From a FB user:
TIB478M on 178, got pushed onto a
grasspatch by a huge CAT dump truck during their convoy... TIB478M
might have suffered a serious damaged on the right side as the
whole bus was tilted to the right... Happened not long ago...
However, it is still not known whether the convoy is legalised
with TP guarding them or an illegal movement on the road... CAT
might be in deep trouble for this...
