How should you check your blind spots?

To effectively check your blind spots, the best practice is to look over your shoulder and check your mirrors just before changing lanes. This method ensures that you have a comprehensive view of the area around your vehicle that may not be visible in your mirrors alone.

When you glance over your shoulder, you are able to see vehicles that might be in the blind spot, which lies outside the view provided by your side and rear-view mirrors. This is important for safe lane changes, as it allows you to make sure that there is no one in your blind spot who could potentially collide with you if you were to change lanes without checking.

Relying solely on mirrors or vehicle sensors can lead to a false sense of security, as these tools may not cover every angle and could miss vehicles that are directly beside you or just out of view. Hearing a sound before changing lanes also does not provide the visual confirmation needed to ensure the lane is clear. Thus, actively checking your blind spots visually right before making a lane change is essential to maintaining safety on the road.
