The Deadliest Truck Crash Type. Multiple Parties Are Responsible.
Truck underride crashes — where a passenger vehicle slides beneath a trailer — are among the most deadly crash types on Florida roads, frequently producing decapitation-level injuries or instant fatalities. Federal underride guard standards exist specifically to prevent these crashes. When they fail — or when carriers operate without compliant guards — the liability is clear and catastrophic. Shiner Law Group pursues carriers, vehicle owners, and manufacturers.
Underride Crashes Almost Always Involve Catastrophic or Fatal Injuries
The physics of underride crashes mean that survival with serious injuries is actually the better outcome. These cases require maximum liability pursuit — including product liability against trailer manufacturers whose guards fail to perform.
Underride Guard Condition Must Be Documented Immediately
The condition of the truck's rear or side underride guard at the time of the crash is decisive evidence. Carriers may repair or replace damaged guards before inspection — an attorney must immediately document the guard's pre-repair condition.
Product Liability May Apply Against Trailer Manufacturers
When a federally compliant underride guard fails to prevent cabin intrusion at foreseeable crash speeds, the trailer manufacturer faces product liability claims in addition to the carrier's direct negligence. Both claims are pursued simultaneously.
Truck Underride Liability in Boca Raton — Carrier Negligence & Manufacturer Defects
Truck underride crashes are a product of physics: when a passenger vehicle collides with a large trailer — from the rear or side — the car's hood and roof pass beneath the trailer's cargo floor, which then intrudes into the passenger compartment at occupant head height. The result is injuries that are almost uniformly catastrophic: decapitation, traumatic brain injury, and fatal crush injuries to front-seat occupants are the documented outcomes of underride crashes at highway speeds.
Federal Motor Carrier Safety Administration (FMCSA) regulations require rear underride guards on all trailers — steel bars mounted at the trailer's rear designed to stop a vehicle before it slides beneath the trailer. The problem: the current federal standard (FMCSA 393.86) requires guards to withstand only 22,500 lbs. of force, and tests are conducted at low speeds. Real-world underride crashes on I-95 occur at 65+ mph — forces that exceed the current federal standard's design parameters. When a compliant guard fails to prevent cabin intrusion at realistic highway speeds, the trailer manufacturer faces product liability claims.
Side underride guards — which prevent cars from sliding beneath a trailer from the side — are currently voluntary, not federally required. Carriers who voluntarily install side guards but fail to maintain them, or who operate without side guards on routes known for intersection crossing patterns, face negligence claims when side underride crashes result. Our attorneys investigate every guard-related decision the carrier made.
For families of fatally injured victims: Underride crashes are disproportionately fatal. Florida's Wrongful Death Act allows surviving family members to pursue funeral costs, lost financial support, loss of companionship, and mental pain and suffering. The two-year statute of limitations applies from the date of death. Contact Shiner Law Group immediately — underride crash investigations must begin immediately to document guard condition before repairs are made.

What Causes Truck Underride Crashes — Guard Failures & Carrier Negligence
Underride crashes happen when protective systems fail — either because they were never installed, were poorly maintained, or were designed to standards below what real crash physics require.
Damaged or Non-Compliant Rear Guards
Rear underride guards can be damaged in docking incidents, routine backing operations, and minor collisions — and left unrepaired for months. A damaged guard that fails to meet FMCSA 393.86 standards is a direct cause of underride injury, and the carrier's failure to maintain it is documented negligence.
No Side Underride Guards
Side underride guards are voluntary under current federal standards — but carriers who operate in high-intersection routes and choose not to install available side guards face negligence claims when side underride crashes result. The voluntary nature of the standard does not eliminate the common law duty of care.
Defective Guard Design — Manufacturer Liability
When a federally compliant guard fails to prevent cabin intrusion at foreseeable highway crash speeds, the trailer manufacturer may face product liability claims for designing a guard that meets the letter but not the purpose of the federal standard. Product liability experts analyze guard performance relative to real-world crash forces.
Sudden Stops or Slow-Moving Trucks at Night
Rear underride crashes frequently involve trucks that stop or slow unexpectedly on highways — particularly at night when trailer lighting is the only visibility aid. Malfunctioning trailer lights are a documented contributing cause of rear underride crashes on I-95.
Inadequate Trailer Lighting & Reflectors
FMCSA requires trailers to maintain functional reflectors and clearance lights visible at 500 feet. Defective or missing rear lighting dramatically increases rear underride risk at night — and the carrier's failure to maintain compliant lighting is a direct cause of resulting crashes.
Lane Changes & Intersection Crossing
Side underride crashes occur when a truck changes lanes into a passenger vehicle or crosses an intersection in front of an approaching vehicle. The truck's trailer — not its cab — becomes the contact point, and without side guards, cabin intrusion is the predictable result.

Steps That Protect Your Claim
Emergency Medical Response is the Priority
Underride crashes produce the most severe injuries of any crash type. Call 911 immediately and ensure emergency medical personnel are at the scene before any other actions.
Document the Guard Condition Before the Truck Moves
The condition of the truck's rear underride guard is the most critical evidence in an underride case. Photograph the guard — its damage, its position relative to the ground, and any visible compliance markings — before the truck is moved.
Get Law Enforcement to Document the Scene
Request that the responding officer specifically document the truck's underride guard condition, trailer lighting, and any guard damage in the official report. This creates an official record before the carrier can make repairs.
Preserve All Physical Evidence
Do not allow your vehicle to be repaired or scrapped before your attorney's accident reconstructionist has inspected it. The damage pattern on your vehicle is direct evidence of how the underride occurred.
Contact an Attorney Before Speaking to the Carrier
The carrier's legal team will arrive quickly. Do not speak to their representatives, provide a statement, or accept any settlement discussions without your own attorney present.
