How does drug use affect a person's driving ability?

Drug use significantly affects a person's driving ability by impairing various essential functions necessary for safe driving. When an individual consumes drugs, they often experience a decline in judgment, which can lead to poor decision-making on the road—such as failing to recognize hazardous situations or misjudging their own driving capabilities.

In addition to judgment, coordination is crucial for executing complex driving tasks, such as steering, navigating turns, and maintaining lane discipline. Drugs can disrupt the neuromuscular pathways required for these actions, resulting in clumsiness or an inability to control the vehicle properly.

Furthermore, reaction time is vital for responding quickly to unexpected events, such as sudden stops or obstacles. Impaired reaction time due to drug use can lead to accidents because the driver may not be able to respond swiftly enough to avoid danger.

Therefore, the correct answer reflects the comprehensive impact that drugs have on key driving abilities, emphasizing how they can compromise overall driving safety.
