Mark Jensen was driving home from Gulfstream Aerospace on a Tuesday evening in July 2026, eastbound on I-16 near Pooler, Georgia, in his 2023 Honda Accord. The sky was still bright, traffic was light, and then his life was shattered. An illegally parked, unlit tractor-trailer on the shoulder became an invisible wall in the twilight, causing a horrific tractor-trailer underride accident on I-16 that left Mark with a catastrophic injury. A single moment of negligence can absolutely lead to a lifetime of struggle, but legal recourse is available.
Key Takeaways
- Proper lighting and safety guards on tractor-trailers, which are federally mandated, can prevent most underride accidents.
- The force of an underride collision means victims often sustain severe brain, spinal cord, and internal organ injuries.
- You have to act fast to preserve evidence, identify all liable parties, and pursue fair compensation under Georgia law.
- Under Georgia’s modified comparative negligence rule (O.C.G.A. Section 51-12-33), you get nothing if you’re found 50% or more at fault.
- Expert witnesses like accident reconstructionists and medical specialists are non-negotiable for establishing fault and calculating the true cost of damages in these cases.
The Scene of the Accident: I-16 Eastbound, Pooler, Georgia
A newer Honda Accord with all the safety bells and whistles is no match for the unforgiving mass of a commercial truck. The front of Mark’s car slid straight under the trailer’s rear, the impact shearing the roof off to the B-pillar. Pooler Fire Department and Chatham County EMS were on scene in minutes, finding Mark unconscious and trapped inside what was left of his car. The Georgia State Patrol’s investigation immediately noted the lack of proper reflective tape and, critically, the absence of a working Rear Impact Guard (RIG), what we call a Mansfield bar. That absence was central to the entire legal case.
In my career, I’ve seen more accident scenes than I can count, but underrides are different. They have a unique kind of horror. It’s hard to forget the way a car just disintegrates under a trailer. The physics are just brutal. A car’s crumple zones, the very things designed to save you in a head-on crash, are rendered completely useless because the impact point is too high. The passenger cabin takes the entire hit. That’s exactly what happened to Mark.

At Memorial Health University Medical Center in Savannah, Mark was rushed into emergency surgery for a severe traumatic brain injury (TBI), multiple spinal fractures, and massive internal bleeding. The initial prognosis was grim, and his wife, Sarah, and their two kids began the awful waiting game that families in these situations know too well. A team of neurosurgeons and orthopedic specialists did everything they could to stabilize him, but the damage was deep. Doctors confirmed what everyone feared: permanent neurological deficits and partial paralysis that would change his life forever. And almost immediately, the medical bills started piling up, a constant, ugly reminder of the financial cost of this tragedy.
Hit as a pedestrian?
Even if you were jaywalking, you may still have a valid claim. Most victims don’t know this.
A catastrophic injury is a life sentence for the victim and their entire family. These are injuries involving the brain or spinal cord that result in long-term or permanent disability. The Centers for Disease Control and Prevention (CDC) data shows that TBIs are a major cause of ER visits, hospital stays, and deaths every year, often leaving survivors with a lifetime of cognitive, emotional, and physical problems. Mark’s case was a textbook example of the worst-case scenario.
Working through the Legal Field: Identifying Negligence and Liability
Sarah called us within days, focused on Mark’s care but terrified by the coming financial storm. The first thing we did was get our investigative team to the I-16 site while the GSP was still working its own report. Our people documented everything, photographing the trailer and combing through the police findings. The smoking gun was the non-compliant Rear Impact Guard. Under 49 CFR Part 393.86, the Federal Motor Carrier Safety Administration (FMCSA) has very specific rules for the strength and dimensions of these guards for the exact purpose of preventing underrides. The trailer, owned by “TransCorp Logistics,” didn’t come close to meeting them.
On top of the faulty guard, the driver had parked on the shoulder without using emergency lights or reflective triangles, a direct violation of O.C.G.A. Section 40-6-202, which governs parking outside of business districts. So we had two clear points of failure: a defective safety device and a driver who was breaking the law by parking negligently. This gave us a very strong liability case against the trucking company and potentially the driver himself.
