17、sMost important motor carrier are trucks Less than Truckload (LTL): 70kg to 4500kg do not quite fill a truck, generate load by combining many customer deliveriesOperate through Terminals, where freight is shifted between vehiclesTruckload (TL): Operate between terminals along line hauls to move bulk
