When should the bus driver perform a safety check of the bus?

  1. When it is convenient to do so
  2. Never (the mechanic does it)
  3. Before the trip ✓
  4. During the trip

Answer: C. Before the trip

The bus driver should perform the safety check before the trip.

Why this is the answer

The handbook says NSC commercial vehicles must be inspected before they are used each day, and it calls these pre-trip inspections. For a bus, the pre-trip inspection section describes checking the bus before driving it. The driver also shares responsibility for making sure the inspection is done correctly; it is not something left to convenience or only to a mechanic. So the safety check belongs before the trip begins.

Why the other answers are wrong

Remember it

Think of the name: pre-trip means before you pull out.
