How much does a loaded dump truck weigh?

That varies depending on configuration and state law. A tandem axle truck will typically be permitted 54,000 lbs. A quad axle dump in North Carolina could be permitted up to 66,000 lbs (allowable gross weight varied according to the vehicle wheelbase). A single axle is permitted 33,000 lbs. by federal regs, though some states may allow up to 40,000.
