It was gathered that the articulated vehicle was loaded with bags of grains and human beings and was descending a hill on the dilapidated road when it crashed into a ditch in the afternoon.
Eyewitnesses said when the trailer, which was moving out of Jos, crashed, it spilt its contents in the ditch, leaving many of the victims dead on the spot.
The Sector Commander of the Federal Road Safety Corps in Plateau State, Mr Godwin Alphonsus, confirmed the accident in Jos on Thursday evening.
