Which action is acceptable when changing lanes?

The correct response emphasizes a safe and responsible approach to changing lanes. Signaling your intention to change lanes is critical because it communicates your plans to other drivers, helping to prevent accidents and misunderstandings on the road.

Looking over your shoulder before changing lanes is a crucial step, as it allows you to check for blind spots where other vehicles may not be visible through your mirrors. This combination of signaling and looking ensures that you are aware of your surroundings and that you are taking the necessary precautions to change lanes safely.

Together, these actions form a standard practice for lane changes that promotes safety on the road, consistent with the regulations governing junior operators in Massachusetts. Following this procedure reduces the likelihood of collisions and reinforces the importance of attentive driving.
