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:
“The worst feature of this double consciousness is, that the two lives, of the understanding and of the soul, which we lead, really show very little relation to each other; never meet and measure each other: one prevails now, all buzz and din; and the other prevails then, all infinitude and paradise; and, with the progress of life, the two discover no greater disposition to reconcile themselves.”
—Ralph Waldo Emerson (1803–1882)
“Go out of the house to see the moon, and ‘t is mere tinsel; it will not please as when its light shines upon your necessary journey. The beauty that shimmers in the yellow afternoons of October, who could ever clutch it? Go forth to find it, and it is gone: ‘t is only a mirage as you look from the windows of diligence.”
—Ralph Waldo Emerson (1803–1882)
