Two big rig trucks collided at the Pilot truck stop in Castaic early Tuesday morning, spilling 100 gallons of diesel fuel from a broken saddle tank onto the private parking lot.

No injuries occurred, said Inspector Sam Padilla of the L.A. County Fire Department.

The department dispatched a hazardous materials team at 6:54 a.m. to contain the spill.  

Responders poured sand around the spill to prevent it from flowing, Padilla said.

Units remained on the scene until 3:15 p.m.

No one was injured and traffic was not affected, officials said.
