Which of the following is a form of substance that can lead to impaired driving?

Over-the-counter medication can significantly impair driving abilities, making it a valid form of substance that leads to impaired driving. Many over-the-counter medications contain active ingredients that can cause drowsiness, decreased reaction time, or altered cognitive functioning. For instance, antihistamines, certain pain relievers, and cold medications may impair a driver's concentration and motor skills, similar to the effects of alcohol or illegal drugs.

Impaired driving can occur from a wide range of substances, which is why recognizing that over-the-counter medications play a role in this issue is crucial for both safety and legal awareness. It emphasizes the need for drivers to be cautious and informed about the effects of any substance they consume, including those that are easily accessible without a prescription.
