Truck drivers must have adequate restful sleep to be safe and effective at their job. According to the FMCSA says that up to 28 percent of all U.S. CDL holders have sleep apnea.
Sleep apnea is a danger to everyone, truck driver and others alike. Sleep apnea is a condition where the upper airway narrows or closes during sleep. This causes a person to wake repeatedly during his/her sleep, which makes their sleep not restful.
