LAS VEGAS (KLAS) — Drivers headed to Southern California on I-15 early Thursday morning experienced traffic delays before Jean, which is about halfway between Las Vegas and the California border.

Southbound I-15 was reduced to one lane after the cab of a big rig truck became separated from the tractor-trailer around 5 a.m. and then a vehicle struck the truck.

There were no reports of injuries. The southbound lanes fully reopened around 8:30 a.m.
