Consuming alcohol slows a driver's central nervous system response, increasing reaction time even when performing simple motor actions such as stepping on the brake pedal.
Answer: Answer
Answer
The statement is true because alcohol depresses central nervous system functions, delaying motor transmission and increasing brake reaction time regardless of how simple or automatic the physical movement may seem.
The statement is correct because alcohol depresses central nervous system activity. This biological slowing directly retards neural messaging between the brain and body muscles, resulting in measurably longer reaction times for simple motor actions like braking.
