A Pre-Collision System is a safety feature in vehicles designed to help prevent accidents. It uses sensors and cameras to detect obstacles, such as other vehicles or pedestrians, in the car's path. If the system identifies a potential collision, it alerts the driver and may automatically apply the brakes to reduce the impact or avoid the crash altogether. This technology is part of advanced driver-assistance systems (ADAS) and is commonly found in many modern cars, including those from manufacturers like Toyota and Honda. By enhancing situational awareness, the Pre-Collision System aims to improve road safety for everyone.
