Universal Citation: WY Code of Rules 5-17

Current through September 21, 2024

(a) Permits may be obtained for a period not exceeding one year. These permits shall authorize the movement of vehicles without load, or meeting non-divisible load requirements. Class D permits shall also authorize movement of a trailer carrying a recreational boat that exceeds statutory weight limits and/or size limits up to 12 feet wide, 15 feet high, and 75 feet long for single vehicles. Class D permits are not authorized for transportable homes (see Section 4, Permit-issuing Authorities and Types of Permits Available).

(b) Class D oversize permits are issued to a specific unit, and if applicable, power unit, and/or load (a vehicle identification number or serial number shall be required for each specific piece of equipment indicated on the permit). If a piece of equipment is not shown on the permit, the permit is not valid for the move. Oversize vehicles may transport legal sized loads providing this is indicated on the permit.

(i) If required, vehicle(s) shall be properly qualified with Wyoming registration. Trip permits for registration shall not be allowed.

(ii) Multiple legal sized power units owned or leased and operated by the carrier may be indicated on the permit for size only.

(iii) Oversize power units may pull a trailer providing that specific trailer is indicated on the permit.

(iv) Class D oversize permits shall be obtained from the permit issuing authorities as listed in Section 4, Permit-issuing Authorities and Types of Permits Available. Applicants shall submit the information as directed in Section 16, Procedure for Obtaining Classes of Permits.

(c) Class D overweight permits shall be obtained from Wyoming ports of entry or from Department permit clerks.

(i) Class D overweight permits are issued to a specific power unit, and if applicable specific trailer and/or load (a vehicle identification number or serial number shall be required for each piece of equipment indicated on the permit). If a piece of equipment is not shown on the permit, the permit is not valid for the move. Class D overweight permits shall be accompanied by an original Class D tracking sheet(s) (with the exceptions discussed in following Section 17 [c][ii]). If the original tracking sheet(s) is lost, the overweight Class D permit is void.

(ii) The following may be exempt from the Class D tracking sheet requirements:
(A) Movers of heavy equipment not designed as highway vehicles, such as loaders or scrapers, who are able to supply an accurate number of miles traveled for a limited area (up to a 10-mile radius) or,

(B) Carriers who can supply an accurate number of miles by providing specific destination(s) and the number of trips.

(d) Class D overweight permits shall be requested for the shortest practical period and shall not exceed 6 months. If the operation will travel on both the primary and secondary and the interstate highway systems, the mileage is to be estimated for each of the highway systems, with a maximum of 5,000 total combined miles. Providing the fees are figured on the same amount of overweight for primary and secondary and interstate highways, the permit shall be honored until the total amount of combined miles for the two highway systems is met or the permit expires, whichever comes first.

(e) Any increase in size and/or weight exceeding legal limits or any change in equipment or configuration shall require a new permit.

(f) Violations of a permit's conditions may result in enforcement action including voiding of the permit and shall be considered sufficient cause to deny issuance of Class D permits.

(g) The permit fee for oversize is $50. The minimum permit fee for overweight is $40. The overweight fee is computed at the rate of 6 cents per ton per mile on weight exceeding the statutory limit.

(h) Any operation or movement other than authorized by the Class D permit shall require a Class A, B, C, or an additional D permit, as justified by specific conditions. Oversize vehicles may transport legal sized loads providing this is indicated on the permit.

(i) The permit, and original tracking sheet(s), if required, shall be carried in the specific vehicle. This permit is power unit, trailer, and load specific (vehicle identification number or serial number required) and shall be displayed to any permit-issuing authority or law enforcement upon request.

(j) Following are safety regulations governing Class D permits:

(i) All movements shall follow the provisions of Section 8, Safety Measures and Moves, of these rules and regulations.

(ii) Self-propelled equipment that requires and is properly displaying a slow moving emblem may, instead of oversize load signs and flags, display a lighted, revolving amber light, an amber strobe light, or 2 two-way flashing amber lights at least 4 inches in diameter on the vehicle. LED assemblies meeting the visibility requirements shall be allowed. These lights shall be clean and clearly visible at least 1,000 feet from the front and rear of the vehicle.

(iii) All snow removal equipment may operate 24 hours per day when the operation is authorized and stated on the permit. Snow removal equipment may instead of oversize load signs and flags, display a lighted, revolving amber light, an amber strobe light, or 2 two-way flashing amber lights at least 4 inches in diameter on the vehicle. LED assemblies meeting the visibility requirements shall be allowed. These lights shall be clean and clearly visible at least 1,000 feet from the front and rear of the vehicle. Vehicles authorized for snow removal operations may haul sand, for sanding operations or stability, up to the statutory weight limitations.

(iv) Vehicles used only by the Department to clear snow from public highways shall be equipped as specified by the Department.
