Practice question

What are some hazards created by a mechanical breakdown?

  1. Noise pollution
  2. Smoke pollution
  3. Reduced visibility
  4. Increased speed

Answer: C — Reduced visibility

Mechanical breakdowns can create a variety of hazards, including reduced visibility due to malfunctioning lights or windshields. Options A, B, and D are incorrect because they do not pertain to the hazards of a mechanical breakdown. Noise pollution and smoke pollution may be caused by other factors, while increased speed is a result of the malfunction and not necessarily a hazard in and of itself.
