Question restatement: What was the result of a beeping system designed to keep truck drivers awake?
Option 1: 'Drivers stayed awake while driving' — This would imply that the beeping system successfully kept drivers alert throughout driving. However, the historical design of such beeping devices was often intended to prompt a break rather than enforce constant wakefulness, and driver fatigue remains a complex issue that this simplistic mechanism typically failed to guarantee. Therefore this option overstates the effectiveness of a single alert in maintaining wakefulness.
Option 2: 'Drivers would pull over to take naps after the beep' — This option reflects a known outcome of fatigue management systems in some contexts: the beep signals a mandated or advised rest period, causing drivers to stop and nap. This aligns with safety strategies that encourage periodic rest breaks in response to fatigue indicators, making this a plausible and historically documented result.
Option 3: 'Drivers learned to sleep with their eyes open' — This is an exaggerated and biologically implausible claim. Humans cannot maintain sleep while awake in a functional sense, and a beeping alert would not teach or enable such a paradoxical behavior; this option is not consistent with how sleep and wakefulness operate.
Overall, the reasoning supports that the intended function of a beeping rest-alert system is to prompt a break, not to guarantee continuous awake driving, nor to induce an impossible mode of sleep. The most accurate interpretation among the choices is that the beeping led drivers to pull over to take naps after the beep.
