Which statement is true regarding driving while taking medications?

The statement that most cold medications can make a person drowsy is true because many over-the-counter cold medications contain antihistamines, which are known to cause drowsiness as a side effect. This drowsiness can impair a person's ability to focus and react quickly while driving, similar to the effects of alcohol or other sedatives. Because of this, it's essential for drivers to be aware of how any medication they take can affect their driving abilities.

While some medications might not necessarily cause drowsiness, the impact on driving can vary widely from one individual to another. Therefore, it's crucial to read labels and warnings and consult healthcare providers about any potential side effects when taking medications, especially those that are known to affect alertness.
