Operating a vehicle while impaired by any substance, whether it is alcohol, prescription drugs, over-the-counter medications, or illegal drugs, is against the law. These substances can alter your perception, reaction time, and decision-making capabilities, endangering not only the driver but also passengers and others on the road. Regardless of whether a medication is legally prescribed, if it impairs your ability to drive safely, it is unlawful to drive under its influence. Ensuring complete sobriety and clarity is mandatory for safe driving, emphasizing the importance of understanding how substances affect your driving capability.
