at roadside inspections they usualy weigh each axle, or axel set, they look to see how much weight each axle or axle set has on it, there also looking to make sure the vehicle is designed to haul the gross weight it is carrying this is why, meduim duty and especially heavy duty trucks have numerous axle weight options available to them when spec'ing out a new truck, it depends on what the customer that is ordering the truck intends to do with it, example; a new truck going to a potato chip company running in the midwestern states, and a new truck intended to haul heavy equipment over the rocky mountains may look almost identical on the outside, under the sheetmetal, there completly different, dot must make sure the equipment used is cabable of carrying the load it has, also on say a 1 ton pulling a deckover trailer, with a tractor on it, same criteria applies, which is where not only gross weight is being checked, but where that weight is located on the vehicle, ie proper weight distribution, say you have that trailer under a farmall 706, if you have the tractor all the way foward to the front of the trailer, your going to be in for it, you will have too much weight on the truck's rear axle , possibly the trailers first axle, and not enough on its rear axle, move the tractor back several feet and you transfer that weight much more evenly [Reply]   [No Email]
