As Blood Alcohol Concentration (BAC) increases, what happens to a driver?

As Blood Alcohol Concentration (BAC) increases, judgment and self-control diminish. Alcohol acts as a depressant to the central nervous system, which can impair cognitive functions, affect decision-making processes, and reduce an individual's ability to evaluate situations accurately. This impairment can lead to engaging in risky behaviors, failing to recognize hazards, and making poor choices while driving.

In contrast, as BAC increases, vision tends to worsen, reflexes slow down, and the ability to focus declines. Each of these impacts contributes to an increased risk of accidents and unsafe driving conditions. Thus, it's crucial for drivers to remain aware of the effects of alcohol on their abilities to operate a vehicle safely.
