A man exiting his disabled pickup truck was killed today on the 118 Freeway in Chatsworth when a car hit the truck, pushing it into the man and flinging him over the center divider to the other side of the freeway, where he was struck by a motorcycle.

The crash was reported at 5:47 a.m. on the westbound 118 Freeway at Topanga Canyon Boulevard, the Los Angeles Fire Department said.

The man who died at the scene was in his 40s, the coroner’s office reported. His name was withheld pending family notification.

According to the preliminary investigation, a pickup truck became disabled on the carpool lane of the westbound freeway and the motorist got out, the CHP reported.

That’s when a westbound car hit the pickup truck, and the impact pushed the truck into the man, who was flung over the center divider and into the path of an eastbound motorcycle, which struck him, the CHP reported.

The car’s driver and the motorcyclist were treated for injuries that were not believed to be life-threatening. Three lanes were closed in each direction on the 118 Freeway while crews worked to clear the scene.

As a result of the crash, there was a “significant” impact on traffic on the 118 Freeway in both directions, the fire department said, adding the L.A. County Fire Department also responded to the scene.

A SigAlert was issued at 6 a.m. for the carpool, No. 1, No. 2 and No. 3 lanes of the westbound and eastbound freeway at Topanga, the California Highway Patrol said.

Around 10 a.m., the SigAlert was canceled, the CHP said.

Tuesday’s crash comes two days after a traffic accident involving a wrong-way driver killed two people around 12:24 a.m. Sunday on the 118 Freeway east of De Soto Avenue.
