A tandem axle is defined as two or more consecutive axles whose centers are spaced more than 40 inches (102 cm) but not more than 96 inches (244 cm) apart. [10] Axles spaced less than 40 inches (102 cm) apart are considered a single axle. [11] In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below
Each standard tracked vehicle is also defined in terms of track width, length, and spacing. Standard wheeled vehicles are designated by the same MLC numbers (4 through 150), which correspond to about 85% of the gross weight in short tons.
