SIMI VALLEY, Ventura County, Calif., Oct. 2, 2026 — A crash involving a dump truck and two passenger cars blocked westbound State Route 118 near Kuehner Drive on Thursday afternoon, October 1, according to the California Highway Patrol.
The CHP said the collision was first reported as a traffic hazard shortly before 3:30 p.m., after one vehicle was found stopped in the number four lane. Within minutes, dispatch logs show the incident grew to involve three vehicles, described as a gray Honda CR-V, a green Honda Civic and a dump truck. The agency later classified it as a crash with minor injuries.
Officials said the dump truck ended up facing the wrong way in the number four lane after the crash. Ventura County Fire Department crews responded to the scene, and at least one person was taken to a hospital in Simi Valley. Lanes on westbound SR-118 were affected while crews worked the scene, with reports describing delays stacking up behind the collision.
A tow company was called to remove vehicles from the roadway, and the lanes reopened once the wreckage was cleared.
The cause of the crash remains under review. Our thoughts are with those who were injured, and we wish them a full recovery.
What the Numbers Show About Large-Truck Crashes
According to the National Highway Traffic Safety Administration, 76 percent of fatal crashes involving large trucks occurred on weekdays in 2023. That figure reflects how closely truck crash patterns track commercial driving schedules: dump trucks, delivery rigs and freight haulers are overwhelmingly on the road Monday through Friday, during the same hours as commuter traffic.
That overlap matters because it puts large, slow-maneuvering vehicles in the same lanes as higher volumes of passenger cars during peak hours. A dump truck merging, slowing or stopping on a freeway during a weekday afternoon creates a mismatch in size and stopping distance that can be hard for other drivers to judge in time.
Weekday concentration also shapes how often these crashes happen on highways and arterial roads rather than local streets, since most commercial truck routes run through exactly those corridors. Crash reconstruction specialists often look first at timing and traffic volume when reviewing a truck-involved collision, because both are so closely tied to when these crashes cluster.
Frequently Asked Questions
What makes truck accidents more dangerous than car crashes?
The size and weight difference between a large truck and a passenger vehicle means more force is transferred to the smaller vehicle in a collision. Trucks also take longer to stop and require more space to maneuver.
What are a truck's blind spots and why do they matter?
Large trucks have substantial blind spots on both sides, directly behind the trailer, and immediately in front of the cab. Vehicles in these zones may be invisible to the truck driver, which is why sudden lane changes or merges near a truck carry added risk.
What is an underride crash?
An underride crash happens when a smaller vehicle slides partially or fully beneath a truck's trailer during a collision, often because the trailer sits higher off the ground than a car's crumple zones are designed for.
What are common causes of large-truck accidents?
Driver fatigue, following too closely, equipment failure, and difficulty judging traffic flow when merging or changing lanes are frequently cited factors in large-truck crash investigations.
What to Do After a Truck Accident in Simi Valley, CA
If you're involved in a crash with a commercial truck in Simi Valley, move to a safe location if possible and call 911 right away. Even if injuries seem minor, it's worth getting checked by a medical professional, since some injuries from truck collisions don't show symptoms immediately.
Exchange information with all drivers involved and, if you're able, take photos of the vehicles, the roadway, and any visible damage. Ask for the responding agency's report number so you can follow up later. Keeping a record of what happened while details are fresh can make it easier to sort out insurance and medical questions down the road.
