What does "under the influence" mean in the context of driving?

"Under the influence" in the context of driving specifically refers to being affected by drugs or alcohol, which can significantly impair a person's ability to operate a vehicle safely. This condition can lead to a loss of coordination, decreased reaction times, and impaired judgment, increasing the risk of accidents on the road.

Understanding this term is critical for drivers, as it underscores the importance of making responsible choices regarding substance use before getting behind the wheel. While being affected by prescribed medication can also impair driving ability, the broader concept of "under the influence" specifically encompasses both recreational and prescribed substances that can affect one's capacity to drive safely.
