According to the emergency equipment check, what must be in good working condition?

• A. Only emergency lights.
• B. Only radios.
• C. None.
• D. All emergency equipment and the radio.

Answer: (D)

The key idea is that vehicle safety checks require every piece of emergency gear to be operable, not just a part of it. When you’re performing the emergency equipment check, you verify that all emergency equipment and the radio are in good working condition. This comprehensive requirement ensures you can rely on both illumination, signaling, safety tools, and communication during emergencies.

If you only check one item, like emergency lights, you might miss a radio or other essential gear that could be needed to coordinate a response. Conversely, checking only the radio ignores the other equipment that must function properly. Saying none would be in good condition contradicts the purpose of the check, which is to confirm readiness.

So, all emergency equipment and the radio must be in good working condition.
