Which is a factor that does NOT influence driving ability?

The choice pertaining to healthy lifestyle choices is correct because maintaining a healthy lifestyle has a positive impact on driving ability. Engaging in regular physical activity, eating a balanced diet, and getting adequate sleep contribute significantly to overall health, alertness, and cognitive function. These factors can enhance a driver's focus, reaction time, and decision-making skills, which are crucial for safe driving.

In contrast, the other options—illegal drugs, prescription drugs, and over-the-counter drugs—are known to affect driving ability negatively. These substances can impair judgment, reduce coordination, and slow reaction times, increasing the risk of accidents. Thus, while the other factors impede driving performance, a healthy lifestyle supports and enhances one's capability to drive safely.
