In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer.

The Class 8 truck gross vehicle weight rating (GVWR) is a vehicle with a GVWR exceeding 33,000 lb (14,969 kg). [ 2 ] [ 28 ] These include tractor trailer tractors, single-unit dump trucks of a GVWR over 33,000 lb, as well as non-commercial chassis fire trucks; such trucks typically have 3 or more axles.

Truck (total weight 30 tonnes, 3 axles): load per axle: 10 tonnes 10 4 = 10 ⋅ 10 ⋅ 10 ⋅ 10 = 10 , 000 {\displaystyle 10^{4}=10\cdot 10\cdot 10\cdot 10=10,000} times as large The load on the road from one axle (2 wheels) is 10 times greater for a truck than for a car.

This means that doubling the axle weight will increase road damage (2×2×2×2)=16 times. [14] [15] For this reason, trucks with a high axle weight are heavily taxed in most countries. Examples of GAWR on common axles:
The federal gross weight limit for a Class 8 truck is 80,000 pounds (36,000 kg) (combined weight of truck, trailer, and cargo) with axle weights limited to 12,000 pounds (5,400 kg) (steering axle) and 34,000 pounds (15,000 kg) (tandem axles).

125 feet (38 m) long oversize load "Superload" The legal dimensions and weights vary between countries and regions within a country. [2] A vehicle which exceeds the legal dimensions usually requires a special permit which requires extra fees to be paid in order for the oversize/overweight vehicle to legally travel on the roadways.
