... The United States may consider allowing larger and/or heavier trucks across the national road network. The process used in Canada to harmonize truck size and weight regulations in the 1980s Review of Canadian Experience with the Regulation of Large Commercial Motor Vehicles 1
From page 2...
... Axle and gross weights are uniform in the four western provinces, and also uniform, but higher, in the six eastern provinces for vehicles outside of the M.o.U. Coordination of Truck Size and Weight Regulations The Canadian federal government has no truck size and weight regulations.

... In fact, they have done very well, acquiring U.S. lines, abandoning unprofitable branch lines in Canada, sharing track, and developing intermodal service into the single fastest growing transportation sector.
From page 4...
... Application of Canadian Experience to the United States -- Conclusions Truck size and weight regulation is abstruse, complex, highly technical, and has multiple close linkages with roadway, pavement, and bridge design; construction, maintenance and management; road safety, road capacity, and congestion; energy, emissions, rail transportation, and others. The public at large does not view trucks favorably, and especially does not like the concept of a larger or heavier truck.
From page 5...
... In addition, if the jurisdictions have different allowable axle group weights, or allowable gross weight, the configuration should be able to be loaded to its allowable gross weight in each jurisdiction within the allowable axle loads and internal dimension limits. Canada's process developed a performance-based method to assess the dynamic performance of vehicles, which was used as the basis for the national configurations, and has been used subsequently by all provinces when considering new configurations, either for regulation or for special permits.
From page 6...
... The United States has essentially not made any changes to its size and weight regulations since NAFTA became effective, while Canada and Mexico have both continued to develop their own truck size and weight regulations, which, coincidentally, have many similarities and considerable domestic benefit. Harmonization with the NAFTA partners to the extent possible with the intent of achieving more uniform transportation efficiency within North America could present a compelling argument for change.
