Of course, anyone could get behind the wheel when they are really too tired to drive, but certain groups other than long-haul truck drivers tend to do so more often, which increases your risk of harm if you encounter one of them:
Shift workers, including those who work the night shift
Shift workers who work rotating shifts
People who work no less than 60 hours per week
Those who suffer from undiagnosed or untreated sleep disorders, such as obstructive sleep apnea
People who travel for business and may be jet lagged or drive long hours
Young people, particularly men under the age of 26
