Which of the following actions should not be taken while driving?

Taking medications that could impair you is an action that should never be taken while driving because these substances can significantly affect your cognitive and physical abilities. Impairment can manifest as slowed reaction times, decreased awareness, and impaired decision-making, which can lead to dangerous driving situations. Understanding the effects of medications is crucial; even over-the-counter drugs can cause drowsiness or distraction.

In contrast, adjusting mirrors before you start driving is not only a necessary safety measure but should be done while the vehicle is stationary. Using turn signals is a crucial part of safe driving practices, communicating your intentions to other road users. Eating a snack may pose distractions but is generally considered less hazardous than driving under the influence of impairing medications. Prioritizing safety on the road includes ensuring that your mental and physical state is fully conducive to driving, making it imperative to avoid any medication that could impair your abilities.
