Weight of the cargo in a semi-truck

Trucks are categorized depending on their weight capacity, measured in tonnage.

A 10-wheeler can hold 12 to 13 tons, a straight truck or 18-wheeler (semi) is 28 to 29.5 tons, and a heavy haul has a capacity of up to 44 tons.

A semi-truck that carries an average cargo weight of 36,000 pounds requires about 1 mile per gallon.

What will happen if I exceed my truck’s towing capacity

If your semi-truck exceeds its capacity, it will strain the engine, causing a decrease in speed.

You must not exceed this weight because it puts you and others in danger on the road.

To prevent possible accidents caused by super heavy-duty trucks, states have implemented laws about their maximum towing capacity.

Federal Motor Carrier Safety Administration is one agency that monitors truck weights nationwide.

What are the penalties for exceeding my truck’s towing capacity

If found on public roads, trucks that exceed their allowable limits will be confiscated by authorities.

What are the costs of having an overweight semi-truck towed

You’ll be charged several fees if authorities seize your truck for exceeding its weight limit.

There’s a fine per axle of the truck (it varies depending on the axle’s weight) and storage fees for having it towed.

An overweight truck can’t be released to you if you don’t pay its penalties and expenses.

For every 15 minutes an overloaded semi-truck is on the road, you’re charged with a minimum of $500. This fee will increase as time goes by, depending on where it’s hauled.

Semi-trucks are equipped with several safety features like air brakes, anti-lock braking systems, and electronic stability control.

But before all these were made mandatory for truckers, there was already a limit on how owners of their tractors could haul heavy vehicles. The maximum is 80,000 pounds.

A trucker who’s operating a super heavy-duty semi-truck weighing 83,000 pounds is not supposed to haul cargo weighing more than 70,000 pounds.


A semi-truck with a stopping time of 10 seconds and 100 feet has a total weight of about 40,000 pounds.

The greatest weight it can carry is 70,000 pounds.

State laws limit the towing capacity of trucks depending on their weight, size, and cargo type.

Trucks that exceed these limits will be subjected to penalties, including fines and confiscation.

Trucks haul cargo weighing about 36,000 pounds on average.

The biggest can carry up to 80,000 pounds, and the smallest is 29.5 tons or less than 44,000 pounds.
