What is Blind Spot Monitoring System

Blind-spot monitoring system is a safety driving system with sensors mounted on the side mirrors and rear bumper to detect vehicles, objects, or other obstacles in the adjacent lanes. Upon detecting an obstacle, the sensors will send an audible or visual warning to your vehicle’s dashboard, enabling you to take appropriate action. Depending on the type of vehicle, cameras can be installed to complement the sensors, making the blind-spot monitoring system more effective.

With the advancement and availability of tech, you can find blind spot monitoring systems across the market, including luxury cars, subcompact vehicles, and massive trucks.

Blind-spot monitoring systems can also be integrated with rear cross-traffic alert features to help drivers detect vehicles, objects, or obstacles when reversing their vehicles out of parking spots.

How Blind-Spot Monitoring System Works?


Blind-Spot monitoring systems (BSM) are the most common driver aid technologies you’d expect to find in many mid-tier or budget models. BSM features ultrasonic sensors on the car’s side mirrors and rear bumper to detect obstacles, objects, or vehicles in your blind spots. Most Blind spot monitoring systems will alert the driver by sending an audible or visual warning near the side mirror or on either side of the vehicle.

Upon detecting an obstacle, you’ll get an audible beep or tone warning you about changing lanes when you activate your turn signal. In the process, you’ll be able to look twice before changing lanes.

Most basic systems are designed to alert you whenever a car is in your blind spot, while more sophisticated ones often warn you before a car gets to your blind spot. Even more, some Blind spot monitoring systems feature Lane Change Assist, which monitors the speed of oncoming vehicles and obstacles up to a length of three to five cars. This helps drivers to predict the situation on the road, enabling them to avoid Carshes on the road.

Blind- spot monitoring systems are designed to help drivers predict vehicles, obstacles, or objects in their blind spots. However, drivers shouldn’t solely rely on them because they may not be effective during the night or in bad weather.
