WESTMONT, Los Angeles County, Calif., Oct. 10, 2026 — Three vehicles collided early on Friday morning, October 9, at the intersection of S Normandie Avenue and W 103rd Street in Westmont, according to the Los Angeles County Sheriff's Office. At least part of the roadway was blocked as crews responded.
The crash was reported around 3:20 a.m. and initially described as involving a white truck and a gray BMW. The Sheriff's Office later reported three vehicles were involved, though a full description of each was not immediately available.
Los Angeles County Fire Department personnel were called to the scene shortly after the initial report. The extent of any injuries has not been released, though dispatch logs indicate at least one person was being transported for medical evaluation.
A tow request for a Ford F150 was logged at the scene, suggesting at least one vehicle needed to be removed from the intersection. The crash blocked a right-hand lane for a period of time, dispatch notes show.
The California Highway Patrol and the Sheriff's Office have not released further details on how the crash occurred. The collision remains under investigation.

Multi-Vehicle Crashes and the Toll on Truck Occupants
According to the National Highway Traffic Safety Administration, 365 large-truck occupants were killed in multi-vehicle crashes involving large trucks in 2023. That figure reflects how commonly pickups and larger trucks end up in chain-reaction wrecks rather than single-vehicle incidents, since multi-vehicle crashes make up the bulk of truck-involved fatalities nationwide.
Intersections add another layer of risk. When a truck collides with a passenger car at a signal or stop, the mismatch in size and weight usually means the smaller vehicle absorbs most of the damage. Overnight hours compound this, since visibility is lower and other drivers may be slower to notice a developing hazard ahead.
Multi-vehicle collisions also tend to involve more unknowns in the first hours after the crash. Investigators typically need time to sort out which vehicle struck which, and in what order, before a full narrative of the collision is released.
Frequently Asked Questions
What should I do if I'm stopped near a crash on the highway or a busy roadway?
Turn on hazard lights, stay inside the vehicle if it's safe to do so, and move as far from traffic lanes as possible. Call 911 if you haven't already and wait for responders before attempting to move a damaged vehicle.
How does low visibility contribute to multi-vehicle pile-ups?
Darkness, fog, or glare can delay a driver's reaction time enough that a single stopped or slowed vehicle triggers a chain of collisions. Reduced visibility is a common factor in overnight multi-vehicle crashes.
Why is following distance so important in preventing these crashes?
Extra space between vehicles gives drivers more time to brake or steer around a hazard. Tailgating is one of the most common contributing factors cited in rear-end and chain-reaction collisions.
Are secondary crashes common after an initial wreck?
Yes. Vehicles stopped or slowed near the original crash site are vulnerable to being struck again, which is why responders usually work quickly to block lanes and warn approaching traffic.
What to Do After a Multi-Vehicle Crash in Westmont, California
If you're involved in a multi-vehicle crash, move to a safe location if possible and check on others involved before anything else. Call 911 and wait for law enforcement to arrive and document the scene, even if damage looks minor at first.
Seek a medical evaluation soon after the crash, even without obvious injuries. Adrenaline can mask pain from impacts, and some injuries don't show symptoms until hours later.
Keep a copy of the incident or CAD report once it's available, along with any photos taken at the scene. These records can matter later, whether for insurance claims or simply understanding what happened.
