On 19 April 2007, almost two months after Super Junior-T's release of their first single "Rokuko", Eunhyuk was involved in a car accident, along with Shindong, Leeteuk, Kyuhyun, and two managers, when returning home following a recording of the radio show Super Junior Kiss the Radio. While they were on the highway, the front left tire burst as the driver was switching lanes and the van ran into the guard rail/median on the driver's side and skidded for about 30 metres. At some point, the momentum caused the van to flip over on its right side. While Shindong and Eunhyuk suffered minor injuries, Leeteuk and Kyuhyun sustained more serious injuries, which required both to be hospitalised.
