Final answer:
Alcohol, illegal drugs, prescription medications, and fatigue can all affect a person's driving by impairing coordination, reaction time, and cognitive function.
Step-by-step explanation:
Substances that can affect a person's driving include:
- Alcohol: Alcohol is a depressant that can impair coordination, reaction time, and overall cognitive function.
- Illegal drugs: Drugs like cocaine, amphetamines, and opioids can affect the central nervous system and impair driving abilities.
- Prescription medications: Certain medications, such as opioids, sedatives, and antihistamines, can cause drowsiness and hinder driving performance.
- Fatigue: Lack of sleep and fatigue can have similar effects on driving as alcohol or drugs, leading to decreased alertness and slower reaction times.
