What is blind spot detection?

Ebony Barker • October 1, 2024

Changing lanes when driving is the cause of many incidents, especially when travelling at high speeds. Even after checking your internal and external mirrors, it is still possible to miss a vehicle in your blind spot.


Blind spot detection is a type of advanced driver assistance system (ADAS), which typically operates via sensors located on a vehicle’s wing mirrors and bumpers. These sensors can detect if an obstruction such as a person or vehicle enters your blind spot, and will create a warning, such as flashing lights, steering wheel haptics or an audio alert.


In some vehicles, the warning will become louder and/or more obvious the closer the vehicle moves towards the obstruction. If the driver attempts a dangerous manoeuvre, some vehicles use automatic emergency steering and can even apply the brakes when needed, which is known as blind spot assist.
