In the context of driving, which skill is negatively impacted by alcohol use?

1. Comprehension

2. Attention

3. Coordination

4. All of the above

The correct answer is: All of the above

Alcohol use has a comprehensive impact on various cognitive and motor skills that are crucial for safe driving. Comprehension is affected as a driver may have difficulty processing information or understanding what is happening on the road. This impairment can delay the reaction to signage, signals, or the behavior of other road users. Attention is also significantly compromised under the influence of alcohol. It reduces a driver’s ability to sustain focus on the task of driving, leading to distractions and lapses in concentration. This diminished attention can cause the driver to miss critical cues and delays in responding to potential hazards. Coordination is perhaps one of the most visibly affected skills when a person is under the influence of alcohol. It impacts fine motor skills required for controlling a vehicle, such as steering, braking, and accelerating. Impaired coordination increases the likelihood of accidents due to poor handling of the vehicle. Given that alcohol negatively affects all these skills—comprehension, attention, and coordination—it is accurate to conclude that the correct answer encompasses the collective impairment of these essential driving skills.
