HIGHLAND PARK, Los Angeles County, Calif., Nov. 3, 2026 — A crash involving several vehicles sent at least one person to a hospital on Monday afternoon, November 2, on southbound State Route 110 just north of Avenue 43 in Highland Park, according to the California Highway Patrol.
The CHP said the collision was first reported shortly before 1 p.m. as a crash between a gray vehicle and a black vehicle blocking the slow lane. A caller to the agency then reported a black Honda Civic had collided with a brown Lexus IS350, with both vehicles blocking additional lanes, the agency's traffic log shows. The reporting party also said vehicles had sustained damage.
Within about 20 minutes, CHP upgraded the incident from a crash with no reported injuries to one involving an injury requiring medical response. A California Highway Patrol unit was still holding all lanes as of 1:20 p.m. while crews worked the scene. The extent of the injury had not been released as of this writing.
Freeway Service Patrol crews also responded and later closed out their portion of the call.
The cause of the crash has not been determined. We hope those who were hurt recover fully and quickly.

Frequently Asked Questions
Are secondary crashes common after an initial wreck like this one?
Yes. When vehicles are left blocking travel lanes, approaching drivers usually have little time to react, which can lead to a follow-up collision before responders arrive or lanes are cleared.
What makes crashes involving several vehicles harder to investigate?
Investigators have to sort out the sequence of impacts, which vehicle struck which, and whether one collision triggered another, usually using damage patterns, witness accounts and any available video.
What typically causes a pile-up involving multiple cars?
Common factors include one vehicle stopping or slowing suddenly, a driver following too closely, reduced visibility, or a driver failing to notice a collision ahead in time to stop safely.
Why do chain-reaction crashes happen on freeways?
Dense, fast-moving traffic leaves drivers less room to brake or steer around a hazard, so when one vehicle stops unexpectedly, it can trigger a chain of rear-end or sideswipe collisions behind it.
