SOUTH EL MONTE, Los Angeles County, CA, Sept. 22, 2026 — A motorcyclist was seriously hurt Monday afternoon, September 21, in a multi-vehicle crash on eastbound State Route 60 near Santa Anita Boulevard, the California Highway Patrol reported.
The crash was first reported as involving a motorcycle, a silver Toyota Prius and a black Nissan Sentra, blocking multiple lanes of the freeway, according to the CHP traffic log. Early radio traffic described a rider down and moving, with two vehicles involved. Later updates from callers at the scene described a big rig and two motorcycles involved, along with another vehicle, though the CHP had not confirmed a revised count of vehicles as of the log's most recent entries.
The motorcyclist was reported down in the roadway. Los Angeles County Fire Department units responded, and the rider was taken to a hospital, described in dispatch traffic as having major injuries. The extent of those injuries has not been confirmed by officials.
Authorities closed lanes on eastbound SR-60 near Santa Anita Boulevard while crews cleared the scene. A tow truck was called to remove at least one vehicle, and CHP's Freeway Service Patrol also responded before later closing out its assignment. The roadway was reported clear by mid-afternoon.
The CHP has not released the cause of the crash or confirmed how many vehicles were ultimately involved. The incident remains under investigation.
We hope those who were hurt recover fully and quickly.
What Makes Motorcycle Crashes on Freeways So Severe
A motorcycle has no frame, doors or airbags around the rider. When there is a crash, or when a rider goes down after contact with another vehicle, there is no metal shell absorbing the hit before it reaches the person. The rider's body and the pavement do most of the work that a car's crumple zone and safety cage would otherwise do.
Speed differences matter as much as contact itself. On a freeway, closing speeds are 60 mph or higher even in daytime traffic, and a motorcycle can be knocked down, thrown, or run over by trailing vehicles that can't stop in time. Weight is also a factor: a loaded semi truck or full-size sedan outweighs a motorcycle by a wide margin, so even a glancing hit can send the smaller vehicle and its rider tumbling in the roadway.
Helmets, jackets and boots reduce the severity of some injuries but they cannot substitute for the enclosed structure a car provides. According to the California Office of Traffic Safety, 33 motorcyclists who died were not wearing helmets in 2023, a reminder that protective gear lowers risk but does not eliminate it.
Frequently Asked Questions
How do left-turning vehicles cause crashes with motorcycles?
A common pattern involves a car turning left across an intersection or merge point without seeing an oncoming motorcycle because its narrower profile is harder to spot or its speed is misjudged.
What can drivers do to watch for motorcycles?
Checking mirrors and blind spots an extra time, allowing more following distance, and scanning twice before turning or changing lanes can help drivers notice a motorcycle before it's too late.
What should a rider do after a motorcycle crash?
If possible, move to a safe location away from traffic, call 911, and seek medical evaluation even if injuries seem minor, since some injuries from a fall or impact are not immediately obvious.
Are motorcycle crashes more common at intersections?
Intersections and merge areas, where vehicles cross paths or change lanes, account for a large share of motorcycle collisions because they require other drivers to judge a motorcycle's speed and distance correctly.
What to Do After a Motorcycle Crash in South El Monte, CA
Anyone involved in or witnessing a motorcycle crash in South El Monte should call 911 right away so paramedics and CHP officers can respond. If you're the rider or a passenger, try to stay still until medical responders arrive unless remaining in the roadway puts you at further risk.
Get a full medical evaluation even if you feel able to walk away, since adrenaline can mask pain from fractures or internal injuries. Take photos of the scene if it's safe to do so, and get contact information from any witnesses. A copy of the CHP incident report can help clarify what happened once the investigation concludes.
