What is the third step in the lane changing process?

The third step in the lane-changing process is to check over your left or right shoulder. This action is crucial because it allows you to visually confirm that there are no vehicles or obstacles in your blind spot before making the lane change. Relying solely on mirrors can be insufficient, as they do not cover areas behind and beside your vehicle that are not visible in the rearview or side mirrors.

By physically checking over your shoulder, you enhance your awareness of the surrounding traffic and ensure a safer maneuver. This step comes after you've signaled your intent to change lanes and before you actually change the lane, reinforcing the importance of a thorough check of the driving environment to avoid potential accidents. Following this systematic approach helps maintain safety for yourself and other road users when changing lanes.
