What is a Blind-Spot Monitor?
All vehicles have blind spots. These are areas or zones on either side of a car that a driver cannot see when looking into the rearview or side-view mirrors. Blind spots are why a driver should always turn their head and check for cars before changing lanes. To help drivers become more aware of objects in these blind spots, many car companies offer vehicles with blind-spot monitoring (BSM), also known as blind-spot warning, blind-spot detection, or blind-spot information system, depending on the automaker.
