What is the term for driving under the influence of controlled substances?

The term "Drug DUI" refers specifically to driving under the influence of controlled substances, including illegal drugs as well as prescription medications that affect a person's ability to operate a vehicle safely. This terminology is essential in law enforcement and legal contexts as it signifies that a driver is impaired not solely by alcohol but by other substances that can lead to unsafe driving behaviors.

The other choices do not accurately capture this specific scenario. "Alcohol Impairment" pertains only to the influence of alcohol, which excludes any other types of substances. "Substance Abuse Driving" is a broader term that may encompass various aspects of substance use-related driving offenses but is not a formal legal designation used to indicate drug-induced impairment. "Controlled Substance Offense" typically refers to a violation involving illegal drugs in general but does not specifically highlight the act of driving under their influence. Therefore, "Drug DUI" is the precise term to denote the act of driving while impaired by controlled substances.
