Is Sleep Apnea disqualifying?
Drivers should be disqualified until the diagnosis of sleep apnea has been ruled out or has been treated successfully. As a condition of continuing qualification, it is recommended that a CMV driver agree to continue uninterrupted therapy such as CPAP, etc. / monitoring and undergo objective testing as required.
A driver with a diagnosis of (probable) sleep apnea or a driver who has Excessive Daytime Somnolence(EDS) should be temporarily disqualified until the condition is either ruled out by objective testing or successfully treated.
Narcolepsy and sleep apnea account for about 70% of EDS. EDS lasting from a few days to a few weeks should not limit a driver’s ability in the long run. However, persistent or chronic sleep disorders causing EDS can be a significant risk to the driver and the public. The examiner should consider general certification criteria at the initial and follow-up examinations:
Severity and frequency of EDS
Presence or absence of warning of attacks
Possibility of sleep during driving
Degree of symptomatic relief with treatment
Compliance with treatment.
Can a driver who has a condition that causes excessive daytime sleepiness be certified?
Narcolepsy and sleep apnea account for about 70% of EDS. EDS lasting from a few days to a few weeks should not limit a driver’s ability in the long run. However, persistent or chronic sleep disorders causing EDS can be a significant risk to the driver and the public. While most of these diseases are usually disqualifying, The examiner should consider these general certification criteria at the initial and follow-up examinations:
Underlying condition causing the EDS.
Severity of and frequency of EDS
Presence or absence of warning of attacks
Possibility of sleep during driving
Degree of symptomatic relief with treatment
Compliance with treatment
After the initial evaluation, the examiner can decide if additional testing is required. Generally, drivers with excessive EDS need further evaluation to determine the cause and certification.
Can CMV drivers be qualified while being prescribed Provigil (Modafinil)?

These sleep disorders are narcolepsy, obstructive sleep apnea/hypopnea syndrome and shift work sleep disorders. Provigil has several concerning side effects such as chest pain, dizziness, difficulty breathing, heart palpitations, irregular and/or fast heartbeat, increased blood pressure, tremors or shaking movements, anxiety, nervousness, rapidly changing mood, problems with memory, blurred vision or other vision changes to name a few. Many drugs interact with Provigil which include over-the-counter medications, prescription medications, nutritional supplements, herbal products, alcohol containing beverages and caffeine. The use of Provigil needs careful supervision. Provigil may affect concentration, function or may hide signs that an individual is tired. It is recommended that until an individual knows how Provigil affects him/her, they may not drive, use machinery or do any activity that requires mental alertness.
Drivers being prescribed Provigil should not be qualified until they have been monitored closely for at least 6 weeks while taking Provigil. The treating physician and the Medical Examiner should agree that the Provigil is effective in preventing daytime somnolence and document that no untoward side effects are present. Commercial motor vehicle drivers taking Provigil should be re-certified annually.
