In 2010 the Environmental Protection Agency, or EPA, put emissions standards in place to control the diffusion of particulate matter and nitrogen oxide from heavy duty trucks. The trucking industry soon realized a potential workaround for these regulations: glider kits.
The truck cabs shown above look identical, and they might be carrying cargos that appear to be exactly alike, but their freight designations could be very different: some might be LTL (less-than-truckload) while others are TL (full truckload). From freight quote to booking a carrier, the initial stages of TL and LTL shipping have several differences that might surprise you. But first, we’ll look at why they both exist.
