Which behavior is most likely to indicate signs of a fatigued driver?

Maintaining a steady speed
Frequent lane changes
Drifting from your lane
Consistent use of turn signals

The correct answer is: Drifting from your lane

A fatigued driver is often unable to maintain focus and control, leading to lapses in attention that manifest as drifting from their lane. This behavior suggests a reduced awareness of the vehicle's positioning within the lane, which is a common consequence of fatigue. As fatigue sets in, the driver's reaction times slow down, and their ability to process visual and auditory information diminishes, resulting in swerving or failing to keep the vehicle within designated lane boundaries. Maintaining a steady speed, frequent lane changes, and consistent use of turn signals do not necessarily indicate fatigue. In fact, maintaining a steady speed can be a sign of attentiveness and control, while consistent use of turn signals reflects adherence to safe driving practices. Frequent lane changes may stem from other reasons, such as aggressive driving or navigating through traffic, rather than fatigue. Thus, drifting from the lane serves as the most direct indicator of a driver experiencing fatigue.
