045-5 Wyo. Code R. § 5-5
The following have been exempted from one or more of the statutory limits:
(a) Towing of damaged, disabled, or abandoned oversize vehicles as prescribed in W.S. 31-18-808(a) on primary movement to the nearest point of safekeeping by a towing or wrecker company. Any subsequent (secondary) move of disabled oversize vehicles shall be reduced to meet non-divisible load requirements and shall require a separate oversize permit.
(b) Towing of damaged, disabled, or abandoned overweight vehicles. If a wrecker/combination unit is overweight when it is towing a vehicle or combination from a crash or motorist assist, the primary move shall be exempt from any permits whether traveling by a port of entry or not to the nearest point of safekeeping. Any subsequent (secondary) moves by a towing or wrecker company of a damaged, disabled, or abandoned overweight vehicle or combination after the first movement shall require a permit. Secondary tow permits for subsequent moves are available for a period not to exceed one year for a fee of $50 per tow truck and shall be reduced to meet non-divisible load requirements. Weights shall not exceed Class B limits.
(c) Implements and produce of husbandry. (Please see following Section 21, Implements and Produce of Husbandry Moved by Farmers and Ranchers, and Section 22, Implement Dealers.)
(d) Forest products, gravel, and agricultural products that cannot be weighed at the point of loading on primary and secondary highways ONLY. (Please see following Section 19, Class E and Class F Permits.)
(e) Permits for multi-piece divisible loads exceeding 117,000 pounds on primary and secondary highways ONLY. (Please see following Section 20, Class W Permits.)
(f) Non-commercial motor homes, house trailers, and truck campers in compliance with W.S. W.S. W.S. 31-18-802(a)(i)(A). (Please see following Section 18, Moves of Recreation Vehicles.)
(g) Off-load permits may be issued in special circumstances if a Department permit-issuing authority determines that a vehicle or load exceeding statutory limits cannot safely be reduced at the location where the violation was discovered. These permits authorize separate movements of divisible loads not exceeding Class B limits without Overweight Loads Office authority to the nearest location (figured by determining the least number of miles traveled on any highway) for reduction in size and/or weight. If the Department determines that carriers are abusing this permit, the load shall be reduced at the violation location or returned to point of loading, regardless of the cost or inconvenience to the carrier.
(h) For an over-the-road bus, public transit bus, or motor home, the weight limit on a single axle is increased to 24,000 pounds on interstate highways ONLY. As used in this paragraph, "motor home" means a multipurpose passenger vehicle with motive power that is designed to provide temporary residential accommodations, as evidenced by the presence of at least four of the following facilities: cooking, refrigeration or ice box, self-contained toilet, heating and/or air conditioning, a potable water supply system including a faucet and a sink, and a separate 100-125 volt electrical power supply and/or propane.
