Two inches of vehicle crush can matter a lot: crush analysis is an accident-reconstruction method that uses the amount and pattern of metal deformation to estimate impact force, speed change, and sometimes how a crash unfolded.

After a wreck, investigators measure how deeply a bumper, door, quarter panel, or frame was pushed in, then compare those measurements with known stiffness data for that vehicle or a similar model. The goal is not to guess from a photo. It is to turn physical damage into numbers that help explain whether a hit was minor, moderate, or severe, and from what direction the force likely came. In Montana crashes, that can be especially useful when black ice on I-90, crosswinds on I-15 or US-2, or a wildlife strike leaves conflicting stories about lane position, braking, or loss of control.

For an injury claim, crush analysis can support or challenge arguments about causation, fault, and the seriousness of the collision. A low-speed defense, for example, may not hold up if the measured crush shows a stronger impact than the other side claims. It can also help connect crash forces to body injuries, though vehicle damage and human injury do not always track neatly; bodies are less predictable than sheet metal. In Montana, most injury lawsuits are governed by a 3-year deadline under Mont. Code Ann. § 27-2-204, so preserving the vehicle before it is repaired or salvaged can be critical evidence for a personal injury claim or wrongful death claim.
