How does drowsy driving affect crash risk?

Drowsy driving significantly increases crash risk due to impaired processing. When a driver is fatigued, their cognitive functions, such as attention, reaction time, and decision-making abilities, are compromised. This impairment resembles the effects of alcohol intoxication, leading to difficulties in maintaining focus on the road, recognizing hazards, and responding swiftly to traffic signals and other drivers.

Drivers who are drowsy may find it harder to accurately gauge their speed and the distance to other vehicles, making it challenging to execute safe maneuvers. They are also more likely to experience lapses in attention, which can result in drifting out of lanes or failing to notice traffic changes.

Understanding the detrimental effects of drowsiness on driving capabilities emphasizes the importance of being well-rested before getting behind the wheel to ensure maximum safety for oneself and others on the road.
