UPDATE:
CHP announced on Thursday that a car driving recklessly on the I-15 south led to the crash involving a tractor-trailer.
In a release, CHP says around 1:35 p.m. Thursday, a Infiniti G35, a Toyota Camry and a tractor-trailer were traveling on the I-15 Southbound when the Infiniti was seen driving recklessly.
As a result, the Infiniti crashed into the Toyota and the tractor-trailer, according to CHP.
The tractor-trailer overturned, causing the saddle tank to rupture and diesel fuel to spill and enter a storm drain.
CHP says the fuel did not affect any nearby waterways, but the recovery and cleanup procedures temporarily closed three lanes on the freeway for hours, and the left lane of the Friars Road off-ramp.
The lanes were not reopened until Thursday, around 1:00 a.m.
The cause and sequence of events are under investigation. If anyone witnessed this crash, call CHP San Diego Area at (858) 293-6000.
According to CHP, a small blue vehicle was reportedly speeding and hit a semi truck, causing it to partially flip.
The crash happened just after 1:30 p.m. on the southbound lanes of the I-15, at Friars Road.
CHP closed lanes three, four, five, and the Friars offramp due to the crash.
Hazmat crews also responded to the scene to clean up a large amount of diesel that spilled onto the lanes, according to CHD.
There is no timeline for when the lanes will be reopened.
This is a developing story, and will be updated with more details.
