Queensland driver's dash camera captures two separate crashes in motorway pile-up

A Queensland motorist's front and rear dash cameras have captured two separate crashes during a six-vehicle pile-up on the Logan Motorway.

The terrifying incident began on Monday morning when a B-double travelling westbound ploughed into the back of oncoming cars.

The driver's front camera shows the truck failing to slow down before smashing into the slowing vehicles.

The car the truck slams into no doubt saw the impending disaster in their rear-view mirror.

"Woah. Wholly s---. Wholly f---. I'm in the middle of a massive pile-up on the arterial road," one driver can be heard saying in their dash-cam footage of the crash.

"I'm in the middle but I'm safe, but pity everyone around me."

As the trucks and cars came to a stop, another dash camera pointing behind the pile-up captured the driver of another truck trying to avoid the carnage ahead.

The rig driver slammed on his breaks and spun out, but managed to come to a stop before hitting the carnage ahead.

In a call to emergency services, the driver whose cameras are filming can be heard describing his incredible luck.

"I'm lucky I'm like in this little centre spot, everything's smashed front and behind me," he says.

Three people were taken to hospital.

Police investigations are continuing.
