Zoltán János Tamás, the managing director of Volmer-Tours and Tamás-busz, said the companies have policies with three different insurers. He declined to reveal the names of the companies while the accident is under investigation.
Tamás expressed his condolences to the families of the victims of the crash.
The bus, carrying more than 50 passengers returning from holiday in Croatia, crashed on the M7 motorway about 70km from Budapest early Sunday morning. It broke through a barrier, hit a pillar on an overpass, and rolled over, killing eight people and seriously injuring eight.
