A big rig was headed west on Route 22 outside of Pittsburgh when disaster struck early this morning. The tractor-trailer slammed into a car at Cloverleaf Drive intersection, barreled into the median and then "T-boned a white pickup truck," according to KDKA TV.

Inside the car was a woman who witnesses said appeared to have head injuries. A Westmoreland County official said three people were injured in the truck accident, with one of them in critical condition.

The TV station reported that at around 6 a.m. the tractor-trailer slammed into at least six other vehicles in a Salem Township car lot before it turned onto its side. The owner of the lot said he did not know how much damage was done, but added that his top concern was for the victims of the crash.

"The biggest concern is for the victims," he said, "the people that were involved in this. Just hoping that they’re OK."

The driver of the pick-up truck was air-transported to UPMC Presbyterian Hospital with injuries reported to be critical.

Officials did not say why the big rig hit the other vehicles.

We know that in similar situations, some truck drivers are fatigued and should not be behind the wheel, while in other circumstances, the large vehicle is going too fast for conditions and cannot be stopped quickly.

No matter who is at fault or why, there will be difficult injuries to overcome for some people involved in this accident about an hour east of Pittsburgh. We wish quick and full recoveries to all.

As always, our offices are available to victims of truck accidents who must explore their legal options in order to pay for medical bills, lost income and other damages.
