Police say a semi truck’s brakes malfunctioned at an intersection on Friday afternoon, leading to an 8 car pile up that caused multiple injuries.

The accident happened on Friday, November 17th at approximately 1:00 p.m. in Churchill, Pennsylvania.

Police say the big rig took the William Penn Highway exit off of Interstate 376 and was traveling down a hill when its brakes failed. The semi truck then careened down the hill and crashed into a line of cars stopped at an intersection, leading to a pile up of at least 8 vehicles.

11 people were injured in the accident. 7 people were taken to the hospital with minor injures, and two people were taken with serious non-life-threatening injuries.

The truck driver was not hurt in the accident.

William Penn Highway, otherwise known as Route 22, has been shut down in both directions at Interstate 376 as crews work to clear the debris and officers investigate the incident. It is expected to be closed for an “extended period of time.”
