How does fatigue affect driving?

It enhances reaction time
It has no effect on driving
It increases awareness
It decreases reaction time and awareness

The correct answer is: It decreases reaction time and awareness

Fatigue significantly impairs a driver's ability to operate a vehicle safely. It decreases reaction time, meaning that the driver may not respond quickly enough to sudden changes in the driving environment, such as the actions of other drivers, pedestrians, or road hazards. At the same time, fatigue also decreases awareness, making it harder for the driver to remain focused on the road and to notice important details. When a driver is tired, their ability to make sound judgments is compromised, increasing the likelihood of accidents. In contrast, enhancement of reaction time or increase in awareness, as suggested in the other options, is not consistent with the effects of fatigue. Fatigue generally leads to slower responses and reduced situational awareness, elevating the risks associated with driving.
