight limitations set forth in subdivision (b)(3) of this section by a tolerance of ten percent (10%). This exception does not authorize a vehicle to exceed either the single-axle or tandem-axle weight limitations set forth in subdivisions (b)(1) and (b)(2) of this section, or the maximum gross weight limit of 80,000 pounds. This exception does not apply to a vehicle exceeding posted bridge weight limitations as posted under G.S. 136-72 or to vehicles operating on interstate highways. The tolerance allowed under this subsection does not authorize the weight of a vehicle to exceed the weight for which that vehicle is licensed under G.S. 20-88. No tolerance on the single-axle weight or the tandem-axle weight provided for in subdivisions (b)(1) and (b)(2) of this section shall be granted administratively or otherwise.
