Blind-spot monitoring systems are safety features in vehicles designed to help drivers detect vehicles in their blind spots. These systems use sensors, typically located in the rear corners of the car, to monitor the areas that are not visible in the side mirrors. When another vehicle enters this zone, the system alerts the driver, often through visual or audible warnings. These systems enhance road safety by reducing the risk of collisions during lane changes. They are particularly useful in larger vehicles, where blind spots can be more significant. Many modern cars, including those from brands like Toyota and Ford, now come equipped with this technology.
