Fatigue poses a threat to safe driving by causing ______.

  1. Longer reaction time

  2. Increased confidence

  3. Preoccupation

  4. Unavoidable collisions

The correct answer is: Longer reaction time

Fatigue affects a driver's ability to respond swiftly and accurately to changing road conditions. When a person is fatigued, their cognitive functions, including reaction time, are impaired. This means that they are less able to respond to sudden obstacles, traffic signals, or changes in the behavior of other drivers. Longer reaction times due to fatigue can lead to an increased risk of accidents. For instance, if a driver is drowsy, they may take longer to hit the brakes when a pedestrian suddenly steps into the road. This delay in response can turn a potentially avoidable incident into a serious collision. It's crucial for drivers to recognize the effects of fatigue and to ensure they are well-rested before getting behind the wheel to maintain optimal reaction times and overall driving safety.
