Accident Reconstruction

Definition

Accident reconstruction is a scientific process used to investigate and analyze how and why an accident occurred. Experts in this field use principles of physics, engineering, and vehicle dynamics to piece together the sequence of events leading up to a collision. By examining physical evidence, vehicle damage, skid marks, road conditions, and electronic data, reconstructionists can determine factors like speed, point of impact, and driver behavior at the time of the crash.

How It’s Used in Personal Injury Cases

Accident reconstruction becomes critical in cases where fault is disputed or the circumstances of the crash are unclear. Insurance companies, attorneys, and courts rely on reconstruction experts to provide objective, evidence-based opinions about what happened. These experts often testify at trial and produce detailed reports with diagrams, animations, and calculations that help judges and juries understand the mechanics of the collision.

In trucking accidents, reconstruction is particularly valuable because commercial vehicles are often equipped with electronic logging devices (ELDs) and event data recorders that capture crucial information about speed, braking, and driver inputs in the seconds before impact.

Practical Example

Consider a case where a motorcyclist is struck by a car making a left turn. The driver claims the motorcyclist was speeding and appeared out of nowhere. The motorcyclist insists they were traveling at the speed limit. An accident reconstructionist examines the damage to both vehicles, measures the length and pattern of tire marks on the road, and downloads data from the car’s airbag control module. Their analysis reveals that the motorcyclist was traveling at 38 mph in a 40 mph zone and that the driver failed to yield. This evidence contradicts the driver’s account and supports the motorcyclist’s claim.

Why It Matters to Your Case

Accident reconstruction can make or break a case where liability is contested. A well-supported reconstruction report can establish that the other party was at fault, counter false narratives from the defense, and dramatically increase the value of your claim. Conversely, if the other side hires a reconstructionist and you don’t, their version of events may go unchallenged. In complex or high-value cases—especially those involving serious injuries or fatalities—investing in a qualified reconstruction expert is often essential.

Key Takeaway

Accident reconstruction uses science and physical evidence to determine how a crash occurred and who was at fault. In disputed liability cases, a reconstruction expert’s findings can be the deciding factor in proving your claim.
