Truck fire causes Melb traffic chaos

A garbage truck has burst into flames on Melbourne's Princes Freeway, forcing the closure of all city bound lanes.

There's heavy traffic near Werribee Zoo after the truck caught fire on Friday morning, with VicRoads advising drivers to avoid the area if possible.

A CFA spokesman said traffic was a "nightmare" and crews have to remove all the garbage from the truck before the fire can be completely extinguished.
