What are the effects of prescription medications on driving?

Prescription medications can significantly impair vision, reaction time, and cognitive functions, making option C the correct choice. Many prescription drugs, especially those that are sedating or have central nervous system effects, can lead to drowsiness, decreased alertness, and slower reflexes. This impairment can result in difficulties with focusing and visual acuity, as well as challenges in making quick decisions which are vital while driving.

Furthermore, the effects of these medications are not confined to nighttime driving alone; they can affect a driver's capabilities at any time of day. Such impairments may not be immediately obvious to the driver, which can lead to an increased risk of accidents. It is essential for drivers taking prescription medications to understand the potential side effects and how they might influence their ability to drive safely.

Understanding these effects is crucial for maintaining road safety and making informed decisions about driving after taking any medication.
