What are signs of fatigue in a driver?

Fatigue in drivers is characterized by a range of symptoms that indicate a decline in mental and physical alertness. Difficulty focusing eyes is a clear sign of fatigue because it shows that the driver is struggling to maintain attention on the road and the surrounding environment. When a driver is fatigued, their ability to concentrate diminishes, leading to impaired vision and slower reaction times, which can significantly increase the risk of accidents.

In contrast, signs such as increased alertness, enhanced energy levels, and frequent laughing typically indicate that a driver is well-rested and engaged. These states are contrary to what one would expect from a fatigued driver and suggest a good level of awareness and readiness to drive, making them unsuitable indicators of fatigue. Recognizing symptoms like difficulty focusing is crucial for ensuring road safety and for drivers to take appropriate measures, such as pulling over to rest or seeking a safe place to stop when experiencing fatigue.
