Impaired driving refers to operating a vehicle while under the influence of substances that affect a person's ability to drive safely. This includes alcohol, illegal drugs, and certain prescription medications. Impaired drivers may experience reduced coordination, slower reaction times, and impaired judgment, increasing the risk of accidents. Laws against impaired driving are enforced to protect public safety. Penalties for offenders can include fines, license suspension, and even jail time. Organizations like MADD (Mothers Against Drunk Driving) work to raise awareness about the dangers of impaired driving and promote safe driving practices.
