These three pedals are limited to manual transmission cars, because automatic transmission cars do not need clutch pedals, so automatic transmission cars only have brake pedals and accelerator pedals.
These three pedals have different names, so their functions are different. The clutch pedal is used to shift gears, the brake pedal is used to slow down or stop, and the accelerator pedal is also called the accelerator pedal to control the vehicle speed. Beginners must distinguish the functions of these three pedals when they are new to driving knowledge, and they should not be confused.
When driving a motor vehicle, the left foot is generally responsible for controlling the clutch pedal, and the right foot is responsible for controlling the brake pedal and the accelerator pedal. It should be noted that when driving a motor vehicle on the road, if you don't need to step on the clutch pedal, you must not put your left foot on it, because if you put your left foot on the clutch pedal for a long time, you may touch it by mistake, which is very dangerous for the moving car.
