When pulling away from the curb in a bus, you should

  1. make sure that the rear of your bus does not swing over the sidewalk.
  2. make sure that your passengers are not moving around.
  3. make sure that traffic is clear.
  4. do all of the above. ✓

Answer: D. do all of the above.

You should do all of the above: check that traffic is clear, make sure passengers are not moving around, and keep the rear of the bus from swinging over the sidewalk.

Why this is the answer

The handbook says that before you leave the curb, you must look in the side mirror and over your shoulder to confirm traffic is clear, and you should not depend on the side mirrors alone. It also says to make sure passengers are not moving around, to signal, and to check over your shoulder again. Finally, it warns that the back of the bus must not swing over the sidewalk, because it could hit pedestrians, cyclists, poles, or sign posts near the curb. All three checks belong together, so the combined answer is correct.

Why the other answers are wrong

Remember it

Before leaving the curb, run a quick scan: traffic, passengers, and the bus's rear swing.
