What a Crush Injury Is
A crush injury results from sustained compression of part of the body, rather than from a brief impact. In truck crashes it happens when a vehicle is pinned beneath a trailer, when an occupant compartment collapses, or when a person is caught between a trailer and a fixed object.
The distinction from ordinary trauma matters because compression damages tissue in a specific way: it interrupts blood supply, and muscle deprived of circulation begins to die. The longer the compression continues, the more tissue is affected — and the damage continues developing after the pressure is removed.
Two complications define this category, and both are why crush injuries are treated as their own emergency.
Compartment Syndrome and Crush Syndrome
Compartment syndrome occurs when swelling inside a closed muscle compartment raises pressure to the point that blood cannot enter. Because the compartment is bounded by fascia that does not stretch, the pressure has nowhere to go. Without surgical release — a fasciotomy — muscle and nerve tissue die within hours. It can develop after the initial injury, including after apparently successful treatment, which is why escalating pain out of proportion to the visible injury is a warning sign that must be acted on.
Crush syndrome is a systemic reaction. Damaged muscle releases myoglobin, potassium, and other substances, and when compression is relieved these enter the circulation in a surge. The result can include kidney failure and cardiac arrhythmia. This is the reason emergency crews sometimes stabilise and treat a trapped person before extricating them — releasing the pressure without preparation can be the more dangerous act.
The lasting consequences include chronic pain, permanent weakness and reduced function, nerve damage, contracture, and in the most severe cases amputation.

Which Truck Crashes Cause Crush Injuries
- Wide-turn and off-tracking collisions — where a person or vehicle is caught between a trailer and a curb, wall, or barrier. These occur at very low speed, which is why insurers characterize them as minor.
- Underride crashes — where a vehicle is trapped beneath a trailer.
- Rollovers — where a trailer comes down onto a vehicle.
- Lost load incidents — where heavy cargo falls onto a vehicle or person.
- Loading dock and backing incidents — frequently involving workers and pedestrians rather than other drivers.
The recurring theme is that impact speed is a poor guide to severity here. A person pinned by a slow-moving trailer can sustain catastrophic injury at speeds well under 10 miles per hour, and any argument that a low-speed collision cannot cause serious harm should be treated with skepticism in this category.
Florida Rules That Apply
| Rule | Effect on a crush injury claim |
|---|---|
| PIP and the 14-day rule | Fla. Stat. § 627.736 provides $10,000 with treatment required within 14 days — exhausted immediately by surgical care. |
| Permanent injury threshold | Fla. Stat. § 627.737. Nerve damage, permanent weakness, and fasciotomy scarring generally support it. |
| Scarring and disfigurement | Fasciotomy leaves substantial permanent scarring, which is independently relevant under the same statute. |
| Comparative negligence | Fla. Stat. § 768.81 — reduced by your fault share, barred above 50%. |
| Two-year deadline | For negligence claims arising after March 24, 2023 (HB 837). |
Low speed does not mean low severity in a crush injury.

What to Do After a Crush Injury
- Get medical care immediately — Florida’s PIP statute (Fla. Stat. § 627.736) requires initial treatment within 14 days to access your $10,000 in benefits.
- Report escalating pain immediately — pain out of proportion to the visible injury is the classic warning sign of compartment syndrome and is a surgical emergency.
- Do not accept a low-speed characterization of the crash from an insurer as a statement about your injury.
- Photograph the injury and any surgical scarring as it develops and matures.
- Document functional loss — grip strength, weight-bearing, endurance, and specific tasks now impossible.
- Complete rehabilitation and have any residual deficit formally measured.
- Do not settle early — nerve recovery, where it happens at all, takes many months to establish.
- Do not give a recorded statement to the trucking company’s insurer before speaking with an attorney.
