Commercial Drivers License Exam Prep

Answer: C - The cumulative effect of not getting enough sleep is known as sleep debt. Commercial drivers, because of the length of many hauls, should always be aware of this condition and its symptoms. Sleep debt happens when drivers do not get the sleep that they need on a daily basis. Insomnia is not the same as sleep debt. Sleep apnea may be a cause of sleep debt but it, too, is not the same. The only way to rid the body of sleep debt is to get some sleep! Most individuals need between seven and eight hours of sleep per day.
