Blind spot monitoring is a safety feature in vehicles designed to help drivers be aware of their surroundings. It uses sensors to detect vehicles in the blind spots—areas that are not visible in the side mirrors. When another vehicle is detected, the system typically alerts the driver with a visual or audible warning. This technology enhances driving safety, especially during lane changes. By providing real-time information about nearby vehicles, blind spot monitoring helps reduce the risk of accidents and improves overall road awareness for drivers.
