Making the Business Case for Safety Innovation with In-Cab Fatigue Monitoring

A study by the AAA Foundation for Traffic Safety estimated that almost 18% of all fatal crashes between 2017–2021 involved a drowsy driver. In-cab fatigue monitoring systems reduce this risk by using advanced sensors and analytics to detect signs of fatigue, such as gaze direction, blinking patterns and head movements. When a driver exhibits these signs, the system can immediately alert them via visual, audible and haptic feedback and notify supervisors, providing a critical cue for the driver to refocus or take a break. These data can also be used to identify high-risk patterns, optimize shift scheduling and inform fatigue-management strategies.

Night Shift

According to the National Highway Traffic Safety Administration, crashes resulting from drowsy driving occur most frequently between the hours of midnight and 6 a.m., or in the late afternoon. Night shift drivers are especially vulnerable due to disruptions to their circadian rhythm—the body’s internal clock that regulates sleep, wakefulness and other physiological processes. In-cab fatigue monitoring can proactively detect early signs of drowsiness and prompt timely interventions, reducing risk during these high-risk periods.
