Seoul Gangnam actor Lee Jae-ryong faces obstruction of breath-test charge in DUI case.
Seoul’s Gangnam Police have added a new charge to actor Lee Jae-ryong’s case, accusing him of obstructing a breath-alcohol test in connection with a drunk-driving incident.
Lee, 62, allegedly drove under the influence around 11 p.m. on the 6th near Samseong Jungang Station on Seoul Subway Line 9 in Gangnam, rammed a central divider, and fled the scene. He was arrested about three hours later, around 2 a.m. on the 7th, after staying at a friend’s home. At the time, his blood-alcohol level was reported to be at a threshold that would warrant a license suspension.

Police suspect Lee consumed more alcohol after the crash to hinder testing, a tactic referred to in Korean as “drinking to avoid testing.” They plan to estimate his BAC using the Widmark formula and will question accompanying people who were with him at the time.
In initial police interviews, Lee denied driving while intoxicated, saying he had been drinking after the accident. Later reports quote him as saying he had four cups of soju and drove, believing he had only lightly brushed the central divider.

The current Road Traffic Act punishes attempts to obstruct alcohol testing with 1 to 5 years in prison or fines from 5 million to 20 million won. The rule was created after a high-profile drunk-driving and flight case involving trot singer Kim Ho-joong and took effect in June last year.
For U.S. readers, the case highlights Korea’s stricter enforcement of DUI and test-obstruction laws, a trend that can affect international collaborations in the entertainment industry, cross-border talent engagements, and the risk management of American companies working in Korea. It also illustrates how Korean authorities apply BAC calculations in real-time investigations, a practice with global relevance as many markets tighten road-safety standards.
