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:
“One key, one solution to the mysteries of the human condition, one solution to the old knots of fate, freedom, and foreknowledge, exists, the propounding, namely, of the double consciousness. A man must ride alternately on the horses of his private and public nature, as the equestrians in the circus throw themselves nimbly from horse to horse, or plant one foot on the back of one, and the other foot on the back of the other.”
—Ralph Waldo Emerson (1803–1882)
““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)
