How does alcohol affect your driving ability?

Alcohol significantly impairs several key abilities that are critical for safe driving, making the second choice the correct answer. When consumed, alcohol affects the brain's functioning, leading to decreased judgment abilities, which can result in poor decision-making on the road, such as misjudging distances or speeds. It also negatively impacts coordination, making it difficult for a driver to control the vehicle effectively—this includes steering, braking, and obeying traffic signals.

Additionally, alcohol slows down reaction times, meaning that a driver may not respond quickly enough to sudden changes in the driving environment, like a pedestrian suddenly stepping into the road or another vehicle making an unexpected maneuver. These impairments cumulatively increase the risk of accidents and endanger not only the driver but also passengers and other road users.

The other options are misleading: the first choice suggests alcohol improves coordination, which is contrary to scientific evidence, as the opposite effect occurs. The option stating there is no effect on driving inaccurately downplays the severe impact of alcohol on driving abilities. Finally, the notion that alcohol enhances reaction speed is incorrect, as it actually slows down reactions, making driving under the influence extremely dangerous.
