How can drowsiness impact driver inattention?

Drowsiness significantly decreases awareness, which is critical for safe driving. When a driver is tired, their ability to pay attention to the road, anticipate potential hazards, and react effectively to sudden changes in traffic conditions is impaired. This lack of alertness can lead to slower reaction times, missed signs, and an overall reduced ability to perform the complex tasks required for operating a vehicle safely. As a result, drowsiness can be just as dangerous as distractions, as a driver may not be fully engaged or able to process information and respond appropriately, increasing the risk of accidents.
