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)
“I take this evanescence and lubricity of all objects, which lets them slip through our fingers then when we clutch hardest, to be the most unhandsome part of our condition.”
—Ralph Waldo Emerson (1803–1882)