Building the Case: Evidence and Expert Testimony
Building the case required a multi-pronged attack. First, we gathered every medical record, rehab plan, and long-term care projection for Mark. We brought in life care planners and economists to put a real number on the total damages, lost wages, future medical costs, pain and suffering, and the complete destruction of his quality of life. The numbers are staggering. Lifetime care for a TBI like Mark’s can easily run into the millions.
Next, we hired accident reconstructionists. These are the experts who analyze impact dynamics, vehicle speeds, and collision angles to prove exactly how a working underride guard would have prevented his car from ever going under the trailer. They also created simulations showing how impossible it was to see the unlit trailer at dusk. Their findings showed the direct link between the company’s negligence and Mark’s injuries.
Finally, we put the truck driver and execs from TransCorp Logistics under oath for depositions. This is where you find out about maintenance logs, driver training (or lack thereof), and company safety culture. We quickly uncovered a pattern of deferred maintenance across TransCorp’s fleet and lax enforcement of parking rules for their drivers. This kind of systemic failure strengthened our argument for punitive damages under Georgia law (O.C.G.A. Section 51-12-5.1).
The Road to Resolution: Settlement and Compensation
Unsurprisingly, the trucking company’s first offer was low. They tried to blame Mark, claiming he should have seen the parked truck. It’s a classic defense tactic in Georgia, leaning on the modified comparative negligence rule (O.C.G.A. Section 51-12-33) that can reduce a claimant’s award or bar it completely if they are 50% or more at fault. We flatly rejected their argument, countering with our expert analysis showing the unlit trailer and defective guard were the direct causes. Their blame-the-victim defense fell apart when confronted with the evidence of their own multiple federal and state safety violations.
With a jury trial in Chatham County Superior Court looking more and more like a bad bet for them, TransCorp and their insurance company finally came to the table. After some hard-fought negotiations, they agreed to a substantial settlement. The settlement provided the financial security for Mark’s lifelong medical care, the necessary adaptive equipment and home modifications, and compensated him for his lost earning potential and immense suffering. It gave Sarah and the kids the resources they needed to manage Mark’s long-term care and try to find a new normal.
Mark’s case shows why you have to move fast. Evidence in trucking accidents has a very short shelf life. We have to secure the truck’s black box data, the driver’s logbooks, and all maintenance records immediately. Any delay gives the other side an opportunity for that evidence to get “lost” or “accidentally” destroyed. I’ve seen it happen, hesitating to call a lawyer can absolutely tank your case before it even starts.
Conclusion: Protecting Victims of Trucking Negligence
Mark Jensen’s catastrophic injury from the tractor-trailer underride accident on I-16 is a brutal lesson in the consequences of commercial trucking negligence. If you or your family are facing a life-altering event like this, you have to get legal help right away to protect your rights, preserve evidence, and get the compensation you need for the long road ahead. For anyone in this situation, knowing the common mistakes to avoid in car accidents is critical for the success of your claim.
What is a tractor-trailer underride accident?
An underride accident happens when a smaller vehicle like a car slides underneath a large truck or trailer, which often shears the car’s roof right off. These accidents are so dangerous because the car’s safety features, like its crumple zones, are bypassed, leading to devastating injuries or death.
What safety devices are designed to prevent underride accidents?
The main safety device is the Rear Impact Guard (RIG), also known as a Mansfield bar. Federal regulations (49 CFR Part 393.86) have specific strength and size requirements for these guards to stop a car from sliding underneath a trailer. Side underride guards are also being developed and pushed for.
What types of injuries are common in underride accidents?
Because the passenger compartment takes a direct hit, injuries are horrific: severe traumatic brain injuries (TBI), spinal cord injuries causing paralysis, decapitation, internal organ damage, and multiple fractures. These catastrophic injuries almost always mean permanent disability and the need for lifelong care.
Who can be held liable in a tractor-trailer underride accident?
Liability can hit multiple parties. This includes the truck driver for things like fatigued driving or illegal parking, the trucking company for bad hiring or poor maintenance, the trailer owner, and even the manufacturer if the underride guard was defective. Identifying every responsible party is how you maximize compensation.
How does Georgia law address comparative negligence in accident claims?
Georgia uses a modified comparative negligence rule (O.C.G.A. Section 51-12-33). If a claimant is found partially at fault, their damages are reduced by their percentage of fault. The catch is, if the claimant is found to be 50% or more at fault, they are completely barred from recovering any money at all.
