A devastating vehicle fire involving a tanker created havoc on the Pennsylvania Turnpike late Saturday morning.
At least one vehicle turned into a rolling inferno on Interstate 476 shortly before 11 a.m., shutting down all lanes between Mid-County and Lansdale.
Social media images and videos show a large cloud of black smoke rising from the scene and blanketing the highway with debris.
Authorities have yet to release any official information about injuries, how many vehicles were involved or what caused the fire, but there is fear that multiple people were hurt.
