Which of the following is a consequence of driving while fatigued?

Answer: B — Decreased awareness

Driving while fatigued can significantly impair a person's cognitive and physical abilities, leading to a decreased awareness of their surroundings. Fatigue affects how effectively a driver can process information and respond to the tasks of driving. When a driver is not fully alert, their ability to recognize traffic signals, pedestrians, or other vehicles diminishes, which increases the risk of accidents. In contrast, increased reaction time and improved decision-making would typically be characteristics of a well-rested driver. Enhanced concentration, too, is not achievable when a person is fatigued; rather, fatigue leads to distractions and a lack of focus, making it more difficult to maintain attention on the road. Thus, decreased awareness is a direct and serious consequence of driving while fatigued, highlighting the importance of being well-rested before getting behind the wheel.
