A serious freeway collision involving a big rig and a passenger vehicle shut down lanes on the westbound 210 Freeway in San Dimas, sending one person to the hospital and causing significant traffic disruptions during the morning commute, according to local reports.
Crashes involving commercial trucks often result in severe injuries due to the sheer size and weight disparity between big rigs and passenger vehicles. This incident is a reminder of how quickly routine freeway travel can turn dangerous.
What Happened on the 210 Freeway
According to reports from ABC7, the crash occurred on the westbound 210 Freeway near the Lone Hill Avenue exit in San Dimas.
Preliminary information from the California Highway Patrol (CHP) indicates that a Toyota sedan became lodged underneath a big rig (semi-truck) following the collision. The circumstances leading up to the crash have not yet been fully explained.
Emergency responders arrived at the scene and worked to extricate the driver from the damaged vehicle. The injured individual was transported to Pomona Valley Hospital Medical Center, where they were treated for moderate injuries.
Emergency Response and Traffic Impact
The crash prompted a large emergency response, including CHP officers, firefighters, and paramedics. Several westbound lanes of the 210 Freeway were closed for an extended period as crews assisted the injured driver, cleared debris, and removed the damaged vehicles.
Morning commuters experienced major delays, with traffic backing up for miles while tow trucks and investigators worked at the scene. Freeway collisions involving big rigs often require lengthy closures due to the complexity of vehicle recovery and evidence documentation.
Investigation Still Ongoing
As of the latest update, the cause of the crash remains under investigation. CHP has not yet released details regarding:
- Whether speed played a role
- Whether either driver made an unsafe lane change
- Whether mechanical issues were involved
- Whether driver fatigue or distraction may have contributed
In serious truck accidents, investigators often review vehicle data, driver logs, dash-cam footage, roadway conditions, and witness statements before reaching conclusions. These investigations can take weeks or longer.
Why Big Rig Accidents Are Especially Dangerous
Accidents involving tractor-trailers and other commercial trucks are often far more severe than typical car crashes due to several factors:
- Extreme weight and momentum of big rigs
- Longer stopping distances compared to passenger vehicles
- Risk of underride collisions, where smaller vehicles slide beneath trucks
- Increased likelihood of crushing injuries and vehicle intrusion
Even at moderate speeds, these crashes can result in life-altering injuries, extensive vehicle damage, and prolonged road closures.
Legal Issues Raised by Commercial Truck Crashes
Truck accidents are legally complex and often involve multiple potentially responsible parties, including:
- The truck driver
- The trucking or freight company
- Vehicle owners or maintenance providers
- Parts manufacturers
- Cargo loaders or logistics companies
Unlike ordinary car accidents, commercial trucking cases may involve federal safety regulations, driver log requirements, and corporate insurance policies, making early investigation especially important.
What to Do After a Big Rig or Semi-Truck Accident
If you or a loved one is injured in a collision involving a commercial truck:
- Seek immediate medical care, even if injuries seem minor
- Cooperate with law enforcement at the scene
- Preserve evidence, including photos, videos, and witness information
- Avoid giving recorded statements to trucking insurers without legal guidance
- Consult an experienced truck accident attorney early
Critical evidence—such as electronic logging data and maintenance records—can be lost or overwritten if not preserved quickly.
