Can a person be arrested for DUI after using legal or illegal drugs?

A person can be arrested for DUI after using either legal or illegal drugs because the law does not differentiate between the two regarding impairment. If someone consumes substances that lead to impairment—whether these are illicit drugs, prescription medications taken incorrectly, or legal drugs that affect cognitive or motor skills—they may still be charged with DUI.

Impairment is key in DUI cases. A driver can be arrested if their ability to operate a vehicle safely is compromised, regardless of the legality of the substance used. Law enforcement evaluates impairment through various methods, including field sobriety tests and breath or blood tests, which can detect levels of substances in the body.

While some choices may suggest that only specific conditions warrant an arrest, the critical aspect is the presence of impairment caused by any substance, reinforcing that both legal and illegal drugs can lead to DUI charges.
