Question: 1 / 400

What is a common effect of fatigue on safe driving?

Increased alertness

Improved reaction time

Decreased concentration

Fatigue significantly impacts a driver's ability to concentrate on the task at hand. When a person is fatigued, their brain struggles to maintain focus, often leading to diminished attention span and an inability to process information quickly and accurately. This decrease in concentration can result in slower reactions to important driving situations, such as changes in traffic conditions or unexpected obstacles.

Additionally, reduced concentration can lead to lapses in judgment, making it more difficult for a fatigued driver to assess risks and make safe driving decisions. It becomes challenging for them to stay engaged with the driving environment, increasing the likelihood of accidents. Recognizing this effect underscores the importance of rest and vigilance while driving to ensure safety on the roads.
