Which is the Brake and Which is the Accelerator in an Automatic Transmission?

In an automatic transmission, the left pedal is the brake and the right pedal is the accelerator. Automatic transmission vehicles do not require the driver to manually shift gears, so there is no clutch pedal—only the brake and accelerator pedals. When driving an automatic car, only the right foot is used; the left foot remains idle. It is highly unsafe to rest the left foot on the brake pedal while driving. If the left foot is on the brake pedal, the right foot must lift off the accelerator when braking, leaving it in a suspended state. This increases the risk of accidentally pressing both pedals simultaneously, which can be dangerous. Lifting the right foot off the accelerator before pressing the brake is a safer approach. Moreover, in sudden emergencies, a panicked driver might instinctively press the brake with the left foot while keeping the right foot on the accelerator, potentially damaging the transmission, causing loss of vehicle control, and leading to severe consequences.
In an automatic transmission car, my driving instructor told me that the leftmost pedal is the accelerator pedal, which makes the car speed up when pressed; the one on the right is the brake pedal, which slows down or completely stops the car when pressed. Beginners are most prone to accidents by mixing up the pedals. I remember being so nervous on my first drive that I almost pressed the wrong one. Later, I deliberately practiced: placing my left foot on the dead pedal and using only my right foot to operate, as the left foot's role in managing the clutch is unnecessary in an automatic. Before forming the habit, it's good to practice in an empty parking lot to get a feel for lightly pressing the accelerator and firmly pressing the brake. The pedal design follows a standard layout of light on the left and heavy on the right. The positions are similar in different cars, but safety comes first—don't be careless when driving fast.
After driving automatic transmission cars for over a decade, I've long been accustomed to the accelerator being on the left and the brake on the right. A gentle press on the accelerator ensures smooth acceleration, while braking requires decisive action – stomping hard during emergency stops. During daily driving, my right foot moves between both pedals, keeping the left foot uninvolved to prevent misoperation. I once saw a friend nearly get into trouble when switching to a new car without noticing pedal positions, so I always check pedal orientation before driving. Whether it's a sedan or SUV, automatic transmission designs follow this same rule – remembering pedal positions is fundamental to safety.
