What must a driver do if a required emergency exit, signaling device, or piece of emergency equipment on the bus is missing or not working?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

Not drive the bus until the defect is repaired, because these items are required for passenger safety

  1. A Cover the broken item with tape and continue
  2. B Drive anyway if passengers are waiting
  3. C Only fix it at the end of the route
  4. D Not drive the bus until the defect is repaired, because these items are required for passenger safety

Why this is the answer

Emergency exits, interior lighting, passenger signaling devices, and required emergency equipment (such as fire extinguishers, spare fuses where applicable, and warning devices) are essential to passenger safety. If any of these are missing, broken, or not functioning, the bus must not be driven until the problem is fixed. The manual is explicit that a driver may not transport passengers in a bus with these defects. Discovering and correcting such issues is exactly why the pre-trip inspection exists; skipping it or driving despite a known defect puts passengers at risk and is a violation.
