Notwithstanding the preceding table, two successive sets of tandem axles may each support a gross load of thirty-four thousand pounds if the total distance between the first and last axles of these successive sets of tandem axles is thirty-six feet or more. (4) If the State Highways and Transportation Commission determines that a state highway bridge in the state is in such a condition that the use of the bridge by vehicles of the weights referred to in subsection 3 of this section endangers the bridge or the users of the bridge, the Board may establish maximum weight and speed limits for vehicles using the bridge. The governing body of a city or county may, by statute or regulation, give the State Highways and Transportation Commission the power to enact the restrictions set forth in this section on such highways under the jurisdiction of that city or county. The weight and speed limits set by the Commission shall be announced by the posting of conspicuous signs at each end of such a bridge. The maximum permissible axle weights for permits are as follows: The maximum permissible weight in Missouri per axle is 20,000 pounds on the highway and 22,000 pounds on non-interstate highways. The maximum weight allowed per tandem is 34,000 pounds on the highway and 36,000 pounds on non-interstate highways. This applies to roads that are not marked with lower weight restrictions. (5) Nothing in this section shall be construed as permitting regulatory axle loads, tandem axle loads, or gross loads greater than those permitted under the provisions of 23 U.S.C. § 127.
6. Notwithstanding the weight restrictions set out in this section, vehicles or combinations of vehicles used on highways other than the Interstate Highway System shall not exceed the gross weight restrictions for a single axle, tandem axle and tandem axle by more than two thousand pounds. However, the total gross weight may not exceed eighty thousand pounds. (3) Subject to the weight limitation imposed on a highway in that state by an axle or tandem axle, the total weight with load caused by a group of two or more successive axles of a vehicle or combination of vehicles shall not exceed the maximum load in pounds specified in the following table: (1971) The limit values laid down in § 304.180 RSMo for single axles, tandem axles and gross permissible laden weight are cumulative and must be complied with in each case. The State is not required to prove intent to violate borders or knowledge of such a violation in support of a case. State v. Boze (A.), 472 S.W.2d 35. An “axle load” is defined as the total load transferred to the road from all wheels, the centres of which are placed between two parallel vertical transverse planes spaced forty inches apart, extending across the entire width of the vehicle. 46,000 pounds (but not more than 24,000 pounds for each axle in a multi-axis group) 304,180. 1.
No vehicle or combination of vehicles may be moved or operated on a highway of that State weighing more than twenty thousand pounds on an axle, no combination of vehicles operated by general cargo carriers on regular routes within the meaning of section 390.020, RSMo, may be moved or operated on a highway of that State, which weighs more than the vehicle manufacturer`s indication on a steered axle with the maximum weight. twelve thousand pounds on a steered axle, and no vehicle shall be driven or driven on any national highway of that State weighing more than thirty-four thousand pounds on a tandem axle; The term “tandem axle” means a group of two or more successive axles spaced between the outermost parts of more than forty inches and not more than ninety-six inches.
