The boys told their mother, Kelly Harper, that they were forced to walk home after their bus driver told them to get off the bus while they were heading along Elevation Road in Four Oaks.
Harper says it goes against common sense and she wants that school bus driver fired.
The children walked along the edge of the rural road, which has a speed limit of 55 miles per hour, to their home about a mile away.
Harper says the kids realized they got on the wrong bus on Monday. They told the bus driver and the driver's response was that she didn't have time to turn around. So, she let them off the bus.
The children's father happened to be driving by and spotted the boys and picked them up off the edge of the road.
"You can't give me an excuse that I would take," said Harper. "As a parent, I'm not going to take your excuse, especially if you have a phone and then not only you have a phone. I'm pretty sure nowadays, it's 2013. You have a cell phone on hands. You could have pulled that bus over to the side of the road and you could have called somebody."
The superintendent of the Johnston County School District says he is taking this incident seriously and he strives for all students to arrive to and from school safely.
Transportation services and administration is now investigating, but would not comment on whether the driver would be fired.
