Explanation:

In a position - time graph, a horizontal line means the position is not changing (object is at rest). An upward - sloping line means the object is moving away from the reference point (as position is increasing with time). Another horizontal line after the sloping line means the object has stopped again.

It stands still, moves away from the reference point, then stops again.
