True or False: Driving a motor vehicle after taking substances which alter the central nervous system can have side effects which include impaired attention, reaction time, and vision.

The statement is true because substances that alter the central nervous system, such as alcohol, prescription medications, or illicit drugs, can significantly impact a person's cognitive and physical abilities. These substances can lead to diminished attention, slower reaction times, and impaired vision, all of which are critical for safe driving.

For instance, attention is essential for processing information from the road, other vehicles, and pedestrians. If a driver is unable to focus, they may miss important signals or hazards. Similarly, reaction time is crucial when responding to unexpected situations, such as another driver suddenly stopping or a pedestrian entering the roadway. Impaired vision can affect a driver's ability to see clearly or judge distances correctly, further increasing the risk of accidents.

Understanding the effects of these substances is vital for promoting road safety and making informed choices about driving, highlighting the importance of never driving under the influence.
