Blind spot monitors are safety features in vehicles designed to help drivers detect vehicles in their blind spots. These systems typically use sensors located on the sides of the car to monitor adjacent lanes. When another vehicle enters the blind spot, a warning light illuminates on the side mirror, alerting the driver to the potential danger. In addition to visual alerts, some blind spot monitors may also provide audible warnings or vibrations in the steering wheel. This technology enhances overall road safety by reducing the likelihood of accidents during lane changes, making it a valuable addition to modern vehicles like SUVs and sedans.
