Which of these is a good rule for backing a straight bus?
"When you have to back, here are a few simple safety rules: Back and turn toward the driver’s side whenever possible. Use a helper when you can. There are blind spots you can’t see. That’s why a helper is important. The helper should stand near the back of your vehicle where you can see the helper. Before you begin backing, work out a set of hand signals that you both understand. Agree on a signal for \"stop.\""
