California Highway Patrol were getting calls of an overturned semi. The truck was currently blocking the ramp connecting eastbound Hwy 138 to the southbound I-15. CHP said the truck overturned around 12:37am on Friday, May 10, 2024, and spilled its contents, which were not reported, onto the right shoulder.

CHP issues a Sig Alert at 1:17am for one lane and the onramp to southbound I-15. The Sig Alert was lifted at 11am. This caused about two hours to pass the crash scene.

No injuries were reported, and the female driver and a child was not transported to the hospital.

We will update this story with more information when the CHP’s preliminary accident report is available. Additional details were limited at this time. This incident will be under investigation by the California Highway Patrol, Inland Office.
