Truck drivers play a critical role in ensuring the smooth flow of goods across the country, often spending long hours on the road. However, the demanding nature of the job can sometimes lead to health conditions that compromise safety—both for the driver and other road users. One such condition is sleep apnea, a disorder that affects a person's ability to breathe properly while sleeping. The Federal Motor Carrier Safety Administration (FMCSA) requires drivers who show risk factors for sleep apnea to undergo a sleep apnea test as part of their DOT physical.
