How many months must a driver be symptom-free if diagnosed with BPPV or peripheral vestibulopathy?

The regulation regarding drivers diagnosed with Benign Paroxysmal Positional Vertigo (BPPV) or peripheral vestibulopathy stipulates that the driver must be symptom-free for at least 2 months before being considered for certification. This requirement aligns with the understanding that two months is a sufficient period for recovery and to ensure that the driver does not experience reoccurring symptoms that could impair their ability to operate a commercial vehicle safely.

BPPV and vestibulopathy are conditions that can affect balance and coordination, essential skills for a commercial driver. If a driver has experienced these symptoms, allowing for a clear two-month window without any episodes helps to confirm that the condition is stable and not posing a risk to public safety.

The other choices suggest shorter or longer recovery periods that do not align with the established guidelines for these specific conditions. Therefore, the correct answer reflects the necessary period that ensures a driver has adequately recovered from their vestibular issues.
