What mental condition can contribute to drowsy driving?

Highway hypnosis is a mental state that can occur during long, monotonous drives, where a driver can become so focused on the road that they may enter a trance-like condition. This can lead to a decreased level of alertness, making it difficult for the driver to remain aware of their surroundings or react to changes in the driving environment. As a result, highway hypnosis can significantly contribute to drowsy driving because the driver may fail to notice signs of fatigue or changes in traffic conditions, potentially resulting in dangerous driving situations. Understanding this condition is crucial for drivers as it emphasizes the importance of taking breaks and staying aware of one's mental state while on the road.
