405 Freeway Crash: Multi-Vehicle Collision Causes Major Delays, Injuries

A major multi-vehicle collision on the southbound 405 Freeway near Brentwood, California, resulted in significant traffic delays and injuries early Wednesday morning, July 2, 2025. The incident, which involved a semi-truck and two other vehicles, prompted the closure of several lanes and left three individuals hospitalized, one with severe injuries.

Incident Overview

The collision occurred just after 2 a.m. south of Getty Center Drive, according to the California Highway Patrol (CHP). Preliminary reports indicate that a semi-truck and two passenger vehicles were involved in the crash. The circumstances leading to the collision are currently under investigation by the CHP.

Emergency responders arrived at the scene to provide medical assistance and manage the traffic situation. Three individuals were transported to local hospitals for treatment of their injuries. Tragically, one of the injured individuals sustained the loss of a leg as a result of the crash, according to CHP reports.

The severity of the collision necessitated the closure of most southbound lanes of the 405 Freeway, a major artery in the Los Angeles area. The closures caused substantial traffic congestion and delays for commuters during the morning hours. The exact duration of the lane closures remains unclear as authorities continue to investigate the scene and work to clear the wreckage.

Location of Incident Raises Concerns

Notably, this incident occurred on the same stretch of the 405 Freeway where a Los Angeles Police Department (LAPD) sergeant was fatally struck in a separate crash just last week. This proximity raises concerns about potential safety issues on this particular section of the freeway and may prompt further review by transportation and law enforcement agencies.

Legal and Safety Implications of Multi-Vehicle Collisions

Multi-vehicle collisions, often referred to as pile-ups, can present complex legal challenges due to the number of parties involved and the potential for multiple causes. Determining liability in such cases requires a thorough investigation to identify the factors that contributed to the crash. These factors may include driver negligence, such as speeding, distracted driving, or impaired driving, as well as roadway conditions, vehicle malfunctions, and other external influences.

In California, drivers have a legal duty to operate their vehicles with reasonable care to prevent harm to others. Failure to do so constitutes negligence, which can form the basis of a personal injury claim. When a driver’s negligence causes a collision resulting in injuries or fatalities, the injured parties or their families may be entitled to compensation for their losses.

Potential Liable Parties

In a multi-vehicle collision, multiple parties may share responsibility for the incident. Potentially liable parties could include:

  •   The drivers of the vehicles involved: Any driver whose negligence contributed to the crash may be held liable for damages.
  •   The trucking company (in cases involving commercial vehicles): If a semi-truck is involved, the trucking company that employs the driver may be liable if the driver’s negligence caused the crash. This could include negligent hiring practices, inadequate training, or failure to maintain the vehicle properly.
  •   Vehicle manufacturers: In cases where a vehicle defect contributed to the crash, the manufacturer may be held liable under product liability laws.
  •   Government entities: If dangerous road conditions, such as inadequate signage or poorly maintained roadways, contributed to the collision, a government entity responsible for maintaining the roads may be liable.

Legal Recourse for Victims

Victims injured in multi-vehicle collisions have the right to pursue legal action to recover compensation for their damages. These damages may include:

  •   Medical expenses: Costs associated with treatment for injuries, including hospital bills, doctor visits, physical therapy, and medications.
  •   Lost wages: Compensation for income lost as a result of being unable to work due to injuries.
  •   Property damage: Costs to repair or replace damaged vehicles and other personal property.
  •   Pain and suffering: Compensation for the physical pain, emotional distress, and mental anguish caused by the injuries.
  •   Loss of consortium: In cases of severe injury or fatality, family members may be entitled to compensation for the loss of companionship, support, and intimacy.

Importance of Legal Representation

Given the complexities involved in multi-vehicle collision cases, it is crucial for injured parties to seek legal representation from a skilled personal injury attorney. An attorney can conduct a thorough investigation of the accident, gather evidence to support the claim, identify all potentially liable parties, and negotiate with insurance companies to secure a fair settlement. If a settlement cannot be reached, an attorney can file a lawsuit and represent the client’s interests in court.
