Axle Weight Limits
Validate legal gross and axle weights for a standard 5-axle tractor-trailer combination (18-wheeler) on the US Interstate system.
Note: Axle distribution varies wildly based on exactly where pallets are placed inside the trailer. This tool assumes an even distribution of cargo weight between the Drive and Trailer tandem axles, which represents an ideal load plan.
