If a CMV driver has mild intermittent asthma that is well-controlled, what additional certification is required?

For a commercial motor vehicle (CMV) driver with mild intermittent asthma that is well-controlled, no additional documentation is required beyond the standard medical certification process. Mild intermittent asthma typically does not significantly impact a driver's ability to perform safely, especially if symptoms are infrequent and well-managed through treatment or management strategies.

Regulations set forth by the Federal Motor Carrier Safety Administration (FMCSA) outline that drivers with well-controlled conditions do not need extra documentation or certification from specialists, unlike those with more severe manifestations of asthma or other respiratory conditions that could impair driving capabilities. In general, the medical examiner's assessment will focus on the driver's overall health, including their respiratory function, but if the asthma is managed effectively, it does not necessitate further requirements such as a specific asthma management plan, annual pulmonary function testing, or certification from a pulmonary specialist. Hence, the conclusion is that no additional documentation is necessary for such a driver.
