Which is the Brake and Which is the Accelerator in a Motor Vehicle?

In a manual transmission vehicle, there are three pedals arranged from left to right: the first is the clutch, the second is the brake, and the third is the accelerator. The left foot controls the clutch, while the right foot controls the brake and accelerator. An automatic transmission vehicle has only two pedals, arranged from left to right: the brake pedal and the accelerator pedal, both controlled solely by the right foot. The brake system consists of brake calipers and brake pads installed on the wheel hubs, with a master brake cylinder installed in the driver's compartment. Brake cylinders can be hydraulic, pneumatic, or lever-type, and operating the master brake cylinder applies braking force to the moving vehicle. The accelerator controls the fuel injection volume of the engine. When the accelerator is pressed down, a larger fuel injection increases the engine speed, thereby making the vehicle move faster.
As a beginner learning to drive, I clearly remember my instructor teaching me that the pedal on the right is the accelerator—keep your left foot still and control it with your right foot—pressing down makes the car accelerate. The one on the left is the brake; moving your right foot over to press it slows or stops the car. The instructor repeatedly emphasized that mixing them up could lead to disaster, like mistaking the accelerator for the brake, which could cause instant loss of control. Now I’m used to switching my right foot, and it feels much easier. Automatic cars usually only have these two pedals, while manual cars also have a clutch in the middle, but the positions of the accelerator and brake remain the same. When practicing, it’s recommended to find an open area and try it several times to build muscle memory, avoid confusion, and prioritize safety.
With over 20 years of driving experience, I know it like the back of my hand: the right foot controls the accelerator, managing speed and engine power; the left foot operates the brake, responsible for slowing down and stopping. This design has its rationale – in emergencies, lifting the right foot off the accelerator allows immediate access to the brake, enabling quick reactions to prevent accidents. I remember mixing them up when I first started driving, but practice makes perfect. A reminder to new drivers: pay attention to the pedal positions to avoid panicking and hitting the wrong pedal at intersections. Automatic transmissions are simpler, while manual transmissions require coordination among three pedals, but the core principle remains the same.
