Which statement is false concerning hearing requirements of commercial drivers?

The statement regarding hearing aids not being worn during the forced whisper test is accurate, which is why it is the correct answer to identify as false. Hearing aids may significantly enhance a person's ability to hear, providing an unfair advantage during the assessment. The forced whisper test is designed to evaluate the driver's baseline hearing ability without compensatory devices, ensuring that only their natural hearing is being assessed.

As for the other statements, they align with the established guidelines for hearing requirements in commercial drivers. Performing either the forced whisper test or audiometry test first is permissible, allowing flexibility in the testing process. The forced whisper test criteria also hold true; a driver is considered to have passed if they can perceive the whisper from at least 5 feet away in one ear. If a driver does not pass the first test, conducting both tests is necessary to fully establish their hearing capabilities, ensuring comprehensive evaluation. This approach reinforces safety, as effective communication is critical for commercial drivers.
