A drunken person should not drive a vehicle because alcohol

Options

A. Increses reaction time
B. Affects coordination of body parts, alertness and judgement
C. Causes rashness and carelessness
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding Alcohol's Effect on the Central Nervous System**:
- Alcohol is a depressant that affects the central nervous system, primarily the brain. It alters brain function and impairs cognitive abilities.

2. **Impact on the Brain**:
- When consumed, alcohol first affects the cerebrum, which is responsible for higher brain functions such as judgment, self-control, and willpower. This impairment leads to poor decision-making.

3. **Loss of Judgment and Self-Control**:
- A drunken person loses their ability to make sound judgments and control their actions. This can lead to risky behaviors, such as driving under the influence.

4. **Coordination and Motor Skills**:
- Alcohol also affects the cerebellum, which is responsible for coordination and balance. This results in physical symptoms like slurred speech, blurred vision, and difficulty in motor control.

5. **Inability to Judge Distances**:
- One of the critical impairments caused by alcohol is the inability to accurately judge distances. This is particularly dangerous when driving, as it can lead to accidents.

6. **Increased Reaction Time**:
- Alcohol consumption increases reaction time, making it slower for a person to respond to sudden changes in their environment, such as a pedestrian crossing the road or another vehicle stopping abruptly.

7. **Conclusion**:
- Due to these impairments—loss of judgment, coordination, and increased reaction time—a drunken person should not drive a vehicle as it poses a significant risk to themselves and others on the road.
