What is bsm in a car?

BSM stands for Blind Spot Monitoring, a vehicle feature that uses sensors to detect and alert drivers of vehicles in their blind spots. This technology helps drivers avoid potential collisions while changing lanes or merging onto highways. When a vehicle enters the blind spot, the system typically activates a warning light or sound in the side mirrors or dashboard to notify the driver. Some BSM systems also provide additional features such as rear cross-traffic alert, which warns drivers of approaching vehicles when backing out of parking spaces. Overall, BSM helps improve safety and reduce the risk of accidents on the road.
