When Multiple Parties Share Responsibility: Holding All Defendants Accountable in an Equipment Failure Case
A defective tire-sliding lever trapped our client’s arm for several minutes, and our investigation identified multiple defendants responsible for the equipment failure and secured settlements from all of them.
A Dangerous Moment at a Delivery Site
In September 2021, our client, a commercial truck driver, was at a warehouse delivery site in Santa Fe Springs, California when another driver experienced mechanical difficulties with his semi-truck. The tire-sliding lever—a mechanical component that allows truck tires to slide along the axle—wasn’t functioning properly.
Our client did what many experienced truckers do: he stepped in to help a fellow driver troubleshoot the problem. While assisting from outside the truck, the tire-sliding lever suddenly and unexpectedly released.
In an instant, our client’s arm became trapped and pinned between the trailer skirt and the tires. He remained trapped, in excruciating pain, for approximately two to five minutes until the other driver could maneuver the truck to free him.
Those minutes must have felt like an eternity. The physical pain of having an arm crushed between heavy equipment. The fear of not knowing if he would lose the arm. The helplessness of being unable to free himself. For a commercial truck driver whose livelihood depends on physical capability and the ability to operate vehicles safely, this catastrophic injury threatened not just his immediate health but his entire career.
Uncovering Multiple Responsible Parties
The immediate question after the accident was obvious: whose equipment failed, and who was responsible for maintaining it safely?
But as we began investigating, we discovered the answer wasn’t simple. The truck, its equipment, and its maintenance involved multiple entities with different roles and responsibilities. We couldn’t just pursue the driver of the truck—we needed to identify everyone who had a duty to ensure that tire-sliding lever was safe and functional.
Our investigation revealed multiple defendants who shared responsibility for the dangerous condition that trapped our client’s arm. Through document analysis, discovery, and persistent investigation, we identified separate entities with overlapping responsibilities for the truck’s equipment and maintenance.
Building the Case Against Multiple Defendants
We filed our initial complaint in February 2022, naming the defendants we had identified through our preliminary investigation. But we didn’t stop there. As we continued gathering evidence through discovery—reviewing ownership documents, maintenance records, service contracts, and conducting depositions—we uncovered additional parties who bore responsibility for the equipment failure.
In December 2022, we filed a First Amended Complaint with additional allegations based on what we’d learned. By November 2023, our investigation had revealed another entity whose relationship to the truck and its equipment created liability. We amended our pleadings again to add this defendant.
This iterative process—investigate, discover new information, amend pleadings, pursue additional responsible parties—is essential when equipment failures involve complex business relationships. We weren’t going to settle for pursuing only the most obvious defendant when our investigation showed that multiple parties had failed in their duties.
The Medical and Career Impact
The injury our client sustained went beyond the immediate trauma of having his arm trapped. As a commercial truck driver, his profession demands significant physical capability: steering large vehicles, climbing in and out of truck cabs, securing loads, performing pre-trip inspections, and handling various manual tasks throughout the day.
An arm injury of this severity—crushed between heavy truck components for several minutes—creates both immediate damage and potential long-term limitations. Soft tissue damage, potential nerve involvement, reduced strength and range of motion, and ongoing pain can all impact a driver’s ability to safely operate commercial vehicles and perform the physically demanding aspects of the job.
For someone whose entire livelihood depends on physical capability, this kind of catastrophic injury doesn’t just cause medical bills and pain—it threatens career viability and future earning capacity.
Securing Settlements from All Responsible Parties
By May 2024, we had developed strong evidence against all defendants. We served a policy limits demand on one set of defendants—the parties initially identified as responsible for the truck and equipment. This strategic move put them on notice that their insurance coverage would not adequately compensate our client for his catastrophic injuries.
On July 29, 2024, these defendants accepted our policy limits demand through their insurance carrier.
But accepting one settlement didn’t mean we were finished.
Some firms might have taken the policy limits payment and closed the file. We continued pursuing the other defendants we had identified. Just because one group had paid their limits didn’t absolve other responsible parties of their share of accountability.
On October 24, 2024, we reached a separate settlement with the additional defendants we had added to the case through our amended pleadings.
The final settlement agreement was executed November 2024—just weeks before the case was scheduled for trial. By pursuing all defendants through to resolution, we ensured that every party who bore responsibility for the defective equipment contributed to compensating our client. The combined confidential settlements from multiple defendants provided just compensation from all responsible parties.
Resolving the Full Picture
Our client also had a related workers’ compensation claim for the injury. As part of achieving a comprehensive resolution, we coordinated the dismissal of the workers’ compensation proceeding. This ensured our client received optimal compensation from the responsible third parties without the complications of parallel proceedings or workers’ comp liens reducing his recovery from the defendants whose equipment had failed.
Why Pursuing All Defendants Matters
This case demonstrates why identifying and pursuing all responsible parties is essential in catastrophic injury cases. When multiple defendants share responsibility, each should contribute to compensating the victim. One defendant’s insurance limits may not adequately compensate a catastrophically injured person—identifying all responsible parties increases available compensation and ensures complete accountability.
For our client facing career-threatening injuries, every settlement mattered. By pursuing all defendants through amended pleadings and separate settlement negotiations, we maximized his recovery from every party whose failure contributed to trapping his arm.
How We Identified Multiple Defendants
Finding all responsible parties in this case required reviewing truck registration and ownership documents, analyzing maintenance contracts and service records, conducting depositions to uncover business relationships, and persistently amending pleadings as new information emerged. In equipment failure cases, the investigation doesn’t stop at the most obvious defendant—it continues until you understand every entity that had responsibility for keeping that equipment safe.
When Equipment Failures Involve Multiple Parties
At Adamson Ahdoot, we handle equipment failure and catastrophic injury cases throughout California. These cases often require identifying multiple defendants with overlapping responsibilities, coordinating civil liability and workers’ compensation claims, negotiating with multiple insurance carriers, and pursuing all responsible parties even after initial settlements.
When equipment fails catastrophically, the investigation must uncover all parties who had responsibility for maintaining that equipment safely. Our client’s case demonstrates the importance of that thorough, persistent approach.
Your Case May Involve Multiple Responsible Parties
If you’ve been seriously injured by defective equipment or an equipment failure, don’t assume the most obvious defendant is the only one responsible. Multiple entities may share responsibility for equipment maintenance, safety, and operations.
Thorough investigation to identify all responsible parties, strategic pursuit of policy limits, willingness to amend pleadings as new information emerges, and persistent advocacy to hold every responsible party accountable—that comprehensive approach ensures catastrophically injured clients receive full compensation from all parties who contributed to their injuries.
This case resolved with confidential settlements in 2024. This article presents the case in general terms without disclosing specific parties, settlement amounts, or detailed terms, in accordance with settlement agreement provisions.
