Question: You are performing a pre-operational inspection on a telehandler and notice that the horn is not functioning. What is the required action according to safety standards?

Answer options:

• Use hand signals exclusively to communicate with co-workers.
• Continue operation, but limit work to areas with low pedestrian traffic. ✅ Red-tag the machine and remove it from service until the horn is repaired.
• Attempt to troubleshoot the electrical connection to the horn before reporting.

Correct answer: Red-tag the machine and remove it from service until the horn is repaired.

Explanation: A non-functioning horn is a safety defect that impairs the operator's ability to alert others, posing a significant hazard. The machine must be red-tagged and removed from service until the horn is repaired, as per safety regulations. Substituting with hand signals or operating in limited areas is not an acceptable alternative to a critical safety device.
