Investigations into the cause of a crash that involved two heavy vehicles near Condah this morning are still ongoing.
At about 7.50am, a B-Double truck travelling at 60 to 70 kilometres an hour north on the Henty Highway, after turning onto the thoroughfare, was rear-ended by a heavy rigid delivery truck.
The truck at the rear than lost control losing the braking system and came to a halt on the left side of the road, having run into an unoccupied grader belonging to the Glenelg Shire.
The passenger of the delivery truck was trapped and it took emergency services about 20 minutes to get the 46-year-old Reservoir man out of the wreckage.
The B-Double driver, a 38-year-old man from Portland, walked away unharmed as did the 33-year old-driver of the delivery truck.
