What are the effects of using medication while driving?

Using medication while driving can significantly impair a driver's reaction times and judgment, making option C the correct choice. Many medications can cause side effects such as drowsiness, dizziness, or reduced cognitive function, all of which negatively impact a person's ability to operate a vehicle safely. It is crucial for drivers to be mindful of how medications, whether prescription or over-the-counter, might influence their physical and mental abilities behind the wheel, as these impairments can lead to an increased risk of accidents.

Other options suggest that medication has no impact or even enhances driving skills, which is misleading. The potential for impairment is a serious concern, and recognizing the risks associated with medication can help ensure safer roads for everyone.
