BSM stands for “blindspot monitoring” in general, though some manufacturers have specific names for their blindspot monitoring system. These systems will detect if a vehicle is in your blind spot, then notify you—usually via a warning light on your rearview mirror or a small beep, depending on the manufacturer.
Blindspot monitoring uses radar sensors or cameras to detect the presence of vehicles in your blindspot. BSM is considered an active safety feature and is often bundled with other active safety features, like rear cross-traffic alert or lane-keep assist.
Blindspot monitoring has been proven to reduce the number and severity of lane-change collisions. Even if your vehicle has blind spot monitoring, though, you should still make visual checks rather than relying fully on the BSM.
Safety features like BSM can not only keep you safe, but they may also earn you discounts on your car insurance. To find the most affordable coverage—or to just find the best deals and discounts—use the
