What is the classification for taking a prescription drug containing codeine while driving?

Taking a prescription drug containing codeine while driving is classified as a DUI because codeine can impair a person's ability to operate a vehicle safely. Even if the drug is legally prescribed, it can still affect reaction times, judgment, and overall driving capabilities. Laws in many jurisdictions hold drivers accountable for their mental and physical state while driving, regardless of whether a substance is legal or prescribed. Therefore, if the drug leads to impairment, it can result in a DUI charge. This classification emphasizes the importance of being aware of how medications might influence driving abilities.
