Main Roads warned motorists to take “extreme caution” when driving through the area and closed one lane, but then shut the entire freeway northbound and are advising motorists to take alternative routes.
It is understood the truck’s diver lost control of the vehicle early on Monday morningin the northbound lane just before Karnup Road.
It is not yet known if anyone was injured in the crash.
Traffic delays are expected into the morning.
