Sleep apnea is a growing concern in the trucking industry, as untreated sleep apnea symptoms can significantly impact a driver's performance and safety on the road. Often, people equate impaired driving with driving under the influence of drugs or alcohol. However, another form of impaired driving, equally hazardous and unrelated to the consumption of illicit substances, exists. Known as drowsy driving, this form of impairment poses a distinct threat to commercial motor vehicle (CMV) operators, their companies, and others sharing the road.
