“Less than truckload” shipping is often shortened to LTL shipping. This type of freight shipping method involves packing small parcels into pallets and transporting them on a trailer, with the shipper paying for the amount of space their product takes up and the distance it travels. Many industries ship their products with LTL freight shipping, and many factors can influence the shipping rates for LTL freight. LTL shipping has a seasonal increase in demand, but due to a number of factors that demand is expected to continue rising.
