Which One is the Accelerator and Which One is the Brake in a Car?

Car accelerator and brake positions vary depending on the vehicle type: In manual transmission cars, the accelerator and brake are located below the driver's cabin, arranged from left to right as clutch, brake, and accelerator; in automatic transmission cars, the accelerator and brake are also located below the driver's cabin, arranged from left to right as brake and accelerator. The brake system consists of a vacuum booster pump, master brake cylinder, wheel brake cylinders, brake pads, and brake discs. The accelerator pedal does not directly control the fuel injection volume. When the accelerator pedal is pressed, it directly controls the throttle valve, increasing the throttle opening. This allows more air to enter the engine, at which point the ECU commands the fuel injection system to inject more fuel, thereby increasing the engine speed and accelerating the vehicle.
I just got my driver's license a few days ago. The accelerator is the pedal on the right that makes the car surge forward when pressed—it's all about acceleration. The brake is on the left, and pressing it slows down or stops the car, ensuring stability and safety. During training, I often mixed them up—once while reversing, I almost hit a wall but managed to switch pedals in time. My instructor said the accelerator is the power source for forward movement, connected to the engine's intake, while the brake is the lifeline that prevents loss of control. In automatic cars, the accelerator is on the right and the brake on the left; with practice, a light tap of the foot naturally distinguishes them. As a beginner, practice more on suburban roads to get familiar with pedal feedback and build confidence, avoiding the danger of confusion on highways. For daily driving, gentle acceleration saves fuel, and anticipating stops early makes braking safer.
