Question: 1 / 400

What is the main effect of driving under the influence of alcohol?

Decreased reaction time and impaired judgment

Driving under the influence of alcohol significantly impacts a person's ability to operate a vehicle safely. The main effect includes decreased reaction time and impaired judgment. Alcohol acts as a depressant on the central nervous system, which slows down cognitive processes and physical responses. As a driver's reaction time increases, their ability to respond quickly to sudden changes on the road, like obstacles or traffic signals, diminishes.

Impaired judgment means that individuals are less capable of making sound decisions. They might underestimate risks or overestimate their capabilities, which can lead to dangerous driving behaviors. This combination of slowed reactions and poor decision-making increases the likelihood of accidents. Understanding these effects emphasizes the critical importance of avoiding driving after consuming alcohol to ensure safety for oneself and others on the road.
