Accident Reconstruction Services
Scientific precision for every type of collision.
Accident Reconstruction Services We Provide
THE TRUTH IS IN THE PHYSICS.
GrayMatter Group provides accident reconstruction services for attorneys, insurers, corporations, and public agencies. We examine physical and electronic evidence to evaluate how a collision occurred and explain what the available information can—and cannot—establish.
An assignment begins with the questions that matter: vehicle speed and movement, collision sequence, impact location, visibility, braking, or the consistency of competing accounts. The scope follows the evidence and the qualifications needed for the work. Review our team’s biographies and curricula vitae.
Evidence and methods
Scene measurements, photographs, vehicle damage, video, witness accounts, and electronic records are compared rather than treated as interchangeable sources. Calculations and models must fit the available evidence. Our explanations identify assumptions, uncertainty, and limitations; a police-report diagram or a single recorded value does not replace a reconstruction.
Depending on the assignment, work may include vehicle and scene inspection, speed and time-distance analysis, collision-sequence evaluation, visibility assessment, and technical exhibits. The available vehicle systems and retained events determine whether electronic data can be retrieved. We offer EDR and black box data retrieval and analysis and commercial truck accident reconstruction.
Planning a case review
Send the collision date and location, vehicle details, current storage locations, known deadlines, and the questions you need answered. Useful materials include reports, photographs, original video files, diagrams, existing downloads, and prior inspection reports. Tell us if a vehicle may be repaired, released, or disposed of so that inspection priorities can be discussed promptly.

Did You Know?
There are 3 factors in every collision: Human factors, Environmental factors and Mechanical factors; There are also 3 collisions within every collision: Vehicle versus object, occupants versus the interior of the vehicle and its contents and bodily organs versus the skeletal structure.
Statistically, the safest day of the week to drive is Tuesday.
On Fridays, you are most likely to be involved in a non-fatal collision.
On Saturdays, you are most likely to be involved in a fatal collision.
The peak period for both fatal and nonfatal crashes is 4:00 p.m.–7:59 p.m. (often cited as the single most dangerous window due to heavy commuting traffic, fatigue, and decreasing visibility as daylight fades in many seasons).
- The 6:00 p.m.–9:00 p.m. window accounts for around 18% of crash deaths.
- Approximately one-third (33%) of all crash deaths occur between 3:00 p.m. and 9:00 p.m.
- Evening commute hours (roughly 3–7 p.m.) account for over 22% of fatalities in some analyses.
- Nighttime hours (midnight–4:00 a.m.) carry a much higher fatality rate per mile driven, though fewer total crashes occur due to lower traffic volume.
