This category rarely gets studied as seriously as alcohol does, even though FTT treats fatigue as a comparably serious risk factor.
Here is one worth locking in:
If you start feeling drowsy on a long drive, what is the correct action according to the FTT, keep going since you're almost there, or stop immediately?
The correct answer is to stop as soon as safely possible and rest, continuing "since you're almost there" is treated as one of the classic wrong answers, since fatigue-related reaction time loss can happen suddenly and without full awareness. Opening a window or turning up music is not considered a substitute for actual rest.
Beyond fatigue, this category also covers reduced visibility and glare management during night driving.
Your turn. If there is a fatigue or night driving scenario you keep mixing up, post it here. If you know the answer to someone else's, help them out.
