What effect can combining substances have regarding DUI?

Combining substances such as alcohol and drugs can significantly increase impairment and the risk of an incident while driving. When various substances are ingested together, their effects can amplify each other, leading to greater levels of impairment than what would occur from using each substance separately. For example, alcohol may enhance the sedative effects of certain prescription medications, resulting in decreased reaction times, impaired judgment, or difficulty concentrating—all of which are critical for safe driving. This synergistic interaction raises the potential for accidents, making it crucial to understand the heightened risks associated with combining substances.
