General Knowledge · Night Driving and Driver Fatigue
Under 49 CFR 383.111(a)(20), which of the following is one of the required fatigue-and-awareness practices that CDL knowledge tests must cover?
Explanation
Federal regulation requires CDL knowledge tests to cover what to do when becoming ill while driving, alongside being prepared to drive, avoiding fatigue while driving, and what to do when feeling sleepy, under 49 CFR 383.111(a)(20). These four practices are grouped together because fatigue and sudden illness both impair a driver's ability to control the vehicle safely, so the required-knowledge topic treats staying alert and fit to drive as one connected area. The other options fail for a shared reason: hours-of-service logging, bill-of-lading paperwork, and checking a fuel gauge are all real trucking tasks, but none of them belong to this specific fatigue-and-awareness required-knowledge list.
