What is the effect of alcohol on driving performance?

Alcohol has a significant adverse effect on driving performance, primarily by decreasing motor skills and judgment. When alcohol is consumed, it affects the central nervous system, impairing cognitive functions crucial for safe driving.

The motor skills necessary for controlling a vehicle, such as steering, braking, and accelerating, are hindered as alcohol impairs coordination and balance. Additionally, alcohol consumption leads to poor judgment, which can affect decision-making while driving, such as misinterpreting traffic signals, failing to react appropriately to sudden changes in road conditions, or not recognizing hazards.

These impairments collectively increase the risk of accidents, making it essential for drivers to understand the dangers of alcohol consumption before operating a vehicle.
