The term 'MOVING TRUCK' can be solved by the three-letter word 'VAN'. A VAN is a type of vehicle that is typically used for transporting goods or people. It is usually larger than a car and has an open back, making it ideal for moving items from one place to another. A moving truck is a large VAN that is specifically designed for moving furniture and other large items. It is usually equipped with a ramp and straps to secure the items during transport.
