Pennsylvania State Police say the cause of a  Coyne Chemical tractor trailer overturning and closing roadways down for 14 hours was speeding while taking a turn onto a Turnpike ramp from I-95. 

The accident, which caused flammable fluids to leak out on to the roadway, brought busy rush hour traffic to a standstill, and brought out first responders from throughout Lower Bucks County, occurred just after 6 p.m Friday evening. 

The tractor trailer exited I-95 southbound onto Pennsylvania Turnpike at exit 42 southbound and was “driving too fast while negotiating a left curve,” police said. The truck fell on to its right side which on impact caused hazardous materials to leak out, state police said in a release.

Approximately 12o feet of guide rail was wrecked due to the crash, according to State Police, and one light post was damaged. 

The driver, identified as Jeffrey Coar, 37 was cited for a safe speed violation, according to a press release, and was taken to a medical facility for treatment.

Lower Bucks Source contacted Coyne Chemical representatives for comment about the accident, the company is based in the Croydon section of Bristol Township, and as of 5:30 p.m our call was not returned. 

Employees of the company were warned on Monday not to speak with the local press about the accident, multiple sources told the publication.
