W.S. 31-18-802 applies the federal 80,000 lb gross standard. ⚠️ Wyoming additionally holds a GRANDFATHER right under 23 U.S.C. 127(d) permitting up to 117,000 lb GVW on several DESIGNATED ROUTES, including portions of the Interstate system. The figure shown is the limit that holds everywhere in the state; 117,000 lb is route-specific and was previously published here as if it were the general limit. Confirm your exact route with WYDOT before loading above 80,000 lb.

W.S. 31-18-802: no vehicle, unladen or with load or load-holding devices, may exceed 14 ft (168 in) in height. Implements and produce of husbandry of greater height may move in agricultural operations during daylight without permit or fee, under WYDOT rules.

W.S. 31-18-802(a)(iv)(B): "In a truck-tractor semitrailer combination, no semitrailer shall exceed sixty (60) feet in length." Wyoming is a 60 ft state — notably MORE permissive than the federal 53 ft floor, so publishing 53 here would send a carrier for a permit they do not need. ⚠️ Our previous 85 ft is the same subsection's residual clause — "For any other combination of vehicles the overall length shall not exceed eighty-five (85) feet" — which expressly does NOT apply to a standard tractor-semitrailer. The Wyoming Highway Patrol page lists 60/81/85 as a flat bullet list under "Statutory Size Limits", which is the likely route by which 85 became our headline. Limits are stated as "Length-all highways", so there is no road-class split; the 31-18-803(a) exception covers auto/saddlemount transporters only.
