What is the risk of driving after consuming just one drink?

Driving after consuming just one drink can indeed impair driving ability significantly. Alcohol has a direct effect on the central nervous system, even in small quantities. It can lead to reduced coordination, slower reaction times, and impaired judgment. These impairments can increase the risk of accidents, as the driver may be less able to respond effectively to sudden changes in the driving environment, such as obstacles or the actions of other drivers.

The other options suggest that one drink has no effect on driving ability or that only larger quantities matter, which does not reflect the reality of how alcohol impacts the body. Additionally, some may believe that consuming alcohol makes them more cautious; however, this is a common misconception. Alcohol can distort perception, leading drivers to underestimate risks or overestimate their capabilities. Therefore, even one drink can pose a risk while driving, making it critical to remain aware of one's consumption before getting behind the wheel.
