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:
“Was it the double of my dream
The woman that by me lay
Dreamed, or did we halve a dream
Under the first cold gleam of day?”
—William Butler Yeats (1865–1939)
“...I remembered the rose bush that had reached a thorny branch out through the ragged fence, and caught my dress, detaining me when I would have passed on. And again the symbolism of it all came over me. These memories and visions of the poor—they were the clutch of the thorns. Social workers have all felt it. It holds them to their work, because the thorns curve backward, and one cannot pull away.”
—Albion Fellows Bacon (1865–1933)
