Which of the following is an impact of chronic fatigue on CMV drivers?

Chronic fatigue significantly impacts the performance and safety of CMV drivers. When drivers experience fatigue, their cognitive functions, reaction times, and overall driving ability are impaired. This leads to a heightened risk of accidents and safety concerns because fatigued drivers may struggle to maintain attention, make quick decisions, and respond effectively to road conditions. The detrimental effects of fatigue can manifest as slower reaction times or lapses in judgment, both of which are critical in operating a commercial motor vehicle safely. Therefore, recognizing chronic fatigue as a serious hazard that can compromise both the driver's safety and the safety of others on the road is essential for preventing accidents and promoting safer driving practices.

Other options suggest situations that mischaracterize the effects of fatigue. Increased focus and concentration, improved decision-making abilities, and a belief that regulations alone can mitigate impacts overlook the fundamental hazards posed by chronic fatigue.
