Left-foot braking is the technique of using the left foot to operate the brake pedal in an automobile, leaving the right foot dedicated to the throttle pedal. It contrasts with the practice of using the left foot to operate the clutch pedal, leaving the right foot to share the duties of controlling both brake and accelerator pedals.
At its most basic purpose, left-foot braking can be used to decrease the time spent between the right foot moving between the brake and throttle pedals, and can also be used to control load transfer.
It is most commonly used in auto racing, but is also used by some drivers for use with an automatic transmission, as the left foot is not needed to operate a clutch pedal.
