Understanding Cars

What is blind-spot detection?
Blind-spot detection, also known as lane-change assist, alerts drivers to cars traveling alongside in their over-the-shoulder blind spots. It supplements the coverage of your car’s rear- and side-view mirrors. Blind-spot detection is not designed to replace vigilance to what’s in your mirrors followed by a good-old fashioned glance over your shoulder before you change lanes. It is, after all, lane-change assistance.
