Los Angeles, CA - Multiple Injuries Occur in Seven-Car Crash on 405 Fwy at Atlantic Ave

Los Angeles, CA (March 27, 2025) – A chain-reaction crash involving at least seven vehicles on Thursday morning on the 405 Freeway in Long Beach prompted the closure of several lanes.

The crash occurred in the first lane on the southbound side of the freeway, near Atlantic Avenue. The number and severity of injuries were not immediately known. Firefighter-paramedics responded to the scene, and one car apparently struck a semi-truck as drivers tried to make their way past the wreckage.

The big rig was cleared from the middle lane as the pileup of other vehicles remained along the center median. Southbound traffic, however, remained backed up for miles amid the morning commute. The cause of the crash was unknown, but officers are urging any witnesses to come forward with information that could aid in the investigation.

Our thoughts are with the victims and their families during this time. We hope for a fast and complete recovery for the injured individuals.

Multi-Vehicle Collisions in California

Multi-vehicle accidents—sometimes called chain-reaction or pile-up collisions—are some of the most chaotic and dangerous types of crashes on California roadways. These incidents often involve three or more vehicles and can occur on highways, at intersections, or even in heavy traffic conditions. The complexity of these crashes makes them challenging when it comes to determining fault and seeking compensation.

There are many factors that can lead to multi-vehicle accidents. Common causes include speeding, tailgating, distracted driving, and sudden lane changes. Poor weather conditions, low visibility, and road hazards can also play a role. In many cases, one driver’s initial mistake—such as failing to brake in time or drifting out of a lane—can trigger a chain reaction that quickly escalates as other vehicles get caught in the crash.

These accidents can lead to a wide range of injuries, from whiplash and broken bones to traumatic brain injuries and long-term disabilities. Because multiple parties are involved, victims often face complex questions about who is responsible, whose insurance applies, and how to pursue a fair recovery.

Dealing with multiple drivers, insurance companies, and possibly conflicting accounts can make the claims process stressful and confusing. Having someone who understands California traffic laws and insurance procedures can make a major difference in your ability to recover compensation for your injuries, property damage, and other losses.
