Blind Spot Detection is a safety feature in vehicles designed to help drivers be aware of areas they cannot see while driving. It typically uses sensors located on the sides of the car to monitor adjacent lanes. When another vehicle enters the driver's blind spot, a warning light illuminates on the side mirror, alerting the driver to the potential danger. This technology enhances road safety by reducing the risk of collisions during lane changes. Some systems may also provide audible alerts or even automatic steering assistance to help prevent accidents. Overall, Blind Spot Detection contributes to safer driving experiences.
