Recent incidents of drug-related driving accidents in South Korea—such as a fatal crash involving a drugged driver in a Porsche—have intensified the urgency to address drug driving. In response, police and other agencies are collaborating to create scientific standards that would help determine when a person is unfit to drive due to drug effects. Currently, there are no clear legal criteria established as there are for drunk driving, which is defined by specific blood alcohol concentration levels.

During a recent meeting involving the National Forensic Service, the Korea Road Traffic Authority, and the Supreme Prosecutors' Office, officials discussed the need to implement a blood concentration standard for drug driving similar to that for alcohol. Last year marked a notable increase in the number of driver’s licenses revoked due to drug driving offenses—an increase of approximately 45.4%. The lack of objective standards for assessing impairment from drug use poses challenges for law enforcement and creates ambiguity in legal proceedings related to drug driving.

Going forward, the police plan to establish legal guidelines that define acceptable blood drug levels and determine when a driver may legally be considered impaired. The National Forensic Service will prioritize research related to the most common drug involved in these cases, zolpidem, and setting corresponding blood concentration limits. The intent is to create a clear and enforceable framework for assessing drug driving akin to the existing regulations for alcohol-related offenses, ultimately aiming to enhance public safety on the roads.
