Truck \Truck\, v. t. [imp. & p. p. {Trucked}; p. pr. & vb. n. {trucking}.] [OE. trukken,F. troquer; akin to Sp. & Pg. trocar; of uncertain origin.] To exchange; to give in exchange; to barter; as, to truck knives for gold dust. We will begin by supposing the international trade to be in form, what it always is in reality, an actual trucking of one commodity against another. --J. S. Mill.
