What is a car blind spot sensor?

A car blind spot sensor is a safety feature that detects vehicles in a driver's blind spots, typically located on the sides of the vehicle. It uses radar or cameras to monitor the area alongside and behind the car, alerting the driver through visual or audible warnings when another vehicle is present. This technology helps prevent lane-change accidents and enhances overall driving safety. Many modern vehicles come equipped with this feature as part of advanced driver-assistance systems (ADAS).
