A double clutch (also called a double declutch) is a method of shifting gears primarily used for vehicles with an unsynchronized manual transmission, such as commercial trucks and specialty vehicles.
With this method, instead of pushing the clutch in once and shifting directly to another gear, the driver first shifts the transmission into neutral before shifting to the next gear. The clutch is pressed with each change.

Famous quotes containing the words double and/or clutch:
“In a symbol there is concealment and yet revelation: here therefore, by silence and by speech acting together, comes a double significance.... In the symbol proper, what we can call a symbol, there is ever, more or less distinctly and directly, some embodiment and revelation of the Infinite; the Infinite is made to blend itself with the Finite, to stand visible, and as it were, attainable there. By symbols, accordingly, is man guided and commanded, made happy, made wretched.”
—Thomas Carlyle (1795–1881)
““you were with me all day; stood with me, sat with me, talked with me, looked at me, ate with me, drank with me; and yet, your last act was to clutch for a monster, not only an innocent man, but the most pitiable of all men. So far may even the best man err, in judging the conduct of one with the recesses of whose condition he is not acquainted.””
—Herman Melville (1819–1891)
