Should examiners advise hearing aid users to carry spare batteries?

Advising hearing aid users to carry spare batteries is advisable because a hearing aid relies heavily on a functioning battery for optimal performance. Without adequate power, a hearing aid will not work, significantly impacting the user's ability to hear and communicate, which is critical for safe driving and overall wellbeing. Carrying spare batteries ensures that users are prepared for situations where their current batteries may run low or fail unexpectedly, thus enhancing their safety and reliability while on the road. This practice aligns with the goal of FMCSA regulations, which prioritize the health and safety of commercial drivers. Maintaining awareness and preparedness around hearing aid functionality is essential for those who depend on them.
