Two other members were severely injured, while the other two members and two support staffers suffered minor injuries. They are being treated at a hospital.
The accident occurred as a van carrying them crashed into a protective wall on the shoulder of the expressway.
The vehicle, a Hyundai Grand StarRex, may have skidded on a wet road, a police officer said, adding that the police are investigating the exact cause of the accident.
